Links are broken....
Whole photobucket's broken... They should be working anytime soon.
I wanna know how much quicker S6 is than 550i to 200km/h?
Also, did the use the updated engine or the old one in 550i?
Shitty Photobucket tests its new beta-version... sorry. Link are working now, but only as big sized images.
Not as bad as I first thought. One second slower up to 200km/h than S6 despite using the old engine. The new 445hp should close these numbers considerably. Also those midrange acceleration numbers the 550xi is faster than the others.
And where did that fake cop car come from?
Those in-gear figures, the S6 has seven gears vs eight in the 550i so this would suggest it's might be at a disadvantage. Would be interesting see if it's gearing that's effecting these results.
Yes, gearing is the main reason.
Here are the engine rpms at 80 kph:
S6: 2000 rpm (6.) / 1600 rpm (7.)
550i: 2900 rpm (6.) / 2400 rpm (7.) / 1900 rpm (8.)
Disadvantage and disadvantage. This is how the carmakers decided to specify their cars. Why should BMW give their car in an inferior gearbox just to be fair towards the S6
Numbers speaks for them selves. S6 is quicker to 100km/h and 200km/h and 550xi are quicker in-gear. The new 445 hp engine should close the numbers though.
The 550i used in this test looks VERY inconspicuous. I like that... I'm a sucker for sleepers.
This what I said about S6 in the S6 thread about this upcoming test:
I hope that 550i have the new updated engine with 445 hp, otherwise that S6 will leave the bimmer in the dust.
Obviously I was wrong. Yes, S6 is quicker but not by that much as I expected.
I think you have the wrong end of the stick I am not complaining only highlighting the probability at gearing is the reason for the impression the the e63 engine is the stronger one here. The reality is that it's actually the Audi's 4.0TFSi which is the more potent as proved in the allout acceleration runs.
Agreed, an extra 10% of power should close this gap quite a bit.
To me, it's an earthquake victory for the S6. It's the best looking, most aggressive, and has the best engine.
The S6 is one of the hot rockets this year, IMO.
There is more to it than just the engine alone, such as traction, gearing, weight. It's a combination of many factors. Or are you suggesting that the engine in S6 is more powerful than Audi says?
Well we already know the 550i has the gearing advantage, as for weight well there isn't a great deal of difference and since both are equipped with AWD so no traction advantage either which leaves output. So to answer your question of whether I think the S6 is more powerful than Audi says well I think I've been very vocal of this opinion.
The question I have is whether the difference in power figures between the S6 and S8 really 100hp? What I'm thinking is that the S6 is underrated and the S8 is probably making closer to the stated output.
In-gear acceleration times on auto 'boxes are meaningless. BMW thinks so too, BMW provides in-gear acceleration times for manuals and leaves autos blank on their UK website. Auto boxes kick down when you push the acccelerator... the S6 pulls away from the 550xi at every speed in this test. The S6 is the faster car from all speeds.
The BMW engine has only 12hp less (and 50Nm more) yet it is thoroughly outperformed by the Audi. I agree that the BMW needs 445hp to have a chance of keeping up with the S6. I didn't think I would see the day when a BMW needs a bigger engine and more power to keep up with a lighter Audi, it used to be the other way around.
The braking results aren't close either. The S6 is cheaper than the 550xi too. The decision here is easy, S6 all the way.
Ace, you have to agree though. Those acceleration times for 550xi is closer than we first thought. Like I said in the S6 thread that S6 will leave the bimmer in the dust. I was obviously wrong. I assumed that S6 would be around 3 seconds faster up to 200km/h, instead its only 1 second. Up to 160km/h the difference is 0.8 seconds. Not much to argue about.
The new 5-series is a heavy car (much more weight than E60) and weight is something BMW need to work on with their next 5-series (and 6er).
Personally I would not pick either A6 or 5-series. I go with either 3-series or A4. Better to drive, smaller, less weight and cheaper.
^Just_me, based on what we know about the gearing of each car I kind of wish Audi had stuck with the 8sp auto because then the S6 would have left the 550i for dust.
King of shocked that the BMW was as close as it was regarding their respective weights given that it's also the AWD version. Audi weight lose program isn't all it's bummed up to be.
I kind of wish the 550i had the new TÜ engine with 450 hp, and I kind of wish the car was a 550i and not a 550xi. I mean, that's two downsides for the Bimmer against a very good and brand new Audi...
Hmm, don't know. The 5er is severely overweight. The new A6 is much better in this regard.
