It's a car so quick it'll give a Porsche 911 a run for its money.
And for its size it's the most potent motor on the market.
That's despite wearing a barely budget £40,020 sticker price when it hits showrooms later this month.
And it's not just motoring where the 1 M sets new limits. This magic machine even manages to bring new meaning to the world of curtains!
Its ability to scythe through the air so efficiently is in part due to a new invention called the aero curtain.
The vertical holes at either edge of the front spoiler channel air THROUGH the wheel arches so it can blast through slashes behind them. This creates a curtain of air over the wheels to make the car more wind cheating.
Pulling power... two-turbo wonder but ordinary inside Despite an overall appearance that's more Rottweiler than greyhound, the rest of the bodywork has been carefully considered too.
There's a tiny lip on the boot lid to help push the car into the road and the wheels sit further apart than normal.
And even the door mirror shape has been specially tuned. The engine is pretty special too. It's a lightweight high revving six-cylinder with TWO tiny turbos that unlike one big one, work really well from 1500rpm all the way up to the 7000rpm red line.
Performance is eye watering. Because peak pulling power is achieved almost throughout the rev range and when you put your foot down it feels like it's never going to stop.
But to access full warp speed you have to press the magic M button on the steering wheel. And, being frank, if all cars featured one of these, the world would be a better place.
Instantly you have access to even MORE pulling power. It also dulls the reactions of the electronics that stop you spinning, making for a far more exciting steer.
Judging by the amount of time the orange light on the dash spends winking to say the electronic safety net is working, this car would be scrap metal without reining in its excesses.
Just in case things get a little too intense - it's very easy to stray into licence- losing territory with this thing - the brakes are brilliant making the combo as thrilling as a roller coaster.
Inside there are two things that are missing from most rivals.
A gear lever and clutch pedal. No sign of any flappy paddles to change gear in this motor.
The wheel itself is a chunky affair, as macho as boxing gloves.
But even that and the special suede bits splashed around the cabin can't stop the inside feeling a bit ordinary.
The exhaust note is also a letdown. While passers-by get a full-fat bellow from the four tail pipes, the people inside who've paid for the privilege get little more than a whimper in comparison. The only other drawback is the name. It would have sounded a lot snappier if BMW had called this the M1.
But that would tread on the toes of the firm's iconic 70s supercar.
And the 1 M Coupe already outperforms that beast. Nicking its name as well would be like a poke in the eye after a kick in the crotch.
This really is a graceless thug of a car. It's not one that's at its best on the run down to the supermarket. Unless you go via Brands Hatch.
But it is like a modern take on the old-fashioned muscle car. And it gives the letters BMW a new meaning: Bloody Marvellous Wheels.
MY VERDICT: If this motor was a bloke it would have offered you outside for a fight by now. It's fast and leery with bags of character - exhaust note from inside apart. Driving wise, it's one of the best motors that's ever worn the M badge. And in real terms certainly the cheapest.
