...to sum up
an F1 engine is built in such a way it will be good at what it does..that aint a compromise thats perfection as they know exactly what is needed..it doesnt need to have a smooth idle or run on unleaded fuel or do 40 mpg etc etc
..the dragsters again ,its built to do that job it doesnt need to do more
..the road car engine again is designed to do a job where is the compromise its economical fairly fruity and does what it says on the tin nothing more nothing less
