Now that the Formula One season is freshly underway, it might be interesting to take a look at how the engine formula has changed from last season to this—and it has changed in a big way. By going smaller. It is almost analogous to the downsizing that’s going on in the auto industry in general.

Renault, which produces engines for a number of teams, including defending champion Red Bull, provides some data regarding last year’s RS27 and this year’s Energy F1. �

The engines are electrified, as well. But this is eAssist on steroids. There are two motor-generator units, MGU-H for exhaust recovery (H signifying heat) and MGU-K for kinetic recovery during braking (K for kinetic). MGU-H is connected to the turbocharger and takes power from the turbine shaft; the electrical energy can be directed to a battery or to the MGU-K. The MGU-K is connected to the crankshaft; under braking, it acts as a generator and recovers kinetic energy and under acceleration it acts as a motor to propel the car.
