Engines produced from by Mercedes-Benz AMG are special for a number of reasons. They’re insanely powerful, they sound great, and all are hand-built by one technician. On the newest episode of The Downshift, host Jonny Lieberman travels to Affalterbach, Germany to not only tour the AMG facilities, but to build an engine, too.
Lieberman’s first impression of AMG’s digs is that it feels more like a tuner shop than a typical sprawling German assembly plant. There are about 40-50 mechanics including a young 20-year-old engine builder who acts as Lieberman’s instructor through the process. The engine is truly built by one man. And as Lieberman discovers, the facility, tools, and assembly process has been meticulous engineered to ensure these world class engines are none other than perfect.
In standard form, the M157 engine Lieberman builds will usually produce 518 hp and 516 lb-ft of torque. But add the AMG Performance Package, which was included in the super rare E63 AMG wagon we drove earlier this year, and the power figures get a bump to 550 hp and 590 lb-ft (some models get unique outputs like the GL63 AMG with 550 hp and 560 lb-ft). Despite some struggles with installing piston O-rings, Lieberman completes his engine build. Watch the video to find out what AMG does with the engine.
