Cadillac DTS Real Gas Mileage: Pros
YearBody/PowertrainComment
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

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
 

TrueDelta Reviews the Real Gas Mileage of the Lexus LS

Lexus LS Real Gas Mileage: Cons
YearComment
Nearly everyone except Toyota has been transitioning to boosted engines for fuel efficiency at least as much as for performance. While boosted engines swill gas at least as well as their unboosted equivalents when hustled, in typical driving they are more efficient. With EPA ratings of 16 mpg city, 23 mpg highway, the LS 460 nearly matches the Jaguar XJ AWD (16/24), but falls well short of the Audi A8 3.0T (18/28) and BMW 740Li xDrive (19/28). In the real world, the Lexus's fuel economy lags the others, including the Jaguar, to an even greater degree. In our suburban driving the LS 460's trip computer often reported averages between 15 and 16, vs. low 20s in the Jaguar. A light foot could nudge the LS's average to 18, but the XJ's to 25. On the highway the LS 460's trip computer reported averages of 24.7 and 23.3. The XJ's reported just over 30. see full Lexus LS review
