The BMW 6-Series Gran Coupe will be offered as three distinct models in the US. The TwinPower Turbo 6-cylinder BMW 640i Gran Coupe is the initial model and arrives in late June 2012 with an MSRP of $76,895.
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, BMW’s engineers have managed to extract additional performance from the engine while maintaining its exceptional fuel efficiency. With a maximum power rating of 315 hp (225 kW) 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 BMW 640i Gran Coupe can show off its prowess with a 0 to 60 mph 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. EPA fuel economy ratings will be available closer to the US on-sale date, however the estimates should be in line with those of the BMW 535i Sedan which boasts an impressive 20 mpg city/30 mpg highway/24 mpg combined.
