What Is The Difference Between RW Power Output and Normal Power Output?

RW power output, i.e. RWHP or RWkW, is the power the car puts out, as measurable on a dynamometer connected to the WHEELS. Please note that even though RW stands for Rear Wheel, RWHP/RWkW is applicable in both cases (rear wheel and front wheel drive). The reason is, if you put as FWkW most people will read it as Fly Wheel rather than FW.

Normal power output is the output measure at the engine's crankshaft, which is about 15-20% higher than RW output.
