Cadillac is aiming to trump its German rivals with the launch of the new CTS-V, the most powerful car ever made by the firm.

With a total power output of 640bhp, the new CTS-V soundly beats the BMW M5 and its 600bhp in its most powerful form and the 585bhp Mercedes-Benz E63 AMG. The new model is making its debut at the Detroit motor show.

Power comes from a supercharged 6.2-litre V8 engine, which is capable of pulling the CTS-V to 60mph in 3.7 seconds and allowing it to reach a top speed of 200mph. It’s coupled to an 8-speed automatic transmission.

Cadillac says it has increased torsional rigidity by up to 25 per cent compared with the standard CTS, while both the front and rear tracks have been widened. All in, the CTS-V weighs 1880kg, undercutting the BMW M5 by 65kg and putting it within 10kg of the Mercedes E63 AMG.

As on the new Corvette, both an electronic limited-slip differential and adjustable magnetic dampers are fitted to the rear-drive saloon. Two-piece, 390mm front rotors with 6-piston calipers sit behind forged 19-inch alloys to provide stopping power. Cadillac states the brakes “provide durability, consistency, and capability for track-day performance straight from the factory”.

Most exterior panels on the CTS-V are unique and an optional carbonfibre package compliments the standard carbonfibre bonnet, further improving aerodynamics and saving weight.

Inside, buyers can add Recaro seats to the cabin as well as a Performance Data Recorder, giving the ability to play back video and telemetry from track days.

The performance Cadillac will go on sale in the US next summer, but it’s doubtful the model will make its way to the UK as, like the standard CTS, it’s available in left-hand drive only.
