#1 of 18 Actual Fuel Economy vs Ratings by frena

Jan 22, 2009 (10:00 am)

I'm in the process of deciding on the 6 or 8 cylinder and am curious how current owners are finding the mileage on both compared to the official MPG ratings on these engines. I haven't seen many comments on this so hope to get your feedback soon.

I have a 4.6 with 1000 miles. I drive REASONABLY, and get 18-19 city, 22-23 suburban mix, 26+ freeway (loaded w/cruise 75mph). I am still running premium fuel. It has amazing performance with excellent mileage for a 2-ton, 375hp car!

Your mpg will get better. My Azera 3.8L now can go from Houston to Dallas with the 31.8 mpg figure based on the meter. Now, it could be off little but the very fact that it can is remarkable.
 
The 31.8 mpg value is measured from downtown Houston to Lewisville (Dallas surburb).
 
The "reset" button was pressed so the count was 0 mpg.
The car is set to cruise control at 65mph.
 
Average mpg is now at 23 mpg. I have remarkably short drive to/from my work place. 23 mpg figure is good based on the fact that I go through many traffic light in the commute of 4 miles.

Does anyone know how to determine whether gas with ethanol was used in the various MPG tests? Since my MPG has decreased with ethanol, seems to me this will affect all tests. Had an oil company rep. tell me they know it decreases MPG, but Congress has mandated use of ethanol to satisfy farm lobby.

I hadn't paid much attention to the MPG until now and when I checked I got 21.4 mpg.I live in Arizona and its the middle of summer so its way hot, I'm very happy with my results.I have the 6cyl Genesis with premium package and 18 in wheels,these results are in town driving (stop & go) with A.C. cranked up.I got the ride in January and only have 4600 miles on it,to say I'm happy with this car is an understatement.I bought my first new car 40 years ago for $1,995.00 and my payments were $55.00 a month, the Genesis was a bit more than that.....LOL.Like many ppl I have had a vast assortment of cars over the years,my last ride was a 2005 CTS cady,I also have owned BMW,Lincolns,and everything in between with a few sports cars and muscle cars in the mix.The Genesis I now own is one of the best cars I have had as far as price,quality,and value are concerned and 2me its a really nice looking car.I'm not sayin the car is perfect but I'm very Happy overall and am glad I got the 6cyl,don't get me wrong the V8 is sweet but having it would probably just get me overloaded with speeding tickets, and the six has plenty of power for any situation.Now I just gotta get a road trip planned and put this car on the highway and enjoy the comfort and luxury.

#6 of 18 Real World Mileage in a Small Town by sooththetruth

Apr 04, 2010 (3:38 am)

Though computer says 19.7 mpg in town, the real world measurement is 19 mpg. That is better than the sticker, but in my V6 highway mileage is 23.5 mpg at a cruise controlled 80 mph. At 75 mph\ it has only be 24.0 mpg, and I find these numbers far below the 27 mpg claimed. This is the biggest disappointment I have had with this car.
 
My previous 1998 V8 Lexus GS400 did 17.5 and 24 mpg (and highway mileage was measured at 80 mph).

With my V6 going 70 with no A/C I got an average of 28.6 on a trip from S Florida to NE US and back

#8 of 18 Break in changes in city mileage. by sooththetruth

Apr 30, 2010 (10:57 am)

My fuel mileage in town has steadily improved in the past 1500 miles. My V6 has just turned 3K miles, and around town I have improved from 19 mpg to 20. I am a bit startled by the improvement, and some of this improvement may be that I am learning to feather the accelerator a bit better as I get used to the car. Still using Regular gas. I ALWAYS run the A/C. Been too warm in GA to go without in the past month.
 
I will not have it out on the highway til this coming weekend, and I should have waited to report, but will next week, after a 600 mile round trip. I am gratified by this improvement, and am startled by how much better than the rating it is. Usually I have to baby a car to get the rated MPG, but as of now that doesn't seem necessary.
 
Of course, my measurement of every tankful is indicative of my OCD, but I'm stuck with it, and sometimes the news is good.
 
I traded in a VW Phaeton for the Hyundai. Loved the Phaeton, but hated the OHMIGOD maintenance requirements. That car, babied, did 15 mpg about town, and 20 mpg at 80 mph cruise controlled. I had guilt about driving that car, and fears of $5 a gallon gas making me miserable if I had kept it. I dare hope that my highway mileage will improve to near claims.

There was a new MPG system put in place about two years ago that makes the teting much more like real world driving. It is much easier to beat the new EPA estimates than the old (somewhat) optimistic #s.
 
For example (from fueleconomy.gov) a 2006 Avalon was originally rated at 22/31 25 overall on the new ratings system its 20/28 23 combined.
 
Your MPG seems spot on in your Genesis. My 09 with a tick over 10K is averaging around 20 in all city or gridlock highway.

Yeah, I'm replying to myself. Took a round trip ride in my V6 Genesis, 300 miles each way. Wow, there has been improvement with break in. Initial MPG was 23.5 at a cruise controlled 80 mph. That trip occurred with only 1000 miles on the odometer, and on flat land. More recent trip started with 3500 miles on odometer. On the first leg of the current trip, I averaged 26.5 mpg at 80 mph, and that is NOT the computer reading, but the calculated mpg. The computer read 27 mpg. By the way, there was an elevation increase of just over 1000 feet on the first leg. On the way home I took a different route with less highway driving, and more 2 lane roads, though a more direct route. The car did 27.5 mpg, with about 1/3 of the miles driven between 55 to 65 mph, and there were a few stops or slowdowns in some small towns. Of course there was more of a downhill benefit on the way home, though I don't dare estimate what that elevation change meant to the mpg measurement.
 
So average both ways was 27 mpg, right on the number, and that was doing 80 mph on open highways. I am starting to believe the hype about this car.
 
Since the car is actually larger than it first appears, I consider this mileage for a car this size, this powerful, rather remarkable.
