Designed by Colin McRae and Dave Plant and built by DJM Race Preparation, the McRae R4’s chassis is based on a steel safety cage with carbon paneling front and rear, and a steel-covered cockpit area. Suspension consists of twin wishbones with Proflex dampers. The body styling has been done by Keith Burden and Tom Webster. It appears that some components of the vehicle have been taken from existing production cars, the doorline in particular appears very close to that of the Ford Ka.
The engine is a naturally-aspirated 4 cylinder, 2.5 litre Millington Diamond Engine producing 350 BHP. Transmission is via a six-speed gearbox, manual or semi-auto, and by mechanical front and rear differentials with the option of mechanical or active central differential. The car can be produced in either 2 or 4 wheel drive formats.
