FIA has met with F1 teams and potential manufacturers to discuss the regulations for the 2021 power unit in Paris. The overall objectives include “a reduction in cost, maintaining road relevance with hybrid technology and improving the sound of the cars and the appeal for the fans.”

The current 1.6-litre V6 turbo hybrid engine will be retained, but the running speed range will be 3000rpm higher for improving the sound. The MGUH unit for recovering heat energy from the turbos will be removed. A more powerful MGUK will be employed, with focus on manual driver deployment of the additional power, allowing drivers to save up energy over several laps as a tactical element to racing. FIA also proposed dimensional constraints and weight limits on the single turbo and intend to investigate tighter fuel regulations and limits on number of fuels used.

Additionally, Ross Brawn, Managing Director of Motorsports in Formula 1 said that fans’ opinions matter. “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 with the objective to define a set of regulations which will provide a powertrain that is simpler, cheaper and noisier and will create the conditions to facilitate new manufacturers to enter Formula 1 as powertrain suppliers and to reach a more levelled field in the sport,” said Brawn.
