Renntech vs AMG: 1/4 Mile DRAG RACE Tuned CLS 550 vs CLS 63 AMG Bradenton Speedway Raceway

[@Ysl_kidd]

Old man in the 63 needs to wake up.. give me the cls63 I’ll show what to do with it

[@BrianTindall-fl5hc]

Not. This old man just needs some free time behind the wheel at the strip.

[@clevelandaeromotive]

@@BrianTindall-fl5hc totally agree. You had just got your car. You were still getting dialed in to it. I think there are a lot of AMG owners watching this that are a little butt-hurt that getting a RENNtech ECU tune can deliver virtually the same acceleration performance as an AMG.

[@Hi.Al.]

Amg has additional cooling, just tunning ecu isn't suficient.

[@BrianTindall-fl5hc]

I had an awesome time doing this video with Stephan. Looking forward to a rematch in cooler weather.

[@clevelandaeromotive]

Ohhh! OH! Did I hear “rematch”?? Just let me know! XD

[@hEXordo]

Learn to launch first

[@tredeuce2]

The 550 did well but the AMG definitely did not perform up to its potential.

[@clevelandaeromotive]

I think the real race was race 1. My camera guy even said, “C’mon man! 2 out of 3!” I was, like, “Nah. That was a perfect demonstration of RENNtech vs. AMG.” But I did 2/3 anyway.

[@talkditingsdem5799]

1. The AMG isn't the p30 performance package. So it's just 518 horsepower. Weighting 4,300+ lbs without the driver. 2. The AMG is rwd so it shows it true potential from a roll. 3. The heat, humidity and altitude affects it's performance. 4. The guy driving the AMG do not know how to launch his car (he can't drive).

[@clevelandaeromotive]

@@talkditingsdem5799 we did discus how he was new to an AMG beast with only RWD at the end of the video. He just needs to dial himself in to his new car is all. Correct on all other counts. The D-Alt affected both our cars equally.

[@iceapella15]

This might be a wee bit off topic for this video, but today in my CLS63 AMG I schooled a Tesla driver who was like, WTF!!

[@snowbell01]

Thanks for making this video! Some good races, if you can ever line your car up with a awd 63 that'd be sweet to see how it compares.

[@clevelandaeromotive]

I had an CLS 63 sAMG all lined up, then, it got totaled. Thus the delay on producing the video. But yes, perhaps a 4-Matic AMG at some point.

[@LuisTorres-bv3kf]

Great video! The comparison nobody else has done, would be interested in seeing the 1/8 times as well.

Noted!

[@larryhand5892]

Was looking forward to this. It would have been interesting for you to switch cars. This fellows reaction times killed him. The first race would be the best read for the difference between the cars. A better analysis would be for your best time in both cars. The Renntech tune certainly seems worth the money.

[@BrianTindall-fl5hc]

Yes my reaction times sucked. Not having the car for very long and a hectic work schedule didn't leave much time to get some launches under my belt. Too much boost created wheel hop, too little and it lagged bad.

What stage

[@S.Madman]

Nice races, always wanted to see to see this. I would wait until late fall or winter here in FL. This summer is not nice to our turbocharged V8's.

[@clevelandaeromotive]

True that. I imagine, with density altitudes closer to actual field elevation, the times would have been much closer to 12:00 sec. We might do a rematch in January, once Brian knows his AMG better. Thanks for commenting!

[@billpowell9624]

Would you be kind enough to send me the link about your process of finding your CLS and what to look for? Especially the engine nomenclature - M???. I am pretty much done with AMG's. Fast, but so much more expensive for service. Your CLS description and my age appear to be a good match. Thank you and am enjoying your channel. Bill in Tallahassee

[@clevelandaeromotive]

Ummmm, I just looked for a very low mile CLS with the V8 biturbo, M278 engine. I looked for 2014 or later to avoid any "teething" problems.

[@johnblack6340]

Great demonstration renntech tune make a big difference

[@Cucuy_HMMWV]

No the guy in the AMG reaction time is trash. 😂

[@QueButter]

Nah even with bad reaction time the Amg would still beat a 550. This video just sold me. I got beat multiple times in my gls 550 by 63’s. Now although they were sedans the gapping was disrespectful, and I regularly beat up on 53, 43, infinities, certain bmws(lol) etc i need that extra speed.

[@clevelandaeromotive]

I think Race 1 was everything a well maintained CLS 63 AMG and/or a RENNtech ECU tuned 550 can do with a DA of 1550'. Some sluggish R/T's on both of our parts that race. AMG:.12.46 1/4 mile - .707 R/T = 11.75 sec. Assuming a low DA (close to sea level) and a professional class R/T (sub 0.1 sec) all the time, upper 11's could very well be expected from a CLS 63 AMG.

Really? Had the car for 2 months and very little time behind the wheel.
