The Civic Type-R continues in the footsteps of the Integra and Accord Type-R derivatives, delivering exceptional dynamic ability, innovative engineering and an exhilarating driving experience in a unique road car package.
Striking, purposeful looks are matched by a high output, 2.0 litre engine, which features Honda’s advanced DOHC i-VTEC technology. Applied to the Civic Type-R, output rises to a prodigious 200 bhp at 7,400 rpm, with peak torque of 144 lb-ft delivered at 5,900 rpm.

100 bhp/litre equates to a top speed of 146 mph, while a 30 per cent lighter flywheel and improved engine response for the MY 2004 Type-R have brought the 0-62 mph acceleration time down from 6.8 to an even more potent 6.6 seconds; yet combined cycle fuel consumption remains at 31.7 mpg.

i-VTEC is the generic name of Honda’s latest large capacity four cylinder petrol engine family. The name is derived from ‘intelligent’ combustion control technologies that match outstanding fuel economy, cleaner emissions and reduced weight with high output and greatly improved torque characteristics in all speed ranges.

The design cleverly combines the highly renowned VTEC system - which varies the timing and amount of lift of the valves - with VTC or Variable Timing Control. VTC is able to advance and retard inlet valve opening by altering the phasing of the inlet camshaft to best match the engine load at any given moment. The two systems work in concert under the close control of the engine management system delivering improved cylinder charging and combustion efficiency, reduced intake resistance, and improved exhaust gas recirculation among the benefits. i-VTEC technology offers tremendous flexibility since it is able to fully maximise engine potential over its complete range of operation.

VTEC

The principle of the VTEC system is to optimise the amount of air-fuel charge entering, and the amount of exhaust gas leaving, the cylinders over the complete range of engine speed to provide good top-end output together with low and mid-range flexibility. Typically, at high engine speeds the valves remain open for a longer duration to give the gases sufficient time to overcome their inertia. At low and mid range engine speeds, where valves opening for too long would allow intake charge to leak back out and exhaust gases to leak back into the cylinder, the valves remain open for a shorter duration.

The switch to the high lift, long duration operation at high engine speeds is achieved by locking the rocker arms operating each pair of inlet and each pair of exhaust valves to a third high lift rocker arm (one on the intake side, one on the exhaust side) by means of a hydraulically-activated pin

6-Speed Manual Transmission

Complementing the Type-R’s DOHC i-VTEC engine is a 6-speed close ratio manual gearbox. High performance synchronisers and the high efficiency changing mechanism allow extremely quick and precise gear changes.

The transmission is matched to a high performance clutch and features triple cone synchronisers on both first and second gears. Shorter in length than many 5-speed transmissions, it offers an exhilarating shifting feel as well as superior packaging. Carefully spaced ratios maintain engine revs well within the power band during acceleration.
