2015 Mercedes-Benz S65 AMG Coupe tops halo lineup

Is the S63 AMG Coupe not enough for you? Here's your ride.

The S65 AMG Coupe is the S-class coupe range's new 12-cylinder crown. The AMG 6.0-liter twin-turbo V12 cranks out 621 hp and 738 lb-ft of torque. AMG boss Tobias Moers says some of his customers will ONLY buy V12s from him. This coupe is for them. It follows the S65 AMG and the SL 65 AMG. Mercedes likes to point out that no other automaker worldwide offers as large a portfolio of 12-cylinders.

The V12's horsepower and torque are good enough to propel the car to 60 mph in four seconds flat. Top speed is electronically limited to 186 mph. The 7G-Tronic trans offers controlled efficiency (including stop/start), sport and manual modes. We haven't driven the big coupe yet, but based on the other AMG Ss we've tried, we expected effortless and smooth power.

Mercedes' Magic Body Control suspension combines its Active Body Control and Road Surface Scan technologies, which include a “curve tilting” function for the first time in the U.S. It sees curves coming and allows the car to lean into corners -- like a motorcycle.

Steering is adjusted according to the suspension modes; lighter in comfort and stiffening in sport.

There are several visual elements separating the V12 from its stablemates. For example, you can choose between gray or red brake calipers, or spring for optional ceramic discs. The three-pointed star up front is finished in high-gloss chrome, as are the grille, air intakes, side air deflectors and front splitter. “V12 BITURBO” badges on the front fenders tell your neighbors what lurks under the hood.

We love S-class interiors and we expect this one will welcome you with terrific materials beautifully assembled. The sports seats have Designo AMG-exclusive napa leather with the diamond pattern. The dash has the other S-class' two-part wide-screen TFT display, and of course, everything is wrapped in lovely leather -- as we've grown to expect from the S-class line.

The car is loaded to the gills with equipment, including but not limited to a 360-degree camera, active-parking assist, high-zoot stereo system, Distronic cruise control, active-blind spot assist…you get the gist.

The car hits U.S. showrooms before the end of the year. Prices are still coming. Our guess? Somewhere in the $150,000 range.
