T.50 GALLERY
The T.50 starred at the Goodwood Members’ Meeting on 16-17 October 2021. The much-anticipated new supercar made its public dynamic debut at the storied Sussex circuit, driven by three-times Indianapolis 500 winner Dario Franchitti MBE.
Dario admitted it ‘was a privilege and slightly terrifying’ to give the car its first ever public run, as he put the T.50 – and its 12,100 rpm redline Cosworth GMA V12 engine – through its paces over the weekend in front of a large crowd. Grinning from ear to ear, Dario was emphatic. ‘It gave me goosebumps. It’s just incredible.’ The most memorable moment? Probably getting wheelspin ‘north of 11,000’ as a he shifted from fourth to fifth on a damp track on the Saturday.
The bulk of the T.50’s hands-on testing is done at Millbrook in Bedfordshire, UK, one of the world’s most advanced car test facilities. There are 70 km of test circuits, including a winding and undulating handling circuit, a high-speed bowl and rough Belgian pavé. Millbrook’s environmental chambers are used to test the T.50 at extreme temperatures, from simulated Arctic freeze to Saharan summer sun.
Data measurement is essential. But just as important is subjective feel. With support from Dario the GMA test drivers judge steering feel, gearchange, balance, handling, throttle response, brake feel and much more, all essential to perfect the world’s greatest driver’s car. Gordon personally signs off the key dynamic areas.
DARIOS JOURNEY
RACING CHAMPION DARIO FRANCHITTI MBE HAS BEEN INVOLVED WITH THE T.50 SINCE THE EARLY DAYS.
Dario helped with the dynamic development work on the T.50. The Scottish-born driver piloted the new supercar at its public debut at Goodwood in October 2021 and has evaluated prototypes at Millbrook, GMA’s main test base. Dario is one of the UK’s most successful racing drivers, achieving most of his success in the US.
He is a three-times winner of the Indianapolis 500, America’s most famous motor race, and a four-times champion in the IndyCar series, America’s top single-seater racing category. Dario also won the 24 hours of Daytona sports car race (in 2008) and was BBC Scotland’s Sports Personality of the Year in 2007, the year of his first IndyCar and Indianapolis 500 victories.

This car is epic. It rewrites the supercar rule book. If that’s the full stop to the internal combustion engine supercar, it’s a pretty good full stop.

Creating the T.50
GORDON MURRAY REVEALS THE MOST DRIVER-CENTRIC SUPERCAR EVER BUILT
Gordon Murray tells Dario Franchitti how he designed the ultimate V12-powered, lightweight supercar at the GMA T.50’s global reveal on 4th August 2020.
From its central seating position to its compact footprint and unique, ground-effect fan, the T.50 rewrites the supercar rulebook.

Obsessive in every detail
T.50 SPECIFICATIONS












T.50 - the most advanced aerodynamics seen on a road car.
The T.50 takes road-car aerodynamics to entirely new levels. The rule book has been rewritten. To achieve unmatched aerodynamic performance, the car’s rear-mounted 400 mm fan rapidly accelerates air passing under the car, forcing it through active control ducts that, in turn, form part of the rear diffuser.
Through two automatic and four driver-select aero modes the T.50 is capable of increasing downforce by 50 percent, reducing drag by 12.5 percent, or cutting stopping distance by 10 metres when braking from 150 mph. In full V-Max Boost mode the system reduces drag to a minimum and, uses the car’s 48 volt starter-generator to drive the fan which frees up power, allowing a swift burst of boost up to 700 PS for short periods of maximum acceleration.
The aerodynamic systems on the T.50 are the most advanced yet seen on a road-going vehicle. The rear-mounted fan interacts with both the top and under surfaces of the car in an active and interactive way to increase aerodynamic efficiency and provide the driver with control over the aerodynamic performance of the car.














It all started with the ethos of lightweight.
Central to the T.50’s ability to deliver a truly memorable driving experience is its remarkably low dry weight of just 997 kg - around a third lighter than the average supercar. A key area where weight was minimised is the T.50’s fully carbon fibre monocoque and body panels, which total less than 150 kg. Inside, three racing-inspired seats are also constructed using carbon fibre, with the centrally positioned driver’s seat and the passenger seats that flank it having a combined weight of just 13 kg.
The Cosworth GMA V12 engine and manual Xtrac gearbox are also semi-structural, being mounted to the chassis. The powertrain is attached using an Inclined Axis Shear Mounting system (IASM). The engine sits on anti-vibration mounts to prevent unwanted noise and vibration entering the cabin, while enabling the effective management of braking, acceleration and cornering forces. This saves 25 kg of chassis weight at the rear of T.50, compared to a traditional engine mounting system.
At just 997 kg, the T.50 sets a new benchmark in the supercar sector. The very latest materials and technology have been selected for the car, ensuring that the T.50 will deliver vehicle dynamic performance and a driver experience like no other sports car. Every component on the car is an engineering work of art.
















The greatest V12 road car engine ever made.
The T.50 is powered by the lightest, highest-revving, most power dense naturally-aspirated V12 engine ever fitted to a road car. It produces 670 PS (equivalent to 172 PS per litre) and redlines at an astonishing 12,100 rpm. Such stratospheric performance has not come at the expense of usability on the road - with 479 Nm of torque, 71 percent of which is available from 2,500 rpm, the engine is extremely tractable.
Not to mention responsive - the V12 can hit the limiter from idle in just 0.3 of a second. The lightweight engine (178 kg) sits low in the monocoque, further enhancing the car’s agility.

The Cosworth GMA V12 represents the pinnacle of high-performance internal combustion engine design. The GMA V12 sets new standards in the areas of power density, rpm, engine response, weight and packaging. The GMA V12 will surely go down in automotive history as the greatest road-going V12 ever made.
















The world's lightest supercar gearbox ever made.
The gearchange of the T.50’s six-speed, H-pattern manual transmission has been meticulously honed. The result is a short throw with a narrow cross gate for slick, crisp shifts. Weighing only 82 kg, the Xtrac-designed gearbox’s aluminium housing is just 2.4 mm thick - reflecting the meticulous attention to detail that went into meeting the car’s packaging and weight demands.
While the first five ratios deliver potent acceleration, the final ratio is optimised for cruising, enhancing the T.50’s day-to-day usability.

The Xtrac-designed T.50 transmission is the lightest supercar gearbox ever made. The manual gear selection was chosen to deliver the ultimate driver/machine experience. The gearchange has been developed to optimise the throw and cross-gate action and the components are engineering art forms.






















Compact dimensions, a pure shape and a timeless design.
Design purity and balance was a mantra for the T.50’s development. Next-level aerodynamics mean there is no need to have exaggerated wings, vents and ducts that are the current supercar trend. Instead there are simple, timeless lines and clean surfaces, with compact, balanced proportions and driver-centric symmetry.
The dramatic dihedral doors are just one example of the ‘engineering art’ that runs throughout the T.50, which culminates in the spectacular view afforded of the V12 engine by the twin gullwing openings that span the rear half of the car.
The mission was to create a clean and pure shape that will remain timeless, ensuring that the T.50 will look fresh in thirty years' time.
For me, the T.50 styling represents a return to beauty in the supercar segment. The underbody aerodynamic performance has allowed us to retain a clean and pure upper surface. It was important to us that the T.50 had balanced shapes and proportions so that the design remains timeless.


















A driver-focused central seating position and tactile, analogue controls.
The T.50’s central seating position provides exceptional visibility and is flanked by two passenger seats - carbon fibre construction means the combined weight of all three is just 13 kg. The T.50’s controls are exquisitely made - the brake and clutch pedals are milled from solid aluminium, with the T.50 name laser-etched into them, while the accelerator pedal, gearstick and exposed gearchange mechanism are crafted from titanium.
The instruments are dominated by a large, analogue rev counter. With up to 288 litres of storage space, the T.50 is also a highly usable supercar.
The concept behind the GMA T.50 was to design a car which delivered the greatest and most involving driving experience for the owner. A key element of this is the T.50’s central driving position, but the interior design is also focused on delivering this experience with every human/machine interface for what must be the most driver-centric design ever seen.
