BMW 6-Series Coupe from market launch, and both can claim unique features. These power units are kitted out with BMW TwinPower Turbo technology, including High Precision Injection petrol direct injection, and stand out with their instantaneous power development, majestic in-gear acceleration, outstanding refinement and exemplary efficiency for their output class.
The eight-cylinder power unit in the new BMW 650i Coupe produces maximum output of 300 kW/407 hp from its 4.4-litre displacement between 5,500 and 6,400 rpm. This unique engine, whose turbochargers are positioned in the V-shaped area between the cylinder banks, produces an instantaneous and sustained wave of power, making it a feast for the enthusiast driver. Peak torque of 600 Newton metres (443 lb-ft) is served up between 1,750 and 4,500 rpm. The sporting performance attributes of the V8 engine enable the new BMW 650i Coupe to accelerate from 0 to 100 km/h (62 mph) in 4.9 seconds, leaving the engine electronics to call a halt to proceedings at 250 km/h (155 mph). And yet the range-topping model also demonstrates extraordinary efficiency for this output class, recording average fuel consumption of 10.4 litres per 100 kilometres (27.2 mpg imp) in the EU test cycle, together with CO2 emissions of 243 grams per kilometre.
The new BMW 640i Coupe is powered by a six-cylinder in-line engine in which the BMW TwinPower Turbo technology brings both direct injection and VALVETRONIC fully variable valve control to the table. This combination optimises both the responsiveness and efficiency of the 3.0-litre powerplant, which generates maximum output of 235 kW/320 hp at 5,800 rpm and puts its peak torque of 450 Newton metres (332 lb-ft) on tap between 1,300 and 4,500 rpm. The BMW 640i Coupe completes the sprint from rest to 100 km/h (62 mph) in 5.4 seconds, and its top speed is electronically limited to 250 km/h (155 mph). Average fuel consumption in the EU test cycle stands at 7.7 litres per 100 kilometres (36.7 mpg imp), while CO2 emissions come in at 179 grams per kilometre.
