The inline 6-cylinder engine (N55HP) in the new BMW 640i Gran Coupe will impress performance-minded drivers with its effortless power, exceptionally fast-revving temperament, outstanding refinement and exceptional fuel efficiency. 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, BMWs 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.
