2017 Cadillac CT6 Driving Impressions


The 2.0-liter turbocharged model, 428 pounds lighter than the V6 models, is agile and light on its feet, taut and sometimes even too stiff, the closest thing to a sport sedan that CT6 offers. (Mercedes has their AMG and BMW their M, but there’s nothing there for the CT6.) The aluminum-and-steel chassis is rigid, and the electric steering is direct, with a pleasant heft and zesty response. But because the CT6 is long and wide, there’s too much car to feel truly sporty; the V6 with its heavier nose tends to understeer when pushed.

There’s an Active Chassis Package ($3300) including magnetic dampers with a firm grip on body motion, and rear-steer system to help the car turn in better. The rear wheels turn in the opposite direction, up to 3.5 degrees, helping the car rotate in low-speed turns, and providing stability in quick high-speed maneuvers.

However the magnetic dampers don’t offer as much range as the suspensions do on the S-Class and A8. The CT6 rides firm all the time, no matter which mode it’s in, from Tour to Sport. The Mercedes and Audi know when to soften up.

Of course, the Mercedes is about 1000 pounds heavier than the CT6 with the 2.0 engine. The heaviest CT6, the twin-turbo V6 with all-wheel drive, that 400 horsepower four-wheel-drive model, is still 225 pounds lighter than a BMW 7.

The turbocharged four-cylinder can hit sixty miles per hour from a standing start in 6.1 seconds, while the V6 can do it in 5.3 seconds. Power from the V6 is strong and smooth, equal to a V8.
