Hyundai Genesis Real Gas Mileage: Cons
Year	Comment
2009	While competitors have been switching to relatively small turbocharged engines, the Genesis continues to rely on larger normally aspirated ones. Even the base car's 3.8-liter V6 is nearly twice the size of the Audi's turbocharged 2.0-liter four-cylinder engine. Also, Hyundai doesn't yet offer automatic stop/start. The most significant impact: the Genesis gets much worse fuel economy. With two-wheel drive, the A6 2.0T scored 24 mpg city, 35 mpg highway in the EPA's tests, the Genesis 3.8 only 18/29. Add all-wheel drive, and the Audi's ratings fall to 22/32, the Hyundai's to 16/25, not good. Hyundai has developed a new turbocharged 3.3-liter V6 to replace the 3.8, but it isn't clear how soon this new, more efficient and more powerful engine will be available in the Genesis G80. It won't be available when the car arrives this summer, so most likely the 2018 model year. According to the trip computer, my real-world fuel economy was well above the EPA figures. Only when I drove the Genesis fairly aggressively did the trip computer average fall below 20 mpg. On my usual suburban route it averaged around 23 mpg, and on a 70-mph highway it averaged about 30 mpg. The former was still a few mpg short of the Audi, but the latter was at least as good. If the trip computer is accurate, the fuel economy of the Genesis isn't nearly as dismal as the EPA ratings indicate. see full Hyundai Genesis review

Hyundai Genesis Real Gas Mileage: Pros

2012	4dr Sedan 333-horsepower 3.8L V6 8-speed shiftable automatic RWD	This is my second Genesis. First one was a 2010 4.6L and this has the 6 cyl and it is nearly as quick but gets better fuel mileage. I get in the high 20's on the highway. Used to get 25 to 27 in the 8cyl. This 2012 has an 8 speed transmission compared to the 2010's 7 speed. see full Hyundai Genesis review
2010	4dr Sedan 375-horsepower 4.6L V8 6-speed shiftable automatic RWD	about average for a V8, nothing special see full Hyundai Genesis review

2010	4dr Sedan 375-horsepower 4.6L V8 6-speed shiftable automatic RWD	I would like the economy to be higher... 20-28 range see full Hyundai Genesis review
2009	4dr Sedan 290-horsepower 3.8L V6 6-speed shiftable automatic RWD	With all the added technology, I would have expected better mileage. I average slightly less than 20 MPH and that is the same as an older heavier STS without the latest and greatest engine management features. see full Hyundai Genesis review
2009	4dr Sedan 375-horsepower 4.6L V8 6-speed shiftable automatic RWD	Others say they are getting the 18 to 24 MPG claimed. I find that when I do 80% "suburban driving" (strip malls, lights, in/out of car, etc), I get 16 at best. When I am doing 80 on the highway w/ cruise control, I get 23-26. see full Hyundai Genesis review

Nissan Quest Real Gas Mileage: Pros
Year	Body/Powertrain	Comment
2014	4dr Minivan, ext. 260-horsepower 3.5L V6 CVT FWD	I was hoping for slightly better fuel economy, but for a 4500 lbs vehicle, I really shouldn't be complaining. In predominantly hilly suburban driving, I'm averaging a couple miles below the estimated city fuel economy number. On 100% hilly highway miles, I'm right about at or maybe 1 mpg above the estimated fuel economy. It would be nice to acheive better highway mpg, but I suppose that's the trade-off for having a torquey engine. You would think the CVT would improve things, and maybe in fact it is helping the poor fuel economy of the aging VQ engine design, but I also think the CVT transmission is a cost-cutting measure by Nissan. It would be nicer to have one of the 7 speed transmissions found in the Infiniti lineup. see full Nissan Quest review
