If your races are not on a road course, but in straight line, avoid GT3 and GT3RS. Porsche makes the 991 Turbo S and the GT2RS, tunes for these two are available too.

You can have a 509 or 600hp c63 and I know it can't put that power to the ground..it will just burn tires and do around 11.3-11.7 1/4 mile times..a 2018 GT 3 will do 10.7-11.1 1/4 times

i put 295 MPS4S on the car and the tires hold up very well.

A tune does relatively little for a normally aspirated motor. These cars are designed for corners (preferably those on a race track). Saying the handling of a C63 doesn’t compare to an RS is beyond an understatement. They’re not just in another league - they’re not even playing the same sport...

I figured...when i had the ISF it was the same story. NA barely pulls power from tunes.

Have you considered an AMG GTR? Seems like that would be a good fit for you (power wise). Not sure about practicality wise.

FYI - E63 is being updated / face lifted...so keep an eye out on a new one in about a year or a bit more. The biggest update is the infotainment (which I think is worth waiting for).

Even if a gt3 raced a gts the gt4 would lose on pulling power. Although the gt3 has 25 more hp, it's down 80tq which makes a big difference. But being in the right rpm range helps but still both have a good top speed numbers. The gts loses in the sound department as well as track car stays. I cant speak for the merc bit wanted to let people know about gt3 vs gts. 2015 vs 2018 models. This is first hand knowledge.

sorry...i didnt quite understand...were you talking about the gts the whole time or 3 different cars? I see gts, gt3 and gt4...not trying to be a dick.

Mercedes-AMG makes great cars, it is unfair to compare anything other than AMG GTR with a GT from a performance POV.

BHP and torque also require a more important calculation, power to weight ratio. Not going into exact numbers, there is at least 200kg difference of 1400kg+ (991 GT Cars) vs 1600kg+ (W205 C63s) which changes the whole equation.

Torque is always a misleading indicator.

I actually rate Mercedes build quality on par with Audi and BMW, definitely not comparable with Porsche.

All the FR AMGs are meant to be driven sideways with the tail hanging out or always feeling like it's kicking out, it's never going to grip and corner like a GT car.

Thanks!
King,
The issue is with the test drive, you may not see the full potential on the GT3/RS. Car does not really come alive until at least 5-6 K RPM range. See if you can get another ride/drive in a GT3/RS to experience the power range better, perhaps you will change your mind.

Had a C63 and and a GT3 (not RS) at the same time and it never occured to me to compare the two. Don't need a Turbo S or a GT2RS to out drag a tuned C63, I bet a tuned GTS will do nicely. But neither will handle like an RS and after 5 corners or turns, neither will see the tail light of an RS.

You probably recognize you’re going to get a heavy perspective towards a GT3/RS on this forum. It’s been my experience that it can take time and a whole lot cash spent on cars before reaching the point of a GT3/RS purchase. It’s an expensive car and one that is very specialized. Arguably, it’s also the most appealing form an appearance standpoint too. The lower stance and aero just fits perfectly and it is all functional. I have owned Lambo’s, most recently Huracan LP610-4, Porsche 911 turbo and many others. Now I have an RS. It fits my needs brilliantly and is without question an amazing driving experience. It may not be the right time for your needs but I assure you when that time comes you won’t be dissatisfied. Good luck!

Well spoken.

What is it like to own a Huracan LP610-4 / Performante? I hear good things about ALA.

I owned C63s edition 1 coupe, a Turbo S, 991.2 GT3 and RS.

I do exhaust on all my vehicles as it’s a must for me. So that impacts my opinion and feedback of the vehicles.

My personal experience was the Mercedes sounded good, had lots of power yet was a little too “computerized” for my liking.

The turbo S was chipped and incredibly fast. For raw speed and power its hard to beat. There really isn’t much faster in a straight line.

The GT3 was manual, engaging and fun. As previously mentioned the car really lives in the upper rev range. The sound is amazing. My first GT car didn’t disappoint.

The RS was hands down the the winner for me; I love the looks, the rawness and the PDK really blew my mind on how different the manual 3 and RS drove. I’m the first to admit that I’m nowhere a highly trained or skilled driver, yet competent. The PDK really let me drive the car at a higher level, and I was surprised that I didn’t miss the manual.

Got a speedster on the way, looking forward to see how it compares....

At the end of the day 911’s are purpose built sports cars. A C class isn’t. Not to say they aren’t a great bang for the buck, yet the GT cars you’re comparing the C63 to are different level.

My input is only worth what your paying for it lol.

I did not have a Performonte. Nonetheless, I can share my perspective on ownership. It comes with an extreme amount of attention. There is no escaping that part of the experience. It’s a solid performer and the AWD plus DCT pair well. Also had 2013 LP550-2 so can attest the Huracan was a big leap forward. The car is NEVER mistaken for anything other than what it is. Lambo has that perfected. If one has the means, it’s worth the price of admission. I had a poster of the Countach as a kid and was fortunate through hard work to turn a dream to reality. IMHO, sometimes Lambo owners get a bad rap, e.g. more concerned about being seen than actually enjoying what the car can do. To each their own...it’s still a great car.
