BMW 4 Series Gran Coupé : Engines

UNIQUE DYNAMICS. UNIQUE FUEL EFFICIENCY.

BMW TwinPower Turbo engines in the BMW 4 Series Gran Coupé.

BMW TwinPower Turbo technology has long been a synonym for the ideal combination of dynamics and efficiency. The engines in the BMW 4 Series Gran Coupé offer a mix of impressive power and astoundingly low fuel consumption.
For example, the BMW 435i. With 225 kW and acceleration from 0 to 100 km/h in 5.2 seconds, the BMW TwinPower Turbo straight 6-cylinder petrol engine is the best in its segment.

BMW TWINPOWER TURBO PETROL ENGINES.

Awesome power and a spontaneous response characterise the petrol engines in the BMW 4 Series Gran Coupé just as much as their fuel economy.
The BMW TwinPower Turbo 3.0-litre, straight 6-cylinder petrol engine in the BMW 435i (only available with Sports Automatic transmission) boasts particularly impressive performance figures: 225 kW, maximum torque of 400 Nm, acceleration from 0 to 100 km/h in just 5.2 seconds and a top speed of 250 km/h (limited). Average fuel consumption remains a modest at 7.5 l per 100 km, accompanied by CO2 emissions of just 174 g/km.

The 2.0-litre powerplants with BMW TwinPower Turbo technology were developed for greater driving dynamics and lower fuel consumption and emissions. The BMW TwinPower Turbo straight 4-cylinder petrol engine in the BMW 420i offers 135 kW and acceleration from 0 to 100 km/h in 7.5 seconds. Average fuel consumption is just 6.4 l per 100 km (8-Speed Automatic transmission: 6.1 l/100km), with CO2 emissions of 149 g/km (8-Speed Automatic transmission: 142 g/km).

The BMW 428i also sets standards in efficiency. While its 180 kW engine accelerates it from 0 to 100 km/h in 6.1 s (8-Speed Automatic transmission: 6.0 seconds), it can cover 100 kilometres with just 6.6 litres of fuel (8-Speed Automatic transmission 6.3 l/100km) and with CO2 emissions of 154 g/km (8-Speed Automatic transmission: 147 g/km).

*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.

BMW TWINPOWER TURBO DIESEL ENGINES.

The athletic nature of the BMW 4 Series Gran Coupè is evident under the bonnet. The straight 4-cylinder diesel engines with BMW TwinPower Turbo technology combine excellent fuel economy and low emissions with impressive performance.
