With its sports-minded heritage, coupled with a passion to excel in the world's most competitive venues, Suzuki Auto drives toward another motorsports challenge with its entry in the World Rally Championship (WRC). Derived from the five-door SX4 Crossover, a prototype model of the SX4 WRC was first unveiled at the Geneva Motor Show in February 2006.
Developed as a driver-friendly World Rally Car offering excellent controllability under a wide range of rally conditions, this creation by Suzuki Sport, Suzuki's motorsports division, has involved extensive testing on many different types of surfaces. As a supplement to the testing, Suzuki Sport chose two events in 2007, the Rallye de France and the Wales Rally GB, to closely represent the majority of surface types. The Rallye de France is known as one of the most challenging tarmac events, and the Wales Rally GB, held later in the year, is similarly well regarded.
The SX4 WRC boasts a 2.0-liter turbocharged J20 engine with full-time 4WD drivetrain and a five-speed sequential gearbox. The vehicle's 1,997 cc engine delivers 320 brake horsepower between 4,000 and 4,500 rpm, along with a maximum torque of 590 N-m (435 lb.-ft.) at 3,500 rpm.
The SX4 WRC's powertrain features a carbon three-disc clutch, electronically controlled center differential and mechanical front and rear differentials. Its well-balanced chassis and rigid structure allow the front and rear MacPherson struts with coil springs work to their full potential, while Reiger shocks deliver dynamic, responsive handling. For tarmac, the vehicle is fitted with 20/65-18 tires fitted on 8X18-inch wheels. On gravel, 17/65-15 rubber is mounted to 7X15-inch wheels.
The SX4 WRC sits on a wheelbase of 2,500 mm, stands 1,450 mm high and weighs 1,230 kg (the minimum authorized). All specs reflect those of the final-phase development-test vehicle and are not necessarily indicative of the 2008 entry. As noted by Nobuhiro Tajima, vice president of Suzuki Sport, the endeavor is still in development, including the engine, transmission and suspension.
