Recently I had a chance to drive all the range topping cars during an offical AMG Drivers Lounge event in Affalterbach.

I am sharing this so we all can discuss my observations and I will be glad if owners could comment too.

I highly recommend this driving event, it is well worth the money.

The driving itself was done on public roads behind an instructor. Needles to say, the instructor isnt exactly hanging around.

The cars very very nice specs with Manufactur paints and leathers.

Overall, I must confess I am in love with the SL and the AMG GT coupe. Its funny how I seem to like what nobody likes (SL63) and I dont like what everybody is raving about (GT3 RS or GTS).

SL63
To me, this is the perfect combo. The burbly sound is such an event. I find this model to be the most balanced with perfect traction. You can pretty much boot it from any corner and the 4 matic takes it all. In that sense, it is so much fun.
I had lots of trust in this car.

SL63 E Performance
Curiously, I found this the most difficult to drive. Due to the torque figure, it is all over the place. It tends to fishtail even in straight line during full throttle and in corners it gets sideways quite often. These are little skids that stability control catches immediately, but you can feel it. They are always there and I found it difficult to drive it fast, find my rhytm with tje car because you are always watching out for the next slide instead of enjoying the drive.
When pulling out of a T junction with lots of traffic, the rear would always step out a bit and tires squeek. I think it has to do with the throttle calibration which isnt the greatest (its too sensitive, gives you too much too early).

AMG GT 63 E Performance Coupe
Very lovely experience, with the glass roof the interior feels elevated even further.
As an observation, I think I noticed a bit more stability that the SL so subjectively its a bit easier to drive fast that the SL; maybe because its stiffer overall?
What I found quite distubing in this model was the electric motor whine (very high pitched sound) in the interior. Anyone else has also experienced this? Maybe it was just this particular car.
In comfort mode, it seems to launch in electric only. I didnt have time to fiddle with the settings but it seems that you cant have the V8 fired up all the time in Comfort - is this true? If so, I would say its a bit of annoyance? I always had to switch to Sport to have the V8 running.

AMG GT 63 Pro
This was also very lovely, I noticed a sharper steering but overall not so much of a difference compared to the regular 63. To me, not worth the premium over the regular 63.

 

nice write up. can you give more details about AMG GT 63 Pro vs AMG GT 63?

 

Sure:
to be honest, differences are negligible and the overall perception of the car similar to a regular 63 (which is great, BTW) Looking at the specs, differences are more focused on cooling systems and aero, neither of which I have been able to perceive on the road (although we did reach speeds when the aero would have been deployed). I suppose it might be more noticable on the track, which has been Mercedes'interntion all along. The crazy colors and bucket seats can be had even for the regular 63.

I actually like the positionning of this car - how they made it comfy for daily use. I cannot imagine daily using a GT3 or GT3 RS. But I suppose I am the minority. Overall, I loved the Pro. I thought the steering was a bit more precise but I cannot find any mention of that being tweaked, so it might be just my imagination.
I would love a Pro just for sake of it/braggings rights but the pricing seems a bit much given the little it offers over the 63. If the price would be right however, that might change the game.

 

thanks buddy. much appreciated. it seems there is small difference, between GT 55 & GT 63. and even smaller between GT 63 & GT 63 Pro other than the cooling part.

All of them are great cars to choose from.

 

Interesting on the pricing: My 2025 GT63 came out to $214,340. Options: CCB, Aero-package, Carbon exterior package and interior with regular contoured seats, carbon steering wheel, front lift and pano roof. // Ordered a 2026 GT63 Pro with production date of 11/26 2025 came out to $217,270. Options: Front lift, pano roof, yellow seat belts, Carbon steering wheel, carbon interior and yellow stitching throughout interior. CCBs, aero-package, carbon exterior, bucket seats come standard on the Pro along with the mechanical updates. Both cars painted in Selenite Grey at no charge. If I had known that the price was so close I would have waited. All good.

 

In fact, they differ only in the front bumper and a few minor details on the underbody. They have the same power and tuning. They drive the same.

 

Ah! I am based in Europe where there is like 30k difference between the 2. In this case, PRO it is.

 

There's no difference if you build a GT63 with the same options in the configurator. I live in Europe too. ))

 

Agree on the minor tweaks but the PRO has 612 PS. EU spec that is.

 

This is only on paper. In reality, they both deliver:
POWER:
Mercedes-AMG GT 63 (C 192) 2023+
Factory Figures: 577 HP | 590 lb-ft
DYNO tested Stock: 625 HP | 681 lb-ft

 

the negligible increase in HP between 63 & the Pro can not be felt in street driving.

the slightly bigger HP gap between 992 Turbo & Turbo S still can't be felt in street driving.

 

actually the gt63 pro has higher output at 603 hp and 627 torque

 

The posted power is that yes, but the normal GT63 has been dyne's at 625hp per Renntech.

So would depend on what shenanigans they're pulling with the data. Would not surprise me at all that they just advertised the standard 63 at 577hp and pro at 603hp to give the people the impression they actually get more power with the pro. They don't want to potentially hurt sales for the more expensive car when the reality is you get some suspension updates, better cooling, and updated front bumper. Some of the upgrades the pro has standard can be had on the normal GT 63 as an upgrade.

But they advertise both having the same 0-60 times.

I don't know this as fact but it wouldn't surprise me if they actually have the exact same out put. And both are underrated from the factory #'s.

 

Yes I saw renntech showing 625 hp and 680 torque and you’re right it seems the 0-60 times are identical but the pro is faster 0-124 by half a second

 

0-124 1/2 second faster? What is the source for this?

124 is basically the 1/4 mile trap speed. So this source says the pro runs 1/2 second faster 1/4 mile with only 25 more HP?

I'd like to see the source and stats for that.... 1/2 second faster at those trap speeds would indicate more like 100-200 hp more. Which we know is not true.

If the standard runs 10.8-11.0 seconds, this puts the pro at 10.3-10.5? I've not seen any sources that say that, unless referring to the S E performance. And it does have 200 hp more. But it is 4-600 lbs heavier...

If 25 hp removes 1/2 a second on the 1/4 mile the rennntech piggy back on my GT63 that only adds 100 hp should have me down in the low 9's right? 2 seconds less. Which would also be a 0-60 in like 1.8-2.2 seconds. I dont think thats accurate, but would love to see what source youre citing.

sorry don’t know how to paste the sources but these are two of them
