Acura ILX Real Gas Mileage: Pros
Year	Comment
2016	High-revving largish fours aren't the fashionable route to fuel efficiency. But the 201-horsepower 2.4-liter engine when mated to an eight-speed dual clutch automated manual transmission (DCT) returns EPA ratings of 25 mpg city, 36 mpg highway--better than the 2013-2015 ILX managed with a 150-horsepower 2.0-liter engine. The Audi with its au courant 180-horsepower turbocharged 1.8-liter checks in a little lower, with 23/33. But the Acura isn't quite best-in-class. The Mercedes-Benz CLA250 manages 26/38. Notably, both the Audi and the Mercedes also have DCTs, though with "only" six and seven speeds, respectively. Then there are hybrids and diesels. The ILX used to be available as a hybrid. But the ILX Hybrid's fuel economy wasn't stellar (39/38) and its performance was so uncompetitive even compared to the Prius-based Lexus CT 200h (43/40) that Acura killed it after just two model years. The Audi A3 TDI, the segment's lone entrant with a diesel, rates 31/43. For a combination of performance and fuel economy, it's hard to beat. Except that as I write this Audi dealers can't sell them, pending an investigation into whether they violate EPA regulations. A final note on fuel economy: the TLX's EPA figures are only a single mpg lower than the ILX's. see full Acura ILX review

	Why doesn't Acura offer the larger four-cylinder engine with an automatic transmission? Likely because its fuel economy is already iffy with the stick. The EPA ratings are 22 MPG city, 31 highway. One benefit of turbochargers is that they enable lower rpm shifts and taller gearing. A Jetta GLI matches the Acura in the city, and does a couple MPG better on the highway. Not bad, but you'll find some much more powerful, much larger cars that score better than either of them. see full Acura ILX review

Cadillac DTS Real Gas Mileage: Pros

2009	4dr Sedan 275-horsepower 4.6L V8 4-speed automatic FWD	I bought this car almost specifically for my "road" car, for trips, but do occasionally use it around town. I don't know how the other reviewers are driving their cars but I get what I think is great mileage, mid-teens around town and 28-29mgh on trips/hwy at 75MPH. I do try to drive easy to enhance my mileage. see full Cadillac DTS review
2006	4dr Sedan 275-horsepower 4.6L V8 4-speed automatic FWD	Great Milage for the level of comfort, 25 plus on trips. see full Cadillac DTS review
2006	4dr Sedan 275-horsepower 4.6L V8 4-speed automatic FWD	Great on the highway. At 65 I get a consistant 25mpg. The city is an entirely different story. In stop and go city driving, the best I've ever gotten is 10mpg. The average is 8mpg. The EPA estimates 17 in the city. They are off their rocker. This car sucks gas in city driving. Stay away unless you have tons of money or own an oil refinery. see full Cadillac DTS review

Cadillac DTS Real Gas Mileage: Cons

2006	4dr Sedan 275-horsepower 4.6L V8 4-speed automatic FWD	Terrible in the city. 8 mpg on average. At least it takes regular. see full Cadillac DTS review
2006	4dr Sedan 275-horsepower 4.6L V8 4-speed automatic FWD	City gas mileage is pathetic. Since new I was lucky to get 10 mpg in the city, but in stop and go it's 8 mpg. When the car was newer, I took it to the dealer, and they checked everything out. I was told that it's a big V8. The Northstar engine is an embarrassment. see full Cadillac DTS review
