Absolutly nothing been confirmed yet. BMW are saying nothing at this point. You hear all sorts of numbers right now so everything you hear are just speculations.
But, I didn't hear it? I read it...? So confused.

Between this Concept and the Production car we will see some subtle differences but it will still be an M5.
I agree that the BMW's rear is more busy than the E's, but the E's still looks more purposeful and sharp/dynamic to me, while the 5'ers looks more graceful to me.
i remember when everybody was speculating how much more power 1m's engine will have then z4 35is's and inthe end it was the same. Hopefully same wount happen with m5
BMW’s M division has gone back to the drawing board with the fifth-generation BMW M5, giving it a twin-turbocharged 4.4-litre V8 engine. It’s the first time that Munich’s iconic super-saloon has used forced induction rather than a highly strung naturally aspirated powerplant.
The F10 M5 is set to make its world debut as a thinly disguised ‘concept’ at the Shanghai show later this month.

The virtually unchanged production version is slated to appear at the Frankfurt show in September, with the car going on sale in the UK in November, priced at around £75k.
The new M5’s 4395cc forced-induction engine makes 552bhp and a thumping 510lb ft of torque — a solid 52bhp and 126lb ft more than the outgoing model’s naturally aspirated 5.0-litre V10, which is being discontinued after just seven years.
“Turbocharging provides more power and performance but with better fuel economy and emissions,” says Albert Biermann, BMW M’s head of R&D. The V8 is the same ‘S63’ unit used in the X5 M and X6 M, but with revised induction and exhausts for sharper throttle response and a more solid top end.
Official performance figures won’t be reveled until Frankfurt, but Autocar sources have revealed that standing-start acceleration has been improved by up to two-tenths of a second.
This points to a 0-62mph time of around 4.5sec — equalling the straight-line performance of its main saloon rival, the £73,415 Mercedes-Benz E63 AMG.
Top speed, like all M division cars, will be limited to 155mph, although a longer final drive ratio and taller gearing, made possible by the turbo V8’s hefty torque, lift the theoretical top speed to over 180mph.
BMW also claims a significant 25 per cent improvement in fuel economy over the outgoing V10, thanks to the inclusion of EfficientDynamic features such as brake energy recuperation, a disengaging alternator and stop-start function.
Expect the new V8 to appear in the new M6 coupé and convertible, on sale in the UK around spring 2012. BMW officials have also confirmed the potent V8 in the range-topping version of the four-door GranCoupé, Munich’s answer to the Merc CLS63 AMG.
Also new for an M5 is a Getrag seven-speed, dual-clutch gearbox with steering wheel-mounted shift paddles.
A four-wheel-drive M5 also appears to be on the cards, to satisfy demand from the snow belt in the US, where all-wheel-drive Mercedes/AMG and Audi models are selling well. “There will be some all-wheel-drive surprises on M cars in the future,” says Biermann.
Like all previous M5s, BMW has kept styling changes to a minimum. The concept’s deeper front bumper, with large central cooling duct for the intercooler, and the subtly wider front wings are all said to be production ready.
Also set for manufacture are the signature, chrome-rimmed side air vents and LED repeater lamps. At the rear is a subtle lip spoiler that increases downforce at speed and a reprofiled bumper with fully functioning central diffuser.
It’s all rounded off with a set of 20-inch alloy wheels shod with 265/35 ZR20 tyres up front and 295/30 ZR20s at the rear.
Despite the increase in size, the new M5 is expected to hit the scales at close to the old car’s 1830kg, due to a series of weight-saving measures, including aluminium and carbonfibre in the bodyshell.

This time BMW confirmed it will be significantly more power than X5M. I'm sure I read it somewhere.
My prediction 580 hp.
I can't believe that it'll only be 552 bhp. Out of all that extra fat induction plumbing? Heck, you could've achieved the same gains with a minor change in the software map.
Rear seem to be wider as well than previous M5



and you trust Autocar?
This is what Carmagazine says:
However, as befits the M5, we hear the V8 have a little more power than the 4x4 pair: reckon on 578bhp and 530lb ft, up from 547bhp and 501lb ft.
Autoexpress:
The big news is the drivetrain – the mighty 500bhp 5.0-litre V10 has been dropped in favour of a twin-turbo V8. Yet power is increased, with an output in excess of 560bhp promised.
Chris Harris from EVO:
The outgoing M5’s wailing V10 is set to be replaced with a twin-turbo 4.4-litre V8, similar to the 547bhp unit in the BMW X6 M, but it’s said to produce around 30bhp more
Autoblog:
Autoblog has learned that the 580+horsepower production M5 will debut at the Frankfurt Motor Show this September, and by the time it makes the scene...
Why wouldn't you trust Autocar? Their power figure is the most recently published and the only power figure published as a categoric statement of an exact hp figure (and torque too).
In the same article Autocar states :
Official performance figures won’t be reveled until Frankfurt, but Autocar sources have revealed that standing-start acceleration has been improved by up to two-tenths of a second. This points to a 0-62mph time of around 4.5sec
Thus making the case that Autocar know the difference between speculation and fact. I am inclined to believe 560PS / 552bhp is the power figure (in the absence of any further, more compelling evidence to the contrary).
I know this is a repost but I thought it interesting that Autocar would report on the numbers so emphatically:
I can't believe that it'll only be 552 bhp. Out of all that extra fat induction plumbing? Heck, you could've achieved the same gains with a minor change in the software map.

Despite the increase in size, the new M5 is expected to hit the scales at close to the old car’s 1830kg, due to a series of weight-saving measures, including aluminium and carbonfibre in the bodyshell.
Whats the point? its still a concept we see and not 100% production ready. there will be some changes for the M5. Wait a few months until we see the production car.

I thought the tweeks on the M5 would be minimal at best![]()
