    4Matic M157 versus RWD M157 - Weistec tuned 2014 W212 E63 AMG S vs Renntech tuned 2013 W212 E63 AMG

    Here is the hot M157 on M157 action we have been waiting for! Finally a roll on race from an all wheel drive E63 AMG versus a rear wheel drive E63 AMG. Both cars of course have the M157 V8 twin turbo and both are tuned. The white 4Matic all wheel drive car is tuned by Weistec and features their upgraded turbochargers, downpipes, and trunk mounted ice cooler. The camera car features a Renntech tune as well as BMC airfilters. Its output is stated to be 624 wheel horsepower.

    Now, yes, one car features stock turbochargers and the other has upgraded turbochargers so that is obviously a huge variable. It is not a perfect or fair comparison but things rarely are perfect or fair in a race.

    Still a very interesting race to see however especially considering the result. The camera car gets maybe a slight jump opening up a lead on the 4Matic E63. This lead is held through a gear and then the 4Matic E63 starts to pull. The race ends as the turbo upgraded E63 starts to stretch its legs and pull past.

    What this shows is clearly the 4Matic car is making more power. However, it also shows that the weight penalty of the 4Matic system and its increased drivetrain losses are a large factor. If both cars had upgraded turbos the rear wheel drive vehicle would likely win this race. The 4Matic adds around 200 pounds for those wondering.

    Hopefully we see more runs like this to put the two E63 drivetrains in context. As of right now, it seems roll on races will favor rear wheel drive and going from a stop will favor all wheel drive. Nothing earth shattering that we did not already know.

    Excellent race and just like you said the E63 S is heavuer due to the all wheel drive system.


    I raced a tuned one from a roll with my SL63 a few days ago and beat it badly

    I'd expect a supercharged M156 to take a tuned M157 up top.

    Jeeze, the cars are quiet and composed that I had to watch the video twice to figure out when they actually got on it. Great for what it is, but it sure doesn't make for an entertaining race video!

    I thought it was pretty entertaining. There isn't huge drama with these cars but there isn't supposed to be.

    750 is a bit optimistic.

    Unfortunately this isn't the best angle but the C63 pulls.

    Yeah not the best, but it's the only one I have.
