2019 Cadillac CT6 loses entry-level turbo four

The base engine is now a 3.6-liter V6.

Cadillac extended the CT6's life, but the model's cheapest configuration has been axed, according to a recent report.

The turbocharged, 2.0-liter four-cylinder engine that powered the entry-level CT6 is no longer available, enthusiast website Cadillac Society learned. The publication uncovered the change by examining documents sent by an anonymous dealer, and confirmed it by firing up the configurator on Cadillac's official website.

The cheapest CT6 now comes with a 3.6-liter V6 tuned to make 335 horsepower and 284 pound-feet of torque. It's priced at $56,490. The plug-in hybrid variant of the CT6 that was made in China has been dropped, too, so buyers are left with two additional engine options to choose from. First, a mid-range 3.0-liter V6 twin-turbocharged to 404 horsepower and 400 pound-feet of torque. Second, the V-Sport's mighty, 4.2-liter Blackwing V8 rated at 500 horsepower and 574 pound-feet of torque thanks to a pair of turbochargers.

Significantly, the 2.0-liter-powered CT6 was the only variant offered with rear-wheel drive. The three powertrains left are all-wheel drive-only. All three use a 10-speed automatic transmission.

Cadillac hasn't commented on the change. Cadillac Society notes two possible explanations. The entry-level engine might not have been popular enough among buyers to justify keeping around. Or, the publication points out that parent company General Motors is having a difficult time keeping up with demand for the engine, which is found in a wide array of models like Cadillac's own XT4, XT5, and XT6 crossovers in addition to the GMC Acadia.

We'll update this story if Cadillac releases a statement to explain the entry-level CT6's fate.
