RS4b5"FEED ME"vsM6,996tt vs M6,996ttvsGT3-SUPER VI

[Nige_RS4]

This is all bull$hit - the M6 may be a might GT car, but no match for a GT2, which is over 300kgs lighter.

996 GT2 weight: 1440kgs power 462bhp (2wd) = 320bhp/tonne
BMW M6 weight: 1761kgs power 507bhp (2wd) = 280bhp/tonne

In order for the BMW to match the power/weight ratio of the GT2, it would need in the region of 565bhp.

Something is not right.

I bet that the SMGIII it gives the advantage to the M6 in shifting, and the GT2 like a pure track car as alot more drag than the M6, that means that in higher speeds (<200kph) they may have the same weight. So GT2 is made for track and M6 is made for straigh line.
Think in:
996C2 vs 996GT3
996TT vs 996GT2
M3e46 vs M3CSL
F360 VS F360 Stradalle
...

PS: The roads tests show me that 1 NA hp gives more power than 1 FY hp in the same car.

If you read earlier on this thead you will see that power is lost through transmission. BMW have got that beast torquey as <beep>, transmission is awesome hearing from the driver of the M5/M6

Believe me I was reading a 19page post this morning and trying to get my head round it all, but I can assure you it's true! The New M5/M6 are complete powerhouses.

Here's another Vid & write up


The Mercedes is tuned with different wheel in on the compressor and revs a bit more than standard. Also if I should beleive a post from the owner the catalysts are gone and other filters. Had been dynoed to 560 HP according to one earlier post, but that should be taken with a grain of salt. So different compressor internals "so the compressor works a bit harder" and ECU that is. "When the speedometerneedle is in hte bottom at 330 km/h it is still accelerating . Have witnessed acceleration still at 310 km/h via a Garmin GPS."

2 persons in the M6 and one on the SL55 AMG.

The BMW M6 is standard. The BMW M6 has S6 shift program on, EDC damping is set to hardest, P500 Sport is activated and DSC (stability control) is off. The race takes place in a closed area not open for the public.

It's not a GT2...It's a GT3 Mk1 (360 bhp)

Don't agree, the GT2 is RWD, so there can't be much in it. Also, the GT2 has 20% more torque than the M6. Does anyone have the video of the M6 vs. the GT2?

Also, the SL55AMG has a kerb weight of 1955kgs!!!!

Stevo, can you post a link to the discussion on the Porsche forum.

I think BMW are pulling a good PR stunt here.

Cheers, Nige.

Hope your ready for 19pages of mahem, there are loads of video clips, I think your looking at a good 1/2 hrs read and vid proofing, but do look at all posts from the start.

Seeing there has always been the RS4 v M3 going on for a number of years how will Audi take this!

What I mean is the new M3 is due for launch sometime in 2007, is it going to be quicker than the new M5? (that would be blistering performance)

Will Audi come back with something? (Turbo the new RS4, only joking!!!)

They are taking about the new 997 Turbo coming as 500bhp in standard and hitting 62 in 3.5sec (hate taking about 0-60 btw)

The video with the M6 vs TT from standing start looks somewhat strange. The M6 is spinning wheels in first gear and yet the 996TT doesnt seem to be flying away with the extra traction.....might the TT have had engine issues???

Exactly my thoughts when I first looked at the vid, but once you read all the posts and look at all the vids you soon notice that the M5/M6 is one "not so good looking" quick beast!

[Nige_RS4]

Right, I have read the full 19 pages over on the porsche forum, and there are some mis-truths being circulated on this and other forums. Yes, the M6 does beat the 996tt, mainly due additional power and lower transmission losses. If it was wet (much like today) then the tables would be turned for sure. The other tests were carried out from a rolling start, typically 100-200kph. It has been compared with other 4wd cars from the Lamborghini and Audi stables, and once again, has the advantages stated earlier. It has not been compared to a 996 GT2, but is has been up against a chipped 996tt, which was a pretty even match (none of these tests are very scientific BTW), but the 996tt still had the extra drag of 4wd (ever wondered why none of the F1 cars use 4wd). Any areodynamic advantage it might have is not seen until well beyond 200kph, so this is not a factor in these tests.

Kinda reminds me when the RS4 first came out - people were comparing it to all sorts of exotica, usually on perfect tramac in dry conditions - they missed the point for the UKs wet roads IMHO.

I still reckon a GT2 will beat it hands down in all areas apart from long distance cruising.

[911TT_STEVO]

mmmm! dunno like Nige, I personally think the GT2 would be similar speeds looking at the facts and figures. The main point here though, is that it's pretty frightening performance from a 4door family saloon. which you would agree anyway!!!

[DavidT]

but the 996tt still had the extra drag of 4wd (ever wondered why none of the F1 cars use 4wd).

Well, 4wd is banned if F1. They would not need it anyway for many many reasons, including: low vehicle weight, downforce, trick diffs, traction control, the most highly developed tyres in the world, few low speed corners, 2-4 standing starts in each race. F1 is not a good comparison to any road car IMO.

I thought the 911's had a good 4WD system that is 95% RWD (and therefore low transmission loss) when the rear wheels have traction?

Perhaps not the best of comparisons, eh , but even stuff like the BTCC is all 2wd - Audi had a venture in the late 90's (I think). I personally think that low vehicle weight would cause more wheelslip, therefore benefit from the extra traction that 4wd can provide.
