The C63 estate looks much better than the saloon.

B4 RS4? The first RS4 generation was launched in the B5 series.

I'm glad I could watch a video of the RS4 without the usual "Its crap because it won't drift" view. Benefits of 4 wheel drive shown here by the much slower Audi beating the AMG in wet conditions by a large margin! Nice video guys!

Who stuck that cheap asus tablet on the dash? Oh mercedes did.

C63 in the UK is good for about 8 months of the year. The RS4 you can go fast in and have fun year round. No brainer for me!

Steve, I used to stop watching your videos because I suffered an OD of drifts. Just let me tell you that when you don't spend your time sideways smoking tires, your reviews are more than excellent. Really ! Cheers.

RS4 is soooo much older but I would still take the RS4.

This is a legendary battle... Excellent review Auto Express team!

Do all Mercedes now have a budget looking 2012 era tablet stuck to their dashboard? It just looks awful and a last minute afterthought.

The fist pump moment when you hear Steve Sutcliife voiceover at the very beginning.

In a regular review it would be: the Mercedes can drift and the Audi can't so Mercedes wins. Then a whole bunch of stupid drifting for the pubescents to enjoy. I'm so glad this guy is different and objective. Awesome review.

Damnnn I was just waiting for this comparison. Perfect timing. Shoulda throw in the M3 in the mix as well. That would be even more epic to watch.

That RS4 sounds evil! Eargasm every time it reaches high revs!

Best Reviewer ever... nice comparison loved it !

Very interesting test, I personally much prefer the look of the RS4 but also the feel of the atmo engine, well the Mercedes may quicker, but how would it behave in the snow, people in Europe are often driving to go skiing. Thanks for sharing

and once again we saw how powerful and fast it is audi, and four wheel drive traction does its job!!! Very nice!

You could hear the Audi's cam chain starting to rattle more and more through the video. Let's hope Audi fixes that!

Great video SS :-) But B4...?

what were the dry times? Not suprised the merc is quicker, so much more power and torque these days. Just cant do NA anymore.

I just love the rs4 so much, but you should really bring out the rs6 or rs7! Drool. . .

I believe that these cars, even though track worthy, are never designed for somewhere like hokkenhiem or any other track, these cars are designed for the real world and in the real world, I believe the Audi would cream the Merc (even with the AWD) simply because if there is one thing Audi knows how to make, is a fast estate car and they've been at it for decades!. I remember when the C6 RS6 came out, everyone hated it but on real roads, no M5 or E63 could ever hope to come close, let alone keep-up with the beast. If you want a super-fast estate car and you buy anything other than an Audi, frankly you're a bit of a fanboy.

C63 estate looks so much better than the saloon, cant deny the C63 is alot more modern Cant wait for the new Rs4

So is it just me that notice that on the rs4 lap when they were changing the camara angles the window wipers were on and then off in other shots but yet they classed it as the same lap

Wasn't he going to Drive Magazine? He did publish a video about the Range Rover sport SVR with Drive

Which one sounds better, C63 or RS4?

Can you get the c63 in 4wd?

Did you guys drag race them? Please post a video if you did. Or consider C63 vs M4 track battle with a drag race

I think it's not a continuous video…because the viper works more in the view of hood camera and the viper works less in the view internal shoulder camera…

The Audi is on a 8+ year old platform at this point, the C63 spanking new. In 6 months you might get to pit the new RS4 against the C63. Given the advancement in the Audi B9 platform I'd imagine the RS4 will be the car to beat, in the dry or wet. the new S4 is almost as quick as the outgoing RS4 (and actually felt quicker when I tested it) and far better balanced. Its got a hideous tablet on the dash too however!

why are the saloon version compared ?

C63 not avail in AWD this year?

The original rs4 was b5 not b4 unless you were referring to the rs2 but dont know the chassis code for that

Mr. Steve at AutoExpress? Not anymore at Autocar? :)

Is it Blyton Park?

RS4 is my dream daily it’s just so dual purpose and that engine is nothing short of brilliant

Please, M3, RS5, and C63 in one video!

What about the b.m.w. estate car?

Wondered where Steve Sutcliffe had gone. Auto Express is now worth watching.

Car to Express... Good move Steve! :-)

What happened to AutoCar bro?

hahahaha this is brilliant, "at the end of the day when it was dry the Merc beat the Audi..." er ok, by how much? Bearing in mind a 1.5 second difference to the Audi (in the wet) and the Merc having a mostly dry/mildly damp track. I think the RS4 is the proper choice for the UK, you're not gonna be having "fun" in the car on the road anyway, sliding a big long estate car around... nah not gonna happen and they're aren't going to see a track unless it's a special occasion lol. Practically permanently greasy UK roads, I think it's safe to say the Audi all day long. Plus, why didn't you film the dry laps? If the reasons were based on what it was like in the cabin for the Merc and the way it drives normally then fair enough seeing as how they're apparently "equal" in terms of track times. But saying the most "fun" is a bit of a cop out in my opinion. I'm not hating here, it just seems like a contradictory result to me to what we actually see in the video, especially when you're praising the atmospheric V8 and it's revving out etc.

Even before watching I knew the RS4 would be quicker but that C63 has to be one of the most stunning estates in the world and let's face it how much track time are either of these cars ever realistically going to see. It might not be quite as quick but my money would go on the beautiful Merc...if of course I had the moeny. ;-)

People always forget about when winter comes, for Audi not a problem.

it seems there are no auto journalists that can control a throttle to not powerslide. jason plato and tiff are the only two who can do hotlaps without big sideways.

New shirt Steve?

The RS4 is the car to have!

When he said "the original B4 RS4", did he mean the B4 RS2, or the B5 RS4?

There was no B4 RS4 Steve m8

Why not the m3?

RS4 for me, What a good looking machine!

Nice Audi

Honestly though, who takes either of these cars out on the track? What really matters is every day usability and fun. And I think the C63 with its turbo V8 wins that category. What I miss from this test is how these cars handle B-roads and city streets. As well as interior quality, space and usability.

Well said at the end of the video, we'll take the one that makes you smile, but I mostly smile on these occasions: 1. during the winter when I'm overtaking cars on slippery uphill or when they are stuck, 2. when I see RWD drivers desperately trying to be perfect driver and pull out most of the RWD grip on the corners, and eventually spin, 3. Traffic light to light racing, in normal city traffic roads, not on those cleaned from the dust and oil and everything else ones like on the track. I have driven RWD myself, they are really fun, but an expensive one.

I love both so much. However the na v8 engine and Quattro in the rs4 just takes the cake, especially in the uk with our crappy roads and weather. Although between the b9 rs4 and the c63 estate; That’s the easiest decision on the planet. C63 estate all day

Stop changing the camera angle so fucking much

Serious question, who is really buying these high performance luxury wagons? Is it for space or ride quality? I can't imagine shelling out for one of these over a saloon, coupe, or suv. So what's the ace in the whole for these things? Do people actually like the way the look?

Frankly I'd take the one less likely to kill me but I'd wait until the new model on the new platform

I'm glad neither of them is available in the US, otherwise, I'd be tempted to spend far more money than I should on a new car.. (Audi would win for me though, due to AWD and vag-com compatibility.

This man is a maniac!

As long as Steve is the host the video is good

Will they ever learn to tell on what tyres the cars were during the test ? How can a big magazine like this still doing the same mistake.....

The distinguishing factor between these two cars is not so much about which one is the fastest. Their performances are pretty much similar. What matters is personal preferences to the exterior styling, interior design and badge. A Mercedes Benz fanatic will likely be biased against Audi even though Audi may edge the Merc in some aspects, and vice versa.

But isn't the Audi A4 on it's last days? Wouldn't it be better to wait with a a video until the release of a new? PS "I'm all for Mercedes"

Looks like so much fun lol

Since when did Sutcliffe leave Autocar and join Auto Express?

though you mention in the end about a dry lap , i would like to say something to auto express team . something that is a rule and must always be followed. WE DON'T TEST RWD CARS WITH AWD CARS IN THE WET ! NEVER !!!!!!! is it wet ? the test will take place the day after . again wet ? the other day etc until its fully dry ! no video in the wet guys . have that in mind . the reason is obvious ...

Of you test rwd vs awd then at least under dry conditions. Wtf...

So hard to choose

That paint tho...

What the hell Steve? Why don't you memorize a script or something. RS4 B4? Don't you mean RS4 B5 (2.7L V6 biturbo) the first RS4 launched in 2000 (or the previous RS4 B7 4.2L V8) the B4 is the RS2 , based on the Audi 80. Come on , you're better than that! Anyway , great review (and driving) as always! Cheers!

Mercedes AMG C63 that car !! i'm in love

Wasn't this guy on Autocar?

should have compared it with the rs6 avant !

Whats wrong with the sound 5:28-5:33

Lap in RS4 was done in the rain but the wipers weren't on in 1st person view, when every other view had wipers on...... understand you need footage for the video but it got very annoying.....

A what about the new RS4?

Steve Sutcliffe has left Autocar and joined autoexpress?

The Merc's interior alone is worth the win

sorry to break it to you but there is no such thing as a b4 rs4.... the rs4 started on the b5 a4 platform

AWD next year watch this space, now that will be immense

I'll have Mercedes, please. Thank you!

I bet you could make better time with the c63 if you drove it more concentratly instead of trying to fishtail

Mechanical clutch? That's why M is better with its electronic clutch. Mechanical clutch works as torque vectoring, eLSD can be programmed rather work as a lock diff or a torque vectoring. ///M>AMG. Well, oversteer is better than understeer in terms of quick. Is like on TG track, the M3 beat RS5 coz TG tracks are mostly fast corners where low end traction doesn't require that much.

Audi needs to come out with a re-design for the RS4. Audi all day baby.

I wonder if Audi will ever change the look of their cars, the a3 the a4 the a5 the a6 and the a1's front end all look the exact same. Ok the a7 looks slightly different but not dramatically at all.

If you buy a German car you should buy two that way you can rotate them in the repair shop when one breaks down drive the other one and continue the cycle

I highly doubt they'd ever be driven on public roads like they got driven on that track. So I'd go with the car that is slighly mad and fun. God help the C63 drivers if it's pouring with rain.

What is the point of an estate car it's not any more practical than a saloon.

I like the Mercedes c63 AMG and the Audi rs4

I thought C63 AMG only exist in AWD, not RWD. I was wrong then :p Btw... Why did you chose to test it in RWD when it is also AWD? Just wondering :p

This guy is not the best at multi tasking

Of course the C 63 is quicker ! Of course, on Rain, the RS4 is quicker, which is normal because 4x4. But in sense of sport cars, its important how the car handles. Like you said in the video, the 4x4 is understeery. And the C 63 has a very nice front end. So at this point the winner is clear. But we have to wait to the end to hear that the C 63 is quicker on dry road. This channel is the only one were i see Merc vs Audi on wet conditions. You guys did the same test with the old versions of these cars. But this time you were nice enough to say the truth at the end.

wagons on a track...does not look fun at all. AWD would be more safe and better handling with all the groceries...

Great both cars,but I think the new RS4 with 4,0TT will smash Amg on the wet and dry and drag race everything,like new RS3 kill all now;)

RWD is fun but AWD is untouchable.In next 20 years sport cars will play on super sophisticated AWD card.RWD cars touched limits

Winter tires on a RWD actually perform better than an AWD car.

Rs4 all day

There was no B4 RS4 ! Only B5 , B7 and this B8 RS4 have ever been produced.. There was a B4 RS2 Avant. That was back in 1994-95 , 22years ago...Really..?!?! Thats the one you are comparing this one with..?

Wow look at the arguing.

don't know why people don't like awd more. traction over power any day, all day.
