The Mazda AER (Advanced Engine Research) MZR-R is a 2.0 liter, four cylinder, in line turbocharged engine. Designed from a clean sheet of paper, it is designed to make in excess of 500 HP, and on a per cylinder basis, more than an F1 engine. It is all aluminum construction and is mounted as a semi-stressed member of the chassis with A-frames.

The engine is the smallest, lightest and most compact in LMP racing today and there are no external belt drives or ancillaries. The camshafts, water pump and oil pump are internally driven by gears.

The engine has barrel throttles for optimum engine response with the latest Life Racing electronics for optimum engine control.
