Cadillac has launched its most powerful model yet, the new CTS-V, which is scheduled to make its public debut at the Detroit motor show next month.

It is powered by a 6.2-litre, supercharged V8 engine that makes 640bhp, mated to an eight-speed automatic transmission. This gives the CTS-V an ability to sprint from 0-100kph in less than four seconds, while reaching a top speed of 322kph. At 640bhp, the Cadillac CTS-V is more powerful than both the BMW M5 and the Mercedes E63 AMG.

Torsional rigidity of the CTS-V is up 25 percent compared to the standard car, as per Cadillac, while both the front and rear tracks have been widened. All in, the CTS-V weighs 1,880kg. It gets both, an electronic limited-slip differential and adjustable magnetic dampers. Two-piece, 390mm front rotors with six-piston calipers sit behind forged 19-inch alloys to provide stopping power. Cadillac states that the brakes “provide durability, consistency, and capability for track-day performance straight from the factory”. Abundant usage of carbonfibre has helped improve aerodynamics and weight reduction.

The Caddilac CTS-V is expected to go on sale in global markets in mid-2015.
