2016 Cadillac CT6 Gets 400 HP Twin-Turbo V6

Cadillac’s upcoming full-size rear-wheel drive sedan will launch with a 3.0-liter twin-turbo V6.

Slated for production at General Motors’ Detroit-Hamtramck assembly facility, the CT6 will have 400 hp and 400 lb-ft of torque as part of a new engine family from the brand. That engine will offer cylinder deactivation, continuously variable all-wheel drive and three drive mode settings. Cadillac also said today that its new engine family will include both four- and six-cylinder diesel engines.

Along with the new oil burners, Cadillac will also have a new naturally aspirated 3.6-liter V6 that will slot into ATS and CTS and the CT6. The revamped naturally aspirated 3.6-liter V6 will come with an additional 14 hp and nine lb-ft of torque for a total of 335 hp and 284 lb-ft. Cadillac also said that it expects the revised engine to offer up to nine percent better fuel economy than the version powering current models. Those figures are based on burning regular fuel and are robust enough to credit the engine with being the highest-output naturally aspirated V6 per SAE certification.

Like the new CTS-V first shown during the 2014 L.A. Auto Show, the CT6 will use an eight-speed automatic transmission, although the version in this car will be a Hydramatic 8L45 instead of the 8L90 in the CTS-V.

The new 3.0-liter twin-turbo V6 will sit at the top of the CT6 engine line above the new naturally aspirated 3.6-liter V6 and a 2.0-liter turbocharged four-cylinder engine that will make up the base powertrain.

    Even though I just bought a car last year, I’m really itching to try — and even possible buy — a new Cadillac. I drove the ATS 2.0T two years ago and fell in love. Arrrrggghghhhhhh
