U.S model to get more oomph
There are some articles and reports going around that the U.S bound Z4 will be getting more horsepower than the Euro spec'd model. While the European press has quoted 340hp for the M40i First Edition, the American press has yet to claim any official horsepower numbers. There is also a .2 second difference in the claimed 0-60mph time, which at first was thought to just an error. These reports indicate that due to new WLTP standards, that Euro customers could be robbed of up to 40hp.
