• XTS adding twin-turbo V6
  • New engine makes 420 horsepower, 430 lb-ft
  • Pricing, exact release date still unknown

The 2014 Cadillac XTS will gain some horsepower in its second year on the market. Cadillac announced today that its flagship XTS sedan will add a twin-turbo V6 for the 2014 model year. The engine also will make its way into the new CTS sedan scheduled to debut at the New York Auto Show.

According to Cadillac, the twin-turbo V6 will join the XTS's options list this fall. The engine will produce 420 hp and 430 lb-ft of torque -- strong figures compared to rivals such as the Chrysler 300 and Lincoln MKS. It's also a big increase over today's 3.6-liter V6, which makes 300 hp and 264 lb-ft.

Though Cadillac hasn't confirmed it, the 420-hp XTS will certainly feature standard all-wheel drive. That's because a traditional front-wheel-drive layout will have trouble coping with that much power. All-wheel drive is optional on today's XTS. Models without it are among the most powerful front-wheel-drive cars ever made.

Cadillac has not announced any other information about the twin-turbo XTS, except to say that it will share the new powerplant with the upcoming CTS sedan. The smaller CTS offers standard rear-wheel drive and available all-wheel drive. It takes on rivals such as the BMW 3 and 5 Series, as well as the Mercedes C-Class and Audi's A4 and A6.

The XTS, meanwhile, is Cadillac's largest sedan. Priced around $45,000, the XTS replaced the aging DTS -- once called the Deville -- and the rear- or all-wheel-drive STS. The XTS is Cadillac's first model to offer its CUE infotainment system, which is accessed through a center-mounted touchscreen.

While we expect to see the new CTS in New York, Cadillac has not yet announced an exact on-sale date or pricing for its twin-turbo XTS. Performance is also uncertain, though the sedan will likely reach 60 mph in the low-5 second range. The sole transmission will probably be a 6-speed automatic, as on today's XTS.

What it means to you: The 2014 Cadillac XTS is adding a healthy dose of power for the new model year.
