A distinguishing feature of the R88C compared to its predecessors was that it was powered by a new engine, the VRH30, developed specifically for racing. The car itself had evolved considerably as well, featuring a longer wheelbase (to both improve aerodynamics and make room for the longer engine)[2] and new cowl design. While the engine normally produced over 551 kW (749 PS; 739 hp) at 8,000 rpm,[1] it could make approximately 950 hp (710 kW; 960 PS) during qualifying.[2]
