During the broadcast of the 2015 Oscars, the upcoming Cadillac CT6 got an unexpected reveal in a commercial (see the video below), but the details surrounding the car are still sketchy. The only real information that Caddy has passed on is that it’ll be the lightest car in its class. Now, thanks to a Q&A session the folks at Jalopnik had with Cadillac boss, Johan de Nysschen, we’ve learned that the new luxury flagship may include a twin-turbo V-8.
The Cadillac executive stopped short of confirming this powerplant, but when queried about how the model will stack up against the Mercedes S550 and the BMW 750, he said its “lightweight body structure allows us to achieve formidable performance even with a twin-turbo V6. Imagine how this car would perform with a twin-turbo V8.” As if that wasn’t confirmation enough, the candid de Nysschen then said the CT6 will feature “a very wide mix of engines, starting with a two-liter turbo, up to, eventually, a high-performance advanced V8 turbo.”
Those two statements in themselves all but confirm a twin-turbo V-8, but they also show that the CT6’s progression will happen slowly. From the looks of things, the model will likely start life with the base 2.0-liter and 3.6-liter twin-turbo, then eventually we’ll see a V-Series model hit the market with a twin-boosted V-8.
The powerplant of choice remains unknown, but it’ll likely be exclusive to the Cadillac range, as there is not much room in the rest of GM’s lineups for this type of engine. In terms of power output, I expect to see this engine match or beat the 577-pony output of the S63 AMG 4MATIC, putting it above the 540-horsepower output of the Alpina B7 too.
For now this is all just talk, but given de Nysschen can hang on to his job at Cadillac long enough, I fully expect him to follow through with his plans. Then it would just be a matter of whether or not high-end BMW and Mercedes buyers would actually consider a Cadillac or not. Only time will tell.
