Overall winner at the first attempt - following on from its habitual success in motorsport, the Mercedes-AMG performance and sports car brand has now pulled off a similar victory in the area of production: the AMG hand-built engine production facility at the company's headquarters in Affalterbach is 2019 "Factory of the Year". With this coveted title, bestowed by A.T. Kearney, the specialist journal "Produktion" and SV Veranstaltungen, a jury of experts rewarded the work of the engine Manufaktur (hand-finishing section) in Affalterbach. The new AMG four-cylinder high-peformance engine M139 is built on a new production line here. With an output of up to 310 kW (421 hp), the completely newly developed 2.0-litre engine is the world's most powerful turbocharged four-cylinder in series production. On board the A-Class, CLA and CLA Shooting Brake compact models, it enables performance and driving dynamics on a par with high-calibre sports cars.
