BMW’s widely lauded TwinPower Turbo V-8 engine is updated with more performance and more efficiency in the 650i Gran Coupe
The 4.4-liter V-8 engine (N63) that powers the current 650i models receives an upgrade for the new 650i Gran Coupe. The unique “reverse-flow” engine, whose two turbochargers are positioned in the V-area between the cylinder banks is well known for producing an instantaneous and sustained wave of power, making it a delight for the enthusiast driver.
This new version of the engine adds BMW’s VALVETRONIC variable valve timing to the list of specifications. As a result, the new version of the engine (N63Tü) develops a maximum 445 hp between 5,500 and 6,000 rpm (a 45 hp increase), and makes peak torque of 480 lb-ft between 2,000 and 4,500 rpm (a 30 lbs-ft increase).
The new BMW 650i Gran Coupe completes the sprint from 0 to 62 mph (0 to 100km/h) in 4.6 seconds. Top speed is electronically limited to 155 mph. This engine also boasts extraordinary efficiency for a model in its output class. Its average fuel consumption lies between 8.6 and 8.8 l/100km (26.7-27.3 mpg), (provisional figures according to EU test cycle depending on tire options). EPA fuel economy ratings will be available closer to the on-sale date in summer 2012.
When the V8 is combined with the xDrive intelligent all-wheel-drive system, its power is converted into even more intense and dynamic acceleration. The electronically controlled power split between the front and rear wheels optimizes not only traction and stability, whatever the weather and road surface conditions may be, but also the agility of the Gran Coupe 650i xDrive Gran Coupe, whose sprint time from 0 to 100 km/h (62 mph) is just 4.5 seco
