Auto Verdict first reported on the engine’s disappearance this Saturday and noted the order guide only features two powerplants now. The first will be the entry-level engine, a 3.6-liter LGX V6 engine. The second will be the choice for those in search of more power, the 4.2-liter Blackwing V8 engine. Here, it’s detuned from the CT6-V levels to produce 500 horsepower and 533 pound-feet of torque.
The CT6-V gets a hotter Blackwing tune to produce 550 horsepower and 627 pound-feet of torque.
The 3.0-liter twin-turbo V6 bestowed drivers with 404 horsepower and 400 pound-feet of torque. With the engine’s demise from the CT6, it’s unclear where the engine may head next as the mill was only offered on Cadillac’s large sedan. The Cadillac CT4-V is a good guess, however. The luxury division will reveal both the CT4-V and CT5-V at an event on May 30th.
Without the twin-turbo V6, it makes for two engines gone from the CT6’s lineup. This month, we reported the 2.0-liter LSY turbocharged four-cylinder engine would also flee the coop. Cadillac never provided a reason for the end of 2.0-liter turbo-four availability.
In fact, the CT6 as a whole is in question. Cadillac’s “flagship” sedan was named as one of many passenger cars GM planned to cull from its portfolio. The car is currently built at the Detroit-Hamtramck assembly plant, which also handled Chevrolet Volt and Buick LaCrosse production. Both cars exited production earlier this year. GM plans to idle the plant in January 2020 while it builds Chevrolet Impala and Cadillac CT6 models a little while longer.
GM and Cadillac executives made things mysterious when they said GM is looking to relocate CT6 production to another U.S. plant. It could also be imported from China.
