New Audi RS6 Perf v BMW M5 v AMG E63 S: DRAG RACE

Gonna need the real performance version of the RS6 not just the base MY24 to hand with AMG S and M5C

The M5C and CS are just magic sauce.

That is the real performance version and it held its own. Great off the line and it’s never going to beat the M5 based on weight alone… not to mention BMW always under rates its engines. For the RS6 to be right there, in a much more beautiful package and more practicality is exactly why I want the RS6. Now if NA had the M3 touring, that would be the winning combo of performance, practicality and price point for me.

Sad days for Mercedes… boohoo :)

no this is what I would consider a real performance model with true bespoke features to compete with AMG S and Comp.

The MY24 has performance in the name but really its a 30hp tune over the MY23 and nothing else. Other manufacturers wouldnt bother with a name change.

Yeah it’s only 30hp if you’re not paying attention to the fact that it’s dropped weight, tightened up the suspension, tweaked the throttle and the gear changes, and added significantly better rubber. If you ignore all that then you’re right it’s just the hp :)

Love the tweaks Audi has done - seems like they realized the stat sheet had to be notched up a bit after the initial RS6 release. Its not enough for me to think about trading in my '22 though...it took forever just to get this one can't imagine what it will be like for the '24! Hopefully inventory eases up soon for those ordering.

I'm happy to see the improvements Audi did however I won't ever trade in my 2021 RS7 for a performance model. The stage 1+ unitronic tune has been phenomenal. I've done a few launches with a m8 competition coupe and the RS7 just pulls hard and fast ahead without any hesitation. The current v8 engine has so much potential.

A M5 CS only has 27hp over the Competition Package so by your logic that is no more of a performance model than the RS6 performance

Did anyone watch the video? The RS6 P kicked some butt in the quarter mile. They should have used the RS7 (I know same stats)…I mean a station wagon and 2 sedans? Anywho these videos are always funny and enjoy watching them, but it would never sway my buying decision.

[CanuckRS]

Considering a Unitronic Tune, I had one from them on my old TTRS years ago and I had to send them the ecu.
You can buy a cable to do it at home now I understand?
Is there a noticeable power bump?

I've become used to 600hp it seems, a little extra would be nice now and again to make the kids sit up and pay attention to dad :)
Thanks!

Thanks for sharing this video with us. I am thinking about buying a new Audi RS6 and for that I am searching for its performance online and I am glad I found your post where you have shared a video with us which is very useful. Right now, I don't have enough money to buy it and that is why I am playing online casinos games to earn money and I am using this https://casinosanalyzer.com/online-c...ndyland.casino website to find those sites through which I am making money. When I have money to afford it, after that I am gonna purchase it.

I just came from 21 M5 Comp, to 23 rs6. And the CS is " rated" at 23 more hp over my old comp. But all the dynos are showing 65-75whp over the comps and my comp dynoed at 629whp in 105* Arizona heat. So take BMW ratings as serious sandbagging. Made the switch because the Rs6 is a better looking car hands down. But in a race my old comp is still going to wreck even the new Peformance. For a RS6 to run with a M5 comp it needs to be putting down close to 700whp because of weight. And for it to run with a CS you are going to need closer to 800+whp. The only advantage the audi has is its easier to get launch control to work. The Comp you have to have Jupiter in line with Neptune and it still only works on the 3 day of the month as long as the temp and humidity are perfect and only at sunrise. Ya its that bad

former M5 owner here. loved it and it's a brilliant car. I got the RS6 to try something new. the driving experience is more sporty and the acceleration is noticeably faster in the M5 right out of the box. the Audi is much more unique and has other things going for it. I was missing some of the intensity of the acceleration of the M5 though, so I got the APR 93 tune and it feels just as quick (maybe a bit quicker) than the M5 did. all of these cars are too fast for the streets as it is, so it doesn't matter to me. if there's one thing I wished to change on the Audi, I would take a larger fuel tank.

I see this RS6 has steel (yes, I know they are iron technically) brakes. I wonder how much of an acceleration benefit there is with ceramic brakes. I know the ceramics are not orderable for 2024 with the Performance in the US, but I wonder if they are available in other markets. Dropping 75 pounds of rotating mass has to help off the line for sure!

More importantly the performance has forged wheels that are 11lbs lighter each! That is yuge for acceleration.

Important yes, but I am not sure about “more important”.

Here it is in “non-moon” units :)

11 pounds (5kg) each gives us a 44 pound (20 kg) reduction in rotating mass. Carbon brakes give a 75 pound (34kg) reduction in rotating mass or a 70% larger reduction in rotating mass. Now the further form the axis the more important the reduction in mass becomes, but I imagine a lot of the reduction from the performance wheel comes from the thinner, smaller spokes and all the reduction is not in the barrel alone. With the carbon ceramics brakes, the reduction in rotating mass is exponentially proportional to the distance from the axis of rotation (i.e. the further away from the axis you measure, the greater the weight savings will be versus steel brakes). This is because the volume of the rotor is determined by taking the square of the radius (I.e. distance from axis of rotation).

Ok, nerd time over

[CanuckRS]

Before nerding out on the details, let's look at the big picture first.
When Audi states the weight savings, I wonder if they are quoting rotors only or rotors plus calipers. Audi does state the braking "system" is X lbs lighter.
Generally a CCB caliper will need to be larger and heavier but perhaps it's lighter in this application which would mean less of a rotational mass weight savings.
It's hard to believe that the ceramic rotors by themselves are that much lighter, how much do the steel ones weigh?
Anyone?

I do not know the exact weight of the OEM carbon rotors, but the OEM steel rotors weight about 135lbs (about 60kg) for all 4. The CCB’s and steel brakes on the C8 use the same size caliper, obviously the CCB one says “ceramic” and may have different seals for higher temps, but I believe they are the same Akebono 10 piston calipers.

This company advertises their ceramic conversion as saving 73 pounds (33kg) just from front and rear rotors alone. The density of carbon ceramic is about 20%-25% that if cast iron.

According to Shawn@PacificGerman in another thread:

46.5lbs - Iron 420mm Brake Disc (OEM)
24.5lbs - Iron 370mm Brake Dics (OEM)
...
20.5lbs - Oem Carbon Ceramic 440mm Brake Disc
11.5lbs - Oem Carbon Ceramic 370mm Brake Disc

definitely some new launch control programming there - that hole shot is impressive

i remember when i first drove an rs6 a couple years back, there was this really noticeable delay getting into heavy throttle from a stop, you could easily see it in review videos too, you could almost count 1 2 3 and then it'd start accelerating. i've driven basically all the mlb-evo 4.0's and they all have the same issue to varying degrees, and i think it's to do with the open wastegate programming at low rpm - i had same doughy laggy throttle in my rs3 with opf - after tuning it to keep wastegate closed at low rpm (to remove the dreaded wg rattle), it completely removed the lag

i've watched all the perf videos i can find, and it seems that's been sorted, the car accelerates off the line with far less delay - so if they've sorted the engine/turbo response in the software, it makes sense the LC would benefit from it too
