Hamann presents a comprehensive modification programme for the BMW Z4 Roadster, known internally as BMW Z4 Roadster E89. The optimisation of the series production control device has resulted in performance figures of 360 hp / 265 kW at 5230 rpm (standard is 306 hp / 225 kW at 2500 rpm). The maximum torque simultaneously increases to an impressive 540 Nm, which is available in the engine speed range of 1300 to 5000 rpm (standard is 400 Nm at 1300 - 5000). This modification results in a top speed of 285 km/h.
