*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.
IN A CLASS OF ITS OWN. IN EVERY PERFORMANCE CLASS.
BMW TwinPower Turbo engines in the BMW 3 Series Sedan.
Discover the latest injection technology, fully variable valve control performance control and latest-generation turbochargers. All petrol and diesel power plants from the BMW EfficientDynamics engine family offer impressive strength – and astonishingly low fuel consumption and emissions. Particularly dynamic is the top-of-the-range engine in the BMW 340i Sedan.

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 represents 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.

BMW TWINPOWER TURBO DIESEL ENGINES.
The new generation of BMW TwinPower Turbo diesel engines is a testament to the rigorous application of the BMW EfficientDynamics philosophy. They combine top marks in power generation and performance with low fuel consumption. The diesel engines are notable for their excellent responsiveness and agile power delivery at all engine speeds, as well as for their low fuel consumption. They are renowned for their outstanding efficiency and dynamics, producing very few emissions and friction in order to guarantee maximum driving pleasure. The new diesel engines in the BMW EfficientDynamics range feature lightweight aluminium construction and one, two or three turbochargers with variable turbine geometry. They also come with the very latest CommonRail direct injection, which guarantees optimum combustion to further reduce fuel consumption and CO2 emissions.
