TrueDelta Reviews the Real Gas Mileage of the Lexus IS

Lexus IS Real Gas Mileage: Cons
YearComment
The 2014 IS 350 manages 19 mpg in the EPA city test, and 28 in the highway test. While these figures tie those for the Cadillac ATS 3.6, they're short of the 23/33 achieved by the BMW 335i. Also, with both the BMW and the Cadillac you can step down to more efficient turbocharged four-cylinder engines. With the new IS, your only other engine option is a small V6, and its fuel economy is only a couple mpg better than that of the big V6 (21/30). The BMW has a further advantage: you can set the steering and suspension to "Sport" without forcing the transmission to hold a lower gear. In the 2014 IS 350 F Sport, the sport modes are "all or nothing." Select one to firm up the steering and suspension, and the transmission won't shift beyond sixth gear, reducing fuel economy. Lexus should follow Audi's lead and offer an "Individual" mode, where each system (powertrain, steering, suspension, etc.) can be set separately. see full Lexus IS review

2006 4dr Sedan 204-horsepower 2.5L V6
6-speed shiftable automatic RWD		 At around 200hp, it isnt the fastest luxury sedan. However, on my roadtrip across the eastern / mid eastern USA I was able to get ~33 ish mpg (computer reported) on flat terrain and premium fuel. City mpg is what I expect,22-25ish. But I think it is great as a long distance comfortable vehicle. see full Lexus IS review

2009 4dr Sedan 204-horsepower 2.5L V6
6-speed shiftable automatic RWD		 Wish it got better fuel economy for such a small car and engine... Sticker is 21/29, I'm averaging 27MPG (computer read); avg on hwy is about 33-34 mpg while city is about 19-23mpg. Engine variety would help, a 4 cyl + turbo or something, but toyota/lexus isn't exactly known for that. see full Lexus IS review
2002 4dr Wagon 215-horsepower 3.0L I6
5-speed shiftable automatic RWD		 For a small, relatively modestly powered car, it gets poor economy. Corvettes and most Porsches get better economy. see full Lexus IS review
 

TrueDelta Reviews the Real Gas Mileage of the Volkswagen Passat

Volkswagen Passat Real Gas Mileage: Pros
YearComment
2015 Though as powerful as the 170-horse 2.5-liter five-cylinder engine it replaced, and stronger through the midrange, the Passat's new 1.8-liter turbocharged four-cylinder engine earns significantly better EPA fuel economy ratings: 24 mpg city and 35 mpg highway vs. 22 and 32, respectively. Fitted with the six-speed automatic transmission, the difference widens: 24/36 vs. 22/31. Alas, the Mazda6 scores a bit higher: 25/37 with a six-speed manual and 26/38 with a six-speed automatic. In my real-world driving, I observed similar numbers in both cars, and the Passat managed the highest observed one-time average on my standard route to my son's school: 39.9 mpg. The Mazda's best on this route was 38. More typically I observed averages in the low 30s when driving both cars casually in the suburbs. Push them, and averages can fall into the mid-20s, even the low-20s. On the highway, the Passat's trip computer reported an average of 35, the Mazda6's an average of 36. Too close to call. What is clear is that both sedans deliver much better fuel economy than could be expected when the current Passat was introduced three years ago. This said, those seeking to maximize fuel economy, and who drive enough miles to offset a higher initial cost, have an even better option in the Passat's available diesel engine. The TDI engine has been further improved for 2015. It now peaks at 150 horsepower rather than 140. And it now rates 30/44 mpg with a six-speed manual transmission and 30/42 with a six-speed dual-clutch automated manual transmission; plus owners often beat the EPA ratings. see full Volkswagen Passat review

2019 0 As mentioned previously, the Passant starts in second gear unless you push down hard on the accelertor. Since most of the time I did not do that, I got outsanding gas mileage with my just over 500 miles of driving this past week. I averaged 28 mpg. This includes 30 mpg on the highway, and 25 mpg in modest city driving. Overall quite good gas mileage in the warm Florida weather. The EPA estimate for this car is much higher 25 city, 36 highway. To be honest, I never came close to averaging 36 on the highway but then again, I had to run the AC heavily in the Florida heat and the speed limit is 70 mph (I averaged 74 mph). Perhaps the EPA testing was done in Washington DC where they don't need to run the AC as much as I had to and the EPA tests are done at 55 mph? In any case, this gas mileage is quite good for a car this size and I had no issues with it. This is better than most cars I have driven under similar circumstances in the Florida heat. see full Volkswagen Passat review

2013 4dr Sedan turbocharged 140hp 2.0L I4 Diesel
6-speed manual FWD		 really exceedes my expectations. based on what i read and the fact that i do 95% hwy driving i expected to exceed the epa estimate of 43 mpg. in reality i can obtain upwards of 54mpg (computer) or ~51 mpg (corrected) on rural highways (62mph) and 47mpg on interstates (75mph) without a problem. that is in the neighborhood of a 10-20% improvement ABOVE epa estimates. simply amazing. see full Volkswagen Passat review
