Mpg

[limey43]

I'm new to this forum and new to Hyundai. I have a 2012 V6 with premium and tech. I am wondering what MPG people get, I'm only getting about 26.5mpg and expected better. I only use the car for highway use and the passat I traded with the same (29) highway rating used to give me 33-34mpg. I only have 990 miles on the car so I hope it improves.

Depends-

Speed, terrain, temperature, etc. I get 27-32 highway generally- 18-20 around town.

Wow. That is really good mileage from a Passat. You don't say if it was a 1.8T, 2.0T or V6, or TDI. It is unlikely your Genesis will return that kind of mileage. Also, keep in mind that your Genesis has about 100 hp or more (assuming you have a 4 cyl Turbo), and power takes fuel and air. Almost 27 is pretty damn good for a car the size of the Genesis and no where near broken in. If highway mileage in a larger vehicle is what you are after, have a look at the E350 Bluetec from Mercedes. I regularly go over 40 mpg on the highway with mine.

I have had two Genesis, a 2009 and a 2011, both V8s. My observation is that these motors gradually break in and do not reach their full stride until about 10K miles.
If you are serious about checking your mileage, I think the best way is to have a stretch of freeway at least 25 miles long that you can drive at a constant speed. A basic commute sometimes works for comparison. I drive between Salem, OR and Portland, OR several times a month at a fixed 70 mph. I begin measuring mileage after about ten miles, when the oil is fully warmed. When I began doing this my mileage was about 26 mpg. Now I am up to 29.5+ mpg.

I traded in my 09 VW Jetta Sportwagen tdi in on my '12 w/premium Genesis. I loved the car but VW clearly has an expensive headache with the high pressure fuel pumps on their new diesels- up around $8K to fix.
My Sportwagen got me 42mpg hwy and low to mid 30's city. But after spending 10 days at Tulsa VW broken down with the hpfp issue-my wife refused to ever go out of town in the Sportwagen again.
That being said- she drives a 05 Passat tdi that gets about 33-35 hwy so I'm pretty happy with 25-26 city. I got 31-32 @70mph on my trip to Orlando a few weeks back. That's darn respectable mileage for a 300+ hp luxury car! Still love my 98 Beetle tdi- low 40's city and as much as 52 hwy !

just over 1500 miles on my V6. I detailed my MPG experiences so far in another thread ( http://genesisowners.com/hyundai-genesis-forum/showthread.php?t=8039 ), but I'll sum it up:

We live in Sierra Vista, AZ (southeast AZ). Elevation here is 4600-5000'. We regularly drive to various destinations in Tucson AZ, (average distance is about 85 miles). Elevation of Tucson is 2300' at airport. Anyways, you can see that our average trip there takes us 'down(hill)' in elevation, and the trip back is essentially uphill. We have to drive N from our home about 32 miles or so on a divided 4 lane rural highway to I-10. Speed limit is 65 mph but I (adaptive) cruise control it to 67 mph. We hit I-10 W for the remainder of the trip, speed limit 75 mph but I cruise it to 78-79. GOING TO Tucson, we get 37 mpg (I reset the CPU mileage calculator), and I discount the drive around town as we FILL up for return trip. On the way back, we average 27 mpg. Average for trip both ways is then 32 mpg. I verify this by my "fill and record and calculate" method as well, and the results are similar. Highway speeds we average 32 or just under 32 but I am not finished breaking in the car.

As was said, MANY factors affect mpg:

1) Your driving style (leadfoot? how fast do you accelerate)
2) type of driving (highway/freeway, city, or combination) Also includes your "luck" with traffic signals, and believe it or not, the number of LEFT turns you make (or wait for).
3) Tire inflation pressures
4) Type of tires (low rolling resistance, etc)
5) The road surface itself
6) Terrain (elevation/altitude) as well as curves, turns, etc
7) Weather (humidity, temperature, etc) to include wind (any headwind or crosswind with a headwind component will affect your mpg)

Most of your fuel consumption will be from accelerating the 3200+ lb vehicle from a stop to your intended speed. So the best thing is to keep the vehicle moving....

My R Spec is getting 28.1 on the highway. No joke. I took it out to eastern Washington state last weekend and was amazed at the mpg's. I'm very happy with that and more.

 

[limey43]

Thanks for all the feedback and information. We'll be off to Canada soon so that will be a better gauge of the MPG. I generally cruise at 73 as the expressways here in MI are all 70.

I'm an old fart and one thing that has been consistent over my 60 odd years of driving is the tendency of people using MPG is a pawn in the bragging war over how many miles per gallon they get on THEIR car. The one-upmanship is always there with some people and on a forum like this, you never know whether that is a factor or not.

I learned long ago the calculate mine and keep up with it, but since I am aware of the bragging rights, I really don't pay attention to the MPG claims on the high end.

 

[Seattle Genesis]

Lol. I'm not bragging. I'm stating a fact.

I would never single out anyone, I'm just stating my experience. Your statement is not on the high end anyway.

I'm seeing very similar numbers to yours. I've had my Genny over a month but work keeps sending me away from home so I've only got about 1500 miles on her. The one week I did commute to the office (43 miles each way, mostly highway) I got about 27 on the display (26 calculated) driving about 75-80 miles an hour.

My father used to tell the story of a friend who bought a new car (this was in the '40s) and bragged endlessly about the mileage he was getting. It got better all the time. What he didn't know was that some of his friends were sneaking up in the night and adding gas to his tank.

My 2012 V8 (70-30% Highway) displays 25-26 MPG and the calculated is consistent 23-24mpg. Very happy with the MPG from my 4.6

Ditto. I watch the average mpg on the readout, but I also, (since I learned to drive in 1973) keep meticulous and accurate records of my fuel consumption. "My daddy taught me that". I generally never fuel my vehicle unless it's a FULL fillup. I record miles driven (with the help of a trip meter), the odometer reading, the date/time, price per gallon and total amount. Any other remarks I also include, like location, octane rating, etc.

I've found that while the onboard cpu meter is good, nothing really substitutes for the tried and true method of dividing the number of miles driven by the total amount of fuel. Now you can say, well, you can't be sure you fill it to the same level each time, etc etc etc. And that may be true to some extent. From one fill up to the next, you might have a discrepancy as to the 'level' of fill, but in the long run, everything averages out. (such as weather related factors) And that allows you to look for trends. If I know my fuel economy has stated to decline over the past few tanks, even just a small bit, I might want to take action. Or it might just be getting into winter, and the engine's cpu will inject more fuel to compensate for the colder, denser air.

You can average a month's or year's worth of individual averages and you will have a very VERY good picture of how your engine is doing. So when, in only a month's time, I've come to the conclusion that my vehicle gives me 32 mpg (the 3.8L V6) on highway, you can rest assured I am not 'stretching' or 'fabricating' mpg values. I have noticed that the cpu calculations are more and more accurate with the averages I calculate. Not exact yet but close enough for a solid comparison and report. I suppose you could take a sample of Genesis owners who report their MPGs here, throw out the very high and very low, and then average the rest and you'll have a pretty good real-world view of it's mpg capabilities.

I too am an "old fart"...maybe not as old as you but mid-50's.

I've heard that several times from several sources over the years and don't know anyone who actually did it. It probably has happened several times and it really would screw with someone's head . In the 40's and 50's gas was around 20 cents a gallon and sometime lower during gas wars. You could afford a trick like that a little easier then. I remember a gas war in about 1954in Fort Worth Texas where they were selling the gas for the tax only, about 11 cents. Didn't last long.

That is great. I also keep date, fuel input, miles driven, cost, & percentage Hwy to City data in Fueleconomy.org. The Genesis 4.6 only has 9 fill-ups, with 90% city averaging only 20 mpg. Hopefully that would improve later as the engine fully broken in. My other vehicle is a 06 Mazda 3 manual with 2.3l does 30 mpg at 80% city; I kept that data since 2005 - my wife thinks I'm anal retentive but it is kinda cool to see the fuel usage plot and trend.

That is so good for a new V8! At 90% Hwy, I could only get a bit over 26 mpg and 90% City is 20 mpg. Mine is a V8 2011 and it is no where close to your 2012's mpg; the extra 2 gears must have improved mileage big time. I'm curious to see long term fuel usage data from our members.

 

[Seattle Genesis]

There's an App for that. Lol. Check out iTunes and search for gas manager.

Gawd. We actually did that to a neighbor of ours when I was in high school (early 70's)..he had a Beetle and was bragging about it's fuel economy. Me and my buddies told him that if he wanted better fuel economy he should keep it absolutely and spotlessly cleaned and waxed. Well, he started with the washing and waxing. So we would add a bit of gas each night or every other night...he kept telling us how much better and better his mpgs were....so we just kept doing it for a while. He would be out there virtually every weekend doing his Bug, wash, wax, etc. Well after a few weeks of that, we started removing a bit of fuel. Now that is where it gets funny. His mpgs peaked, then stayed steady, but then started to drop off. We told him that he wasn't keeping his car slippery enough, so he started to superwax it, like on Sat and Sundays...well his mpgs kept going down so he literally was out there in his driveway after work each night (often after dark and in cold weahter) washing and waxing that damned Beetle......we finally decided to take him back the other way, and started drawing off less and less gas until his mpgs were right back at here he started several weeks (months?) before. It was a hoot. He never did figure it out, and I hope he does NOT have a Genesis now....
