    • Motortrend tests the 2012 W212 E63 AMG with the P30 Performance Package - 12.1@120 and 4347 pound curb weight

      We are finally starting to see more tests of M157 twin turbo V8 equipped E63 AMG's. MotorTrend got their hands on one with the P30 Performance Package which ups power to 550 horses. It comes at a price though and this E63 was not cheap with a final price of $131,045. We advise BenzBoost members to not get the Performance Package and instead get a tune that will give you more power for far less money from one of our vendors.

      12.1@120 certainly is not bad but we expected a little more out of the E63. The issue is the curb weight is higher than what we expected. The E63 is not lighter than the CLS63 AMG with its tested curb weight of 4347. It just slightly undercuts the F10 M5 which although heavier by virtue of its dual clutch transmission is able to keep pace with it. We believe we can definitively state the stock E63 AMG without the P30 package will be slightly slower than the F10 M5 and the P30 E63's will bridge that gap.

      We hope to see some F10 M5 and Performance Package E63 AMG comparisons from US magazines soon. For now, it appears the F10 M5 is not giving up anything and making more efficient use of its power. However, with a tune, the M157's are doing some real damage. It appears in that respect the Benz will have the advantage.

      • It's fast in straight lines.
      • The exhaust has a great growl.
      • It has $40,000 of equipment.
      • The $12,645 carbon ceramic brakes are good for just 2 less feet distance in 60-0 braking test.
      • It's too heavy and has body roll.
      • The steering and pedal feedbacks are poor.
      • The transmission isn't as fast as DCT's.

        13k for big brake kit that does the same thing as 400$ aftermarket pads lol. ouch. That thing is moving though 120 trap stock. These things tuned and bolted can prob hit 130 mark.

        Neat article. Thank you for posting. Two comments:

        About the 4347lbs curb weight, Where is this figure coming from?. The E63 is lighter than the 2012 CLS63 which has a curb weight of 4277lbs. On the AMG official website you will find that the E63 sits @ around 4080lbs

        This is implying that the E63 carries a DCT transmission, which is not correct. The E63 has the 7-speed MCT speedshift, which is rated @ a very high torque and very high horsepower. weve seen on the dyno how much torque this MCT can handle. I'm not sure where they got the part about the MCT not shifting fast. The MCT shifts @ 0.1 milaseconds between each gears. They dont call it Speedshift for nothingClick here to enlarge

        The SLS AMG carries a DCT with a carbon fiber shaft.

        MotorTrend.

        The AMG USA site has it listed at 4048. In actual tests it seems to be much heavier.

        He isn't implying the E63 can't handle it only that the competition which has DCT's shift faster... which they do.

        The weight difference is the result of having a long long option list. I also believe MB states the dry weight. Regarding to the transmission, I only wrote what was stated in the article.

        Any P31 package will be lighter than the non-PP and in either case, no extra options will weigh an additional 200-330lbs.

        No they dont!

        the curb weight that AMG provide is for a full weight car running with all controllers running fluids,%90 fuel tank, and a 75KG driver.

        Based on which test? has someone weighed it and found it to be 4347?

        The previous M156 E63 weighs around 4170 and this M157 weighs less :-) . Unless someone gives me proof otherwise, The M157 E63 weighs ~4048 and it is for that reason I believe it outreformed the M157 CLS runing with the same renntech tune at worse conditions and on street tires

        Exactly, I am going with Benz listed numbers. It only makes sense, although built on the same wheelbase the CLS is longer and a bit wider.

        MotorTrend's test of the F10 M5 said the curb weight was 4384.

        Wonder where MotorTrend is getting these numbers, are they actually putting them on a scale?

        Dude (SLS AMG) no offense at all, but sometimes you argue for nothing worthy. I apologize if i made a mistake regarding to the transmission part.

        http://germanboost.com/showthread.ph...and-Jaguar-XFR The MB's weight is 4252, i don't know if it was loaded with every option or not.

        MB states the curb weight. Don't know how they could miss it by this much though...

        It can be read that way but it can also be read as it isn't as fast as others with DCT's. I will edit for clarification.

        There was a European test that had the E63 heavier than the F10 M5 I believe...

        It's consistent, the E63 is heavier than what MB advertised it as. Every independent test has it in the 43XX range unfortunately:

        MotorTrend says two completely different things about the MCT, in the CLS63 test vs E63 test. Does MotorTrend realize it is the same transmission.

        From E63 test:
        The seven-speed automatic doesn't exactly bring lightning-quick shifts to the table -- not even in Sport+ or manual mode. Other dual-clutch units do it slightly better.
        From CLS63 test:
        Helping put all those ponies down to the pavement is AMG's Speedshift seven-speed transmission with its MCT (multi-clutch technology) system, which employs a start-up clutch in place of a conventional torque converter. Benz claims shifts come in little as 100 milliseconds when dialed up to the sharpest settings. You can further engage in the shifting experience through wonderfully placed and sized paddle shifters. We tried all four shift modes, including most notably the Sport+ setting, and with the exception of a few slight hiccups in the M paddle mode we experienced under hard up and downshifts, it's arguably the best-tuned automatic tranny in the business.

        Excellent point, that is a glaring inconsistency. Embarrassing for a publication like MotorTrend.
