Running on bioethanol and producing around 280hp (209kW) from its 2.0L inline five-cylinder, the race version us up about 65hp (48kW) over the stock motor. Only a certain amount of tweaking of the top-end of the engine (cylinder block and heads) is allowed by the series, but Volvo managed to get the increased power by installing race-specific valves, cam shafts, pistons, connecting rods, and crankshaft. Maximum power is delivered at a screaming 8,750rpm and torque of 230Nm (169lb-ft) tops out at 7,300rpm.
Like most modern race cars, the C30 racer will use a six-speed sequential gearbox. The car remains front-wheel drive for the series, but receives a SACHS 184mm two-disc carbon fiber clutch upgrade. Helping to keep the power on the ground (and the torque steer to a minimum) is a mechanical differential with a torque controlled ramper and friction discs. Weight has been shaved to the series-minimum of just 1,134kg (2,500lbs) including the driver.
Front McPherson struts pair with a multi-link rear suspension. Both front and rear are fully adjustable. Brakes are provided by Performance Friction and feature four-piston calipers clamping radially and axially ventilated 332x32mm discs up front, with Alcon two-piston axially ventilated 290x10mm discs in back. Wheels are BBS-made 17-inch alloys all around, mated to Michelin slicks or rain tires.
