And that is exactly what the German auto giant is going to do. The M133 engine will be used on a new, upcoming model which is called the CLA-Class. The CLA-Class is said to be heavily based on a recent concept known as the Style Coupe Concept (top most image).
The CLA-Class will be based on a front wheel drive or an all wheel drive platform and it is sized just below the C-Class. The transmission that will be used on the A 45 AMG is a new seven speed dual clutch gearbox and it is possible that it will be used on the CLA-Class.
Obviously, the M133 engine will only be fitted to the highest grade of the CLA-Class. The base model will likely get a turbocharged four cylinder unit that makes around 210bhp.
The A 45 AMG is set to debut at the Geneva Motor Show in March next year and the CLA will be introduced shortly after that. Mercedes Benz intends to offer both models for sale within a few moths after their debut.
