The 700 HP RennTech CLS63 AMG - /TUNED

Hartmut Feyhl left AMG after 15 years to start his own tuning company, RennTech, which is now one of the most respected AMG tuners in the world. His products range from simple software upgrades to full racing builds based on AMG street cars. We take his new, 700 horsepower CLS63 for a spin and establish a new benchmark for luxury sedans: must be able to do burnouts while moving at highway speeds.

"The giggle don't lie", pretty much sums it up. Nice car.

[@quysweat]

I have a CLS55 AMG and it leaves most cars on the freeway in the dust... I can't imagine how this 700HP RennTech AMG would be. This car is way over the top but I love it.

[@kaynec3079]

I love the sound of AMG's even stock they sound like they just want to go.

[@ntazanayamba3096]

amg is the best thing that has ever happened to man kind.

M series bro and also 911 series and AMG is the best that happened!!!

Nothing has changed in 7 years lol

[@erwinmonti5066]

WHAT A FANTASTIC VIDEO. RENNTECH IS A FIRST CLASS PLUS COMPANY. I BOUGHT MA FIRST MERCEDES 560 SIX LITER AMG WHEN HARTMOUT WAS IN NAPERVILLE ILL JUST OUTSIDE OF CHICAGO IN 1988. I WAS BORN IN GERMANY AS WAS HARTMOUT. HE IS BY VERY VERY FAR THE NICEST GUY I HAVE EVER MEET. HE IS DEFINITELY A MERCEDES TUNER. MY BEST TO YOU FROM CLEVELAND.....

[@davisdesigns1153]

As a 22 year old broke university graduate this video really resonates with me

[@lovebengtssonscarchannel2126]

friend of mine has a Kleemann tuned 820-850 hp (1400 nm) CLS 63 AMG fucking crazy car! he claims it easy does 370 km/h (230 mph) maby more. Love Mercedes, love AMG and love the guys who tune them Renntech, Kleemann, Carlsson, Brabus. just to name a few.

[@jazzarito]

This will forever be my favorite video on KZbin

[@lrgsr6009]

I worked for Mercedes for years and yes that is one badass car!

[@erusso2437]

That's one of the best sounding cars I've ever heard

[@shadman1911]

This car has that "boss look" to it like no other

[@CHIPZ711500]

4:12 THAT SOUND.....excuse me i must go change

[@Borderline5440]

I LOVE those wheels.

[@TheSmokingTire]

it's for aesthetics, as well as reduced lift at high speed. The parts are functional.

[@TheSmokingTire]

The Panamera Turbo S is a brilliant car, and if you need the AWD to get through your winters where you live, a great choice. But it's $174,000 (base) and $197,000 (as tested). The CLS63, even with the RennTech upgrades, is less than $140,000 and far more exciting to drive.

[@ctsperformance1755]

What a beautiful beautiful car...

[@TheSmokingTire]

When we tried to discuss filming with UGR, the short version is they were the first tuning company we spoke to who was actually rude to us. Everyone else has been very nice, regardless of what we've said about their cars.

[@DJDiggityDubstep]

Love the ignorance and jealousy that people have towards Mercedes without ever testing or owning one.

[@JSAFIXIT]

That's ok, my e55 got called the "grandpa car" A LOT.. until it outran the shit talkers, and never had any major issues other than chewing up rear tires at a high rate lol

[@0-60STYLE]

Eternity haters gonna hate

[@SBuckmann]

Great interview tied into a well done review. As always the camera work and the audio top notch...

[@OMGVision]

Love his e30 shirt at the beginning of the video!

[@sandyperalta3734]

now that is sick power love it..

[@TheEthalon]

I absolutely love this.. Forget mustangs, AMG are faster AND more luxurious

[@TheSmokingTire]

yeah, working on that for next season.

great work matt!

[@MLProductions.1]

neighbor has a 750whp cls63 amg. i thought its just wrapped in blue and bsically stock. but today before going out he asked me about my ls460 nd asked me what im pushing cuz it looks mean. i laughed and said its stock just bagged prolly pushing around 300whp. i asked him how much his merc is pushing and he told told me he dynod at 750whp. he told me his boy has ls460 pushing 500whp supercharged nd told me he can get me a hook up i told em ima prolly get rid of the ls for the new rc f. idk wtf he does. never working. up until 5am. prolly races or something. he has a bunch of mini bikes and a s2000 pushing 350whp. guys fucken crazy.

[@MLProductions.1]

eurosonly doubt he has a rich mom or dad since they both live with em nd they dont even speak english. i manage websites thats how i live. i doubt he does that. hes always tweaking shit in his garage. like dirt bikes mini bikes. im %90 sure he races. i dont live in a highclass hood. i live in the ghetto. cangoga. bu my street segregates from the rest nd we have a nice small neighborhood. but walk off the street nd its all ghetto. thankful? lmao. i wont stop till im in beverly hills.

[@simondoan9587]

drug dealer probably

[@thomaspersing4465]

Simon Doan Or maybe a day trader...

[@MLProductions.1]

Thomas Persing i doubt hes a drug dealer. he drinks nd smokes but ive blazed nd done coke with em. hes def not a dealer. hes always traveling. im sure he races. he sold his cls. Now he has a new f10 m5 and it looks crazy. he said so far with the tune he pushing abouts 600whp and he also has a ehaust setup. he wraps all his cars. i guess he likes to save the paint. i dont like the style of the bmw but it looks mean. he has red rims i havent seen em up close not sure what they are. And the cars wrapped in a gerying blueish with the spoiler wrapped black. Not my style but it looks good. the cla was fisrt wrapped matte blue and when he sold it it was wrapped matte orange.

[@MLProductions.1]

hes since gotten rid of the cls63 nd got a new f10 m5. mean af. changes colors everymonth nd rims ahahhaah. guys rich. he does race. he had the beamer saftey car in front of his house.

[@TheSmokingTire]

Mercedes's 7-speed MCT transmission is surprisingly good like that.

[@Wired1011]

AWESOME! I'm loving the Tuned series, keep up the great work.

[@jazzarito]

This car is currently participating in the Goldrush Rally. It now has 833hp and 980 torque.

[@MrDBSea]

700 HP in the usa with speed limit 75? or 80? miles...uh that hurts xD

[@RagingBad]

MrDBSea yes it does

[@RagingBad]

Genes are you even from here bro?

[@Outland9000]

Yeah but you can get to 75mph REALLY quickly.

[@lorrainesimser446]

With that much hp. I’ll be gone before the helicopter gets called

[@TheSmokingTire]

That to me says "street legal" but not "streetable." I've never driven, but ridden in a 1,500 HP muscle car, and it was a total handful that required 100% concentration at all times. Certainly not something I could actually enjoy beyond pulling into a gas station and telling people it had that much power.

[@Quik25c2]

This Sound is amazing!Thx Matt.

[@MegaMauserman]

Yeah I too love that rumble!

[@timothylokotkov9951]

next week we're driving a Switzer 1,100 horsepower GTR. I like AMS's products but Switzer has always been more than cooperative with our schedules and the car was extremely impressive.

[@trollprepper]

Matt, the reason we all dig your reviews so much... well the over-riding reason anyway.. is that you are a genuine car guy. You started doing this from passion, and you haven't lost any of that as you have progressed, and honed your craft. Been watching since the Garage 419 days.

[@jmatarazzo18]

It's a good idea to show us more often in futures clips the gauges while accelerating - 0-60, fill up 2nd gear may be.... Matt always speaks interesting things. I'm really get into it how explains everything padded with knowledge. Nice video by the way :) Keep doing this guys!

[@MrTaner76]

Hammer Renntech i love you thx for your makeing this

Plus these companies being featured are top in the business of modifying their specific brands. They know how to keep them on the road and be reliable. Keep doing these videos Drive, my favorite channel on youtube/tv.

[@TheSmokingTire]

The GTR's amazing straight line performance has much more to do with the transmission and differential than it does just power and weight. The transmission shifts much faster in the GTR than the Mercedes, and it can get a significantly better launch.

[@vinuv16]

I've seen almost all the videos of matt farah..he s a cool guy..always smiling..funny..i like his reviews..Thumsup..

[@IliescuBenyamin]

because, if you have that kind of power you can do what you only dreamed with your car. if you have 700 hp it doesn't mean that you use that power every day. it's just satisfying to know that you have that kind of power and that gaves you confidence that's why !

that was the most beautyest CLS ever made...
