Just last month, we were talking about Mercedes-Benz's plans to enhance its new C-Class range with an Audi S4 challenger named C450 AMG Sport and today, we have the first photos of the car spied without a single trace of camouflage.

The car caught by our man in Germany is the Estate version, but all what you see and read applies for the sedan model, and most probably, the upcoming coupe edition as well.

The C450 AMG Sport will slot between a new C400 model and the next C63 AMG. The C400 and C450 AMG Sport will share a 3.0-liter twin-turbocharged V6, with the former using the same 329hp (333PS) and 480Nm (354 lb-ft) version found in the new SL 400 roadster and the latter a more powerful variant with 362hp (367PS), according to sources.

This way, Mercedes evens out the horsepower differences between all three top C-Class models headed by the next C63 AMG sporting a new 4.0-liter bi-turbo that will start from around 450hp.

As you can see by the badges on the pre-production model, the C450 AMG Sport will be optionally available with Benz's 4MATIC all-wheel drive system in addition to a standard rear-wheel drive model.

On the cosmetic front, the AMG Sport edition features a subtle aero kit with new bumpers, the front decorated with a silver lip spoiler and the rear with a diffuser in the same color, side skirts, black mirrors, bespoke two-tone wheels and quad tips neatly integrated in the rear apron. The interior looks like it has a two-tone leather finish, while other features should include different trims, plus sports steering wheel and seats.

Chassis upgrades over the regular C-Class models will include improvements to the suspension and braking systems.

Look for the new C450 AMG Sport at the Paris Motor Show in October.

For the world premiere of the C-Class Estate (or T-Model, as it’s called in Germany) Mercedes-Benz didn’t choose a major auto show, instead it opted to use its own plant in Bremen, the core factory for C-Class assembly.

At the event, Mercedes-Benz demonstrated some of the C-Class Estate’s new features, including the Hands-Free Access system, which allows for opening and closing of the liftgate without touching it, and the folding of the rear seats at the touch of a button.

The video also features Thomas Weber, Daimler AG Member of the Board of Management, who talks about the Mercedes Connect Me services that allow users to connect to the vehicle from anywhere at any time and even retrieve the current fill level of the fuel tank online.
