(April 19, 2011) DETROIT — Cadillac’s CTS luxury sport sedan, coupe and wagon will add an upgraded V-6 engine, new grille and new Touring Package edition for the 2012 model year.

The new 3.6-liter V-6 will use a lighter, more efficient design to give customers more power at the same fuel economy as the current 3.6-liter V-6. The new engine delivers an SAE-certified 318 horsepower and 275 lb.-ft. of torque, compared to the current engine’s 304 horsepower and 273 lb.-ft. of torque.

The EPA fuel economy label will remain 18 city/27 highway mpg.

The CTS’s shield-shaped front grille has been redesigned with new premium finishes that highlight the intricacies of a new frame and mesh combination. The Wreath & Crest logo also has sharper colors and raised ridges between the colors, giving it a three-dimensional quality.

The changes will be carried in all three CTS models — CTS Sport Sedan, Sport Wagon and Coupe. The 2012 models will arrive at dealerships in late summer. Pricing will be announced closer to the start of production.

“CTS has established itself as a world-class line of luxury sports cars, but to remain on top, we have to continually make improvements,” said Don Butler, vice president of Cadillac marketing. “The changes for the 2012 model year give customers a fresh take on the CTS’s bold front grille and provide enhanced driving performance without sacrificing fuel economy.”
