It's nabbed the title for world's longest drift, it's powered by a storming 4.0-litre twin-turbo V8 and it has scored very highly with our road testers. Now, the intensity dial has been flicked up another notch for BMW's M5 as details of a Competition version have leaked.
Posted on BMW M5 forum, Bimmerpost, which allegedly managed to snaffle the details from an Aussie customer who pre-ordered the car, the new BMW M5 Competition will belt out 460kW (625hp) -- an increase of 19kW (25hp) from the regular 441kW machine's 4.4-litre twin-turbo V8.
According to the leaked details, which trump the anticipated official reveal of the M5 Competition next week, torque remains unchanged at 750Nm.
Nevertheless, the power bump shaves a tenth of a second the 0-100km/h sprint from 3.4 to 3.3secs, while the 0-200km/h sprint is now 10.8secs -- an impressive three-tenths of a second quicker.
Crucially, on paper, the BMW M5 Competition is more powerful and slightly quicker than its arch-rival, the 450kW Mercedes-AMG E 63 S, which hits 100km/h in a claimed 3.4sec. Yes, it's all about bragging rights and chest-thumping pride at the top end of town.
Maximum speed for the all-wheel drive German monster remains unchanged at an eye-watering 305km/h.
According to the forum post, the M5 Competition is due to arrive in Australia in September, commanding a $30,000 price premium over the standard BMW M5's $199,900 plus ORCs.
If it's pegged at $229,900, it will undercut the Mercedes-AMG E 63 S ($239,611) by about $10,000.
It doesn't take leaked details to work out the new BMW M5 Competition will also benefit from similar upgrades to other BMW Competition models, such as stiffer, lower, track-biased suspension designed to improve lap times.
Expect more decibels and a gravelly note from an upgraded sports exhaust system and potential tweaks to the brakes as well. Cosmetic changes to the BMW M5 Competition will be subtle but based on the leaked photos show a new wheel design, and may include an even higher-spec tyre.
The front kidney grille has black outlines, as do the side vents. There's a black lip spoiler on the boot lid and small Competition badges on its flanks and rear. The interior is likely to benefit from special seats, unique highlights and badges, and the engine cover is now carbon-fibre.
According to the leaked details, Australian versions of the piping-hot BMW will also get a top-shelf Bowers & Wilkins stereo.
It seems BMW is looking at fleshing out its 'Competition' range as a fully-fledged sub-brand in its own right, as the BMW M5 Competition will join comp versions of the M2, M3 and M4.
Stay tuned for more details on the BMW M5 Competition.
