M5 to have 507hp and 520NM

[mv]

Finally some official info which throws some light on the M5's engine.

look at this table :

Interesting. The torque curve looks like it's on drugs. So this 507 hp. number is official I presume? I see the irony. They will probably advertise it as 500, and it's only a matter of time before we have tuners cranking much more out of the V10, depending on how highly tuned it is in stock form.

If the M3 CSL engine is anything to go by, the M5's V10 is probably close to it's limits, at least with stock componants. Being derived from F1 though, it could have a great deal of legs.

Power figures are not that impressive considering we have been expecting more...What does really impress me is its acclaimed 0-200kph time of 13s(or even slightly less).If it turns out to be true Audi's RS and MB' AMG have tough times ahead of them.

[LateNightCable]

507 is still impressive. And remember, this engine must be reliable, be reletively quiet and civilized, and carry BMW's 4 year / 50,000 mile warranty. 507 hp. and all of that, not too bad a deal.

It's certainly more than candy to me! I'm waiting for people to put up soundfiles of it!!

It looks like a peak too, not a boring linear powercurve...

What is not impressive, it's that torque figures. B10 Biturbo had same 520 Nm 15 years ago! And its almost the same as E39 M5's 500 Nm. The only difference is the 8500 rpm redline that gives extra 100 hp. But where can you feel this difference? Only on the racetrack, where you can constantly keep the engine in its optimal rpm range. In real life you usually cruise at around 2000 rpm and need to accelerate. In this situation you will have absolutely no advantage over E39 M5.

A 7 speed SMG has that problem pretty well covered.

If for what ever reason you do need to cruise at 2000rpm and then gun it theres the option of changing down a gear or three as you would in any other car to overtake on the highway etc.

BMW haven't designed a e55 torque monster engine they have opted for a more sporty approach and designed the whole engine, driveline and chassis to work together in the best possible way to reach their goal.

It would be foolish for us to believe that the e60 M5 is not better than the e39. That would have been BMW's first priority.

Exact same reason y i couldn't stand normal series BMW's.

The lack of torque never compensated for the ungodly weight they possess.

The torque's only 14lb/ft more than E39 M5. WTF?

Torque should be at least 440-450's since the HP has increased to 113 more. Kinda disappointing.

Hopefully the weight will be alot less or a considerable amount less than the E39 M5 in order 2 compensate for the lack of torque.

Yeah not normal for the Motorsport Ünd series to not have a "smooth as silk" torque curve, either. It is interesting.

I wonder, with the torque curve not so smooth, with the transmission will the car be a lil jerky in shifts?

The e39 and e60 engine capacities are almost the same so torque was never going to increase dramatically. if you compare torque with any other engine with about 5L displacement they've done ok.

[LateNightCable]

Not only that, but torque in the 300's has never really been considered shabby in it's own right. Most cars don't have anywhere near that.

I've never heard anyone say that an E39 M5 was sluggish off the line because of a lack of torque. And yes, count on the E60 M5 to employ a decent amount of light weight materials.

Yeah, you are so right.

Alot of people keep comparing torque to the e55 and rs6 which is expected, but lets not forget that the e55 has a 2.65 diff and the e60 would have around the same as e39 at 3.15. Not to mention probably about 100kg less weight and 7 speeds with serious rubber on the rears.

I'd still like my torque and eat it 2 .

BMW are making the M5 into a larger version of the M3's engine in terms of its charcateristics and it will be more "sporty". I think the throttle response will be excellent too and this will give the driver the impression that there is instant torque at disposal even if trickling along the highway at 2000rpm.

They wouldn't have tried to get the engine output numbers of their competitors using NA because its not possible without resorting to FI, they would be fighting a loosing battle. They are trying to skin their cat a different way.

Pictures of it, seems to be in the most final version...

Hmm. Looks nice, but I think that BMW might be thinking of giving the car some more Hp. About 550 or so. And the car is probably going to get a more stiffened suspension than planned, because the new M-chief, (former AMG-chief, but went to BMW instead ), would like it to be really stiff. Still, I'm really looking forward to the day, when it's going to go in production 8)

Despite my signature i still think that hp figures are not that important...what really matters is how it goes...and you can be sure it will blow away any of the current competitors.

I've got no doubt about that. The car is supposed to be as close as it can get in steering, handling and performance, as a racing car. The new M.chief, would like the car to be more stiff then it is at this moment... 8)

amg boss has come over to bmw?...lets expect supercharged powerplants in the upcoming M-series

I don't think that there will be any supercharged engines from BMW's M. That would break their traditions. The new M-chief, left Mercedes for BMW.....

just kidding

just kidding

But it might happen though. Maybe BMW should do just as Mercedes does: Give their cars a huge amount of powers, so much that the chassis can't handle it, just for show...

You naughty boy ...

According to the report that MV just posted, it looks like 507 hp. will be the official figure. - http://www.carpassion.com/en/forum/viewtopic.php?p=19062#19062

Does anyone here think that the M6 will pack even more punch? I'm thinking that, at least for simplification of production, the M6 engine will be tuned the same as it is in the M5.

Try to be funny just because BMW leaves behind?!

However, have you tried a Mercedes so strong that the chassie can't handle it? What model was that?

I'm sure they try them extremely much before they let the go out in production. 500 or even 600 is nothing. I've sat in a Escort Cosworth that was tuned to have 450 hp on the wheels! That chassie could even handle it!

I think that the M6 probably will be getting the same engine as the M5, but there might be some plans of building a CSL-version of the 6-series. The new 645Ci is a masterpiece on wheels, and I'd love to see the M6 version.
