Waiting patiently for the new BMW M5 Competition Package to arrive? Well, a fresh report has revealed supposed “leaked” specifications of the upcoming hotter version of the all-wheel-drive super-sedan, courtesy of a customer who has already placed an order.

According to a user on bimmerpost.com, production of the new F90-generation M5 Competition Package will start in July 2018, with first deliveries expected in September 2018.

So, what will set this model apart from the “standard” (for lack of a better term) M5? Well, the 4,4-litre V8 under the bonnet will apparently gain an extra 19 kW and 50 N.m, taking its peak outputs to 460 kW and 800 N.m. This, of course, would see it surpass the 450 kW power figure achieved by the Mercedes-AMG E63 S, but not quite match the Affalterbach machine’s maximum torque of 850 N.m.

The extra oomph will reportedly see the M5 Competition Package slice one-tenth off its claimed 0-100 km/h sprint time, which will thus fall to 3,3 seconds (again, just edging the E63 S). Top speed? Well, the post suggests a figure of 305 km/h, with the M Driver’s Package likely to be included as standard.

Other interesting specification details include the addition of a new sports exhaust, revised suspension (lower and firmer, according to the post), model-specific 20-inch Y-Spoke 789M alloys, black badging (including the word "Competition" under the M5 logo at the rear), a blacked-out grille, a gloss-black boot spoiler and an M Carbon engine cover. The report adds that carbon-ceramic brakes will not come standard.

Of course, we’ll have to hold fire until the official reveal of the new model for BMW to confirm these details (and provide a few more) ... although we apparently won’t have to wait long, with an unveiling expected in the second week of May.
