Developed for customer rallying, the Opel Corsa Rally4 uses a turbocharged 1.2-litre 3-cylinder engine, front-wheel driver and a 5-speed SADEV sequential gearbox. Power is transferred through a mechanical limited slip-differential, while 3-way adjustable Öhlins dampers (low and high speed compression, rebound) allow the chassis to be adapted to different surfaces and conditions.
