Hi Guys,

Just wanted to ask everyone about something my MB Tech told me today.
We were talking about my car which is an E55 and how I handed a 300c SRT8 its *** from a stop the other day and he starts telling me that the motor in SRT8 and the motor in the 6.3 amg are almost the same. They share like 70%of the same parts and they were designed togther when Daimler owned chrysler and benz. I have never heard any of this before but this guy was very convincing. Both motors are 6.2 liters and he said the extra hp the benz has over the chrysler is all in the head and electronics which are different but the rest of the motor is the same.

Has anyone on here ever heard about this?
I find it hard to believe but the guy made sense. He said even the block dimension and internals are idetical.

I remember hearing that the 300c chassis is actually an Eclass chassis and the SRT8s tranny is an amg tranny but i never heard anything about the motor. It kinda makes sense though especially since the new Grandcherokee is an ML Chassis.

On a side note I have a jeep with the 4.7l V8 that I use for work and dont ask how but I blew the engine. Anyway I had to buy a factory rebuild form the dealer which cost me $4995.00 plus 2k install. The warranty had just expired. I was not happy But the truck was still worth $25k and i coulnt just scrap it so I bit the bullet. Anyway when I got the engine the service guy told me it was a mercedes motor. I had no idea about that either.

The two engines DO NOT share 70% of parts...utter manure.

Both engines are about as similar to each other as:


and

W211 BEAST

Yup, the only Dodge engine that's the same as an AMG engine is the engine in the Crossfire SRT6, it's the same as the SLK32's engine. And I'm not even 100% sure about that one.

slownrusty

Ok this one I buy...correct.

W211 BEAST

Oh, and to the OP, from what I remember the Charger and the 300 are built on the Mercedes W210 E class chassis, not the W211.

And on both of them, they ruined the chassis, somehow. My friend used to have a W210 E430, and I loved that car, I hated my Charger rental that I had for the past 2 weeks.

Busta Riles

They don't use the same suspension...big difference in ride.

You are correct about it being the 210 chassis.

The Crossfire is on the R170 SLK chassis too.

W211 BEAST

Im glad someone clarified that for me. I was gonna say that sould like bull. I guess I feel real good about the fact that the tech that told me that crap was the same tech working on my e55. LOL.I hate dealers.

Blownbenz

Sorry I meant the w210 e class chassis. I I knew that one was right. Im still shocked that my jeep had a benz 4.7 v8 though and im more shocked the damn thing blew itself apart at 50k miles. You gotta love american cars and there 36K miles warranty

slownrusty

Your jeep does NOT have a Benz 4.7L V8...you are killing me! That is a 100% Chrysler motor.

I had the same motor in my previous Jeep as well.

And if that's an AMG tranny, it's a ten year old design, but I doubt it since they, Dodge, touts their retarded "Autostick" 5-speed...

skratch77

swap the head and crank and you just made that srt8 a 6.3

the tech said the head was different and with a different crank you can get the same bore and stroke.

HeissRod

My Jeep SRT8 uses the W5A580 MB tranny.

skratch77

Heres a funny story,I went to the movies and this kid in a parking lot said how does it feel to have a car built by america.

I was like wtf are you talking about.He thought that the e55 was made by chrysler and used usa tech and they designed and built the engine LOL

I told him the only thing that happened is the other way around.The pos american cars got german engineering in them.

MB_Forever

The two engines are very different. Just look under the hood and compare the design and materials used.

after that's done you can throw on an AMG badge on the fender and trunk

citylightva

Man I could get the same bore and stroke out of a ton of motors...

I think I remember reading that the charger and the 300 chassis' were based on the w210 e class but the suspension components were made of stamped steel instead of aluminum- someone correct me if I am wrong. If true, that would change the whole handling feel and ride of the car.
