Has anyone here applied the techniques here to a turbo 4 cylinder luxuary car like a Saab? I know the 4 cylinder Saabs had the power and mpg of a V-6 but I'm curious as to what mpg they can achieve if driven softer. Would they get better mpg than a similiarly driven V6 sedan or would the mpg be about the same as the V6 sedan? If I could afford to lease one I would give it a try. A good test model would be the 9-3 2.0 turbo.
