REMARKABLE. DYNAMIC AND EFFICIENT.

The BMW TwinPower Turbo engines of the BMW 4 Series Convertible.

BMW TwinPower Turbo petrol engines. The nerve centre of the BMW 4 Series Convertible is its engine. BMW TwinPower Turbo technology combines innovative turbocharger technologies with Valvetronic including double-VANOS and High Precision Injection.

BMW TWINPOWER TURBO PETROL ENGINES.

The latest generation BMW TwinPower Turbo petrol engines feature remarkably agile power delivery and excellent responsiveness, even at low engine speeds. At the same time they are more efficient, with fewer emissions and better performance than their predecessors. These innovative engines combine the latest fuel injection technology and fully variable valve control including Double-VANOS with state-of-the-art turbocharger technology and represent a milestone in the BMW EfficientDynamics development strategy. The result is a particularly efficient drive train, which emphasises the renowned BMW engine prowess. The BMW TwinPower Turbo inline 6-cylinder petrol engine has been honoured multiple times with the Engine of the Year Award, bolstering its worldwide reputation for dynamic power delivery, extremely smooth running characteristics and impressive efficiency. The engines from the BMW EfficientDynamics range feature a technology concept that has been proven highly successful and is implemented in nearly all petrol engines.

*The published fuel consumption and CO2 emission figures are established according to legislated technical specifications (UNECE Regulation 101/UN Regulation 83 and SANS 20101 standards), which sets out the procedures that are used to measure the CO2 emissions and fuel consumption. The claimed figures are established using specific tests under standardised, carefully controlled conditions and may differ from consumption achieved under real world conditions with the influences of altitude, road surface, geographic conditions, vehicle options, temperature, humidity, tyres size and driving behaviour amongst others.
