The BMW M550i could be next in line to receive the updated N63 4.4 litre twin-turbo petrol V8, which first made its debut with the M850i, BMW Blog reports. Apparently, sources in Munich told the publication that the V8, which makes 530 hp, will be fitted to the M550i xDrive late next year, for 2020 models.

The engine in question will offer significantly more performance over the existing unit, which is also a 4.4 litre V8 that makes 456 hp and 650 Nm of torque. Together with the xDrive all-wheel drive system, the M550i rockets from zero to 100 km/h in 4.0 seconds flat. The new engine however, could potentially shave as much as 0.3 seconds off the century sprint.

As a recap, the M850i’s V8 motor produces 530 hp from 5,500 to 6,000 rpm and a whopping 750 Nm between 1,800 and 4,600 rpm. The century sprint is dusted in just 3.7 seconds, and uses fuel at a rate of between 10.0 and 10.5 litres per 100 km combined. And that’s not even the full-blown M8!

The report also said the update will introduce the Otto particulate filter, and the N63 engine will be standard on all models wearing the ’50i’ badge. That potentially includes the G05 BMW X5 xDrive50i, as well as the upcoming X6 and X7 models.
