BMW Z4 sDrive35is 480x280

Perhaps BMW forgot they had a line-up starting with a M, instead they give their latest Z4 model just an extra S. Luckily that’s a part of the full story. The new range-topper gets a higher level of performance and a more sleek and sportier look. The roadster gains an extra 34hp over the standard car, taking output to 340hp. The 3.0-litre six-cylinder engine with its twin turbocharger and High Precision Direct Injection increases maximum torque to 450Nm with an extra 50Nm of torque. The extra power is available in the upper gears, achieved by an extra short-time boost in turbo pressure.

All extras result in an improved zero to 62mph time of 4.8 seconds, down 0.3 seconds from the current Z4 sDrive35i. The top speed is electronically-limited to 155mph. The car – which should have been called Z4 M – comes with BMW’s seven-speed Double Clutch Transmission as standard. The gearbox is teamed with a launch control system which allows drivers to experience the maximum acceleration performance.

A sports exhaust provides a better exhilarating sound. The new exhaust system has acoustic flaps and a modified silencer to give the driver the option between a lusty performance car sound or a screaming beast. Adaptive M Sport suspension is standard for the BMW Z4 sDrive35is, giving a 10mm lower ride height than the standard Z4.

Easily noticeable is the new Z4’s bespoke M aerodynamic body styling package. A revised front spoiler configuration with contrasting matt aluminium trim in the side air intakes gives the car the aggressive looks it needs. 18-inch light alloy wheels come as standard (19-inch optional). At the rear a dual section diffuser with an Anthracite insert is another difference with respect to the standard Z4.

Inside, sport seats, door sill finishers with M designation, Anthracite headlining, Aluminium carbon interior trim and an M Sport multi-function leather steering wheel with shift paddles complete the package.

The BMW Z4 sDrive35is will make its official debut at the Detroit Motor Show in January and goes on sales in March 2010. The new Z4 M costs £43,885 in the UK (excluding taxes) or €48,841.78.
