In fact, the M550i xDrive is already much faster off the line than an M5 F10, and now it can also have the looks to back that up in a visual manner. Thanks to 462 hp and 650 Nm (479 lb-ft) of torque and the inclusion of xDrive all-wheel-drive, the model can hit 100 km/h (62 mph) in just 4 seconds, so it's plenty fast even without an M Performance power pack.
That said, the six-cylinder 540i in both RWD and AWD guise can now get a power bump of 34 hp, to 360 hp, and 50 Nm to 500 Nm (369 lb-ft) of torque. BMW doesn't say how these improve the acceleration figures, but it does mention that the fuel consumption and exhaust emission values remain identical to the stock version.
The second 5 Series model to get a factory power kit is the 530d (both RWD and AWD versions), which has its output increased by 27 hp to 292 hp and 30 Nm to 650 Nm (479 lb-ft) of torque.
The cornucopia of M Performance tweaks for the 5 Series G30 also includes a set of redesigned exhausts for the gasoline models and a recalibrated Active Sound system, which makes the passengers feel like they're in a car with a different type of engine for the most part.
Optionally you can also tailor the exterior look of your next 5 Series with attachments to the front bumper, a rear diffuser, and a rear spoiler lip in a carbon fiber finish. Those rare breeds who despise carbon fiber and/or prefer or more subtle look can also get the rear spoiler lip and the diffuser made out of polyurethane (PUR).
Other than that, there are also new M Performance wheels, brakes and a bunch of subtle interior tweaks that significantly increase the number of M badges on the car. As always, since they come directly from BMW, none of these bits tampers in any way with the vehicle's warranty.
