Look at fords new 1.0 eco boost 3 cylinder..... 120PS 125lbft from 1500rpm to 4500rpm!!! The smoothness of a petrol the torque of a diesel but much wider power band!!

In america they are marketing this range of engines upto 3.5 litres as 'THE REPLACMENT FOR DISPLACEMENT'
They also produce a 1.6litre 4 cylinder with 180ps and the same torque characterisics
As I understand they will also be available in crate engine form with a standalone ECU!
This will change petrol power forever.
Now one of these on LPG would be the ultimate!
