2016 Cadillac CT6 Hybrid Debut Slated for 2015 Auto Shanghai, Mark Reuss Suggests

Reuss added: “we've really got to wait until we finish rounding out the [Cadillac CT6] portfolio," while a Caddy spokesperson commented: “we will add variants.” As a brief reminder, the CT6 sedan’s debut at the New York Show came with three powertrain options.

These are the entry-level, rear-wheel drive 2-liter turbocharged four-cylinder, joined by the AWD-enhanced 3.6L LGX naturally aspirated V6 and the 3-liter twin-turbo V6. The latter churns out a competitive 400 ponies and 400 lb-ft (542 Nm).

Rumor is the lineup will add a twin-turbocharged LT5 small-block V8 and a plug-in hybrid variant. There’s still no word on the force-fed LT5 motor, but the 2016 Cadillac CT6 Hybrid will materialize later this month.

Range estimates? We have been previously teased with an “industry-leading fuel economy of 70 mpg equivalent,” by global product development head Mark Reuss. In CT6-related news, Reuss told the previously mentioned publication that a V-Series model has been taken into consideration as well.

“The [GM Omega] architecture is certainly capable of doing it. The question is who's going to buy the CT6? What kind of person? And do we need a V-Series off of that is the question we haven't answered yet. It's certainly capable of doing it ... we've certainly thought about it,” the higher-up said.
