Cadillac will add power and torque to its XTS luxury sedan. Starting in August, the all-new Cadillac Twin Turbo V6 will go into production as an optional engine for the 2014 XTS.
In both the CTS and XTS product lines, the twin turbo will be the centerpiece of a new model offering called Vsport. The new Vsport is inspired by and slotted “underneath” Cadillac’s elite high-performance V-Series models. Vsport includes the best-performing technical elements inside the “regular” car line in a single model, headlined by Twin Turbo engine. The XTS Vsport model will be offered only in the up-level Premium and Platinum Collections as all-wheel drive and buyers are expected to pay $63,020 for the base four-door model, including destination and handling fees.
The new Cadillac Twin Turbo V6 is also a signature feature of the upcoming all-new 2014 CTS luxury performance sedan. In the XTS, the twin turbo will produce an 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 among luxury cars. The engine delivers 105 lb-ft more torque over the standard V-6 from1900 to 5600 rpm, providing seemingly endless torque for vehicle responsiveness.
The new Cadillac Twin Turbo is a comprehensive upgrade to the 3.6L dual overhead cam V6 that is standard in the XTS in the U.S. market. Almost every component is unique, including:
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 producing 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 quietness and smoothness.
The cylinder heads are also unique. 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.
Pricing for the 2014 XTS starts at $45,525, including destination fees, unchanged from 2013, with standard equipment including the 3.6L V6 engine that makes 306 hp, CUE, intelligent brake assist and Magnetic Ride Control. Three option packages are available: Luxury, Premium and Platinum Collections.
