The MGU-H (H=heat) recovers heat from the turbo/exhaust and converts it to energy either stored in the battery or sent to power the MGU-K (K=kinetic) directly. The MGU-H also controls the speed of the turbo, so it can speed it up to prevent lag. And F1 cars no longer have 'engines', they have 'power units'.

Probably right. The Aussie organizers are already talking about 'breach of contract' in regard to the sound of the cars. I'm sure the lawsuits are being prepared as we speak ...
