    • Most powerful W205 C43 - AMR Performance pushes the 43 AMG M276 turbo V6 to 427 whp with RV3.1 tuning software

      AMR Performance just continues to push the M276 DELA 30 turbo V6 from Mercedes to new heights. This motor debuted as you know with C450 models but since then Mercedes revised the nomenclature and tuning with Mercedes-AMG 43 models. Check out what AMR Performance was able to get out of this W205 C43 AMG.


      They took it from roughly 300 wheel horsepower to 427 horsepower at the wheels with their latest RV3.1 software revision:

Those looking to really put down some power in a 1/4 mile.
      These are absolutely phenomenal gains and no other tuner is close.

      Keep in mind their older software revision back in 2016 on a C450 made 371 wheel horsepower and ran 12.3 @ 112 in the 1/4 mile. The result now should be easy 11's!

        Keep going and my dream of a c63 with 4-MATIC will come true. 4 months and my E63 arrives but I will always love the c63.

        Basically the same thing.

        The E at leat gives you the better interior/exterior.

        The C would maybe just weigh 200 pounds less. Maybe.

        The C interior is surely due an upgrade after what Ive seen in the new A class. This new A class AMG predator I think they call it looks amazing. That hot hatch may leave my e63s behind off the line and in the 1/4. What do you think. Surely it's too good as will embarrass C63 owners who may expect their car to be quicker ?

        No. I think it's understood the A45 is quick due to all wheel drive and a DCT but the C63 is the brute with the V8.

        Personally I'd just make sure my C63 was tuned and to avoid running from a stop... or get an E63. Click here to enlarge

        Almost 520 lb-ft to (all four?) wheels? This must fly off the line. Crazy power with just a tune!

        Considering how close they were before this revision, easily.
