Amg63-

OEMs have been battling for years to see who can accelerate fastest, but for this one, we get a peek at two renowned tuners: Evotech and Renntech.

Read the rest on the MBWorld homepage. >>

found this thread in the general discussion section but seems like nobody came across it. I thought would be nice to post it here and hear some thoughts on this race.

Basically both tuned and the x5m smoked e63s. Hard to believe as it's Much heavier and less aerodynamic than the E with the same power

TMC M5

The E63 trapped 123.4mph in the 1/4 mile. I think that is a clear indication it was not making anywhere near the claimed 750hp.

Amg63-

123mph lol there are stock e63s doing that. R&t got a 123.1mph on their test of the e63s.


So basically a stock e63s is almost as fast as a tuned x5m with 750hp. LOL

My tuned E63s trapped 124mph at MIR a couple weeks ago.

I raced one of these a few months ago. He was running in the mid 12's steady all night. Didn't talk to him to see if he was tuned or not.

Amg63-

I don't know, for a car that says it's tuned to 750hp I don't think 123.4mph is proper for it at all. Maybe something is wrong with the tune they did who knows.

With a healthy running tune it should trap at least 125mph+ so the video doesn't add up.

im sure your car do better than 124, again seems a bit off.

Amg63-

how did the race end up?

this video shows the car in 11s tuned so doubt he was tuned.

I think if both are properly tuned the amg should have the clear advanage on the x5m as the E is the significantly lighter vehicle and has more torque.

tuned e63s do not trap 125+ on unprepped tarmac... track times and speeds are different than street... these moscow unlimited 1/4 and trap speeds are always slower than what you would see on a prepped drag strip.

Also, with the moscow unlimited events they usually are advertising crank HP, not WHP... 750 chp is about 600-630 whp, so tune/dp only e63

they both were slow in the 1/2 at 147-149mph.... my old e55 did 152 (never got my c63 or e63 to 1/2 mile event)

Amg63-

Then it appears according to this, that both were in fact tuned for the e63s to trap 123.4mph on the street. I guess its true that the X5M is the faster car. With the weight difference I wouldn't of thought the BMW would beat it. I guess this is what happens when you have too much tcu torque limitations.

gaspam

the bmw has a turbo upgrade, the e63 doesnt.... fastest tune/dp x5m is running 11.4 @ 121

internet videos are tricky

Amg63-

damn internet videos.

Gaspam take a look at the update in the cls vs e thread I started. Apparently the owner of the cls had a few things to say about that race.

I raced an E63S when I had an F85 X5M, and I kept up with him, but after 100 he started to pull on me. Both were stock.

Amg63-

sounds like the new m5 with xdrive will own the e63s from a dig.

PeterUbers

w212 likely ... perhaps not the w213

Amg63-

i mean only 0-60. Aren't w212 and 213 at about the same 0-60 of 3.4s?

TMC M5

Who knows how the new M5 is going to run. Is it going to have a DCT? If it does that may be with torque limitations in the TCU to help protect it from abuse. The current X5 M has a ZF auto and has a much higher peak torque figure than the current M5. So it is less of a concern for the engineers as far as the drivetrain shock on the transmission. So at this point everything is pure speculation.

Anotherone

I am not sure if he was trying 100% because stock for stock, the w212 is much faster stock and it doesn't weigh as much as the X5M. I was pushing and was always just a little behind and he just took off after 100mph.
