/predicts an outcome of the CSL killing the SLK before watching

//watches to see if it comes true

edit:

Ha, yay for psychic ability! That's what the SLK gets for being a fat ass pig.

True, it really helps the CSL's cause to weight over a hundred kilos less then the SLK, especially as official numbers give it something like 4.6 seconds 0-60 versus 4.9 for the SLK (although some reviews clocked the SLK at 4.3). Still, not too bad with the SLK having an initial launch advantage and keeping up to the CSL even though it weighs several hundred kilos more (the CoD also helps I guess).

However, I don't understand what they say about the brakes fading? Obviously brake torquing will heat them up, but I've yet to experience something like this on mine, and those who track their 55's say that the brakes hold up extremely well with little or no fade at all. After all, it has been common knowledge that the CSL brakes are quite poor, being of the biggest criticisms the new Z4M and MCoupé have received from the press (they use the CSL brakes).

Also, brake torquing is not necessarily the best way to launch the SLK. The torque causes a lot of wheel spin in such cases (even with brand new tires), and I didn't get this "feeling" from the video. It should have definitely squealed/shuddered more then it did if they launched the car with brake torquing. Even with ESP turned off...

It seemed a bit "staged" to me, but I can't say for sure. It's not really possible to tell from the video. Is the SLK properly broken in? I know I got a decent surge of extra power after I passed approximately 10,000km's. The engine just seemed to breath better. And for anyone who has seen my quicktime vids of me launching my car from a stop, they will immediately see the difference between the amount of shudder and squealing produced with my car, versus the stuff that can be seen in this video

But, who knows...

Anyway, the general consensus is that the SLK rims are not wide enough, causing it to have poor "off the line" grip in regards to the torque it has. For example, SLK rims are only 245 in the rear, whilst it's 265 on the CSL. This is the biggest reason for it squealing like it does, with the ESP system kicking in. Could be the owner replaced his rims with wider ones.

So we've got the lighter and more powerful edition of the M3 (which btw is definitely slower then my SLK, I know since I raced a friend's M3), versus the standard SLK. What I want, is to see what the outcome is if the CSL is pitted against the lighter and more powerful 'special edition' SLK being released in these coming months? I guess it's kind of the "CSL" version of the standard SLK

I still prefer convertible action, and if it means that the car is a bit heavier and slower then the CSL, it's no big deal

Good riddance to the CSL. We already know it's one of the better cars out there. I'm happy to see the SLK be able to keep up with it.

Nice set of videos. It doesn't look staged to me, but maybe the SLK isn't launching as hard as you do. The M looks much stronger than the SLK in the video, given how it pulls and how it catches us in one of them. Nice seeing them dust the motorcycle who was splitting lanes. I hate that.

Its not fake. The SLK55 owners also own a M5 E60 and he is a member on m5board.com and mbowolrd.org. This isnt a fake movie, its the real deal.

He was certain he was going to win this race, particulary in high speeds so he was surprised the CLS beat him. But he is still happy, its not like he is selling his SLK55. Sometimes you win and sometimes you lose.

Yeah, like I said, it's sometimes hard to tell from videos, especially if they don't quite reflect the experience you've had yourself.

I know one guy who raced his SLK 55 AMG versus a cousins Z4M. The Z4M weighs roughly the same as the CSL, with a little less power. Yet the owner of the SLK outran the Z4M.

So several factors come into play. I do think the DSG in the CLS helps tho', after all the Z4M only comes in manual and you have to be darn good at shifting to match the relatively high speed/smooth shifts you can experience with an automatic like the 7G in the SLK or the BMW CSL.

What?..... I think you wrong here. Didn't m3csl have the best 100-0 distance.
It actually is the benchmark for breaking in all the magazines I've seen.

I think the CSL has good stopping power, but just poor fade resistance. That has been a criticism of M cars for a while. I don't know if the new e60 M5 and e63 M6 are different, but Ms have been making due with single piston calipers for a while.

Just_me · 06-28-2006, 08:07 AM

The brakes on M cars arent bad, they are very good for everyday use. However if you take them to a track the brakes have a tendecy to fade after some laps.
Its common that BMW owners that use their cars on a track often replace the braks on their M cars.

but using them on the streets and for you ordinary driving, the brakes are very good.

Shinigami · 06-28-2006, 08:42 AM

Some owners and magazine reviewers have mentioned that whilst the CSL brakes (on a CSL or on the Z4M) are very good at stopping, they do run out of breath after a few good hard laps...

So far, replacing the SLK's pads or brakes has been a non-occurence for owners. Most have gained tens of thousands of miles on theirs (with track use as well as standard driving) and they have not had to change anything... My pads are still the original ones, and I've got 33,000km's on the car (and occasionally I do drive in a spirited manner).

I can't get any proper numbers on the CSL or SLK's 100-0 stopping distance (did a quick check in google, but nothing proper yet), but I do remember one review saying that the 55's brakes were very good, able to stop the car almost as well as the new composite brakes on the new Boxster, which is the best in it's class. Maybe if the SLK was as light as the Boxster, it would stop quicker? There is a "Nurburgring" setup available for the SLK with even larger brakes (composite ones) which might be even better... but not many people have that option as it only came out some months ago. I guess the CSL might also be one of the best in its relative class.

But the CSL and SLK are also very different cars

The CSL is definitely the "track" car, the SLK is just a cruiser
