Formula One will have simpler, cheaper and noisier engines from 2021 as part of a “road map” for the future presented to teams on Tuesday that could entice new manufacturers to enter the sport.
“We’ve carefully listened to what the fans think about the current power unit and what they would like to see in the near future,” Brawn said in a statement.
He said the aim was to come up with regulations which, apart from making engines more affordable and louder, would also make it easier for new manufacturers to come in and for teams to be competitive.
The MGU-K, the electric motor that recovers and supplies kinetic energy from braking, will be more powerful with a focus on manual deployment along with an option to save up energy over several laps and create a driver-controlled tactical element.
The current engine, introduced in 2014 and much quieter than the previous V8s and V10s, ushered in a period of Mercedes dominance with the German manufacturer winning both championships for the past four years.
