If you want a BMW Z4 that’s more powerful than the M40i, you’re all out of luck. There are no plans that we know of to make a full-on M Division Z4, so for the foreseeable, the M Performance Z will be the most potent derivative.
But here’s the thing: the version sold in the US will be quite a bit more powerful than the European-sped car. BMW has revealed that the Stateside M40i will develop 377bhp from its 3.0-litre turbocharged inline-six, compared to 335bhp for those available the other side of the pond. ‘Murica!
If you’re happy with a drop in displacement and cylinder count, we now have details of the lower rungs of the Z4 ladder to bring you – up until now, we’d only seen specs for the range-topper.
The starting point will be the sDrive20i (which is not heading to the USA), developing 194bhp from a 2.0-litre twin-scroll turbocharged inline-four. It’ll do 0-62mph in 6.6 seconds, running out of breath at 149mph.
