We're only a couple of weeks away from the official reveal in New York of the all-new Cadillac CT6 flagship sedan. From the clues we've been able to uncover so far, GM's luxury division isn't holding back in any category; the CT6 won't be anything like your grandfather's Caddie. Cadillac fully intends to be a serious threat to German brands. But power and performance are crucial, and Cadillac knows this. So it has just released details of its new generation of V6 engines, led by an exclusive 3.0-liter twin-turbo with an estimated 400 hp and 400 lb-ft of torque.

It develops 133 hp per liter and is the only six-cylinder to combine turbocharging with cylinder deactivation and stop/start technologies in order to conserve fuel. When full power isn't being utilized, this engine will essentially run as a 2.0-liter V4. It'll be paired to an also all-new eight-speed automatic transmission. For the record, this engine's output is 27 percent greater than the BMW 740Li's 3.0-liter turbocharged inline-six (315 hp), and 29 percent more powerful than Audi's 3.0-liter supercharged V6 (310 hp), found in the A7. Like the turbo system found in the ATS-V, the new engine's turbochargers are lightweight.

They also feature low-inertia titanium-aluminide turbine wheels and a low-volume charger-air cooler, thus enabling optimal boost production and more immediate power delivery. Cadillac has also announced a new version of its naturally aspirated 3.6-liter V6, now featuring all-new structural and combustion elements that'll contribute to greater efficiency and performance. GM claims these are two of the most advanced V6 engines available anywhere, and we're anxious to see some performance specs. Regardless, welcome back to being awesome, Cadillac.
