Anyone seen this? M5 back with turbo V8 power - Autocar.co.uk. See below

Appears to just be speculation as to power, weight, AWD.

---

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

Jeesus, with every new article that comes out the BMW looses power. Now down to 552hp? That's even less than the X5M. 1830kg, or 4026lbs would be a godsend. How they shave 400lbs off an F10 550i is beyond me. That sounds too good to be true.

AWD will never happen IMO, with this being such a low volume car to begin with, and due to the extra weight. That said, with all that torque down low, it would be a nice thing to have to be able to put all the power to the ground.

Autocar of all magazines are the least likely to deal in speculation- if they are saying 552 bhp then unfortunately it seems that that is what it will be.

When Autocar are speculating they make it clear. They are positively asserting here.

I don't believe the Autocar article. If BMW wanted the information to be publically released, they would have released it at the unveiling of the concept along with the other information they released. I would also be surprised if they went with a number this significantly south of 600hp.

I wouldn't at all be surprised if BMW is quietly smiling as they read article after article underestimating the true horsepower rating (which they may have "leaked" intentionally), all the while knowing that once they announce the true (and higher) number, they will successfully push many ambivalent potential customers off the fence.

It is the weight claim that intrigues me; personally I'd much rather have a 1800Kg with 552bhp than a two tonner with north of 600 horses.

Autocar should be beaten about the head and shoulders - severely.

This is just really bad journalism. The numbers - HP LESS than the current BMW SUV. I'll bet the author doesn't even know what the XM 5 HP is.

And the weight equal to the E60 - evidently the author doesn't know anything about basic physics.

Okay then. Will you elaborate further?
Sure, if this car comes with 590hp/530tq, not one person would cancel their order they were planning on putting down on the car if it would have made 600hp. 10hp ain't gonna break the bank.

Even at 555hp like the X5M, if they could pull off a curb weight of 4000lbs, then it wouldn't be epic fail either.

Peak hp isn't the end all. This car will make so much more power under the curve it's going to be stupid. 200lb-ft more torque down low, an easy 100hp more in certain parts of the powerband, hello! This car will feel a ****load faster.

Will it also be significantly faster? Torque is just feeling to me. Helps it move really fast down low speeds but horsepower in the end wins the race. Get it? Like the E60 M5's topend gearing?

Will the F10 have something similar? Yeah. So.

Disinformation is the name of the game :grinyes:

There is no way the new M5 will only produce 552 horsepower

Why bother to build it at all then ?

God........I hope they don't go the Porsche route ( keeping it at 552hp and then offering a power "upgrade " kit to boost performance.

If the M5 puts out 600 hp - and THEN they offer a power upgrade - that's one thing


Don't think so however -

My call

607 hp ( Europe ) 600hp for the U.S - or close to it


We can only hope

What's "significant" to you? Torque is not just a feeling. If it wasn't for torque, you wouldn't have horsepower. ;) Get it?

I know what torque is. I have a SL55 AMG so trust me I know. My M5 still pulls harder on the topend easily.

Anyway, the F10 M5 for performance and marketing reasons should NO LESS than 590 something horsepower. Seriously. The F10 will also inevitably be heavier (unless they can make it lighter which will be a miracle) so 552 horsepower is NOTHING of a gain.

Part of the reason your M5 pulls harder up top is the 300+lb advantage, better aerodynamics, and most importantly, vastly better gearing. I also don't understand why all people care about is peak horsepower. Even if the F10 made 552 peak hp, it'd make 100+ hp and 200+tq more than the E60 through a good chunk of the rpm range. You're wouldn't just getting 52hp.
