TrueDelta Reviews the Real Gas Mileage of the Cadillac CTS

Cadillac CTS Real Gas Mileage: Cons
Year	Comment
	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

TrueDelta Reviews the Real Gas Mileage of the Chevrolet Tahoe / Suburban

Chevrolet Tahoe / Suburban Real Gas Mileage: Pros
Year	Comment
2015	You didn't expect to see fuel economy among the reasons to buy a Tahoe, did you? Of course, fuel economy remains well below that for most smaller, lighter vehicles. But General Motors has substantially improved the SUV's efficiency by adding variable valve timing, direct injection (fuel is injected under high pressure directly into the cylinder, rather than into the manifold), and cylinder deactivation to the 5.3-liter V8. EPA ratings improved from 15 city, 21 highway to 16/23 with 2WD and 16/22 with 4WD. I observed averages as high as 21 in the suburbs and 26 on the highway, quite impressive for an 80-inch-wide, 74-inch-tall, three-ton vehicle. Transitions between V4 and V8 operation are not perceptible, with the engine usually in the former mode when not accelerating, even at highway speeds. Ford took a different approach to improving fuel economy, replacing its 5.4-liter V8 with a turbocharged 3.5-liter V6. The resulting EPA ratings of 15 mpg city and 20 mpg highway are better than before, but aren't as good as the Tahoe's. My trip computer averages were similarly two to three mpg shy of those observed in the Tahoe. see full Chevrolet Tahoe / Suburban review
