Cadillac CT6 losing another engine option for 2020?

The engine line-up is down to three options.

Cadillac recently confirmed the CT6, the flagship sedan whose life cycle it recently extended, will no longer be available with a turbocharged, 2.0-liter four-cylinder engine starting with the 2020 model year. The company released the CT6's ordering guide which reveals another engine option is leaving the line-up.

The twin-turbocharged, 3.0-liter V6 will not return to the CT6's engine palette for 2020, according to website AutoVerdict. In the 2019 CT6, the six makes 404 horsepower at 5,700 rpm and 400 pound-feet of torque from 2,500 to 5,100 rpm. It spins the rear wheels through a 10-speed automatic transmission in its standard configuration, and it's available with all-wheel drive at an extra cost.

The plug-in hybrid model is dead, too, so the move leaves the 2020 CT6 with just three engine options. The entry-level unit is Cadillac's familiar 3.6-liter V6. It makes 335 horsepower at 6,800 rpm and 284 pound-feet of torque at 5,300 rpm. Buyers who want a faster sedan need to step up to a twin-turbocharged, 4.2-liter V8 rated at 500 horsepower. Both engines are bolted to a 10-speed automatic transmission.

The V8 is standard on the CT6 Platinum, still according to AutoVerdict. At the top of the range, the performance-tuned CT6-V carries on with a mighty, 550-horsepower version of the Blackwing V8.

Cadillac hasn't commented on the change, and it hasn't publicly released official information about the 2020 CT6 yet. If the report is accurate, we'll find out more details -- including pricing -- in the next few weeks.
