Cadillac's 2016 CT6 luxury sedan will arrive as a lighter weight option to German competitors that's shorter than full-size and significantly longer than mid-size options.

Johan de Nysschen, Cadillac's president, gave a presentation about the CT6 to journalists on Jan. 26 about the vehicle, and the brand has released full specifications.

The CT6 will arrive with an overall length of 204 inches, a 122.4-inch wheel base, and a curb weight of less than 3,700 pounds. The Mercedes-Benz 2016 S-550 measures 206.5 inches in length with a 124.6-inch wheel base and 4,630-pound curb weight.

Cadillac has reduced weight by incorporating high-strength aluminum among the 13 different materials in the sedan to save nearly 200 pounds of weight in a move to improve fuel efficiency. It will offer a base model turbocharged 2.0L four-cylinder, 3.6L V-6 with all-wheel drive, and 3.0L twin-turbo V-6.

The CT6 will offer features such as active rear steer with a snow/ice mode that enhances stability, rear seat connectivity such as a screen integrated into the seat back and high-resolution 10.1-inch infotainment screen, a night vision system for pedestrian and animal detection, a rear camera mirror, and triggered video recording that Cadillac claims is an industry first.

The CT6 retails for $54,490 and will arrive at dealer lots in March.
