Page 1 of 2 Next >>  Gordon Murray Automotive has unveiled the exciting all-new T.33. It is the second newly developed model from GMA and joins the T.50 and T.50s Niki Lauda in the line-up. The two-seat, mid-engined T.33 has been conceived, designed, and engineered without compromise to offer the ultimate blend of performance, comfort, on-road driving experience and everyday usability.The T.33 will be powered by a specially reconfigured version of the T.50 3.9-litre V12, co-designed with Cosworth, and already regarded as the finest-ever twelve-cylinder road car engine. The beautifully proportioned, aerodynamically efficient, timeless design of the T.33 will be built around a newly developed carbon and aluminium superlight architecture. Its overall targeted weight is less than 1100kg. Professor Gordon Murray CBE: “With the T.33, our second all-new car, we gave ourselves a very clear brief: to create another timeless design. It has been designed and engineered to the same exacting standards as our T.50, with the same emphasis on driver focus, performance, lightweight and superlative, pure design, but the outcome is a very different motor car. This is a car where comfort, effortless performance and day to day usability are even more front and centre in its character.” As with all current and future GMA cars, the T.33 adheres to the seven key principles of the brand:
The T.33 has been designed by Gordon Murray and his team with strict adherence to the company's guiding seven principles. Based upon an entirely new carbon/aluminium superlight architecture, the T.33’s carbon fibre body represents a triumphant return to beauty. GMA spared neither time nor resources to pursue a perfectly proportioned, balanced beyond compare shape. Crafted through obsessive attention to detail, the T.33 exudes a spirit of purity and an aura of utterly timeless beauty. The T.33 represents the highest expression of automotive art that quite simply, no other company, no other car designer could have created. Each owner will be welcome to collaborate with the GMA design team to personalise their T.33 through their choice of colours and liveries, thus ensuring that no two cars will be alike. Professor Gordon Murray CBE: "The beauty of simplicity is the key to the design of every GMA model, and the new T.33 is no exception. As with the T.50 and T.50s, each component and every curve and radius is a bespoke design on the T.33 and is there because it has a function to perform. Our slavish adherence to the concept of engineering art extends far beneath the surface of the T.33's body. Every part, no matter how small and no matter that the owner may never see it, is designed to the same exacting standards as the body." The T.33’s new GMA.2 V12 engine is based upon the exceptional building blocks of the greatest road-going V12 the world has ever seen. The 3.9-litre V12 that powers the GMA T.50 road car has been significantly re-configured to deliver performance that is even more accessible than the extreme T.50 V12. Once again, GMA has turned to its Technical Partner, Cosworth, leveraging a relationship that has stood the test of decades and predates Gordon Murray’s first Grand Prix victory with Cosworth in 1974 at Kyalami with Carlos Reutemann in a Brabham BT44. The world-leading engine company's 60 plus years of experience has been mustered to meet GMA’s brief. Derived from the all-aluminium Cosworth GMA V12 and denoted by bespoke T.33 yellow cam covers, the beautifully crafted GMA.2 further embodies GMA's guiding principles, including Exclusivity, Lightweight, Engineering Art and, of course, Driving Perfection. Every element of the engine has been reassessed, with numerous components and systems re-designed and re-engineered to ensure optimum compatibility with the new T.33’s driving characteristics. Weighing a mere 178kg, the 3.9-litre V12 revs to 11,100rpm and produces 615PS @ 10,500rpm and 451Nm @ 9,000rpm. Incredible ultra-rapid engine response combined with 75 per cent torque delivery at just 2,500rpm and an incredible 90% of maximum torque available from 4,500rpm to 10,500rpm, and a power to weight ratio of 564PS per tonne results in superlative performance. While GMA and Cosworth chose to retain the V12 cylinder heads, albeit in modified form, completely new camshafts, variable valve timing, and engine mapping have been introduced to ensure perfection in response and power delivery. Along with a new ram induction intake system, a new exhaust system has been developed, which delivers a spine-tingling GMA signature sound unmatched by any other car on the road today. The engine mountings, water cooling, and oil cooling systems are also entirely new and were developed specifically for the GMA.2 V12. World-renowned British transmission experts Xtrac have created a totally bespoke six-speed transmission of exceptional quality for the T.33, which will be offered to customers with a manual gearchange or an Instantaneous Gearchange System (IGS) paddle shift actuation. The transmission is combined with a low inertia clutch and a Limited-Slip Differential (LSD). As standard, the GMA T.33 has a six-speed manual gearbox with a paddle shift transmission as an option. The manual gearbox is derived from the T.50 Xtrac manual unit, weight at 82kg, is the world’s lightest supercar unit. The paddle shift gearbox is designed around Xtrac’s instantaneous gearchange system (IGS) which delivers a seamless shift with no torque interrupt making it the world’s fastest supercar gearchange, without resorting to multiple clutches or dog rings. At 78kg it is the world’s lightest supercar paddle shift gearbox. In keeping with GMA’s determination to continually push the boundaries of automotive innovation, the powertrain of the T.33 is semi-structural, with the engine and transmission carrying all the traction, braking and cornering forces. GMA’s innovative IASM (Inclined Axis Shear Mounting System) incorporates anti-vibration mountings to ensure that excellent cabin Noise, Vibration and Harshness (NVH) isolation is delivered alongside precise handling. Professor Gordon Murray CBE: “The engine is the heart and soul of any supercar. And to ensure driving perfection, it must be bespoke, and it must be normally aspirated. We were fortunate that we had the world's greatest V12 from the T.50 as a starting point. Yet, nothing was taken for granted, and no part was automatically carried over without due diligence and consideration. When we once again joined forces with our technical partner Cosworth to create a bespoke engine for the T.33, every single detail was pored over in painstaking depth. Numerous systems and components were re-engineered and re-designed to pursue excellence, and we are 100 per cent confident that the GMA.2 V12 provides the perfect match for the T.33’s driving characteristics.” Page 1 of 2 Next >> |
