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).
