The N55 has been setting standards from the start, as the pioneer of a new generation of engines in which BMW TwinPower Turbo technology with High Precision Direct Injection and VALVETRONIC variable valve timing plus a twin scroll turbo made its debut.

Thanks to intensive fine-tuning of the engine, BMW’s engineers have managed to extract additional performance from the engine while maintaining its exceptional fuel efficiency. With a maximum power rating of 225 kW/315 hp at 5,800 to 6,000 rpm, the 3.0-liter 6-cylinder engine reflects the sporty personality of the BMW 640i Gran Coupe and helps this automobile deliver brilliant performance. The high peak torque of 330 lb-ft, on stream between 1,300 and 4,500 rpm, ensures that the power is effortlessly and instantly delivered.

As a result, the 640i Gran Coupe can show off its prowess with a 0 to 62 mph (0-100km/h) sprint time of just 5.4 seconds. Top speed is electronically governed at 155 mph (250 km/h). All this extra performance comes with exceptional fuel economy and low emission figures. Fuel consumption in the EU test cycle is rated at 7.8 l/100km (30.1 mpg). EPA fuel economy ratings will be available closer to the on-sale date in the USA.
