BMW M Performance Automobile is a new sub-division within the BMW AG, and is tasked in producing a wider choice of performance-oriented model independent of the M Division. With the debut of the sub-brand, in comes a trio of tri-turbocharged diesel powered all-wheel-drive cars/SAV. The vehicles in questions are made of a couple of F10/F11 5 Series, an X5 and an X6.
The model introduced are M550d xDrive (Sedan and Touring), X5 M50d and X6 M50d. As the name implies, all models channelled their drive to all four wheels, via an 8 speed automatic gearbox. The common powertrain for all of these variants are a newly developed 3.0L in-line six cylinder diesel engine, forced fed by three turbochargers. The 2,993cc engine comes with all the latest three turbochargers with variable geometry turbine, common-rail direct injection with piezo injectors with pressure of up to 2,200 bar. The engine produced 381bhp of power in the rpm range of 4,000-4,400rpm and a earth-pulling 740Nm of torque between 2,000-3,000rpm.
As the vehicles which this new superb powertrain varies greatly in size, the performance is independent of each others too. The fastest among this trio ( or 4 considering F10 and F11) is the M550d xDrive sedan, with its 4.7s 100km/h sprint. Fuel consumption is rated as 6.3L/100km with Euro 6 exhaust emission standard. The Touring version of this 5 Series is 0.2s slower and consume 0.1L/100km. Negligible difference really. The heavier X6 M50d is a tad slower at 5.3s century sprint and consumed 7.7L/100km of fuel and Euro 5 rated. The X5 M50d is the slowest-sprinting among these family with its 5.4s 100km/h sprint and slightly more frugal than its coupe-SUV sibling at 7.5L/100km. All models have a common 250km/h top speed. Has diesel cars have been as desirable as this? More detail and photos after the jump.
