BMW TwinPower Turbo 6-cylinder
Uncompromised driving dynamics: the BMW TwinPower Turbo straight 6-cylinder petrol engines in the BMW Z4 offer an enormous amount of strength, paired with comfortable running smoothness and impressive efficiency.
The BMW TwinPower Turbo engine in the BMW Z4 sDrive35i with two turbochargers, double-Vanos and petrol direct injection. The intelligent technology package enables dazzling performance values with simultaneously lower consumption: 225 kW (306 hp) and maximum torque of 400 Nm propel the BMW Z4 Roadster powerfully ahead. Combined with the seven-speed Sport automatic double-clutch transmission, this allows the vehicle to go from 0 to 100 km/h in just 5.1 seconds – with an average consumption of 9.0 l/100 km and CO2 emissions of 210 g/km.
The BMW Z4 sDrive35is goes even further: the most powerful BMW TwinPower Turbo straight 6-cylinder petrol engine has three litres’ volume and develops a sporty 250 kW (340 hp) and immense torque of 450 NM. Via boost function, this can be temporarily increased to 500 Nm. Combined with the seven-speed Sport automatic double-clutch transmission, this results in astounding sprinting abilities: it only takes the BMW Z4 sDrive35is to break the 100 km/h barrier. An extraordinary performance that only gets better with efficient driving behaviour: thus, the consequence of a combination of two turbochargers, double-Vanos and petrol is an economical average fuel consumption of 9.0 l/100 km and CO2 emissions of 210 g/km.
All diesel engines in the BMW Z4 already meet the requirements of the EU6 emission norm that comes into effect in 2014.
