The BMW Z4 M Roadster will sit alongside a revised Z4 roadster range featuring new 2.5si and 3.0si models featuring more power.

Under the M roadster's bonnet is BMW's world-renowned 3.2-litre straight-six powerhouse previously seen in the E46 BMW M3 Coupé and Convertible.

The six-cylinder, 3 246 cc, engine develops 252 kW at 7 900 r/min and 365 Nm of torque at 4 900 r/min, and revs as high as 8 000 r/min.

The engine produces 78.75 kW per litre giving the Z4 M Roadster a power-to-weight ratio of 5.6 kg/kW.

This straight-six M3 engine rockets the two-seater Z4 M Roadster to 100 km/h in just 5.0 seconds, and on to an electronically limited top speed of 250 km/h.

M genes

It is fitted with a sports six-speed manual transmission, short throw shifter and M final drive.

The speed-sensitive variable M differential lock, borrowed from the M3 coupé, enhances driving stability and traction.

Stopping the Z4 M Roadster in its tracks is the motorsport-developed BMW M floating compound high-performance brake system as seen in the BMW M3 CSL.

The Z4 M Roadster stops in just 34 metres from a speed of 100 km/h.

Sporty styling

The Z4 M roadster boasts easily identifiable external and internal styling features.

The front air dam has an X-shaped combination of lines and openings, large air intake scoops, and low-slung kidney grilles as well as two striking feature lines on the bonnet.

Double-spoke design 18-inch light alloy wheels are exclusive to the Z4 M Roadster, while the rear view is dominated by the M trademark quad-pack large bore tailpipes inserted into a horizontal diffuser.
