Recently, Formula One has take a greener turn, becoming more environmental by exchanging high-revving V8 engines for 1.6-liter turbo sixes in 2014.
In addition, changes to the 2012 regulations now make it mandatory that F1 cars run entirely on electric power for the entire time they’re in the pit lane. Rule 5.19 of the revised technical regulations states that, “The car must be run in electric mode (no ignition and no fuel supply to the engine) at all times when being driven in the pit lane.” To accommodate electric-only propulsion in and out of the pit lane, the new Energy Recovery Systems have been increased in capacity to 120 kW, and the system will also be allowed to recapture energy from exhaust fumes as well.
While a victory for technology in once respect, unfortunately it also means we will no longer be able to enjoy the high-pitched whine of the engine revving as the car leaves its pit stall. And with no sound to notify surrounding pit crews that a car is leaving, there’s certainly a level of danger involved too.
