Wonder what Weistec stuff was done on that 63?
That RS7 comes back strong on top my word!
Also wonder what stage 2 is on the M4. Seems like Jb4 + full exhaust (inc dp)
Could have PURE turbos. Doing 11.8 sec 1/4 on street tyres. Get that 60ft down to 1.7/8 with some slicks and it will destroy both those cars.
Yes Devon, I agree, but then if the Amg and RS also fit slicks the bimmer is stuffed again:roflol:
No replacement for displacement:cartel:

Stuffed in what way? The M4 beat the RS7 and lost narrowly to the C63 (black?) supercharged.
I am sure these guys are already running semis or slicks anyway. But then again wouldn't the slicks slow you down at higher speeds? Need someone in the know to confirm.

That RS7.... :coolShake:

RS7 : 2 tonnes, M4 : 1.8 tonnes. Not enough of a difference.
AWD > 2WD in a drag race

The M4 is nowhere near 1.8. Closer to 1.5. Where did you get your figures from?
AWD > 2WD in drag race yes, which showed in the beginning, but the M4 was stronger in the middle bit and caught up. AWD is heavy and struggles to put all the power down as the speeds increase. The M4 did lose a bit of steam at the end though.
You forgot one of the points I made earlier, that is its BMW engineering vs Audi.
Sorry, just checking that I am in the right forum. :YesNo:

Yeha. I have no idea where I got that figure from. I just took the first thing that came up in google, and I can't seem to find it now.Magneto said:
This is what doesn't make sense to me. Surely, SURELY, if 1 vehicle demonstrates a massive lead in the beginning, that advantage should carry over to the middle and latter part of a drag race. Why would the Audi, which can put down power very easily in the beginning, not be able to CONTINUE putting down power? What changed?Magneto said:
Bud, we are not comparing German to Chinese here. We are comparing German to German. You cannot tell me that you feel that Audi engineering is in any meaningful way inferior to BMW. Also saying "it must be the engineering" is tantamount to saying "I have no idea, must be witchcraft!"Magneto said:
I am not bashing BMW, I am bashing this particular race and the information given. Even if the Audi is 1/4 heavier than the Beemer, the Audi has 30% more power. And lets not even mention the Mercedes.Magneto said:

Sorry I got confused trying to deal with all the quotes in my reply, so this is a reply to all your points :roflol:
The Audi loses bigtime with quattro at higher speeds. This is where the M caught it up. That been said, the huge engine is able to push past what the M was capable of when it comes to top speed. It seems the M ran out of steam right at the top and that is where the Audi came back again. The M still won. Well that's my theory anyway.
BMW has always put the power down better than Audi. BMW handling is also far superior to Audi's. Driver feedback - the M has always been considered a sharp weapon and the Audi a blunt instrument. Although both German, BMW engineering is way better. Don't take my word for it, just watch some knowledgeable reviewers on YouTube.
Look what an RS7 stock does to an M6 or M5 stock from a standstill. Now let them go rolling over a longer distance.
So what you are saying is these races were rigged to make BMW look good? Perhaps you are right. Nothing will surprise me in this day and age, but personally I think the results are pretty accurate and there were no surprises for me.

No worries budMagneto said:
Not disputing this, at all.Magneto said:
Not disputing this either, but a drag race is not going to be influenced by handling, otherwise you could beat a top fuel dragster with a Miata.Magneto said:
Not at all! I have no idea if its intentional rigging, or if the Audi missed a shift, or if the BMW has undisclosed mods or if the Audi is talking crap about his mods.Magneto said:
All I'm saying is that the numbers and physics don't make sense to me.
BMW: 500hp / 1.5t = 333 hp/t
Audi: 750hp / 2t = 375 hp/t

I just brought this up in response to your one comment, to highlight the fact that altho they are both German, BMW are superior :rollsmile:
VukMiler said:
the M4 had 550hp / 1.5t = 366hp/t
The Audi had 700hp / 2t = 350hp/t
the Merc had 700hp /1.8t = 389hp/t
Coupled with the fact that it puts its power down properly and doesn't lose power to the wheels due to quattro. Also probably a bit more streamlined.
I still think its a feasible result?
Now Porsche are even better at putting their power down.
(hope my quotes worked lol)

Guys, you're forgetting torque/power curve etc.
Two cars with similar power outputs, say both with 500hp, can behave completely differently based on the power/torque curve.
The M4 is said to hit maximum torque and maintain it right from under 2000rpm. Now I don't pretend to know what this M4 in the video has had done to it, but I would imagine it also hits max power pretty soon and holds that power up until higher RPM. THe Audi on the other hand seems to have a more linear power band, reaching higher power at higher RPM.
It makes sense if the BMW is hitting higher power figures, say its full 550hp and torque at say 3500rpm, waaaay before the Audi has time to reach it's 700hp at top rpm. Also, take into effect the massive power loss to the wheels with the quattro system.
In any case... here is another video for you chaps.
