TrueDelta Reviews the Real Gas Mileage of the Cadillac CTS

Cadillac CTS Real Gas Mileage: Cons
YearComment
With the 2011 528i, BMW pioneered the use of a turbocharged four-cylinder engine in a $60,000 midsize sedan on this side of the Atlantic. The point: fuel economy, specifically EPA ratings of 22 mpg city and 33 mpg highway even with all-wheel-drive (24/34 with RWD). Audi followed with an A6 2.0T good for 20/29 (25/33 with FWD) a year later. The new CTS takes the path blazed by the Germans, but much less effectively. Though the Cadillac weighs significantly less than the Audi or the BMW, its EPA ratings are lower, 19/28 (20/30 with RWD). The same is the case with the two 3.6-liter V6 engine options, even though unlike the turbo four they can be paired with an eight-speed (instead of a six-speed) automatic. The rear-drive-only Vsport barely evades the gas guzzler tax with ratings of 16/24. Even the 445-horsepower turbocharged 4.4-liter V8 in the BMW 550i does a bit better. In my real-world driving, the CTS's trip computer confirmed this shortcoming. Even considering that the outside temperature was near zero, post-warm-up averages that clustered around 18 were disappointing. Only by driving the car with a light foot could I nudge the suburban average over 20, and even then not much over. A 320-horsepower 3.0-liter 640i Grand Coupe tested a week earlier in similar conditions did at least one mpg better than the 272-horsepower, 2.0-liter Cadillac. And when I tested a 528i xDrive in slightly warmer temps it often managed 25 mpg (in an EcoPro Mode the Cadillac lacks). In one trip this BMW even touched 30. see full Cadillac CTS review

2007 4dr Sedan 306-horsepower 3.5L V6
5-speed shiftable automatic AWD		 My average for the life of the car is 21MPG. Not too bad for a car with this power and my lead foot. see full Infiniti G review
Infiniti G Real Gas Mileage: Cons
YearBody/PowertrainComment
2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic RWD		 Can live with it because of the performance, but wish the mileage was better and premium fuel was not required. see full Infiniti G review
2013 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 What the powertrain giveth, the fuel economy taketh away. Nissan's VQ engines just seem to be thirsty - if you commute in heavy traffic, especially for short trips, don't be surprised at 15.5-16 mpg tanks. I don't know what mostly-highway commuting would look like, but maybe 22-25 mpg depending on driving style. see full Infiniti G review
2010 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 To be honest, it is exactly what I expected, so no real beefs with it. That said, if you are looking for a car that gets better than 19 or so combined, this is not it. Decent freeway miles (24-27/g) but in city it is hard to beat 16/g. see full Infiniti G review

7-speed shiftable automatic AWD		 Fuel economy is poor - about 19 MPG average. see full Infiniti G review
2009 2dr Coupe 330-horsepower 3.7L V6
7-speed shiftable automatic RWD		 You do not buy a performance car and expect to get good gas mileage. At a 5 mpg or greater difference from my last car, it is taking some getting used too. see full Infiniti G review

7-speed shiftable automatic AWD		 average 18 in town 24 highway. see full Infiniti G review
2009 4dr Sedan 328-horsepower 3.7L V6
7-speed shiftable automatic AWD		 With such a large displaced engine and so much power you will find that you will have so-so mpg if you drive mainly in the city like I do. Especially if you are a "spirited" driver like I tend to be. I am averaging about 14-16mpg 95% city. On the highway its a different story. I have averaged up to 28mpg @ 78mph, I kind of wish I drove more on the highway. see full Infiniti G review
2008 4dr Sedan 306-horsepower 3.5L V6
6-speed manual RWD		 While not terrible, ~20mpg is by no means phenomenal. Relatively comparable cars get ~23-27mpg, but typically also have smaller engines which explains a good portion of the difference. see full Infiniti G review

5-speed shiftable automatic AWD		 Takes a lot of fuel... 14L/100km about. see full Infiniti G review
