Styling changes to drop-top Z4 are only minor
Facelifted Z4 is expected to be launched at the Detroit motor show in January
A new range-topping M Performance model could give the roadster a timely boost in the absence of a full-blown Z4 M
Only light exterior styling tweaks and small changes to the roadster’s interior will distinguish it from today’s three-year-old model.
However, plans for a new range-topping M Performance model look set to give the Z4 a timely image boost in the absence of a full-blown Z4 M to go up against the likes of the Audi TT RS roadster, Mercedes-Benz SLK55 AMG and Porsche Boxster S.
The Z4 sDrive35iS expected to be replaced by a new Z4 M35i Performance model running essentially the same 335bhp turbocharged 3.0-litre straight six engine as the M135i hatchback, but with changes to its exhaust system for more a alluring sound.
