The Cadillac CT6 is (or was) a large sedan, with legitimate premium car credentials and performance sedan moves, at least before it’s imminent discontinuation was announced. The 2.0-liter was the new base engine for the model, beneath the 3.6-liter naturally aspirated and 3.0-liter twin-turbocharged V6s, and the, at one-point, upcoming twin-turbocharged V8.
Base Price: $58,095 As-Tested Price: $68,815
Highlights: The base engine in the CT6 is new — more specifically a new-generation turbocharged 2.0-liter four-cylinder that makes less power and torque than the outgoing model, but with a much broader mid-range. Peak power is a relatively modest 237 horsepower at 5,000 rpm and peak torque comes to 258 pound-feet, compared to nearly 300 before. The key difference is that peak twist is available between 1,500 – 4,000 rpm, compared to 3,000-4,500 before. Coupled with a 10-speed automatic gearbox, fuel economy comes to 24 mpg city, 34 highway, and 28 combined. Impressive for a 204-inch-long large car without any hybrid help.
Our Opinion: Well, this is awkward. This is a review of Cadillac’s flagship with a new 2.0-liter turbocharged engine. It comes only a few months after GM’s luxury brand announced a killer, 550 hp twin-turbo V8 engine for the upcoming CT6-V. Yet is also comes just a few weeks after GM announced that the Cadillac CT6 will cease production. So…
We are officially in a bind because this is a good car. At first, non-hybrid assisted four-cylinder power in a large family sedan sounds wholly inadequate, yet not once did I want for more power. I certainly wouldn’t have minded it, but the CT6 remained brisk and effortless to get up to speed. 237 horsepower isn’t much today, but the 10-speed automatic made proved a good companion. And 34 mpg highway fuel economy is pretty stellar.
Also, this CT6 possesses the same athleticism as the others, which is to say more than other cars in its class. A car of this size weighing less than two tons verges on miracle status these days and you could feel that lightness in its quick responses. Critically, the cabin still possessed the necessary quiet and civility of a flagship luxury sedan. Yes, a Mercedes S-Class is better, but the CT6 competed, and with a starting price a little more than half that of the Mercedes.
But this is all moot. The CT6 didn’t sell enough to make the Mary Barra cut. It’s been talked about for a while, but this is tangible proof that the automotive industry is in a real state of transition. We’ll see more change and we will not like some of it. As evidence, of the six cars GM is ending production, none are SUVs. The CT6 was the most car-enthusiast-friendly model to get the axe. And to lose it stings.
