BMW has announced the introduction of four new M Performance models, which are all powered by a diesel engine, the BMW M550d xDrive Sedan, BMW M550d xDrive Touring, BMW X5 M50d and BMW X6 M50d.
The new M Performance diesel models are powered by a new 3.0L six-cylinder in-line diesel engine. It feature three turbochargers and direct-injection for a total 381 horsepower and 546 lb-ft. The six-cylinder diesel is mated to an eight-speed automatic transmission and BMW’s xDrive all-wheel-drive system. The six-cylinder diesel also gets BMW’s EfficientDynamics technology, including Auto Start-Stop function and ECO PRO mode.
The fastest of the M Performance diesel models, the M550d xDrive sedan reaches 0-62 mph in 4.7 seconds and has a top speed of 155 mph. According to BMW, the M550d XDrive will also only consume 6.3 litres/100 km (44.8 mpg) on the European cycle. The M550d xDrive Touring will reach 0-62 mph in 4.9 seconds and consumes 6.4 litres/100 km (44.1 mpg); the X5 M50d reaches 0-62 mph in 5.4 seconds and consumes 7.5 litres/100 km (37.7 mpg); the X6 M50d will reach 0-62 mph in 5.3 seconds and consume 7.7 liters/100 km (36.7 mpg).
All four models get M-specific tuning of suspension, bodyshell mounting, engine and transmission mounting, springs and dampers, all standard and optional chassis control systems, and the Servotronic mapping for the hydraulic steering. The M550d XDrive and M550d xDrive Touring ride on 19-inch M light-alloy wheels, while the X5 M50d and X6 M0d models ride on 20-inch M light-alloy wheels.
As exciting as these new models may seem, BMW unfortunately has no plans to offer them to buyers in the U.S.
