What?! That's absurd (responding to the 0.02 second winner choice).

I've been around the big track at Willow more than a few times on track days and raced a season at the Streets (bikes never cars).

I'd like to see them compare either car against itself and keep the lap times for the same car within 0.02 seconds. I'd be impressed if they turned five laps and covered it by a 0.2 second spread.

I really struggled with the decision to go with the CCBs over the steel. I was worried about the initial bite of the CCBs around town when cold as some articles mention that for CCBs in general. I was pleasantly surprised when I picked up the car in Germany and found that they had plenty of bite and were very smooth. For the first day or two I kept throwing us into our seat belts a bit as the brakes are considerably better than any of the other vehicles I'm driving. Doing some heavy braking on the autobahn I found the brakes hit pretty hard even though they hadn't been used in miles - hauled me down from 130+ to whatever without really getting into them as I was still looking out for the comfort of my passengers.

The steels would have been fine I'm sure as mostly this will be my daily driver, but I know I will take it to the mountain on weekends where the brakes will see hard use on the down hill runs. At the end of the day I don't know that the CCBs will be any better than the steels, but their rep is that they're less resistant to fading so I said, what the heck and went with them. We'll see . . .

In tracking my GTS this summer (Steel) I noticed that they heat cycled very well, but still got mushy with enough repeated applications. I did run better fluid, and even put titanium backing plates on the front behind the pads to help with heat dissipation... I am looking forward to springtime, but I have to admit it is a bit disheartening to hear that the CCB's don't appear to help in any meaningful way where there are needed the most. One can possibly surmise that the E63 that was compared was most likely a car for the media to compare and may have had the crap beaten out of it by everyone? Either way, Im eager to actually see the video and don't really count the Cadillac in as a comparison to the Merc by virtue of its fit and finish and lack of AWD. I think we will have to wait till sometime next year for a proper compare between the AMG and the M.

Happy Holidays to All!

I thought at first it was the fluid so I changed it out to Castrol SRF and there was no difference in peddle feel between the stock fluid.
Trust me I bedded them in correctly and they were just cooked trying to slow the beast down, luckily I was on a nice road with no traffic to brake for.
Peddle feel did come back but it took a few more miles then you would think at a 50 mph cruise.
This made me nervous as I was heading to one of my favorite canyon roads... Maybe I should just slow down ?

Buttonwillow was one of my favorite tracks. Turned some 1:56s but usually in the 1:57s on my GSXR 750 back in the 2001 timeframe. Agree brakes are more heavily used there, and more representative of my mountain riding. Suspension also got a good workout and stock shocks were subject to fading mid way through an endurance race.

Doubtful that I'll ever do a track day at Buttonwillow with the car, but probably will at California Speedway.

In any case, looking forward to finding out in a month or so how it does on the mountain. ETA for the boat to Baltimore is Dec 22, then anticipating a few weeks to clear customs and VPC, etc. then I fly out to drive the car back to Cali.

I have lost the brakes more than a couple of times at the track.... Never on a Canyon Road. Might have to do not only the fluid change but more aggressive pads and SS brake lines to be aggressive on the canyons with this car.

The GT3 with the carbons do not fade at all! I beat the crap out of it last weekend on the canyons and they were like new... Wish the E63 brakes were that tough!

It's a shame they made the car so perfect in every way except for the brakes. I mean you can toss this sucker around on the up hill as if it were a Turbo S without skipping a beat but on the down hill you can feel every ounce of it's mass and it's feel in the breaking as the peddle feel starts to change...sad

I wonder if thats the case with the Steel brakes like I have too? I dunno, my brakes feel fine to me but I'm in flat Florida with no downhills or even that many curvy roads.

Whats 145K its an Edition 1--- try 135k LOL

Can we just see the stupid video already.

That 60 to 0 116 feet does not sound right, has this been documented with other reviews? I think maybe they got that wrong for whatever reason. Well, maybe not, lol.

E634Me

I didn't find anything current, but did find this article: http://www.motortrend.com/news/20-be...nces-recorded/

Number one best stopper was Corvette Stingray convertible at 90 ft.
Number five best was Porsche 918 Spyder at 94 ft.
====> Number six best was Cadillac CTS V at 98 ft.
Number ten best was Mercedes C63 AMG Black at 99 ft.
Number twenty best was Audi RS5 Coupe at 101 ft.

116 ft does seem out of character for the E63 and the class of cars in the comparison - you'd think it would have been closer to the 100 ft mark given the performance of many of the other cars.

How did they measure the braking distance? Drive past a line and stomp on the brake? I'm guessing they didn't wire up and fire a chalk marker to indicate start of braking. If they didn't have a way of positively indicating the start of braking, reaction time factors a lot into that given the 88 ft/s the car is traveling. 16 ft would be 0.18 seconds reaction time for example.

I know I was being more sarcastic since the car is so heavily priced.

I dont think Ive seen an edition 1 with that msrp so it must have some weird options (I know the carbon fiber gills are not on mine).

E634Me

I noticed that and thought it was a pretty highly priced car. Back when we were first trying to figure out what prices the options were going to be before the DOG was updated, one of the guys at that time said there were only like 5 cars scheduled to be delivered that were above $140 k and $145 or $146 was like the top price as I recall.

When I optioned my car out it was before the prices were available. I just picked what I wanted and hoped it wouldn't hurt too bad. Came in around $141 k.

So if indeed it was priced at $145 k, it is one of the most expensively optioned cars out there, top 1 or 2% anyway I bet.

And they fawked up the brakes on it

A 145 thousand Dollar car and it cannot even stop Me thinks they were just trying to make the Benz look bad because they know it's a far better car than the Caddy.

What's the 0-60, 1/4 mile, lateral g and figure 8 times from the test? Can anyone please share them?

Also, the 2016 CTS-V in the Car and Driver Lightening Lap is the current generation car, same as the 2017 tested here. MotorTrend tested a 2016 CTS-V before and they got the following numbers. Wondering if the CTS-V is that consistent or they just reused the number from the old Ignition episode.


60-0 - 99ft
0-60 - 3.8
1/4 mile - 11.9@122

Thanks for the link.

Autocar got 0-60 in 3.4 and 1/4 mile in 11.5 for the E63S, so the MotorTrend numbers seem about right. MotorTrend also tested the 10-speed ZL1 which has the same motor as the CTS-V, results were 0-60 in 3.5 and 1/4 mile in 11.5@125. Again the delta is roughly what you would expect comparing to the CTS-V that's heavier by about 200 lbs and down 10 horsepower and 20 lb-ft of torque.

I did expect more from the E63S though, given the new 9-speed gearbox and electronically controlled AWD system. Still if a RennTech tuned E63S only traps 129. The MotorTrend numbers again seem reasonable.

BTW, potential CTS-V buyer beware. Forget about the engine heatsoak, do some research on the GM 8L45 and 8L90 transmissions. Reports of CTS-V, Corvette and other models having problems with them. The number of complains from the CT6 owners are just horrible to read. I actually had a CT6 on order before they even hit dealer lots and very glad that I managed to walk away from that deal.

I read this and wonder if I should change my build order, which currently has CCB on the car. I figured the difference in the larger diameter rotors and the 4-piston rears would make an appreciable improvement for the CCB over the regular steal brakes. I didn't have any issues with my steal brakes on my '14 AMG wagon...

E634Me

There's also the lighter unsprung weight of the CCBs to consider. Would be interesting to drive two E63S back to back on the same road, one with, and one without CCBs.

The steels might be pretty cooked too after a Ronin-esque canyon run ;-)

Ya, I would not go by their stopping distance in the review, 116 ft is crazy, should not be that long.
