Since making its entry in 2015, Viper Niza Racing has been among the more successful fully Malaysian racing teams in regional and international competition. Its most significant victory was the class win at the 2019 TCR SPA500 24-Hour endurance race in Belgium with a CUPRA Leon.
Now, after 105 race starts by its driver and Team Principal & Owner, Douglas Khoo, Viper Niza Racing is taking a big step forward with two new racing cars for an assault in international and regional GT sportscar racing.
KTM, the Austrian company (with India’s Bajaj Auto as a shareholder), is well known for its motorcycles but it also has a line of 4-wheelers that have been in production since 2008. Known as the X-BOW, the sportscar was developed in collaboration with Dallara, Kiska Design and Audi.
The X-BOW was developed with motorsports in mind (it is FIA-homologated) and has seen good demand that the company raised the annual production plan from 500 units to 1,000 units. Since entering the market 14 years ago, the model has been improved with upgrades to the TFSI engine provided by Audi.
Even before the Emira is ready for delivery to customers, Lotus has been developing the model as an all-new competition-spec GT4 challenger. While it will be the last model from the British carmaker that will use a combustion engine, it also marks the start of a new era in performance GT racing for Lotus.
The race-ready concept follows the July launch of the Emira and its dynamic debut at Goodwood Festival of Speed and is developed in collaboration with project partner RML Group. Like almost all modern Lotus road cars, each customer car will be a homologated performance machine, hand-built with lightweight motorsport components and equipment to meet the latest safety regulations.
The development team has focused on precision engineering to deliver outstanding dynamics and high-speed stability. The advanced composite bodywork makes the car exceptionally lightweight and, coupled with Toyota’s race-proven engine and optimized GT4 aerodynamics derived from the road-going Emira’s advanced exterior design.
Limited number for 2022 season
The Emira GT4 will be officially launched later this year and only a limited number will be built in time for the 2022 season. Additional cars will be built for 2023 in line with global demand.
“The all-new Emira GT4 is an exciting next step following the hugely successful launch of the Emira road car. We have worked hard with the team at RML Group to ensure this next-generation of Lotus GT car will deliver race-winning performance,” said Richard Selwin, Race Programme Manager at Lotus.
Lotus Sports Car Architecture
The Emira has been developed on a new lightweight bonded aluminium chassis, technology pioneered by Lotus, and which remains part of the company’s sportscar DNA. Known as Lotus Sports Car Architecture, it debuted with the Elise. However, for the Emira, every dimension is different to any previous Lotus chassis and it is fabricated in an all-new facility as well.
While the GT4 car will use only familiar Toyota-source, Lotus-engineered supercharged 3.5-litre V6, customers who buy the 72,000 euro (about RM354,000) production model will also have a second option of a Mercedes-AMG 2-litre turbocharged unit, the M139. This is currently the world’s most powerful production 4-cylinder unit. Depending on the state of tune done by Lotus engineers, the German engine could provide up to 416 bhp and will come with AMG’s 8-speed dual-clutch transmission.

Jenson Button, former F1 World Champion, has driven the Emira and had this to say: “You always expect a Lotus to have good mechanical grip through the low-speed corners but there was plenty of downforce in the high-speed corners too. That means the feeling of great balance is the same no matter how you’re driving it. It’s exceptional and I’m a big fan. I’m still in shock at the price. Starting at under £60,000, it’s fantastic and means so many people are going to have the opportunity to experience it first-hand. It’s being called a ‘junior supercar’ but it would give a lot of supercars a run for their money… and it’s more comfortable than most of them!”

The return to world motorsport is a key pillar of the company’s transformation. Earlier this year Lotus Engineering, the consultancy division of the business, became technical partner to JBXE, the Extreme E race team led by Button.
Following the launch of the new Mercedes-AMG GT3, Mercedes-AMG has now come out with an updated GT4 model for the tenth anniversary season of its Customer Racing Programme. The new GT4 features new design characteristics and technical optimisations that, among others, enhance the endurance racing performance. Homologation is expected to be completed this month so customers can receive their cars soon.
In the past 2 years, the ‘little brother’ of the GT3 advanced to one of the most successful cars in the booming GT4 segment worldwide. So far, more than 120 units have been delivered to Customer Racing Teams all over the world. With the new edition of the GT4, Mercedes-AMG expects to give the teams even greater competitiveness.
Improved brake and engine cooling
The notable improvements of the new GT4 are in its optimised brake cooling around the front axle as well as enhanced engine cooling. Both the enlarged brake air inlet as well as the dimensionally stable brake air lines with larger diameter prevent the brake components from overheating. As a result, they ensure better driveability as well as considerably reduced wear of the brakes that are under particular load during endurance races.
Thanks to a new carbonfibre brake air duct, adapted heat protection and optimised brake caliper adapters, the airflow through the thermally affected parts has been improved. A newly developed brake disc on the front axle, aimed at reliability and longevity, complements the optimised brake cooling.
The re-arranged oil cooler contributes to an even more effective cooling of the proven AMG 4-litre V8 biturbo engine, just like the new carbon exhaust air duct and the newly shaped edge on the bonnet, made of natural fibre enforced material. As a result, the Mercedes-AMG GT4 can reliably deliver its performance, even in extremely hot conditions.
New light concept
The update of the GT4 also includes optimised front and rear lights, identical to the corresponding GT3’s. Their design is in line with the current Mercedes-AMG GT road cars. Next to the facelifted look, the new light concept also comes with a practical purpose: the new LED high-performance headlights provide considerably better illumination of the track. In darkness or in poor visibility, this can lead to decisive advantages for the drivers in terms of safety and performance.
Optimised handling
Another optimisation are the modified track rods on the rear axle that are also similar to those used on the new GT3 model and that come with a significantly extended longevity. As a result, the that has, among others, already racked up three class wins in the Nurburgring 24-hour race, is even better prepared for endurance races in the toughest conditions. The integration of an enlarged brake fluid tank, optimised with the particular requirements in endurance races in mind, is also one of the changes in the 2020 GT4.
Highest safety standards
Like its road cars, the GT4 has particularly high safety standards relevant to track racing. The roll-cage of high-tensile steel has been bolted to the aluminium spaceframe and a recovery hatch has been integrated into the roof of the car. The carbonfibre driver safety cell with integrated headrest provides a considerably higher level of protection than usual racing seats. A powerful fire extinguishing system complements the comprehensive safety concept.
Stefan Wendl, head of Mercedes-AMG Customer Racing: “When we entered the GT4 segment two years ago, it was our aim to build a car that was capable of winning right away. Looking at the achievements of the Mercedes-AMG GT4, we have succeeded in doing so in an impressive way. In order to enable our Customer Racing Teams to accomplish such top achievements at the race track in the future as well and to be prepared in the best way for the challenges in newly entered markets like Asia and South America, we have now decided to update the Mercedes-AMG GT4.
