**RPE RP-V8 ** is the name of a naturally-aspirated 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 L 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. There are currently two versions of the engine available, which have been updated for 2011. First is the base 2.7 L model which retains the original bore and stroke of the K8 Hayabusa design and produces 430 hp. Second is the bored and stroked 3.2 L model which produces up to 500 hp.
