What nobody has said yet is that this EcoBoost technology can be applied to V-8s as well... No, my friends, the V-8 will live on. New technologies like direct injection and homogeneous charge compression ignition (hcci) will ensure that. The number of cylinders has almost nothing to do with the kind of fuel mileage an engine can produce.
Well, i wouldn't go that far. I know what you're getting at but obviously if you cut the number of cylinders in half then you should theoretically cut the fuel consumption in half...but of course there's a lot more to it than that.
