The six-cylinder version, which will be sold as the 640i, is powered by BMW’s latest 3.0-liter turbocharged inline-six with direct injection. In European guise, it pumps out 320HP at 5,800 rpm and 450Nm (332 lb-ft) of peak torque between 1,300 and 4,500 rpm, for a 0-62mph (100km/h) in 5.4 second and an electronically limited top speed of 250 km/h (155 mph).
In Europe, the 640i returns a combined fuel economy of 7.7lt / 100km (equal to 30.6 mpg US) with 179 g/km of CO2, compared to the 650i’s 10.4 lt/100km (equal to 23.1 mpg US) and 243g/km.
We suspect that the American version of the 640i will deliver the same output figures as the U.S.-spec 740i at 315HP and 330 lb-ft.
The 640i Coupe will reportedly arrive in U.S. showrooms about a month after the 650i at the end of October.
In addition to the news on the North American 640i, Autoblog also reported that BMW is preparing an all-wheel drive version of the 650i fitted with the firm’s xDrive system.
