Without a doubt, the new BMW M550i sedan is the most impressive 5 Series model ever built. Built buy BMW, tuned by M, the M550i is the jewel in the crown and a car that will excite many BMW customers. In March 2017 – just a month after the launch of the other 5 Series models – the BMW M550i xDrive will take over as the sporting highlight of the new BMW 5 Series range and as one of the fastest production series BMWs.

Packing a new, M Performance-tuned 4.4 liter V8 — featuring two twin-scroll turbochargers, a High-Precision injections system, Valvetronic valve lift and Double VANOS variable cam timing — the BMW M550i xDrive develops 456 hp and 480 lb-ft of torque. The latter of which comes in at an incredibly low 1,800 rpm. All of that power and torque is sent through an eight-speed automatic Sport Steptronic gearbox to all four wheels, via xDrive.

Thanks to that power and torque, the BMW M550i xDrive is capable of getting from 0-60 mph in under 4.0 seconds. That makes it the fastest non-M BMW 5 Series ever made. In fact, the only BMW 5 Series to have claimed 0-60 mph time faster is the BMW M5 Jahre, which claims 3.9 seconds.
