    • Mercedes-AMG set to increase production four-cylinder power record to 400+ horsepower with next gen 45 AMG models

      This is interesting as not only is AMG's current M133 2.0 liter four-cylinder the production engine power king but AMG is kicking dust in Volkswagen's face with this motor on purpose. Why? Because Volkswagen poached the man responsible for designing the M133 engine in the first place.


      Volkswagen talked and talked about how they would take the crown from AMG only to not do anything as AMG increased output to 381 horsepower. Now, AMG will be pushing things even further and essentially matching Audi's 2.5 TFSI in output from less displacement.

      That does not mean the M133 will become a better modification platform but it does show that AMG does not intend to relinquish the four-cylinder crown and certainly not to Audi/VW.

      Cylinder head optimization is coming along with other changes to increase output. Dual-injection would take this motor to the next level in aftermarket tuning but it remains to be seen if AMG will change the fuel delivery.

      Regardless, expect over 400 horsepower with the next generation 45 AMG models.

        Day-um. Any reports on how these hold up at 100K miles?

        I haven't heard of many M133 problems but it's also not tuned as much as the bigger AMG motors from what I've seen.

        Coworker of mine DD's his AMG 45. He has about 60k miles right now since he travels to meet clients frequently and he hasn't had any issues, though his car has always been stock so I'm not sure how tuning the car would affect the equation.
