The fantastic new Mercedes-Benz S-Class sedan adds a two-door companion this year—there’s no more CL-Class coupe, instead there’s the beautiful new S-Class Coupe. It was unveiled earlier this year in Geneva, but at the New York Auto Show it made its debut decked out in S63 AMG trim.

Start with the S63’s evocative new shape. It’s more commanding and elegant than the CL was, but it’s also about 140 pounds lighter thanks to aluminum body bits and lighter wheels and brakes. It’s still a cruiser at 4400 pounds.

The AMG signals are strong and clear from the outside. There’s a big twin-blade grille, a deep air splitter, and at the back, squared-off exhaust tips. Inside it’s pure luxury. The S-Class coupe shares the wraparound dash of the sedan, with exquisite details dominated by AMG logos—on the bucket seats, the armrest, the sport steering wheel, and the instrument cluster. It’s all swaddled in Nappa leather.

Power for the S63 comes from AMG’s 5.5-liter twin-turbo V-8. In the coupe it delivers a massive 585 horsepower--the most power we've seen from the engine yet. The engine is paired with AMG’s seven-speed automatic and will rocket it to 60 mph in under 3.9 seconds. Top speed is limited to 186 mph.

Like the S63 AMG sedan, the Coupe is a 4MATIC, which means rear-biased all-wheel drive. An air suspension is standard, and the suspension gets more structure at the rear end for better stiffness.

Pricing hasn’t been confirmed, but if you’re not prepared to pay more than $150,000, you might want to close your eyes and forget you ever saw it.

Stay tuned to Motor Authority for a first drive of the S63 AMG coupe later this year.
