Editor's note: An earlier version of this story incorrectly characterized the horsepower rating in the 2014 Cadillac XTS' twin-turbo V-6 engine.
DETROIT -- Cadillac is adding a new 410-hp, twin-turbo 3.6-liter V-6 engine as an option on the XTS sedan for 2014.
General Motors unveiled the engine back in March, confirming that it will be an option on the new-for-2014 Cadillac CTS, and recent Cadillac press materials confirm that the engine option will be expanded to the XTS.
The all-aluminum engine makes use of direct-injection technology and is the highest-output V-6 in GM history. Its peak horsepower comes at 5,750 rpm and it reaches peak torque of 430 lb-ft at 3,500 rpm. Unlike the CTS sedan's eight-speed transmission, the twin-turbo V-6 on the XTS will be mated to a six-speed automatic transmission.
A 3.6-liter V-6 remains the standard powerplant on the XTS. Nineteen-inch wheels and Brembo front brakes are also standard.
For 2014, the XTS will also add optional features such as automatic parking assist and electric power steering on front-wheel-drive models, automatic-dimming headlamps, rear-seat entertainment system with twin DVD screens that fold out of the backs of the front seats and front passenger-seat memory. Interior upgrades include a revised rear-seat armrest with wood trim, radio and sunroof sunshade controls.
The XTS will continue to be offered in standard, luxury, premium and platinum trims. Cadillac would not confirm pricing for 2014, but the 2013 base model carries a $44,995 price tag after shipping charges.
