higher or more miles per gallon is the same as reduced fuel consumption, so it is just US speak for improved economy. would need to look at a Clubby R8 fuel economy sticker to get a rough guide.Only if you have a heavier foot. All the VF's use less fuel due to weight loss and electric steering.
How can you possibly conclude the SS will use more?
we have had the metric L/100km system in aus for so long we are used to a smaller number in better.I understood his statement as meaning MORE miles per gallon, or better mileage?
