The new Cadillac CTS sedan will get better gas mileage this year, thanks to a newly adopted eight-speed automatic and thanks to the addition of a new turbocharged four-cylinder engine.
That base four-cylinder is shared with Cadillac's ATS, and here, it's rated at 272 horsepower--what a top-flight CTS made just a few years ago. In the rear-wheel-drive version of the 2014 CTS sedan, the 2.0-liter turbo four earns EPA ratings of 20 miles per gallon city, 30 miles per gallon highway, and 23 mpg combined. Adding optional all-wheel drive drops those numbers to 19/28 mpg, or 22 mpg combined. Both of these versions are outfitted with the six-speed automatic.
GM's workhorse, its 3.6-liter V-6, has a place in the mid-line CTS sedan. Rated at 321 horsepower and 275 pound-feet of torque, it earns an estimated 19/28 mpg with rear-wheel drive and the eight-speed automatic, or 18/26 mpg, or 21 mpg combined, with all-wheel drive and the six-speed automatic.
At the pinnacle of the CTS lineup--for now, at least--there's the Vsport, fitted with GM's new twin-turbo 3.6-liter V-6, and good for 420 horsepower and 430 pound-feet of torque. It's rear-drive only, paddle-shifted eight-speed automatic only, and rates 17/25 mpg in preliminary gas-mileage tests.
Active grille shutters are one of the many gas-saving technologies that have made their way into the CTS sedan, but there's no hybrid version in the works--though Cadillac has said it's mulling a diesel powertrain for some models it sells abroad.
