Here are review new Cadillac XTS 2013 for release date and price. New Cadillac XTS ready to be marketed in 2013. This sedan was developed from the previous car, the Cadillac XTS 2012. The 2013 Cadillac XTS is designed on the largest variation, no surprise for the new flagship car at GM’s flagship brand. The Buick LaCrosse, and Saab’s latest 9-5 also use this chassis. The Regal uses the smallest version, as does the next-gen 2013 Chevrolet Malibu. As far as we know, however, the E2 platform cannot accommodate a V8 engine, so look for the 2013 Cadillac XTS to come with the top-line LaCrosse option, a 3.6-liter V6 with economy-boosting direct fuel injection. Only one transmission is likely too, the same 6-speed automatic used in most every other U.S.-market Epsilon-based model. The 2013 Cadillac XTS will be available in either front- or all-wheel-drive versions and come in two trims: base and Platinum. The XTS will be powered by a 3.6-liter direct injected V6 rated at 300 horsepower and 264 pound-feet of torque and mated to a six-speed automatic transmission. Estimated fuel economy for the XTS is a humdrum 17 mpg city and 28 mpg highway for the front-wheel-drive version and 17/27 mpg with all-wheel drive. Although the 2012 Cadillac XTS will not use the plug-in powertrain featured on the concept model, we do expect another, possibly more fuel-friendly setup to appear down the road. Cadillac says some grille shutters from the concept remain, though of course the plug-in hybrid powerplant doesn’t. While Cadillac won’t confirm a plug-in for the future, it’s clear the XTS eventually will get something under the hood as an option to the V-6. Cadillac hasn’t replicated the laser-etched leather seats of the 2010 Detroit show XTS Platinum concept, though it has replicated the perforated leather dash pattern. The perforations appear tight at the middle of the dash, then space out as your eyes progress to either outer side of the dash.
