Behold: the 600bhp BMW 1M Coupe
You may not have noticed, but we love a good bit of hyperbole here on TopGear, and this one's right up there. This is the G-Power BMW 1M Coupe. And it is the most powerful 1M Coupe... in the world.There must be something in the water down at G-Power's headquarters in Autenzell. Either that, or their spanners are charged with uranium, because they're fond of really, really quick cars. Witness the M5 and M6 Hurricane RR models.With the 1M, they are 'building the Coupe the way it should have come from the factory in the first place'. Which, if you take their viewpoint, means 600bhp and 579Nm of torque. Not from the standard 3.0-litre, mind. Oh no sir, they've slotted in a supercharged version of the M3's 4.0-litre V8, together with the seven-speed DCT auto box.From 3,000rpm, this modified unit apparently pulls exactly like the free-breathing V8 at 'twice the revs', but from 5,000rpm upwards, provides '40 per cent more torque, providing acceleration that feels like being dragged by a bungee cord'. Yowser.The ASA T1-523 supercharger - bolted onto the engine via an aluminium mount - features an aluminium cast air box with a racing air filter, a water circulated boost cooling system and eight lightweight integral resonance induction pipes. You can never have enough of those. There's a handmade stainless steel exhaust too.Performance? No word on 0-100kph (expect it to be very quick), but 0-200kph takes just 12.7 seconds, while top speed sits at 330kph. See? Quick.G-Power has fitted its Clubsport' suspension pack underneath - independently adjustable KW coilovers and dampers - with huge 396mm ceramic brakes, and 20in alloys with Michelin Pilot Super Sports. You'll remember of course, the standard 1M Coupe features the front/rear tracks and the diff from the V8 M3, which G-Power has wisely left untouched.There's a carbon fibre bonnet and boot lip, lots of leather and Alcantara inside, and a production run of just 30 - to mark G-Power's 30th anniversary next year.Fancy it, or is the standard 340bhp 1M more than enough BMW for you?
