The long-wheelbase, short-overhang Impreza WRC2008 has shown improvements in stability and control, with the greatest theme surrounding the car being the huge advances made in the development of the new car's chassis. Additionally, the entire body is lighter, with improved weight distribution.
SUBARU's trademark symmetrical AWD system and horizontally opposed boxer turbo engine combination, coupled with the low centre of gravity chassis have been much more thoroughly investigated for this model. In terms of engine, the same power plant used to contest events since Monte Carlo, the opening round of this season, will continue in the new car. Cooling systems such as the radiator and intercoolers have been completely redesigned to accommodate the new body. The drive system, including the new lightweight gearbox, has already demonstrated reliability and rally-level performance.
The design department of Fuji Heavy Industries and SWRT jointly designed the new car. The planning of the body shell was the result of an accumulation of know-how and involvement from every department right up to the present. This also brought about improvements in aerodynamic characteristics and cooling efficiency.
