Many of today’s electric vehicles (EVs) have a battery pack that can store a considerable amount of energy. The energy is used to power the electric motors that move the vehicle, but the battery packs can also be used as mobile power supply units in areas that have experienced natural disasters.
Nissan is exploring such an idea with the RE-LEAF, a working prototype based on its current LEAF EV. The RE-LEAF can be driven into a disaster zone and provide a fully mobile power supply for machinery or other equipment on-site used by rescue teams.
Electricity for all kinds of devices
Alongside modifications to navigate roads damaged or covered in debris, the RE-LEAF has weatherproof plug sockets mounted directly to the exterior of the vehicle. These can be connected to 110V to 230V devices which can be supplied electricity from the car’s high-capacity lithium-ion battery pack.
The integrated energy management system can run medical, communications, lighting, heating and other life-support equipment.
“We’re constantly exploring ways that electric vehicles can enrich our lives, beyond just zero-emission transportation,” said Helen Perry, Head of Electric Passenger Cars and Infrastructure for Nissan in Europe. “Concepts like the RE-LEAF show the possible application of EVs in disaster management and demonstrate that smarter, cleaner technology can help save lives and provide greater resilience.”
Real-world applications
Nissan developed the RE-LEAF to demonstrate the potential of electric vehicles in disaster recovery. Although it’s just a working concept, the technology is already being used in the real world. In Japan, Nissan has used the LEAF to provide emergency power and transportation following natural disasters since 2011, and the company has formed partnerships with more than 60 local governments to support disaster relief efforts.
Natural disasters are the biggest cause of power outages. A 2019 World Bank report found natural shocks and climate change caused 37% of outages in Europe between 2000 and 2017, and 44% of outages in the U.S. over the same period.
When a disaster hits, the time for electricity supply to be restored is typically 24 to 48 hours, depending on the severity of the damage. During that period, EVs can provide zero-emission mobile emergency power.
Portable power station
Acting as a portable power station, the latest LEAF e+ model with a fully charged 62 kWh battery pack can provide enough electricity to power the average European household for 6 days. As a disaster recovery vehicle, it can power multiple devices simultaneously for a period of up to 24 hours.
Some examples which use 230V power are an electric jackhammer, pressure ventilation fan, 10-litre soup kettle, intensive care medical ventilator, and 100W LED floodlight.
Once electricity is restored to the area, the EVs can then be recharged and provide zero-emission transport – up to 385 kms for the LEAF e+.
Nissan EVs can also act as mobile storage batteries to supply homes and society with electricity during non-emergency situations through Nissan Energy Share, creating a distributable energy model that can be used to help stabilize supply and demand.
“Electric vehicles are emerging as one of the technologies that can improve resilience in the power sector,” Perry said. “By having thousands of EVs available on standby, either as disaster support vehicles or plugged into the network through Vehicle-to-Grid, they’re uniquely capable of creating a virtual power plant to maintain a supply of energy.”
The latest Nissan LEAF EV is available in Malaysia. For more information, visit www.nissan.com.my.
Genesis, Hyundai Motor’s premium brand, has a brand new SUV under final stages of development. It has been announced publicly in Korea so that the R&D guys can start running real-world tests on public roads.
QR code on camouflage
However, the vehicle, designated GV70, is camouflaged as the teaser pictures release show. To use the testing exercise to do a bit of promotion, there’s a QR code on the bodywork which leads those who scan it to a web page that explains the camouflage pattern referred to as ‘G-Matrix’.
G-Matrix is inspired by the diffused reflection of light from precision-cut diamonds and is a core part of the Genesis brand identity. Drivers can look forward to the creative application of the pattern on the GV70 in different ways, emphasizing the details that are emblematic of the Genesis brand.
Second of three SUVs
While specific details are presently hidden by the G-Matrix camouflage pattern, the continued evolution of Genesis’ signature “Athletic Elegance” design language is evident. The new midsize SUV will join the GV80 in the model line-up for 2021, after which will come a smaller model (GV60?).
“We are thrilled to share this early sneak preview of our second SUV, the Genesis GV70,” said a Genesis official. “It telegraphs an exciting new design and reinforces the core brand values that run through our line-up. We look forward to sharing full details on GV70 with everyone in the near future.”
Shared platform likely
Given its size and positioning, the GV70, which will challenge SUVs like the BMW X3 and Audi Q5, is likely to share architecture with the new Hyundai Tucson. It obviously doesn’t make sense for Genesis to have its own platforms, an approach which manufacturers discarded after the 1980s when it proved more and more expensive to develop a platform. The key nowadays is how many models can be derived off a platform with minimal modifications.
With the way electrification of cars is going, there will come a time when electric power replaces combustion power in racing cars. In fact, it’s already started with the Formula E series for single-seaters and the electric version of the TCR.
Manufacturers like Hyundai Motor are preparing for this change and one project that the company’s high-performance N division has revealed its next-generation electrified RM20e Racing Midship Sports Car. ‘RM’ refers to the prototype model’s ‘Racing Midship’ rear-drive, midship powertrain configuration, a fundamental design differentiator that yields ideal handling balance and agility from a low polar-moment of inertia.
“Our new electrified RM20e pushes the proven RM platform forcefully into a new, environmentally-focused decade of the 21st century, stretching the performance envelope of electrification on normal road environments,” said Albert Biermann, President and Head of Research and Development Division at Hyundai Motor Group.
“RM20e represents a revolutionary new chapter of electrified performance for the Racing Midship series, and our N engineers continue to garner valuable insights in the arena of zero-emission performance dynamics,” he declared.
Testing high-performance technologies
The RM platform is an engineering ‘rolling lab’ for testing high performance technologies at all speeds and driving conditions. The testing is especially important to ensure that the RM20e’s copious 596 kW/810 hp and 960 Nm output can be effectively transmitted to the ground on all types of surfaces.
Performance times are expected to be less than 3 seconds from 0 – 100 km/h and less than 10 seconds from 0 – 200 km/h. The positioning of the motor in the middle and the rear-drive layout provides optimal traction required for this level of acceleration. While having racing car-like levels of performance, balance, braking and grip, the engineers have been working to also provide quietness, responsiveness and road-going capability for daily drivers.
Variety of powertrains available
The electrified powertrain has zero-emissions, of course, and as Hyundai has developed a variety of electrified-propulsion solutions. Therefore a full spectrum of electrified powertrains is available for testing with this high-performance sportscar platform.
Hyundai’s recent investment and strategic partnership with Rimac Automobili has facilitated co-development of both BEV (Battery Electric Vehicle) and FCEV (Fuel Cell Electric Vehicle) prototypes. The electrified RM platform will continue to evolve along with the growth of this RIMAC partnership.
44 eco-friendly models by 2025
The Hyundai Motor Group, which includes Kia Motors, has set a strategic plan to deploy 44 eco-friendly models by 2025, which will include products from the N brand as well.
“The RM20e sports car prototype clearly signals future electrified brand aspirations for Hyundai’s performance N brand, moving N into the prestigious genre of supercar-level performance. RM20e proves that N driving excitement will not be compromised, even in electrified model variants.,” said Thomas Schemera, Executive Vice-President and Head of Product Division at the Hyundai Motor Group.”
The history of the RM project goes back some 8 years and has served to develop and connect new high-performance motorsports technologies with future N models. Since the initiation of project RM, there has been a progressive evolution of the RM series with prototypes RM14, RM15, RM16 and RM19. In 2019, Hyundai’s first electric racing car – the Veloster N eTCR (pictured above) – was developed for the eTCR electric touring car series.
The epitome of what driving pleasure is all about – the sportscar – will never go away. In spite of periods when the numbers declined and many carmakers decided that they could not afford the luxury of making such cars, the voices of the enthusiasts around the world (and also within the company) have brought back sportscars.
The Nissan Z is one such example. An icon among sportscars, it was among the first from a Japanese brand and it made a tremendous impact, especially in America where the biggest number has been sold in its 50-year existence.
The Z Car – past and present (top), and the future.
Other than a short break in the early 2000s when Nissan was recovering from financial difficulties, the Z has had a presence in the Nissan range with the generation on sale since 2009 being the sixth one.
Soon a seventh generation will be launched and it will be a totally new design with new technologies, as would be expected after a lapse of some 10 years. Nissan gave an online preview of the model – referred to as the ‘Z Proto’ for now – today from its base in Yokohama, Japan, with a clear promise that ‘the new Z is on its way’.
It wasn’t difficult to understand the excitement and passion of the original Z and earlier generations as many people involved in the project had memories of the sportscar and even owned it, including Nissan CEO Makoto Uchida, who introduced the Z Proto.
Past meets future
The design of the Z Proto was done largely in Japan and while feedback was considered from many markets, Hiroshi Tamura, Chief Product Specialist of the Z Proto, admitted that the comments of the Z community in America were influential simply because it is where the most Zs have been sold.
Given the heritage of the car, it’s only expected that the designers would constantly look back at past generations, especially the very first one, for inspiration and guidance. The long-nose silhouette, in particular, is a must for the Z but the retro theme is also combined with projected futurism.
“Our designers made countless studies and sketches as we researched each generation and what made them a success,” said Alfonso Albaisa, Head of Design at Nissan. “Ultimately, we decided the Z Proto should travel between the decades, including the future.”
Headlight with cover on the original Z (left) and the PROTO Z headlight (right) which mimics the reflections.
The shape of the bonnet and the canted, teardrop-shaped LED headlights are both unmistakable reminders of the original Z. “The LED headlights have two half-circles that hark back to the Japan market-only 240ZG of the 70s,” Albaisa explained. “The ZG had clear dome lenses over the headlight buckets, which under light give off two circular reflections over each headlight. We liked that unique characteristic and discovered that it naturally fit with the Z’s identity.”
The rectangular grille’s dimensions are similar to the current model with the addition of oval grille fins to offer an updated modern look. However, the link to the original Z is most striking when viewing the Z Proto from the side. The roofline flows from the nose to the squared-off rear to create a distinctive first-generation Z profile whose rear edge was slightly lower than the front fender height giving the Z its unique posture. The signature transition from the rear quarter glass to the low-slung position of the rear tail adds to the effect.
The rear takes inspiration from the 300ZX (Z32) taillights, reinterpreted for the modern world. Set within a rectangular black section that runs across the rear and wraps around the outer edges, the LED taillights convey a sharp glow.
Sharp-eyed readers may notice that the badge on the rear says ‘Fairlady Z’ and this could be a bow to the original legendary car. It might also be used for the future domestic model since the name does have a historical connection to the Japanese fans and owners.
Vintage touch, modern feel
The Z Proto’s cabin blends modern technology with vintage Z touches. The interior design team sought advice from professional motorsports legends to create an ideal sportscar cabin, both for road and track.
This can be seen in the Z’s instrumentation, a 12.3-inch digital display with all the information the driver needs to have. The tachometer is the dominant item with a digital speedometer and vital information is arranged to help the driver grasp it at a glance, such as the redline shift point at the 12 o’clock position.
It’s difficult to replicate the original steering wheel of the Z due to safety requirements but the designers have still tried to keep some vintage aesthetic. It is deeply dished and the driver has quick access to controls with switches on the left and right spokes.
Although digital display screens can be designed to provide the driver with all kinds of information and free up space on the dashboard, the designers have still retained that old-school sportscar look with three small round meters placed on top of the dashboard. In the Z Proto, these show boost pressure, turbocharger rpm and voltage although the ones in the production car might show other information.
Yellow accents are found throughout the cabin, including stitching on the instrument panel. The seats feature special yellow accenting and a layered gradation stripe in the centre of the seats to create depth. Incidentally, the bright yellow pearlescent paint of the exterior is a tribute to a popular paint scheme on both the first generation Z and the 300ZX (Z32).
6-speed manual gearbox lives on
Although the Z is about more than power increases, each new generation has nevertheless had a more powerful engine and the new Z can be expected to continue to provide punchy performance. “Z is a balance of power and agility,” said Tamura. “It is a vehicle that creates a connection with the driver not just on the physical level, but emotionally, and responds to the driver’s impulses.”
For this reason, Nissan will continue to offer a 6-speed manual gearbox. There’s usually not much to say about a manual transmission, unlike automatic transmissions which have constantly improved with advancements in electronic control technologies.
However, 12 years ago, Nissan did draw a lot of attention to its manual transmission in the new 370Z which had the world’s first synchronized downshift rev-matching system. Known as SynchroRev Match, the system blips the throttle just prior to downshifts and upshifts to match engine speed to the next gear. The result is a smoother transition which used to be only possible by drivers who knew about ‘heel-and-toe’. This feature should still appear in the new Z.
Will it be called ‘400Z’?
50 years ago, Yutaka Katayama – regarded as the ‘father of the Datsun Z’ – bravely removed the ‘Fairlady’ badges on the cars that arrived in America. The man in charge of Nissan’s subsidiary in America understood that ‘Fairlady’ (which was the chosen by Nissan’s President after he saw ‘My Fair Lady’, the play) was just not right for such a sportscar. So he chose something from the internal coding (Z432) and used just ‘Z’ to designate the new car. Which worked superbly and started a legendary line of sportscars.
The new Z will have the model code ‘Z35’ to follow the sequence that began in 1984 with the 300ZX. Rumours are that it will be badged ‘400Z’. Nissan does have a version of the VQ engine with a 4-litre displacement but this is designed for SUV applications so the ‘400Z’ would likely have an updated 3.7-litre unit as Nissan confirms it will be an ‘enhanced V6 twin-turbocharged engine’. Production is set to start next year so it would probably be in showrooms sometime in the second half of 2021.
Nissan has been taking a beating in recent times, with its CEO being charged with financial wrongdoing and massive losses worsened by the COVID-19 pandemic. It’s getting to be like the 1990s when a steady decline in its business saw a debt of US$20 billion by 1999 putting it on the brink of bankruptcy.
The new management team is struggling to slash expenses worldwide, cutting at least 12,500 jobs globally by March 2023 and closing some factories. It’s almost like the early years of the Ghosn era when his ‘Nissan Revival Plan’ called for 5 factories to close with a termination of up to 21,000 jobs and 50% reduction in suppliers. Though criticised for his extreme measures, Ghosn turned Nissan around completely by March 2001 with a net profit of 331.1 billion yen.
Product development was naturally hampered by limited budgets; reduced sales could not generate enough revenue to effectively fund development of the next generations. But Ghosn kept morale high with the revival of the GT-R and also authorised continuation of the legendary Z sportscar, the former still a significant model 13 years after its launch.
Now, Nissan is doing the same thing with what looks like a new Z, and the prototype will be revealed to the world on September 15, 2020 at 7:30 pm in America (8:30 am on September 16 in Malaysia). The prototype could be the final form for the new sportscar which is rumoured to be designated ‘400Z’.
Typically, Japanese manufacturers show off a ‘prototype’ which is pretty much production-ready and then launch the new model within the next 12 months. If it was not something about to go into production, they would more likely call it a ‘concept car’.
Actually, Nissan already hinted at a new Z in May and a teaser video showed the silhouette of a sportscar (above). It had the characteristic long nose and as for what will be under the bonnet, probably a V6 from the current engine family that has won awards for years and years.
Remember the date: September 16 at 8:30 am in Malaysia.
Three years after being shown to the world for the first time, the development of the Mercedes-AMG Project ONE hypercar is entering a new phase as several pre-production models are now clocking fast laps at the company’s own proving ground and technology centre. Testing is now largely transferred from the test stands to concentrate more and more on actual running.
For the first time, the project leaders have also authorised testing of the comprehensively electrified and highly complex hybrid power unit with its full output of more than 1000 hp. The objective of reaching a new dimension of driving dynamics and performance for a road-going vehicle with the Project ONE and thereby setting a new milestone in automotive history is thus gradually drawing closer for Mercedes-AMG.
Along with the dynamic test programme and some refinements to the car’s driveability, development work is also focused on its active aerodynamics. The complex interplay between the various active components such as the louvres, the air outlets in the front fenders or the large rear aerofoil is now confirming its effectiveness even outside the wind tunnel as a means of delivering the car’s exceptional lateral dynamics.
Making the Project ONE road-legal
The adaptation of a complete Formula 1 drive unit for a road-legal hypercar must also deliver perfectly in terms of everyday performance and be able to drive in all-electric mode, This represented a tremendous challenge; as far as many aspects were concerned, such as noise level, the development team ventured into uncharted territory with this project and had to find solutions that could be developed for production cars.
In parallel to the extensive dynamic testing being undertaken with the project vehicles, the attendant development work also continues. The various vehicle systems are put meticulously through their paces on the engine test beds and in the in-house simulator. The next step in this extensive programme of testing and development – testing on the north loop of the Nurburgring.
All 275 units – each priced from 2.28 million euros (around RM11.38 million) – that will be made already have customers waiting and the first one will get their hypercars sometimes in 2021 (originally 2019).
Even before the all-electric Ford Mustang Mach-E reaches its first customers in America at the end of this year, the carmaker has come out with a ‘special’ to show off its performance. The one-off Mustang is called the Mach-E 1400 and where, in the old days, the ‘1400’ might have referred to the engine size, in this case it refers to the output of 1,400 horsepower.
The prototype can generate that much power with 7 electric motors and not a drop of petrol is needed. The chassis and powertrain work together for a multitude of track set-ups offering capability unlike any other vehicle.
“Now is the perfect time to leverage electric technology, learn from it, and apply it to our line-up,” said Ron Heiser, Chief Program Engineer for the Mustang Mach-E. “Mustang Mach-E is going to be fun to drive, just like every other Mustang before it, but Mustang Mach-E 1400 is completely insane, thanks to the efforts of Ford Performance and RTR.”
The Mustang Mach-E 1400 is the result of 10,000 hours of collaboration by Ford Performance and RTR aimed at bridging the gap between what an electric vehicle can do and what customers tend to believe it can do.
“Getting behind the wheel of this car has completely changed my perspective on what power and torque can be,” said Vaughn Gittin Jr., RTR Vehicles founder, motorsports champion and professional fun-haver. “This experience is like nothing you’ve ever imagined, except for maybe a magnetic roller-coaster.”
The Mustang Mach-E 1400 has taken shape without rules. The Ford design team and RTR used many of the same tools Ford uses for its racing cars and production programs. Aerodynamics are optimized for shape and location, with a focus on cooling ducts, front splitter, dive planes and rear wing.
There are 5 extra electric motors compared to the Mustang Mach-E GT. Three are attached to the front differential and four are attached to the rear in pancake style, with a single driveshaft connecting them to the differentials, which have a huge range of adjustability to set the car up for everything from drifting to high-speed track racing.
“The challenge was controlling the extreme levels of power provided by the 7 motors,” said Mark Rushbrook, Motorsports Director, Ford Performance. “Mustang Mach-E 1400 is a showcase of the art of the possible with an electric vehicle.”
The chassis and powertrain are set up to allow the team to investigate different layouts and their effects on energy consumption and performance, including rear-wheel drive, all-wheel drive and front-wheel drive.
Drift and track setups have completely different front end configurations like control arms and steering changes to allow for extreme steering angles in drifting. Power delivery can be split evenly between front and rear, or completely to one or the other. Downforce is targeted at more than 1,045 kgs at almost 260 km/h.
The 56.8-kWh battery pack contains nickel manganese cobalt pouch cells for ultra-high performance and a high discharge rate. The battery system is designed to be cooled during charging using a di-electric coolant, decreasing the time needed between runs.
An electronic brake booster is integrated to allow series regenerative braking combined with ABS and stability control to optimize the braking system. The Mustang Mach-E 1400 is fitted with Brembo brakes, like the Mustang GT4 racing car, and a hydraulic handbrake system designed for drifting that integrates with the powertrain controls to enable the ability to shut off power to the rear motors.
It is set to debut at a NASCAR race soon and will serve as a test bed for new materials. The bonnet is made of organic composite fibres, a lightweight alternative to the carbonfibre that is used on the rest of the bodywork.
The Ford Mustang is officially sold in Malaysia with full aftersales support and warranty. Visit www.sdacford.com.my to know more.
Electric powertrains used to have a poor image, considered suitable only for buggies around golf courses. That was when the technology was still in its infancy (though electrically-powered cars were already on roads in the 1930s) and performance as well as range were poor.
But since the beginning of the 21st century, R&D for electric vehicles (EVs) has accelerated, partly prompted by increasingly strict emission regulations that make it very hard for the internal combustion engine (ICE) to meet. Many of today’s EVs operate with performance levels that are comparable to ICE cars and will continue to advance as they enter the mainstream.
As has happened almost since the beginning of the automobile, extending performance is a challenge for the engineers and the same is happening in the EV field. Here’s the latest example: the Mustang Cobra Jet 1400 by Ford Performance.
This is a one-off project to create a factory drag racer with all-electric propulsion. It’s projected to cross the quarter-mile (about 400 metres) in the low 8 second range at more than 270 km/h.
The powertrain is a prototype purpose-built and projected to deliver over 1,400 ps, with over 1,491 Nm of instant torque to demonstrate the capabilities of an electric powertrain in one of the most demanding race environments.
“Ford has always used motorsport to demonstrate innovation,” said Dave Pericak, Global Director, Ford Icons. “Electric powertrains give us a completely new kind of performance and the all-electric Cobra Jet 1400 is one example of pushing new technology to the absolute limit. We’re excited to showcase what’s possible in an exciting year when we also have the all-electric Mustang Mach-E joining the Mustang family.”
Uner the bonnet
Following the debut of the all-electric Ford Mustang Mach-E SUV – the first-ever, all-electric Mustang – the Mustang Cobra Jet 1400 prototype represents another opportunity to advance the Mustang’s heritage and performance while simultaneously incorporating some of the most advanced technology coming to Ford’s future powertrains.
The name used for the prototype also honours the original Cobra Jet that first dominated dragstrips in the late 1960s and still is a major force in sportsman drag racing today. Ford Performance continues to test the Cobra Jet 1400 ahead of its world debut later this year at a drag racing event.
“This project was a challenge for all of us at Ford Performance, but a challenge we loved jumping into,” said Mark Rushbrook, Global Director, Ford Performance Motorsports. “We saw the Cobra Jet 1400 project as an opportunity to start developing electric powertrains in a race car package that we already had a lot of experience with, so we had performance benchmarks we wanted to match and beat right now. This has been a fantastic project to work on, and we hope the first of many coming from our team at Ford Performance Motorsports.”
When digital graphic displays were available for use in cars, they were inserted in the dashboard, usually in the middle section. Before long, interior designers began to bring the display ‘out’, giving it the form of a tablet like an iPad slotted onto the dashboard. Perhaps this made installation easier and users would also have appreciated the familiar tablet shape.
However, Nissan designers who work on next-generation vehicles consider other aspects as they attempt to balance design, technology and utility. For the Ariya Concept, they chose a different path when developing the display.
This prioritized design and vision over the latest trends. Instead of a tablet, the all-electric crossover has a curved, two-screen display reminiscent of a wave. It adds to the sense of a ‘horizon’ throughout the car, from elements in the door all the way to the rear of the cabin.
The layout reflects Nissan’s new ‘Timeless Japanese Futurism’ design language, also expressed in the Ariya Concept’s unique frontal ‘shield’. But the horizontal design wasn’t chosen for its good looks alone. In addition to conveying information better for the human eye, the layout does so from a safer location — in the line of sight, closer to the road.
By matching the cabin’s horizon aesthetic, it becomes a seamless part of the dashboard. Nissan’s design team calls this engawa – the undefined space between where you are, and where you are going.
“The human eye naturally looks from side to side when driving,” explained Tomomichi Uekuri, Senior Manager of the engineering team involved in HMI (Human-Machine Interface). “People can see and absorb more information if it’s laid out horizontally. Peripheral vision works this way as well.”
The Ariya Concept’s display keeps driving information in an instrument cluster location similar to that of a traditional car, while displaying entertainment information, comfort controls and system status in the centre screen. Both are wrapped together in a sleek panel that flows seamlessly between driver and passenger.
Even though there are two screens, information can move or be swiped between them to create the feeling of a single display. For example, if you want your route directions and map in front of the steering wheel, they can appear there. They can also move to the centre, or disappear when no longer needed.
“The display’s wave construction is innovative and utilizes an ergonomic layout for both the meter display and the centre display, not only for visibility, but also allows the driver to easily reach the touch screen,” Uekuri said.
It took the design team many tries to arrive at the innovative display. The team built similar displays into a large black ‘box’ that they affectionately named ‘the Monolith’, a nod to the movie ‘2001: A Space Odyssey’. They chipped away, figuratively speaking, at the housing until it became what’s seen in the final concept car.
As a result, the sleek, seamless display looks like a natural, integrated part of the interior design – not a slab out of time and place.
Ever since the pneumatic tyre was invented, motorists have had to live with the possibility of the air inside leaking out due to being punctured by a nail or damage from hitting a pothole. Loss of air pressure, which is what keeps the tyre in its hard shape to roll along, means the tyre cannot be used and has to be replaced. Not something you want when you are on the way to a meeting or a holiday resort.
Various solutions have been developed over the years which try to keep the tyre usable even when the air is gone. Run-flat tyres are capable of continuing even when deflated, though at limited speeds and for a limited distance. Obviously, they need to be replaced or repaired as soon as possible.
More specialised tyres for off-road use have flexible foam inside which can maintain the tyre shape even when air has leaked out.
Regenerating the tread
Now Goodyear is taking another approach with a prototype tyre it calls recharge. This is reloadable and has a tread compound that can be recharged with individual capsules, radically simplifying the process of replacing your tyres.
Filled with a customized liquid compound, these capsules allow the tread to regenerate and the tyre to adapt over time to climatic circumstances, road conditions, or simply how you want to travel. Thanks to artificial intelligence, a driver profile would be created around which the liquid compound would be customized, generating a compound blend tailored to each individual.
The compound itself would be made from a biological material and would be reinforced with fibres inspired by one of the toughest natural materials in the world – spider silk. This would make it both extremely durable and 100% biodegradable.
No maintenance needed
In addition to radically simplifying the process of replacing tyres using the rechargeable capsules, the tread would be supported by a lightweight, non-pneumatic frame and tall-and-narrow shape. This is a thin, robust low-maintenance construction that would eliminate the need for pressure maintenance or downtime related to punctures.
“Goodyear wants the tyre to be an even more powerful contributor to answering consumers’ specific mobility needs,” said Mike Rytokoski, Vice-President and Chief Marketing Officer, Goodyear Europe, “It was with that ambition that we set out to create a concept tyre primed for the future of personalized and convenient electric mobility.”
Recharge is just a concept for now although it could become one of the features of tyres of the future. Only thing is, if the tread can be regenerated, then the tyres doesn’t need to be replaced. That’s good for the environment but is it going to be good for company business?
