Cool BMW F10 M5 Prototype Reviews Roll In - 560hp - DCT - New LSD

BMW F10 M5 Prototype Reviews Roll In - 560hp - DCT - New LSD

More test drive reviews of F10 M5 prototype drives are trickling. Following Chris Harris' review last week, two German publications just published their first impressions on the F10 M5. Both Autobild and AMS confirm that a 7-speed DCT will be used, and both hint at an output of 560hp.

According to AMS, BMW has also developed a new Limited Slip Differential. While the actual lock is still performed by visco clutches it now is able to work proactive and build-up lock even before one wheel loses traction.

Here are some select quotes that caught our attention:

"Once the engine is started the new M5 welcomes you with a raw sound - When wanted the engine makes a raspy scream."

"In order to avoid the power merely making for smoke and rubber on the tarmac, a newly developed limited slip differential is set to improve traction. The well-known visco clutch has been retained, but it's now operating even before one tire loses traction. Depending on the pedal position and the resulting acceleration, a control system anticipates this and builds up lock."

"Driving in arctic Sweden on partially icy roads, the M5 stuns first and foremost in M Dynamic Mode which allows even average drivers to perform impressive drifts - without fully losing the electronic safety net."

Head over to Autobild and AMS for the orignal reviews in German and all photos. Autobild also published a short video.

We've translated both reviews below, just for you!

560hp?

0-62 in 4.3? I hope thats the time it took on the snow

WTF

Didnt BMW say "did you think we would give it less power than the x5/x6 M?"
so they gave it 5hp extra? Disappointment here..

Keep in mind its 1500 pounds lighter than the xm5/6 which when looking at power to weight of about 10-this is good for an equivelent of 150hp more than the x5m when taking power-weight into an account.

Another way to say that is to match the new m5 at 560hp the xm5/6 would need 710 hp-quite a signifigant difference.

However the big disapointment is in the acceleration. The e60 obliterated the e39m5 and this is a marginal increase in acceleration especially considering the e60 is a good 400 pounds lighter putting the total equivelent power within 20hp of each other. Better gas mileage sure but not a big difference.

Compared to the e39 which the e60 weighed the same however got 105 more hp. Disapointment however the e60 and s85 was so ahead of its time, it really was hard to improve on.

You mean massive body roll, a steering system that is not connected to the front wheels, and the engine note played through the speaker system?!?!?!?!

Yet you completely ignore the fact that the F10 is SIGNIFICANTLY heavier than the E60. The real question is if 60 hp will just negate the increase in weight, or provide a serious performance benefit.

Either way, I think 560 hp with what is likely to be a heavier chassis than the previous M5 would be quite a disappointment.

Im not comparing it to the X5M, just to what BMW said. He said it like: do you really think we would give it less power.. It seems like the engineers heard him say that and went "oh sh*t!" and just added a few measly 5.

How about slapping a couple turbos on the V10, theres and improvement on it. its an M, who cares about fuel economy

I was honestly thinking it would be ~600. Maybe the reviews are sneakily telling of whp.
doubtful.

I say 500hp is already enough. E60 M5 had enough power anyways.
Remember, M cars are not AMGs, meaning they are not made for drag races.
If you expected the new M5 to be a 4.0 sec car, then you should look at a different family sedan
I wouldn't mind taking extra 60hp with the turbos.

Are the X5M and X6M AWD? The M5 will be RWD. Maybe there isn't enough traction to contain 560 hp. Maybe launch control wasn't enabled. Just a preliminary test on a test mule. I'll wait until the production version comes out to judge.

South,

Remember I said they were working on a new LSD.

P.S.
Everyone seems annoyed at BMW's estimates for the M5, why? It is only an estimate after all and the true figure won't be known until it's independently confirmed, which I might add I reckon it will be low 4s bare minimum. Anyhow this car isn't about the first 60mph, it's all about the figures after this speed.

BMW tends to underestimate the performance numbers, so I'm betting it will be quicker than that.

The S63 has a maximum torque of 680 Nm or 500 lb-ft in the X5/6 M, and maybe even a bit more in the M5.

That was probably their goal
Is 400 extra pounds confirmed or rumor? Engine will save some weight going from a v10 to v8 and maybe they shed some more weight in other places. This engine with same weight as outgoing m5 would be awesome and overtake the cts v.

Who cares about the CTS-V. Caddy will just come out with a commercial saying "Faster than the BMW M5" with tiny tiny print saying "2010 model", which no one will read and then GMfans will cry their caddy as king. Sort of like the recent batch of Hennessy CTS-V wagon skits Vs 1-2 year old vehicles (Porsche 911 w/tiptronic & Nisson GT-R before the power bump).

M5s aren't exactly small agile track cars either, they are pretty close to muscle cars now. A C63 could take out an M5 on the track, the old one at least.

so gaining 170lbs of torque isn't improving?
