2014 Cadillac XTS Vsport

Cadillac is adding a new engine option to its 2014 XTS luxury sedan – an all-new Twin Turbo variant of its 3.6-litre V-6 that packs an SAE-certified 410 horsepower and 369 lb-ft of torque.

Its torque output is105 lb-ft greater than that of the standard V-6 from1900 to 5600 rpm, providing plenty of punch for rapid response.

The Twin Turbo V-6, which is said to be one of the most power-dense six-cylinder engines available in current luxury cars, will go into production as an option in August.

The new engine is also featured in the upcoming 2014 CTS luxury performance sedan.

In both the CTS and XTS, it will be the centerpiece of a new Vsport model line, slotted below Cadillac’s high-performance V-Series models.

Vsport includes the best-performing technical elements inside the "regular" car line in a single model, headlined by the Twin Turbo engine, the company explains.

The Twin Turbo V-6 incorporates more than the addition of a pair of turbochargers. Cadillac says 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 psi 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, featuring a high-tumble intake port design that helps produce a more-efficient burn when air is mixed with the direct-injected fuel and ignited in the combustion chamber.

In addition to the twin-turbo engine, the Vsport option includes upgraded 20-inch wheels and a unique grille. It will be offered only with the available up-level Premium and Platinum Collection option packages.
