MGU-K

The ERS unit captured waste heat as it was dispelled from the exhaust turbocharger, using an electrical device known as a heat motor generator unit. This waste heat was stored as an electrical charge until it was used by a complementary system called the kinetic motor generator unit. This device was connected directly to the drive train to deliver the additional power in the most direct and efficient way. in combination with the ERS-K it gave drivers an additional 161 bhp (120 kW) for thirty-three seconds per lap, compared to the KERS units used prior to 2014, which gave drivers 80 bhp (60 kW) for six seconds per lap.
