The 43 Series consists of a twin-turbo V6 rated close to 400 horsepower with 380 ish torque, depending on the application. Forced induction and smaller engines are all the rage because you get V8 power with small displacement. Many countries tax drivers based on engine size, but even the best V6 will suffer from slight turbo lag until boost is made.

So Mercedes-AMG is taking a page from the past. The new 53-series is based on an inline, or straight 6 engine. Instead of twin turbos, the future has arrived. One turbocharger is augmented by a 48-volt mild-hybrid system. The electric-powered kompressor can add 21 horsepower and 184 lb-ft of torque for a total of 429 hp and 384 lb-ft for both the new CLS53 and E 53 models. It also has the ability to provide energy when cruising, allowing the fuel injectors to run at idle.

Initially available on the 2019 CLS 53 and the E-Class coupe & cabrios, rumors about it will become the new base model engine in the S-Class and others. Combined system output is 429 horsepower and 384 lb-ft of torque, and it is sent to a 9-speed automatic. This power and transmission allows for a 0-60 mph time of 4.4 seconds in the CLS53 and E 53 Cabriolet, and 4.3 seconds in the E53 Coupe. One final benefit is that straight six engines have one of the best exhaust sounds in automotive history, so get ready for a straight-pipe symphony.
