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.
The new range-topping Z4 model is set to adopt a unique styling package as well as a retuned chassis, with firmer springs and dampers and a reworked steering system for sharper dynamics. The tweaks are all in keeping with BMW’s recent M Performance models.
Among the visual changes that BMW design boss Karim Habib will bring to the Z4 are subtly reprofiled bumpers, altered light graphics and reinterpreted detailing, including new LED repeater lights along the flanks, as well as a new range of standard 17-inch and optional 18-inch wheels.
Inside, the two-seater is set to benefit from the latest version of BMW’s iDrive system, with new internet-based services. Sources also suggest that there are new instrument graphics and a revised range of trims in store for the Z4, although major changes to the dashboard architecture have been ruled out.
With new turbocharged 2.0-litre Z4 sDrive20i (181bhp) and sDrive28i (242bhp) models having recently being added to the range, the main changes to the engine line-up look set to centre on the existing Z4 sDrive35i. It is set to receive the latest version of BMW’s 3.0-litre turbo six, boasting an added 14bhp to take it to 316bhp.
