You keep quoting 17mpg for the 3.0. It does 23 city and 33 hwy. Stop making up figures. Every EPA advertised fuel mileage I have (and most others) been able to achieve, or better, unless racing the car.

To answer your question, yes the S55 engine will be able to achieve close to 30mpg highway and be far cleaner than the S65. Power output isn't a key factor as I've tried to show you.

I used a BMW example as well as Mercedes example, but you chose to ignore that as it's abundantly clear that you're either clueless or trolling. Enjoy your motorbike.
