RPE RP-V8 is the name of a V8 engine series developed by Radical Sportscars in Peterborough, England for use in the SR8 sportscar. The design is loosely based on the 1.3 litres (79.3 cu in) inline-four engine produced by Suzuki for their Hayabusa motorcycle. The company have designed their own cylinder block and use existing Suzuki cylinder heads. The two cylinder banks are inclined at 72-degree angle. Lubrication is provided by a dry sump system. The engine is mated to a purpose-built transaxle designed by Quaife.
