I have searched all over google, I looked everywhere on this forum and I cant seem to get the right answer for this car specific. I'm interested in buying a 2013 Mercedes AMG e63 Bi turbo, It comes with the p30 package which is quite interesting but I learned that it does not include the LSD. If this car does not come with a LSD WHAT KIND OF DIFFERENTIAL DOES THIS CAR HAVE? is it really a open differential in this expensive high performance car? The BMW m5 for 5 grand more comes with a LSD. If I do end up buying this car, I do plan on drag racing it. Let me include the link to the car i'm looking at.

Sorry guys, I just found out this car has the limited slip included I read the description box on the website. But still answer my question what kind of differential comes with the AMG if it did not have the limited slip

I have not inspected one personally, but without the LSD option, you guessed it. Open diff.
As hard as it is to believe, all the research ive done returns the same answer.

It's unbelievable the almighty E63 has open diff..
I had to buy a Quaife LSD even for my 354hp E55 because it didn't work properly under less-than-ideal conditions, the ESP was flashing all the time.
I can't imagine what is it like to drive a beast such as E63 with open diff.

the million dollar McLaren P1 has an open diff. Oh and it has no anti-roll bars either.

I never had trouble launching or sliding around corners in my "open diff" E55 and after installing the Quaife my 1/4mile times didn't even improve by .05s.

Have you ever driven in wet or snow?
Open diffs are useless when it comes to putting down the torque if one of the wheels loses traction. I don't believe you never had ESP flashing like crazy.. even launching W210 E55 properly is painful with open diff.

chiromikey

Yes but I'm not concerned about wet or snow with these cars. When ESP is flashing it's because I'm losing traction from both wheels, not just one. Whatever type of "open diff" these cars have, it's not like those of yesterday. Under most circumstances it still lays power down to both wheels. The poor launch capabilities of these cars is not because of the diff.

Jan AMG

Open diff is still an open diff. Only the electronics gets smarter.

I fully understand that but an old chevy 10 bolt open diff certainly won't spin both tires like ours does.

Jan AMG

Looks like Chevy 10 Bolt diffs were quite good and called "posi-traction" which is similar to a limited slip effect

Posi is chevy's name for lsd and came on 10 and 12 bolt, it's not their standard one legger open diff.
