MURRAY TO RELEASE A SIZE 50 MORE POWERFUL AND EVEN LIGHTER RACE
The Racing version generates more than 1500 kg of downforce – 170% more than its weight
Even lighter – the Racing T.50 weighs only 890 kg
Even more powerful – the race-tuned Cosworth V12 delivers over 700 hp; Ram-induction pushes the output beyond 730PS
Murray: “We’ve changed hundreds of parts to optimize the car for racing and track use”
Road-spec T.50 sold out with 48 hours of its world premiere
Gordon Murray Automotive has announced a race-focused version of the T.50 supercar that will be even lighter, faster and more powerful. While all T.50 road supercars sold out within 48 hours of the world premiere, customer demand turned to the 25 super exclusive and very individual racing models.
Priced at £ 3.1million (before tax), the racing variant – dubbed T.50s – weighs just 890kg, while its Cosworth GMA V12 engine delivers even more power. The new car also has a 1758mm wide delta wing mounted at the rear of the car, which works with the rear fan, a new front splitter, underbody canopy and adjustable diffusers to generate over 1500kg. downforce – 170% of the car’s weight.
The historically significant official name of the new car will be announced later this year during its global reveal. More than half of the exclusive production has already been sold – before details were released. Murray now expects interest to rise as potential owners learn of the T.50’s revolutionary performance potential.
Professor Gordon Murray: “With an unwavering focus on performance, and without any traffic laws or maintenance considerations, the T.50s will achieve amazing performance on the track, demonstrating the full extent of the car’s capabilities. We’ve gone out of our way to push this car beyond the levels of anything that has been done before – it’s a celebration of British engineering and the vast motorsport experience of our team.
The completely redesigned T.50 features hundreds of major revisions for race and track compared to the T.50 road. The stripped-down interior emphasizes the track and contributes to the new car’s 94 kg weight loss. This improved weight reduction and the car’s phenomenal downforce ratio will ensure the car performs unparalleled on a racetrack.
One of the most significant additions to improve the performance of the T.50s is a 1758mm wide delta wing fitted to the rear of the car, which echoes the design of the front wing of the Formula 1 car. Brabham BT52 from Murray from 1983. The visually striking wing works with a new ground effect underbody wing, front splitter, adjustable diffusers and the car’s 400mm fan to generate over 1500kg of downforce – 170% of the car’s 890 kg weight.
While the road-focused T.50 has six different aero modes, the T.50 operates in High Downforce mode at all times, with the underbody diffuser ducts fully open and the fan running at 7,000 rpm continuously. / min. The fan cleans the air from the top and bottom surfaces of the car, with the flow under the body being accelerated through the car’s redesigned, steeply angled rear diffuser.
The other significant aerodynamic improvement over the T.50 at road specs is an aerodynamic spoiler that extends from the top of the roof to the car’s rear lip, dominating the rear profile. The spoiler improves efficiency and stability when cornering, as well as cleaning and channeling air over the car body to the delta wing.
In addition to optimizing downforce and cornering stability, the aerodynamic package also allows the T.50s to generate around 2.5G – 3G under braking.
Murray: “The design of the aerodynamics of the race car has been extremely rewarding. My love for motorsport really fueled the development of this car. The aerodynamics are so efficient that the T.50s would be able to drive in reverse, and could do so at as low as 175 mph.
Even more powerful engine
The Cosworth GMA V12 engine has been extensively reworked to extract maximum performance. Its power is now boosted beyond 700 hp thanks to completely revised cylinder heads and camshafts, a higher compression ratio, as well as an all new free-flowing exhaust system.
Murray: “Without any noise or emissions legislation, we could unleash the full potential of the GMA V12 engine and its 12,100 rpm. Over 50 components have been changed in the engine alone and the power can exceed 730 hp by incorporating the new dynamic air intake system.
The dynamic roof-mounted air intake of the T.50 has been modified to stand proud of the roof to maximize air intake above the car’s boundary layer. The periscope-style input powers the engine as speed increases, generating approximately 30hp of additional power.
To harness the power, the T.50s is fitted with an all-new six-speed Instantaneous Gearchange System (IGS) pre-selector system by Xtrac. The bespoke drivetrain features new gear ratios, optimized for speed, with steering wheel shifting replacing the manual road car setup.
Interior and racing controls
Inside the T.50s, the cabin is also completely performance oriented. The stripped-down space is devoid of the instrumentation, air conditioning, infotainment, storage compartments and road car mats. Again, the driver is seated in the center, this time in a new carbon fiber racing seat fitted with a six-point harness. To the left of the driver, there is only one passenger seat left allowing a co-pilot… or a very courageous passenger!
The steering wheel is a rectangular Formula 1 style carbon fiber design. Unlike a Formula 1 wheel, Murray has removed all controls except the essential controls for exiting traction and launch control functions, and buttons for activate the pit lane intercom and select neutral. The design allows for optimum grip and control, while providing perfect access to the wheel-mounted paddle shifters.
By replacing roadside displays, T.50 customers will be able to view readings that present key performance-oriented information, including lap times, G-forces, and critical vehicle / engine data.
Focus on performance
The T.50’s carbon monocoque is kept as the basis of the race car, but much of the rest of the T.50 sees significant changes, including body panels and every element of the chassis – mainly to minimize the weight. Under the skin, while the T.50’s up-rate suspension is carried over, the T.50’s spring stiffness, shocks and front anti-roll bar are tuned for racing.
Continuing Murray’s philosophy that even supercars don’t need fully tailored rubber, the new car rides on Michelin Cup Sport 2 tires. These are mounted on forged magnesium wheels which dramatically reduce mass. suspension of the car – another improvement offered without the need to take into account the kilometers traveled on the road.
Stopping power is provided by the T.50’s high-performance Brembo carbon ceramic discs with six-piston calipers up front and four-piston calipers at the rear. The brakes feature improved cooling via new ducts around each wheel – a development needed to deal with the extremes of heat that could be generated by 2.5G-3G braking forces while racing.
The oil cooling systems for the engine and transmission were moved to the sides of the car to improve airflow to the rear wing and allow the center spoiler. The T.50 also operates at much lower ride heights – 40mm lower at the front and rear – than the road car.
Each T.50 purchaser receives a complete “Trackspeed” individualization package that includes installation, training, racing and support. In an effort to provide a fully customizable and personalized racing experience, a wide range of adjustments can be made to the T.50s to suit each customer’s preferences and riding style. This individualized configuration process, together with the freedom to reign over exterior colors and liveries, ensures that each T.50 is unique.
Beyond the bespoke ergonomic configuration of the seat, steering wheel and pedals, the Gordon Murray Automotive team will work with each owner to configure the car to each owner’s specifications. Owners can fine-tune the suspension, chassis balance, and adjust the delta fender to optimize their car’s performance based on their driving style and requirements.
Murray: “I would like to run a series of racing events as part of our Trackspeed package to make sure the T.50s are driven regularly by the owners. There will be nothing like the experience of driving this car. And to hear it… well, it will be something else! I would like each of the 25 cars to be completely unique, from the setup to the paint finish. “
Murray and his team chatted with Stéphane Ratel from SRO regarding the potential of a GT1 sports club and a racing series for current supercars. The Gordon Murray Automotive team will offer a full line of stand, garage and support equipment for the T.50s.
Nearly two-thirds of the T.50 road car’s 100-unit production were pre-sold before its reveal; and each model sold out within 48 hours of the global unveiling on August 4. Already, more than half of the T.50 models are spoken. All 100 T.50 road cars will be built in the UK by Gordon Murray Automotive throughout 2022. Production of the 25 T.50 racing cars will begin in the first quarter of 2023.
