Suzuki has unveiled its latest design concept, and it could be a doozy. The road-going Hayabusa GT prototype, a compact coupe, is based on the successful Hayabusa single-seater, racing car one-make Japanese class. According to Suzuki, since the first of the open-wheelers took to the track, demand for a road-going version has grown.
Suzukis response has been a superlight GT coupe with 50:50 weight distribution, a low centre of gravity and minimal front/rear overhang. This bright yellow prototype is built on a short wheelbase and sports a sleek body with aerodynamics aided by a flat floor and a low-drag rear end.
Styled in a moving belt-type wind tunnel in the Suzuki Sport factory in Japan, the mid-engined GT drives the rear wheels, while the gull-wing door body is made from fibreglass and carbon fibre, fitted to a specially designed aluminium alloy space frame. Suzuki reckons it has added crash-worthiness.
The Suzuki Hayabusa engine, which powers the GSX1300R high performance motorcycle, is a 1,299 litre four-stroke, 16-valve, double overhead camshaft unit that revs to 11,000 rpm, producing 95 bhp at 9,800 rpm and 138 Nm of torque at 7,000 rpm. It runs at a compression ratio of 11:1 and feeds through a six-speed sequential gearbox. Weighing in at 550kg, it provides a power to weight ratio of 234 kW per tonne.
Suzuki says that, to assist the cars low centre of gravity, the exhaust pipe is located on the left side of the chassis rather than underneath. The company says it has endeavoured to use as many original factory parts as possible, not only to reduce costs but also to preserve the originality of the sports car.
The car employs double wishbone suspension and is fitted with 15-inch diameter, 6.5J wide aluminium alloy wheels, shod with 175/80 R15 tyres. Built on a 2,320mm wheelbase (or less than a production Suzuki Ignis), the Hayabusa GT is 4,050mm long.
While no plans exist to put this radical concept into production, the design is a showcase for Suzuki's technical innovation and provides a pointer towards future technology.
