Without a fuel-sipping turbocharged four-cylinder, the CTS gets only middling fuel economy from its pair of V-6s: the 3.0-liter engine yields 18/27 mpg city/highway in rear-drive cars with automatic transmission, while the manual slashes that to 16/26 mpg. Somewhat unexpectedly, the larger 3.6-liter V-6 gets better fuel economy than the 3.0-liter when all-wheel drive enters the picture, scoring 18/27 mpg to the smaller engine's 18/26 mpg.
The Sport Wagon, with standard all-wheel drive and automatic transmission, gets 18/27 mpg with the 3.0-liter and 18/26 mpg with the 3.6-liter.
Conclusion
Compared to the latest from other brands in class, the 2013 Cadillac CTS V-6 engine lineup isn't as green as it could be.
