    • Stock C218 Mercedes-AMG CLS63 S 4Matic vs. PTF BM3 OTS tuned F80 M3 S55 on the dragstrip

      The stock C218 CLS63 S with its 5.5 liter twin turbo M157 V8 is very stout despite the 4Matic system adding considerable weight. Having a ton of torque helps get it going and the ability to put that torque down even on street tires as this example did makes for a strong straightline performer.


      The F80 M3 is a much lighter car carrying roughly 1000 less pounds. The S55 motor when tuned is no slouch and this F80 has a PTF OTS Bootmod3 E30 tune. The rest of the mods are as follows:

      BM3 stage 2 OTS E30 map
      RK Tunes front mount intakes
      BMS Chargepipes
      Eurocharged Catless Downpipe
      MT Drag Radials

      The M3 is car number 39 and runs an 11.235 @ 124.58 compared to the CLS63 S with a 11.601 @ 121.90. A great result for a stock CLS63 S on street tires though and right where it should be.


      With a tune the CLS will regain the advantage. The M3 of course can upgrade its turbos. The CLS can do the same. It basically becomes a game of who spends more.

      The M3 certainly is doing well for bolt ons and showing what an efficient package it is. It ran a best of 11.197 @ 124.55:
