Not to anything like the degree they did in years past. Checked the
mileage on a 400-horsepower Corvette lately? Its better than a
4-cylinder Citation would deliver back in the 80s.
The simple fact is that a truly efficient engine only uses as much fuel
as is demanded of it. Whether it is capable of 50 horsepower or 450
horsepower doesn't make all that much difference when its only being
asked to deliver 25 hp.
With today's cars, the shape and weight of the chassis itself is a FAR
bigger factor in fuel economy than engine size.
