Well there isn't really a press release, but details for the LF3's application in the XTS are now available.
The LF3 will be available on Premium and Platinum AWD models, generating 410 HP/369 lb-ft of torque from 1900-5600 RPM.
XTS models equipped with the LF3 will receive a unique front grille as well as Twin Turbo badging on the rear decklid.
XTS will also offer a revised rear seat armrest with wood trim, rear seat audio controls, and rear retractable sunshade controls.
The new Cadillac Twin-Turbo 3.6L V-6 is available in the XTS, delivering SAE-certified 410 horsepower (306 kW) and 369 lb.-ft. of torque (500 Nm), making it one of the most power-dense six-cylinder engines in the segment. A pair of smaller turbochargers and an efficient charge air cooler help provide more immediate power delivery, while peak torque is sustained over a broad range – 1,900 to 5,600 rpm – for a confident feeling of power in almost all driving conditions, such as accelerating or overtaking traffic on the highway.
The twin-turbo engine is a comprehensive upgrade on the 60-degree, 3.6L DOHC V-6 that is offered as the standard engine in the XTS. However, almost every component is unique. New features include:
- All-new cylinder block casting
- Strengthened connecting rods
- Machined, domed aluminum pistons with top steel ring carrier for greater strength
- 10.2:1 compression ratio
- Patented, integrated charge air cooler system with low-volume air ducts
- Two turbochargers produce more than 12 pounds of boost (80 kPa)
- Vacuum-actuated wastegates with electronic control valves
- All-new direct injection fuel system
- Tuned air inlet and outlet resonators, aluminum cam covers and other features that contribute to exceptional quietness and smoothness.
The cylinder heads are also unique to the Cadillac Twin-Turbo. They feature a high-tumble intake port design that enhances the motion of the air charge for a more-efficient burn when it is mixed with the direct-injected fuel and ignited in the combustion chamber.
