Effortless excitement.

The six-cylinder petrol engines.

The six-cylinder Z4 Roadster models deliver efficient and powerful performance. The 195 kW 3.0si accelerates from 0 to 100 km/h in a mere 5.7 seconds, with the 2.5-litre versions following hard on its heels. The
160 kW 2.5si reaches the 100 km/h mark in 6.5 seconds, while the 130 kW 2.5i needs just 0.8 of a second longer. Even more impressive is the effortless smoothness with which these aluminium/magnesium engines deliver their power.
