Gordon Murray Automotive has introduced the all-new T.33. It is the second newly developed model from GMA and joins the product range alongside the T.50, which has since been sold out, and the T.50s Niki Lauda. However, the mid-engined two-seat T.33 is a little less extreme than number 50.
The T.33 is powered by a specially reconfigured version of the T.50’s 3.9-litre V12 engine, co-developed with Cosworth and already recognized as the finest road-going 12-cylinder engine of all time. The beautifully proportioned, design of the T.33 is built on a newly developed superlight carbon and aluminum architecture. Its target total weight is less than 1100 kg.
Weighing just 178 kg, the 3.9-litre V12 engine revs at 11,100 rpm and produces 615 hp at 10,500 rpm and 451 Nm at 9,000 rpm. The ultra-quick response of the engine combined with 75 percent torque output at just 2,500 rpm and 90 percent of maximum torque available from 4,500 rpm to 10,500 rpm and a power-to-weight ratio of 564 hp per tonne according to Murray “an achievement of superlatives”.
While GMA and Cosworth have retained the V12 cylinder heads, albeit in a modified form, all-new camshafts, variable valve timing and new engine mapping have been introduced. A new exhaust system was developed along with a new intake system. The engine mounts, water cooling and oil cooling are also all new and have been specially developed for the GMA.2 V12.
The GMA T.33 is equipped with a six-speed manual transmission as standard, with a paddle shift transmission available as an option. The manual transmission is derived from the T.50 Xtrac manual transmission, which at 82 kg is the lightest supercar transmission in the world.
In order to ensure exemplary handling and a high level of driving comfort, the chassis engineers at GMA have developed a completely new chassis package for the T.33. Lightweight double wishbones are used front and rear in conjunction with coil springs over aluminum alloy dampers. The front suspension features an aluminum alloy anti-roll bar and struts.
The rear of the chassis uses aluminum alloy knuckles and tie rods, as well as an IASM (Inclined Axis Shear Mounting) system. With the IASM system, the rear wheel suspension is mounted directly on the gearbox housing, with torsional forces from the chassis and the entire drive train being absorbed by anti-vibration bushings.
The T.33’s carbon-ceramic (CCM) Brembo brake discs (370mm x 34mm front/340mm x 34mm rear) are paired with six-piston aluminum monobloc calipers at the front and four-piston aluminum -Monobloc rear calipers.
The T.33 rides on unique and exceptionally lightweight 19″ front and 20″ rear forged aluminum alloy wheels. The latter each weigh less than 7 kilograms. The wheels are fitted with Michelin Pilot Sport 4 S tires (235/35 R19 front, 295/30 R20 rear).
While there’s no rear fan involved this time, a ground effect intake at the front of the vehicle directs the air under the floor. A single-channel diffuser activated by ground suction behind the car allows for aerodynamic efficiency that is 30 percent more effective than a conventional ground-effect supercar.
This freed Gordon Murray and his design team from the need to outfit the T.33 with the wings, skirts and vents that grace most modern supercars. The only concession is the active rear spoiler, which unfolds automatically but can also be activated by the driver. The rear spoiler also features a high downforce mode that increases downforce and offers an aerodynamically improved braking function.
There are no touch screens in the cockpit of the T.33. Even the levers behind the steering wheel have been omitted, instead the indicators are operated with thumb buttons on the horizontal spokes of the carbon fiber valance. And while all the key controls are analogue and rotary, Apple CarPlay and Android Auto come standard.
The front storage compartment and the two side luggage compartments offer a total volume of 280 liters, big enough for 6 suitcases.
The T.33 will be homologated worldwide, including a full US homologation. With just 100 examples being hand built by Gordon Murray Automotive (GMA) at the company’s new global headquarters in Windlesham, Surrey, every single part of the vehicle is bespoke.
The specification process includes a bucket seat tailored to the driver. In addition, GMA’s Special Vehicle (SV) department can customize any T.33 to customer specifications.
Customers can choose between right-hand or left-hand drive and a manual or IGS paddle-shift transmission. Working with the GMA design team, they can configure their own bespoke ergonomics, interior trim and body colour. A wide range of options, including an SVS sports package, expands the possibilities for customization.
The first T.33 should be delivered in early 2024. The base price is £1.37 million. Without taxes, of course. That’s the equivalent of around 1.64 million euros at the moment.
