#4 Kinetic Motor Generator Unit | MGU-K
MGU-K: Mercedes = 13, Ferrari = 12, Renault = 23, Honda = 13
Earlier known as Kinetic Energy Recovery System (KERS), the MGU-K is just like MGU-H. It is a motor generator unit which harvests kinetic energy, through engine braking. The MGU-K is capable of producing 160bhp, around almost the entire lap.
Mercedes and Ferrari were on point with their usage, Renault doubled their count with Ricciardo, Alonso, and Hulkenberg using 4 each during the season. Even Sainz, Verstappen and Vandoorne used more than the 2 MGU-Ks sanctioned.
Honda had to provide Hartley with a record 7 units of MGU-Ks for his Toro Rosso. This count makes for a very sorry reading for both Renault and Honda who are lacking in internal combustion engine power and also the recovered energy output too.
Honda did slip under the radar with a more accommodating customer in Toro Rosso as compared to a high profile McLaren the years before, but next year, Red Bull will demand more. It is a massive challenge for the largest engine manufacturer in the world to overcome.
