The same 335d is rated at 27mpg combined in the US, so using some math we can estimate that the 35mpg euro cycle figure for this new engine should translate to roughly 22.4 US mpg combined.

If it sounds like I'm ragging on this engine, it's because I kind of am. I just don't see the point of a gasoline 4 banger. It's not like it's anything radical or new. They could make a diesel 4 cylinder with the same horsepower and performance only it would get a very real US combined 35mpg. Now that would be an impressive engine. This? Meh.
I average 24-25 Mpg in the 135, your spline may be a bit off.

In EU , BMW offers a 60mpg car.
