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.
As a result, the 640i Gran Coupe can show off its prowess with a 0 to 62 mph (0-100km/h) 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. Fuel consumption in the EU test cycle is rated at 7.8 l/100km (30.1 mpg). EPA fuel economy ratings will be available closer to the on-sale date in the USA.
Hi my name is Sha and I run this automobile blog. I am just passionate about anything that's has four wheels. I myself drive a used Toyota Vios 1.5E. Yes I know not exactly a pussy magnet. So any Bugatti Veyron owner wants to exchange their Bugatti for my Vios?
