Premium customers seeking a sporty version of the new BMW 5 Series (G30) will just have to wait until March 2017, when the luxury carmaker launches the new BMW M550i xDrive to the market. To be available just in Europe, the performance of the new 2017 BMW M550i xDrive centers on its 4,395cc petrol V8 engine that could deliver up to 340 kW (462 hp) of output at 5,500 rpm and up to 650 Nm (479 lb-ft) of torque available from 1,800 rpm.
Mated to an eight-speed Steptronic transmission, this eight-cylinder petrol engine allows the BMW M550i xDrive to accelerate from standstill to 100 km/h (62 mph) in just 4.0 seconds.
Already providing dynamic performance, the new BMW M550i xDrive is also fuel efficient. In fact, the BMW M550i xDrive consumes (combined) 8.9 liters of petrol per 100 km (31.7 mpg imp), and emits (combined) 204 grams of carbon dioxide per km.
On the other hand, the current M5 employs 4.4 liter V8 engine that provides 412 kW (560 hp) of max output between 6,000 rpm and 7,000 rpm and 680 Nm (502 lb-ft) of peak torque available between 1,500 rpm and 5,750 rpm. Mated to a seven-speed dual clutch transmission, the current M5 could accelerate from zero to 100 km/hour (62 mph) in 4.4 seconds and achieve an electronically limited top speed of 250 km/h (155 mph).
Interestingly, the new BMW M550i xDrive should be quicker to sprint from zero to 100 km/h than the current BMW M5 by 0.4 seconds, even though the latter boasts of higher output and higher torque.
