We have been hearing for a while now that Mercedes was working on a new hybrid drivetrain for AMG models that would sit under the existing 63 models. The rumors indicated that the CLS might be the first car to receive a hybrid AMG model, with the E-Class coupe and convertible to follow. Now, AMG boss Tobias Moers has confirmed to Autocar that the hybrid CLS53 AMG is set to be revealed at the Detroit Auto Show in 2018. This model will be based on the all-new CLS, revealed this week at the 2017 LA Auto Show.

As the rumors indicated, the CLS 53 will use a 3.0-liter inline-six engine, which will be shared with future 43 models. We can only assume that this new inline-six is set to replace the 3.0-liter twin-turbo V6 that is currently used in 43 AMG Sport models. In the CLS 53, the inline-six will be paired with a 50kW electric motor to produce 429 hp. Moers also hinted that the E-Class would be the next car to receive a hybrid AMG version. Mercedes already builds the E-Class sedan and wagon as 63 models, but has never offered the coupe or convertible with an AMG version. Therefore, it seems likely that Moers is referring to the E-Class coupe and convertible when talking about new 53 models.

Even though the previous CLS 63 was much more powerful with 577 hp, the electric torque filling ability of the hybrid drivetrain should ensure that the performance is pretty close on this new model. This opens up space at the top of the range for the upcoming AMG GT four-door model. This range-topping sedan will likely pair the 4.0-liter twin-turbo V8 from the AMG GT with a hybrid motor to produce around 800 hp. We'll be excited to see the CLS 53 when it makes its debut in Detroit in January, and to see what other Mercedes models get the 53 AMG treatment.
