5 engines per season
100kg fuel=220 lbs of fuel per race
Lets assume 1kg of fuel equals 1 liter for maths sake (liter of pure water equals exactly 1 kg, ahh the marvels of the metric system) thats about 100 liters of fuel per race.
That is exactly the same amount of fuel my pickup trucks take from a dead dry state, I can get 600-700 kms from that fuel on normal unloaded driving.
However 1/2 of that fuel can be consumed in 27 1/4 mile WOT passes and thats with a 350 cube engine, max revs 5800rpm.
SImply amazing tech. in F1, but I admit the energy recovery systems are kind of lame from a certain aspect, but then again these systems are what we need for everyday vehicles. I understand why they are going in this direction, plus there is more sponsorship opportunities as well.
