I know there must be at least 5 automotive engineers monitoring our threads here so here is a thought for you.
Honda I believe sucessfully breached the electronic valve issue delving into variable valve timing.
Has there been an atempt to get this next step of variable engine displacement?
An example would be a 90 degree V6 where 2 cylinders are 4" and 4 are 2.5".
utilizing cylinder cut out and injector deactivation with all cylinders @ same stroke length The torque could be doubled for acceleration then dropped for cruising speeds and economy.
couple that to a hybrid with regen and electric boosters like formula one uses.
It could teach todays sports cars a nasty little lesson while providing 50+mpg???????
Not magic power just better utilization of it, with much less waste!
