3.0L Twin-Turbo LGW V6 Engine To Power the 2016 Cadillac CT6

Thanks to a peak output “estimated at 400 horsepower (298 kW) and 400 lb-ft (543 Nm),” the 3.0L twin-turbo LGW V6 engine is one of the most power-dense six-cylinder motors in production. With 133 horsepower per liter, you’d better believe it.

To be showcased at the New York International Auto Show under the hood of the 2016 Cadillac CT6 flagship sedan, this tower-of-power is the descent of the 3.6-liter twin-turbo vee-six that’s animating the brutish 2016 Cadillac ATS-V.

The General Motors-owned brand is adamant that the LGW V6 is “the only six-cylinder engine to combine turbocharging with cylinder deactivation and stop/start technologies to conserve fuel.”

Is anybody interested that two cylinders can deactivate in order to save fuel?

Not quite. But how about this for a change: the LGW V6 is more potent than the BMW 740Li’s 3.0-liter twin-turbo V6 (315 HP and 105 HP/L) and even more potent than the Audi A7’s 3.0-liter supercharged V6 (310 hp and 103 HP/L).

Another juicy detail regarding the 3-liter twin-turbo LGW V6 engine from Cadillac is peak torque. Spread from 2,500 to 5,000 rpm, that’s a broad torque curve for a gasoline-powered mill.

“Torque is the pulling power of an engine and the new 3.0L Twin Turbo delivers it with confidence-inspiring smoothness and progression,” said Rich Bartlett, assistant chief engineer. “In fact, the potency of the torque across the rpm band is matched only by the satisfaction of the horsepower created as those revs climb quickly to 6,500 rpm.”

The press release below contains further info on the LGW V6 and a bonus: intel about the new-gen 3.6-liter V6 motor, dubbed the LGX V6, a lump that's rumored to be adopted by the 2016 Chevrolet Camaro as well.
