Mercedes AMG Sport

Mercedes has already developed hardcore AMG versions of most of its models, but the company is now introducing an AMG Sport sub brand, which will line up against BMW's M Sport cars.

While not quite as hardcore as the fully-fledged AMG models, AMG Sport cars will feature unique design updates inside and out for a sportier feel. Engines will also be beefed up with extra power, while the chassis will gain a uniquely tuned setup and widened tracks, similar to full-fat AMG models, for a more engaging drive.

Petrol and diesel versions of AMG Sport models will be available and the C450 AMG Sport saloon will be one of the first models, scheduled to make its first public appearance later this year. This will slot in between the standard C400 and the fiery C63 AMG.

With a total of 367bhp from its 3.0-litre turbocharged V6 engine, the C450 AMG Sport is 34bhp up on the C400, but still over 100bhp behind the C63 AMG – which is expected to pack a snarling 4.0-litre twin-turbocharged V8 under the bonnet upon its launch next year.

Models expected to receive the AMG Sport treatment include the A, C, E and S-Class. GL, GLA, GLK and M-Class off-roaders will also see AMG Sport versions as will the BMW X6-rivalling M-Class Coupe, which is in the pipeline for a 2015 launch.

According to an insider this new range reflects customer interest, reports Autocar. A Mercedes insider told the automotive weekly: "We have identified growing demand for our more overtly sporting models, both in petrol and diesel guises. We intend to extend our range with a new line of models developed in partnership with AMG".
