First of all, a HUGE thank you to Toyota of Long Beach20 minutes ago
A racing version of the Prius was unveiled by Toyota in 2013. This racing Prius replaces the 1.8-litre Atkinson-cycle engine with a 3.4-litre V8 RV8KLM engine which is mid-mounted in the car. The hybrid drive train of the car's production Hybrid Synergy Drive is retained but with a larger lithium ion battery. The RV8KLM is in fact the same engine featured in multiple Le Mans Prototypes such as the Lola B12/60 and Rebellion R-One. The car took class pole position and finished sixth at the 2012 Fuji GT 500km.
