Jaguar Vision Gran Turismo SV endurance racing car!

A top speed of 410 km / h, an aerodynamically perfect design and an electric drive train with a high potential for winning - that is the Jaguar Vision Gran Turismo SV, the latest all-electric and virtual racing car from Jaguar. Developed in the real world as a 1: 1 design study for use on the Sony PlayStation. The new model builds on the first electric Jaguar sports car study for Gran Turismo presented in October 2019 - the Jaguar Vision Gran Turismo Coupé. This virtual racer has already proven to be very successful and delights console gamers with its radical design, inspired by the historic Jaguar, the interior that is focused on the driver and the extraordinary handling. Now a team from Jaguar Design, Jaguar SV and Jaguar Racing have gone one better with the Vision GT SV. The aim was, based on the Vision Gran Turismo Coupé, to re-examine everything that could further increase performance and to rethink what an electric Jaguar endurance racing car of the future could look like.

Jaguar Vision Gran Turismo SV:

A detailed analysis of the feedback from console players via online videos or forums proved to be fundamental in this process. These worldwide comments, combined with many hours of their own “behind the wheel”, helped Jaguar's design and engineering teams decide how to develop the Vision GT SV into the truly ultimate electric console endurance racing car. Julian Thomson, Design Director, Jaguar, says: “Jaguar models developed for the racetrack and for road traffic have always shared the same DNA - be it the D-Type and the XKSS or the I-PACE and the I-TYPE. When the design team behind the Vision GT Coupé was commissioned to create the ultimate electric endurance racing car for Gran Turismo, they sat down with colleagues from SV and Jaguar Racing. To create something very special together.

Vision GT SV is a dramatic and visually captivating car. It shows what is possible when the traditional boundaries of real world car design are completely removed. By bringing this car to life in the form of a 1: 1 design study, we were able to present the most extreme interpretation of an electric Jaguar racing car yet. Inspired by the past, but fearlessly looking to the future. ”Designed as the ultimate virtual endurance racer, the Jaguar Vision GT SV pays tribute to its glorious predecessors. The graphic design of the outer skin takes up the motif of an electronic circuit board - to document that the car is powered purely electrically. It is supplemented by dates that refer to the first Le Mans outings of the C-Type and D-Type in 1951 and 1954.

In contrast to the Coupé, the streamlined and lightweight body made of composite material now has four electric motors instead of three. Together they develop an output of 1.400 kW (1.903 hp) and a torque of 3.360 Nm, which is available from the first meter. With the help of all-wheel drive and torque vectoring, the sprint from 0 to 100 km / h takes 1,7 seconds; the maximum speed is 410 km / h. The task of creating an even more exciting racing experience for console gamers with the Gran Turismo SV was the responsibility of the Jaguar SV engineering team.

Jamel Hameedi, Head of Engineering, Jaguar SV, says: “We were given a brief: Take everything that made the Jaguar Vision GT Coupé so special - the performance, the handling and the soundtrack - and take it all to an even higher level. The team not only achieved this goal, they actually exceeded it. The result was a virtual electric racing car that could actually successfully take part in an extreme 24-hour race. The nice thing about it: What the team members saw in the virtual world, they were able to bring into reality with the construction of the exciting 1: 1 model. Certainly to the great delight of the console gamers, who now know what to expect on Gran Turismo in the near future. "

The elegant silhouette of the Vision GT Coupé can still be clearly seen on the GT SV; including the C- and D-type inspired fenders. Despite the additional electric motor on the front axle, the wheelbase remains the same at 2.721 millimeters. At 5.540 millimeters, the GT SV is, however, 861 millimeters longer than the Coupé - a deviation entirely due to the aerodynamics. In order to generate the higher contact pressure required for higher traction in fast corners and maximum directional stability on long straights, the GT SV has a new front splitter and a new and partly "active" rear spoiler. To solve the well-known conflict of objectives between increased contact pressure and reduced air resistance, the SV team worked with the Jaguar designers to develop a whole range of features that, in combination, improve dynamics, stability, performance and efficiency.

In addition to the larger and more efficient splitter - it produces more contact pressure on the front axle - openings in the front bumper direct the air over the front wheels in such a way that turbulence is reduced and the air is directed cleanly towards the rear of the vehicle. The air flowing backwards through the wheel arches is also smoothed out via outlet openings in the fenders. The completely covered underbody - including a keel-like element behind the front axle to optimize directional stability at high speeds - accelerates the airflow, reduces its pressure and thus helps to reduce lift before it finally exits via a large rear diffuser.

The most aerodynamically efficient feature of the GT SV, however, is the “active” rear spoiler, which is inspired by legendary Jaguar sports prototypes such as the XJR-14 from the 1991 World Cup season. The fixed main profile of the wing leads around the corners of the GT SV and then seamlessly merges into the rear hips. The wing is designed as an integral element of the body and fulfills the aerodynamic performance expected of an endurance racing car. Two movable sections automatically swivel upwards at higher speeds to generate additional contact pressure. They return to their normal starting position when minimal air resistance is required.

As a result, the Jaguar Vision GT SV has a drag coefficient of 0,398, which is low for a racing car. At the same time, it produces 320 kg of contact pressure at 483 km / h. Michael O'Regan, Senior Engineer, Aerodynamics, Jaguar SV, says: “All aerodynamic elements have been meticulously optimized using CFD (numerical fluid mechanics) analyzes - in exactly the same way as with real racing cars such as the Formula E Jaguar I. -TYPE. I am particularly proud of how we managed, despite the short time available, to bring the GT SV to the same level as current endurance racing cars in terms of aerodynamic performance. "

Electrifying performance

Jaguar Racing engineers are responsible for the electric drivetrain and its four motors. They were also responsible for the system of the first Jaguar Vision GT, into which they incorporated all of their knowledge and experience from six years of racing with the Jaguar I-TYPE. Two innovations deserve special mention: A second motor for the front axle, which with 300 kW (407 PS) only enables the PS and torque values ​​specified in the specifications. And a thermal management system that has been optimized in view of the increased performance. This is essential in order to keep the high speeds and extreme acceleration processes occurring in a long-distance race under thermal control over the entire distance.

With one motor per wheel, the drive system of the GT SV has an output of 1.400 kW (1.903 hp) with a maximum torque of 3.360 Nm. Each motor has its own single-stage gearbox - strong and robust enough to withstand the extreme torque peaks. Minimal unsprung masses and friction ensure maximum efficiency and all together the problem-free achievement of the top speed of 410 km / h. In addition to all-wheel drive, the “one motor per wheel” configuration also allows unlimited control of the lateral and longitudinal distribution of torque: a quantum leap in terms of torque vectoring for even more traction, agility and stability.

The motors get their driving power from a state-of-the-art lithium-ion battery pack. Installed close to the center of gravity, it guarantees a low roll center (rotation around the longitudinal axis) and an almost perfect weight distribution. James Barclay, Team Director, Jaguar Racing, says: “The parallel work on the Jaguar I-TYPE Formula E models and the Vision Gran Turismo SV gave Jaguar Racing engineers the unexpected opportunity to share their expertise in two incredible electric racing cars to let: our most advanced Formula E to date and a Jaguar endurance racing car for the virtual world.

Both were designed and developed using state-of-the-art simulation tools to push the electric drive train and software technology to new limits. We can hardly wait to see how the two models fare in season 7 of the ABB FIA Formula E and Gran Turismo. ”The thermal management system of the Vision GT SV is adapted to the increased performance via an additional cooling circuit made of liquid nitrogen. The extra cooling capacity allows the battery to deliver full power over a longer period of time and at the same time to remain within a healthy temperature window. The nitrogen cooling is connected to a boost button. Pressing the button ensures that the battery never exceeds its upper temperature limit, even under the toughest racing conditions.

The ultimate virtual driving experience

Jaguar has further refined the soundtrack for the GT SV, which amplifies the unique driving experience in the Vision GT Coupé. It is now even more distinctive and determined to reflect the further increased performance thanks to the fourth electric motor. The soundscape sounds futuristic on the one hand, and authentic Jaguar-like on the other. The crescendo culminates in a maximum speed of 40.000 rpm - evidence of true racing DNA and evidence of unrivaled driving pleasure.

Last but not least, the tailor-made cockpit for racing also contributes to the inimitable driving experience. The puristic, curved surfaces envelop the driver and both the instruments and all the controls are exactly where they should be. Each part is beautifully and with absolute precision made from modern lightweight materials, including the new TYPEFIBRE fabric with which the two seats made of composite material are covered. TYPEFIBRE is a performance material developed by Jaguar as a lighter alternative to leather; it is characterized by its high level of comfort and durability. Jaguar Racing is testing TYPEFIBRE on the seats of the two I-TYPE 5s with which Sam Bird and Mitch Evans will enter the seventh season of the ABB FIA Formula E World Championship from January 2021.
