The four-cylinder petrol engines sDrive20i and sDrive28i with innovative BMW TwinPower Turbo technology boast impressively high dynamics and efficient consumption. While the fully-variable valve control Valvetronic and the direct petrol injection lower consumption, the TwinScroll Turbo and the double-Vanos increase performance and response. Emotion and facts are intertwined in the sDrive28i: a powerful 108 kW (245 hp) help the BMW Z4 Roadster accelerate from 0 to 100 km/h in 5.7 seconds and it uses only 6.8 litres per 100 km.
The BMW TwinPower Turbo sDrive20i delivers an equally impressive performance: the 135 kW (184 hp) drive train uses 6.8 litres per 100 km and accelerates from 0 to 100 km/h in just 6.9 seconds. Whichever engine you choose, your decision is guaranteed to give you pure forward momentum.
