BMW has revealed the first official pictures of the new Z4 roadster. The car will be on sale in the UK in the summer of 2003.

Characterised by convex and concave surfaces, hard edges and gentle curvature, the Z4 displays BMW’s new design language. It has all the classic hallmarks of a roadster - a long and sleek bonnet, a long wheelbase with short overhangs, wide track and a low centre of gravity. Luggage space has been increased to provide the car with a boot capacity of up to 260 litres, enough space for two golf bags.

The Z4 will be available with two six-cylinder engines. The 3.0i has 231 bhp and a top speed of 155 mph and the 2.5i, 192 bhp and a maximum speed of 146 mph.

The 3.0i features a new six speed manual gearbox. SSG, BMW’s sequential manual gearbox will be available as an option on both engine models. This second generation system features a modified six-speed transmission and enables the driver to make instant gearshifts via paddles on the steering wheel or with the gear selector.

Engineered to set new standards in its class, the Z4 has been designed with a focus on agility and handling. Featuring the modified rear axle of the 3 Series the Z4 has 50:50 front/rear weight distribution, fade-free high performance brakes, run-flat tyres and DSC III as standard.

New for the Z4 is Dynamic Drive Control or DDC which is activated by pressing the “sport” button on the centre console. DDC allows the Z4 engine management system to deliver an even sportier accelerator pedal response curve and change the steering weight to a more direct feel.

The Z4 will be available with an extensive list of options.
