Qatar’s Nasser Al-Attiyah and his French co-driver, Mathieu Baumel, successfully defended the Dakar title they won for TOYOTA GAZOO Racing (TGR) in 2022 when they brought their GR DKR Hilux T1+ over the finish line of the final stage of Dakar 2023 with a winning margin of 1 hour 20 minutes 49 seconds.
Although they had lost almost 6 minutes to the final stage leaders, they had already built up a comfortable lead from stage 3 to be able to take overall victory. For Nasser, it’s a fifth win in the event, while Mathieu’s tally is now 4 victories. The pair have won 3 times for Toyota, with the latest victories coming in a back-to-back. Nasser’s two earliest wins were win Volkswagen (2011) and MINI (2015)
Formula 1 fans will know that Audi will be taking part in the sport for the first time from the 2026 season. Audi will compete as a factory team together with its strategic partner, Sauber. Both parties are now busy developing the power unit for the F1 racing car at Audi’s Competence Centre Motorsport.
It will be some time before the first prototypes start to race around the test track but there is one place where you will be able to see the Audi F1 car in action – and even drive it – long before it starts its first F1 race. Thanks to EA Sports, the Audi F1 racing car will be available in the F1 22 racing game from Codemasters.
When the Audi RS Q e-tron started the 2022 Dakar Rally, there were many unknowns for the Audi Sport team. Audi Sport is no stranger to tough off-road racing – having been successful in the World Rally Championship in the 1980s with its Quattro – but the rallycar for the Dakar Rally was something entirely new. It ran primarily on electricity, something they had not done before in off-road competition.
Though the team did not win on that first attempt, it claimed 4 stage victories but more importantly, the experience helped the engineers improve the prototype rallycar in many areas. “We learned a lot at rallies and tests in our first year and implemented everything consistently – technically, logistically and organizationally. The close cooperation between Audi Sport, drivers, co-drivers and Team Q Motorsport is paying off and running very smoothly,” said Uwe Breuling, Head of Vehicle Operations.
In March 2022, the Audi RS Q e-tron won its first desert rally in Abu Dhabi, an important achievement for an electrically-powered vehicle. Audi was the first carmaker that committed to develop a viable alternative drive concept for the gruelling event, making it a pioneer in motorsport.
The original RS Q e-tron development had been rushed as it had to be done during the difficult period of the coronavirus pandemic in 2021 and limited testing opportunities. However, with the experience and learnings from that tough first event, Audi Sport’s engineers have developed a new and significantly improved prototype which will be entered in the 2022 Morocco Rally and the 2023 Dakar Rally.
“We’ve managed a good debut at the Dakar with the Audi RS Q e-tron and even our first stage victories in a motorsport discipline that is new to us,” said Rolf Michl, Managing Director of Audi Sport GmbH and responsible for motorsport at Audi. “The entire team is working excellently together and pulling in the same direction. As is usual at such an early stage, the drivers, co-drivers and technicians quickly agreed on the next development targets. We have summarized the result in a new evolution package – the RS Q e-tron E2.”
Main components of the first RS Q e-tron
Second phase of development program Reminiscent of the legendary Audi Sport quattro in its final development stage for Group B rallying in the 1980s, the body is completely new and features significantly enhanced aerodynamics. It also has a lower weight and centre of gravity.
“The Audi RS Q e-tron E2 does not adopt a single body part from its predecessor,” said Axel Loffler, Chief Designer of the RS Q e-tron. In order to comply with the prescribed interior dimensions, the cockpit, which was previously narrowly recessed towards the roof, is now significantly wider. The front and rear hoods have also been redesigned.
“We are now doing away with the underflow of the rear hood to the left and right of the B-pillars. In conjunction with modified lay-ups – optimized fabric layers of the composite materials – this solution reduces weight,” said Loffler.
The T1U prototypes will have to weigh 2,100 instead of 2,000 kgs in the future. Given that the first generation of the RS Q e-tron was overweight, it was still necessary to save several dozen kilograms. This is accompanied by the lowering of the vehicle’s centre of gravity.
New aerodynamic concept The aerodynamic concept in the area of the body below the hoods is completely new. This section is somewhat like the shape of a boat’s hull: its widest point is at the height of the cockpit, while the body tapers significantly towards the front and rear.
The designers dispensed with the part of the fenders that was behind the front wheels and formed the transition to the door. Internally, this structure was called the ‘elephant foot’ and as a result, it saved more weight and optimized the airflow.
“The aerodynamic aspect should not be underestimated in desert rallying either,” said Axel Loffler, Chief Designer of the RS Q e-tron. “Admittedly, the new cockpit dimensions mean that the body has a larger and therefore less favourable cross-section. Nevertheless, it was possible to reduce the overall aerodynamic drag by around 15%. But this does not change the top speed, which remains limited to 170 km/h in the regulations.”
Nevertheless, the improved airflow offers one major advantage. “It further reduces the energy requirements of the electrically powered car,” explained Loffler. “We implemented the aerodynamic calculations entirely using computational fluid dynamics. These computer simulations replace the time-consuming work in the wind tunnel and still deliver highly precise results.”
Simplified operation in the cockpit The drivers can look forward to their new workplaces. The displays are still in the driver’s field of view and located in the centre console in the usual style, and the central switch panel with its 24 fields has also been retained. However, the engineers have restructured the displays and controls.
They can also work much more easily when there is a puncture, which is not uncommon in off-road events. Simple, flat and easily removable body components replace the previous bulky covers for the spare wheels in the flanks. The new 10-spoke rims are much easier to handle, making the change of wheels safe and quick.
New operating strategies further improve the efficiency of the electric drivetrain. The drivetrain of the RS Q e-tron E2 comprises an energy converter consisting of an internal combustion engine and a generator, as well as a high-voltage battery pack. Two electric motors are used to power the front and rear axles.
Better energy management Energy management plays a crucial role here. The electronic control system of the complex electric drivetrain proved its worth in the first rally events and issues only occurred in extreme cases. At the Dakar Rally, for example, it was noted that there were short-term surpluses of power in situations where the wheels made less contact with the ground while jumping or on uneven terrain.
The so-called auxiliary consumers also benefit from optimized control. The servo pump, the air-conditioning cooling pump and the fans have a measurable impact on the energy balance. In the course of the debut season this year, the Audi and Q Motorsport rally team gained valuable experience that enables better assessment.
The air-conditioning system, for example, works so aggressively that it could cause the coolant to freeze when constantly running at its maximum output. In the future, the system will run in an intermittent mode. This saves energy, yet the interior temperatures only fluctuate slightly, even over longer periods.
“We have combined all the important lessons in a very short time. The result of our ideas is the E2 evolution,” says Uwe Breuling, Head of Vehicle Operations Audi Sport. “Our development team’s determined and cost-efficient work has prepared us perfectly for our second Dakar Rally.”
Audi has confirmed that it will race in the Formula 1 World Championship from the 2026 season, with Audi Sport being responsible for the activity. As a consequence, the high-performance division is discontinuing its LMDh project for endurance racing but will continue with the RS-Q e-tron project for the Dakar Rally. It will announce the team partner by the end of this year.
Audi recognizes Formula 1’s high popularity in its key markets as well as with young target groups. It has particular interest in the sport because it is seen as ‘a spectacular platform for the most demanding electrified racing cars in the world ‘and the brand will be able to show its ‘Vorsprung durch Technik’ in this highly competitive environment.
Formula 1 is watched globally and one of the sporting events with the highest reach in the world. In 2021, more than 1.5 billion TV viewers watched the races. On social media, Formula 1 is now experiencing the highest growth rates among the world’s most popular sports.
“Motorsport is an integral part of Audi’s DNA,” said Markus Duesmann, Chairman of the Board of Management of Audi AG. “Formula 1 is both a global stage for our brand and a highly challenging development laboratory. The combination of high performance and competition is always a driver of innovation and technology transfer in our industry. With the new rules, now is the right time for us to get involved. After all, Formula 1 and Audi both pursue clear sustainability goals.”
The key to getting involved is the world’s most popular racing series is the clear plan to become more sustainable and cost-efficient. The new technical rules, which will apply from 2026, focus on greater electrification and advanced sustainable fuel, areas which Audi has been active in developing.
In addition to the existing cap on costs for teams, a cost cap for power unit manufacturers will be introduced in 2023. Formula 1 has also set itself the ambitious goal of being a carbon-neutral racing series by 2030.
“In view of these major technological leaps that the series is making towards sustainability in 2026, we can speak of a new Formula 1. Formula 1 is transforming, and Audi wants to actively support this journey. A close link between our Formula 1 project and AUDI AG’s Technical Development department will enable synergies,” said Oliver Hoffmann, Member of the Board for Technical Development.
For 7 years (until 2021), Audi Sport was involved in the Formula E series with the ABT Schaeffler team. The team was the most successful in the all-electric single-seater series with 14 victories out of 84 races.
From 2026, the electric power output for the power units, consisting of an electric motor, battery, control electronics, and a combustion engine, will increase sharply compared to today’s Formula 1 drive systems. The electric motor will then be nearly as powerful as the combustion engine, which has an output of about 544 bhp. The highly efficient 1.6-litre turbocharged engines run on advanced sustainable fuel – also a prerequisite for Audi’s entry into the series.
Audi Sport to develop power unit
The hybrid power unit will be built at Audi Sport’s Competence Centre Motorsport in Neuburg an der Donau, not far from Audi’s headquarters in Ingolstadt, Germany. “For the development and manufacture of the Formula 1 powertrain, we will build on the valuable expertise of our motorsport employees, continue to invest in our motorsports center, and also recruit highly specialized professionals,” said Audi Sport Managing Director Julius Seebacht.
The facility already has test benches for F1 engine testing as well as for electric motor and battery testing. Additional necessary preparations are currently being made in terms of personnel, buildings, and technical infrastructure, with everything essential to be in place by the end of the year. A separate company was recently established for the power unit project as a wholly owned subsidiary of Audi Sport.
The Audi S1 e-tron quattro Hoonitron to be driven by Ken Block has been completed and will make its North American debut at the Rolex Motorsport Reunion later this month. This is the first time the drift artist is working with Audi after having long associations with Ford and Subaru.
Unlike all previous cars that Block has used, the S1 e-tron quattro – to be used in the next installment of his famous Gymkhana series, ‘Electrikhana’ – does not run on petrol because it has no combustion engine. Instead, it has dual motors powered by electricity, and Block will show that even with electrification, extreme performance is still possible.
Design of the S1 e-tron quattro Hoonitron was inspired by the legendary quattro S1 (below) that set a new record in the Pikes Peak Hillclimb in the 1980s.
Inspiration for the design of the one-off car came from the legendary quattro S1 rallycar that sped up Pikes Peak in record time. The entire development, including the technology, of the S1 Hoonitron was conducted by Audi Sport.
Audi Design was brought in for the styling work only in December 2021. Typically for a project of this magnitude, designers and engineers would spend a year or more just developing the concept. However, in the case of the S1 e-tron quattro Hoonitron, an accelerated timeline of just 4 weeks was targeted at the Audi Sport facility in Germany.
After about a month of labour-intensive work, the S1 Hoonitron was finalized. Block flew over to provide his input and also learn how to drive an all-electric car sideways and in circles. “I’m familiar with a wide variety of cars using internal combustion engines and transmissions, but there were a lot of new things for me to learn. Spinning into a donut at 150 km/h directly from standstill – just using my right foot – was an all-new experience for me! Our work was focused on getting the car and I used to each other. My thanks go to the whole Audi Sport squad for their outstanding teamwork,” he said.
“The S1 e-tron quattro Hoonitron combines a lot of what Audi was already famous for in the 1980s,” added Block. “For instance, the car’s spectacular aerodynamics have now been translated into a totally modern form. I think it’s cool that the Audi designers have been inspired by their own past and uniquely transferred the car’s technologies and appearance into the present.”
The S1 e-tron quattro Hoonitron brings electrification directly to the performance car enthusiast’s doorstep. Besides powerful electric motors, there’s all-wheel drive, a carbonfibre chassis, and incorporation of the full suite of safety standards as dictated by the FIA.
From 1984 to 1987, Walter Rohrl, as a member of the Audi Sport team, drove the original Sport quattro S1 during the Group B era of rallying. Audi had gained an unfair advantage in the early 1980s when it used the quattro all-wheel drive system in its rallycars. The ‘unfair advantage’ propelled the success of the brand in off-road, pavement, and track competitions alike, with significant performance benefits.
Today, the Audi quattro system has evolved with the latest technologies and credentials adapted from the world of motorsports. The modern interpretation, the S1 Hoonitron, serves as a nod to this significant period, while remaining sharply focused on the commitment toward electrification.
Ever since the Dakar Rally moved to Saudi Arabia from South America in 2020, Nasser Al-Attiyah has been trying harder to win the event as it is now held in the Arab world. He came very close to doing so in 2020 and 2021 and this year, again driving for TOYOTA GAZOO Racing, he finally captured the crown. The victory would also be a fitting welcome for the new President of the FIA, Mohammed Ben Sulayem from the United Arab Emirates, a former top rally driver.
This is the Qatari driver’s second victory for the team, having previously won the event in 2019. It is the fourth Dakar win for the ‘Prince of the Desert’, as the rally community has nicknamed him, the others being in 2011, 2015 and 2019. In the two earlier events, he was driving a Volkswagen and a MINI. Besides being a skilled rally driver, Al-Attiyah, 51, has also represented his country in clay pigeon shooting in the Olympics.
The result makes Al-Attiyah the second-most successful driver in the history of the event’s cars category, tied with Finland’s Ari Vatanen and only behind Stephane Peterhansel’s tally of 8 wins.
The vehicle they drove was the new GR DKR Hilux T1+ which conforms to the updated regulations for the T1 category. It features larger wheels and tyres, more wheel travel, and the 3.5-litre twin-turbo V6 engine that also powers the new Land Cruiser 300 GR Sport. The truck shares components with the race-proven Hilux that was first introduced in 2018, and won the race in 2019.
For Al-Attiyah and co-driver Mathieu Baumel, the final stage presented few real problems, despite challenging navigation. The pair had taken the lead in the rally during the opening stage of the event and were never in danger of relinquishing that position. They won the prologue for the 2022 edition of the rally on January 1, and powered to two more stage wins on their way to overall victory.
Their closest rival and runner-up were the pair of Sebastien Loeb and Fabian Lurquin of the ProDrive/Bahrain Raid Xtreme team which finished 27 minutes 46 seconds behind. However, the 9-time WRC champion from France lost 50 minutes in the early part of the rally with a broken driveshaft. Loeb did manage to bring the gap down to under 30 minutes by the end of the penultimate stage – before a penalty for speeding undid part of his good work.
Saudi Arabians were delighted to see their countryman also on the podium as Yazeed Al-Rajhi (below) with Michael Orr of the Overdrive Toyota team finished third. They had pushed their Toyota Hilux hard but were realistic enough to aim for second and lost out to Loeb by about 34 minutes.
A 16-time Dakar Rally participant, Orlando Terranova finished an impressive 4th to give the ProDrive/Bahrain Raid Xtreme team a finish among the Top 5 in the category. For South Africans Giniel de Villiers and co-driver Dennis Murphy, there were many highs and lows as the fought their way to 5th place, giving TOYOTA GAZOO Racing two placings in the Top 5 finishers.
All three electrically-powered Audi RS Q e-tron rallycars completed the event.
For the Audi Sport team, no stranger to off-road events, the Dakar Rally saw the most complex racing car in the brand’s history taking part. All three electrically-powered RS Q e-tron rallycars completed the event to usher in a new era in off-road rallying. The best-placed crew was Mattias Ekstrom/Emil Bergkvist who finished ninth, with team mates Carlos Sainz/Lucas Cruz and Stephane Peterhansel/Edouard Boulanger finishing 12th and 57th, respectively.In the big trucks category, the Russian truckers have always been favourites. They have collected 18 victories with 6 different drivers since the 21st century began. Each of the 4 men at the wheels of the blue trucks has claimed at least one stage, leaving nothing for the competition. Reigning champion Dmitry Sotnikov defended his title and led the Kamaz team to a 1-2-3-4 finish.

Unlike the World Rally Championship events, the Dakar Rally requires navigation and a number of competitors had difficulties in some stages, losing a lot of time. Mechanical problems were, of course, to be expected in the world’s toughest cross-country race that had around 4,261 kms of competitive stages this year.
Dakar 2022 was the 44th edition of the iconic event, which first took place in January 1978. Until 2007, the event ran from Paris to Dakar on the western side of Africa. But with terrorists causing security issues, the 2008 event had to be cancelled and from 2009, it was run on the western side of South America, while retaining the original name.
The participants, mostly based across the Atlantic, were unhappy with the long distance from Europe and resulting high costs of logistics. This led to the event being moved to Saudi Arabia in 2020.
The 2022 event also had a suspected terrorist attack when, 2 days before the start, a support vehicle belonging to one of the teams had a blast through its floor near a hotel in Jeddah. One of the participants in the event, Frenchman Philippe Boutron, was seriously injured as he was in the vehicle. French security services said they would investigate the incident and at one point, it appeared that the event might be cancelled but the organisers did not stop it.
When Audi’s RS Q e-tron starts in the 2022 Dakar Rally this weekend, it will be an entirely new challenge for the engineers. While Audi Sport is no stranger to tough off-road racing, this event will be with a vehicle that runs on electricity rather than petrol – something they have not done before in off-road competition, especially one in the Saudi Arabian Desert.
“With our drive configuration in the RS Q e-tron, Audi is a pioneer in the Dakar Rally,” said Lukas Folie, a high-voltage battery engineer at Audi Sport. “Defining the challenges for this type of competition was very demanding. There are simply no empirical values in motorsport for such a concept and for this type of endurance competition.”
Designing for unknown requirements
Compared to the Formula E World Championship, which Audi last contested with a battery-electric drive, the standards at the Dakar Rally are different: daily stages of many hundreds of kilometres, the enormous driving resistance in the soft desert sand, plus high outside temperatures and a minimum vehicle weight set by the regulations at 2 tons are extremely tough in motorsport.
“It is not possible with today’s battery technology to realize a purely battery-electric off-road vehicle for the Dakar Rally under these conditions,” said Folie. The engineering team led by Axel Loffler, Chief Designer of the RS Q e-tron, therefore had to define basic benchmarks for the overall concept of the vehicle with electric drive and energy converter without any previous data.
Due to the short project development time, Audi relied on proven cell technology. The capacity of the high-voltage battery is 52 kWh and is therefore sufficient for the maximum expected requirements on each leg of the rally. The weight of the high-voltage battery including the cooling medium is around 370 kgs.
The required energy capacity and performance, as well as control and safety mechanisms, made Audi resort to proven round cells as the basis of the high-voltage battery. The battery system is designed in such a way that the drivers will not feel any difference between a new and a used battery.
Demanding off-road charging
When the drivers depart in full electric drive on the morning of each stage with a fully charged battery pack, a highly complex control system begins. Only a few minutes before the start of the stage do the teams learn any details about the route at all when the roadbooks are handed out. The RS Q e-tron must therefore be prepared for all conditions in terms of distances, speeds, difficulty of the terrain and other factors.
The engineers and electronic technicians have programmed algorithms to keep the State of Charge (the charge level) within defined ranges depending on the energy demand. Energy extraction and battery recharging are always in balance over defined distances. If, for example, a difficult dune passage with high driving resistance requires maximum energy for a short time, the state of charge drops within a controlled range. The reason: the drive power of the engine-generator units on the front and rear axles is limited to a maximum of 288 kW in total under the regulations. However, the energy converter can only provide a maximum charging power of 220 kW.
In extreme cases, therefore, consumption is briefly higher than energy generation. “Something like this is possible for a limited time,” said Folie. “But over a longer distance, it always results in a zero-sum game: We then have to regulate the power consumption down so that the battery’s state of charge remains within a corridor. The absolute amount of energy available on board must be sufficient to cover the day’s leg.”
Energy recovery is an important factor
In order to realize maximum efficiency, the engineers are also relying on a principle that has already been used in the Le Mans sportscars and in Formula E – the RS Q e-tron will recover energy during braking. The MGU units on the front and rear axles can convert the rotational movement of the wheels into electrical energy. The aim is to recuperate the maximum energy.
The power flow in this reverse direction is not subject to the same power limitations as when accelerating. What sounds so simple requires a complex Intelligent Brake System. It combines the hydraulic braking function with the electric regenerative brake.
Efficient on the move
Thanks to this targeted design, the RS Q e-tron has an exceptional position in the starting field. This applies not only to the basic system topology of all assemblies, but also to the energy control system. Although it has to move a larger mass due to the regulations, the RS Q e-tron manages with less energy than the competition. The smaller tank volume for the energy converter specified in the regulations proves that the rally car with the four rings is very efficient.
The RS Q e-tron will contest its first Dakar Rally with 3 cars entered by Team Audi Sport, with support from Q Motorsport. The 2022 event, which is the third Dakar Rally in Saudi Arabia, has 12 stages with daily distances of more than 800 kms in some cases. The total length of the rally is 8,099 kms, with 4,252 kms of timed off-road stages.
The 2022 Dakar Rally will start on the second day of January and finish on January 14. It will be run entirely on Saudi Arabian soil, as in the previous two editions. The route will go south, passing through Riyadh, and conclude back in Jeddah. There will be 12 gruelling stages, with navigation, sand and dunes featuring more heavily than in previous editions. 80% of the route will be totally new to competitors. Managing the mechanics and physical exertion are two of the most important aspects of the event, and these aspects are never as decisive as they are during a marathon stage, where the ability to be autonomous is essential, even for those used to helping each other out. In the Empty Quarter, the two marathon days will be run ‘the old-fashioned way’.
Until the Quattro came along in the early 1980s, Audi was known for its front-wheel drive (FWD) cars and showed no interest in rear-wheel drive (RWD). With the quattro system, the company didn’t have to discuss the merits of FWD or RWD; it powered the wheels at both ends of the car. The quattro system has been synonymous with Audi, an exclusive feature on its high performance models.
But the company has not refused to make RWD cars, except that they have been in small numbers and used in competition. Models like the Le Mans-winning cars with hybrid powertrains have had what is essentially RWD, along with the R8 LMS GT4 used by customer racing teams. There has also been the R8 RWS which was a limited-production run of 999 units and ‘made for purists’.
Now, Audi Sport GmbH (which is the company that makes the R8) has come out with a new R8 Performance RWD as a complement to the V10 performance quattro version. It has the same mid-mounted V10 5.2-litre FSI engine with enhanced output of 570 ps/550 Nm to take the car from 0 to 100 km/h in a claimed 3.7 seconds, with a top speed of 329 km/h. Available in Coupe and Spyder bodystyles, it replaces the previous R8 V10 RWD which had served as an entry-level version.
Balanced for rear-wheel drive
The suspension and driving dynamics are specifically balanced for the rear-wheel drive. A mechanical limited slip differential distributes the torque ideally based on the driving situation, ensuring maximum possible traction even when the roads are wet. When Sport Mode is activated in the Electronic Stabilization Control system, the suspension set-up and control systems will allow controlled drifts.
The electromechanical power steering provides has Dynamic Steering, available for the first time for the RWD R8. This provides even more precise reaction and feedback with more direct steering. At the same time, it also increases comfort by making steering easier, such as when parking or manoeuvring.
The RWD suspension, with double wishbones and a passive differential lock, is adapted specifically for rear-wheel drive. The weight distribution is 40:60 and extra-light 19-inch and 20-inch aluminium cast wheels are fitted, or optional Cup wheels in 245/30 R20 up front and 305/30 R20 at the back can be specified. An 18-inch high-performance steel braking system with a wave design and an optional 19-inch high-performance ceramic braking system provide the necessary deceleration.
As with all R8s, the body is built of aluminium using the Audi Space Frame (ASF) design which has been around since the mid-1990s. The structure has evolved over the years and large parts are now made of carbonfibre reinforced plastic for more lightening. The Coupe version thus weighs a mere 1,590 kgs, with the Spyder weighing another 105 kgs more.
Recognizable design features
The overly sporty design is inspired by its GT4 siblings and elements of this include the broad, flat Singleframe radiator grill in matte black with an R8 emblem. There are also the large air intakes, front splitter and rear air outlet grid as well as the oval tailpipes. Enthusiasts will note that the slit under the front bonnet is reminiscent of the legendary Audi Sport quattro.
Racing car cabin
Given the exterior appearance, it would only be expected that the interior will have a ‘racing car feel’ and Audi’s designers have provided that. The eye-catching element inside is the ‘Monoposto’ – the large, heavily contoured arch that spans the area in front of the driver’s seat and is strongly reminiscent of a racing car cockpit. The Monoposto encloses the Audi virtual cockpit with a 12.3-inch screen, which is integrated into a freestanding casing. The R8 leather steering wheel with Multifunction plus has 4 control satellites, each for using Audi drive select, to start the engine, to activate Performance Mode and the engine sound as well as to control the Audi virtual cockpit.
Production largely by hand
The R8 V10 performance RWD is built – largely by hand – at Audi Sport’s factory. This is also the production site of the LMS GT4 racing car, which is derived from the production model and uses roughly 60% carryover parts. In Germany, the base price for the Coupe is €149,000 (about RM717,000), with the Spyder costing another 13,000 euros (about RM63,000).
At the very beginning of 2022, the Dakar Rally will be on again in Saudi Arabia. Among the participating teams will be Audi Sport which was a pioneer in the World Rally Championship with the quattro all-wheel drive in a rallycar. This time, it wants to be the first car manufacturer to use an electrified drivetrain to compete for overall victory against conventionally-powered competitors in the world’s toughest rally.
“The quattro was a game-changer for the World Rally Championship. Audi was the first brand to win the Le Mans 24 Hours with an electrified drivetrain. Now, we want to usher in a new era at the Dakar Rally, while testing and further developing our e-tron technology under extreme conditions,” said Julius Seebach, MD of Audi Sport which is responsible for motorsport at Audi.
Testing and preparation are underway with the new RS Q e-tron which has an all-electric drivetrain. The front and rear axles are both fitted with a motor-generator unit (MGU) from the current Audi e-tron FE07 Formula E car which has been developed by Audi Sport for the 2021 season. Only minor modifications had to be made to use the MGU in the Dakar Rally.
The characteristics of the Dakar Rally present the engineers with special challenges. The marathon event lasts 2 weeks and the daily stages are up to 800 kms in length. “That’s a very long distance,” said Andreas Roos who is responsible for the Dakar project at Audi Sport. “What we are trying to do has never been done before. This is the ultimate challenge for an electric drivetrain.”
Because there are no charging opportunities in the desert, Audi has chosen an innovative charging concept. On board of the car is the highly efficient TFSI engine from the DTM. It is part of an energy-converter that charges the high-voltage battery while driving. Since the combustion engine is operated in the particularly efficient range of between 4,500 and 6,000 rpm, the specific consumption is well below 200 grams per kWh.
A third MGU, of identical design, is part of the energy converter and serves to recharge the high-voltage battery while driving. In addition, energy is recuperated during braking. The battery weighs about 370 kgs and has a capacity of around 50 kWh.
The maximum system power of the e-drivetrain is 500 kW. How much of this may be used during the Dakar Rally is still being finalized by the organizers. The electric drivetrain offers many advantages. The electric motors can be controlled extremely precisely and can thus ensure good drivability. In addition, braking energy can be recovered.
The RS Q e-tron only needs one forward gear. The front and rear axles are not mechanically connected, as is also common in electric vehicles. The software developed by Audi takes over the torque distribution between the axles and thus creates a virtual and freely configurable centre differential, which has the positive side effect of being able to save the weight and space that would have been required by propshafts and a mechanical differential.
“As engineers, we basically see development potential in every component. But in terms of the drivetrain system, we have already achieved a system efficiency of over 97% in Formula E. There’s not much more room for improvement,” revealed Stefan Dreyer, Head of Development at Audi Sport for motorsport projects.
“The situation is quite different with the battery and energy management. This is where the greatest development potential lies in electromobility in general. What we learn from the extremely challenging Dakar project will flow into future production models. As always, we are also working closely with our colleagues from road car development on this project,” he added.
The Dakar Rally entry is being run in conjunction with Q Motorsport. “Audi has always chosen new and bold paths in racing, but I think this is one of the most complex cars that I have ever seen,” said team principal Sven Quandt. “The electric drivetrain means that a lot of different systems have to communicate with each other. Besides reliability, which is paramount in the Dakar Rally, that’s our biggest challenge in the coming months.”
Quandt compares Audi’s Dakar project to the first moon landing. “Back then, the engineers didn’t really know what was coming. It’s similar with us. If we finish the first Dakar event, that’s already a success!” he said.
The prototype of the RS Q e-tron had its first roll-out in the plant only at the beginning of this month. An intensive test program and the first test entries at cross-country rallies are on the agenda from now until the end of the year. “This project’s schedule is extremely packed and challenging,” said Roos. “Less than 12 months have passed since the project officially started. We had to begin the development while the regulations for alternatively-powered vehicles had not even been finalized yet. And all of the development took place during the coronavirus pandemic. You mustn’t underestimate that either. What the team has achieved so far is unique. The roll-out was a very special moment for everyone.”
