Real world mpg for 5.0 version

I'm getting about 19.5 mpg combined. Granted I only drive the car once a week. The gas mileage on this car is awesome so far, think it's better than my lower horsepower Chrysler 300S V8. I also drive mostly in ECO mode, and on the freeway.

Last weekend however, I was driving down this backroard area on the way to check out a wedding venue. The road was twisty and empty, so obviously I was driving rather spirted. Then all of a sudden, a Corvette Grand Sport (2012-2013) came right up on my a**. I pulled over, let him pass, then I flipped the drive into Sport and played cat and mouse. After keeping up with this guy for a few miles, I let off because I had to make a turn. My frigging mpg actually went up. I was driving anywhere from 35-pull me over.

Driving back, and into the city environmento, my mpg was right at 19.2, down from 19.5.

My road trip to L.A, 6 1/2 hours, gave me about 25-26. Was not using cruise control, could've been a lot better if I did.
 
Did you ever calculate the actual mileage using miles driven/gallons re-fueled?
Prior to this trip I have not, but since I was trying to take a jab at my buddy regarding mileage comparisons, I retained the gas receipts and crunched the numbers.
The on-board computer was about .5 mpg more optimistic than my handheld computer numbers.

I was happily surprised with either number. Long stretches of the trip were on divided highway. However, some was in urban congested traffic, some reaching elevations up to 8,000ft and some on remote, two lane desert roads with sparse traffic where I would set the C.C. at 100mph.

I'm sure in-town driving mpg would plummet trying to move this 4500+lb beast from traffic light to traffic light. On open highway,with the V-8 and 8 spd trans, all that mass seems to just cruise along effortlessly, which met one of my personal objectives in my decision to purchase a Genesis with the 5.0.
 
Over 20K miles, I get about 15 mpg in town, 25-26 on highway at 75-80 mph and about 20-21 mpg overall. I can't see where ECO mode makes any difference and in Sport mode the mileage drops about 10%. I can't see where premium fuel makes any difference either. It seems that throttle response is better with premium fuel. I use premium most of the time with fuel being so cheap
 
16 to 17 mixed. if your in LA traffic expect 16. 23 mpg will be the best u get if your in no traffic. I used to have a 2015 5.0......expect about 21 mpg mixed for the 3.8.

this is real world driving. not some retired owner living in Wisconsin driving.
 
17-18 mpg mostly city driving. Best on highway so far is 25-26
 
According to Car & Driver, there are 0.9 seconds between the 3.8 and the 5.0 acceleration time from 0-60 - both these are based on actual instrumented tests, not manufacturers brochure numbers:

2015 5.0 = 5.0 seconds
2015 3.8 = 5.9 seconds

http://www.caranddriver.com/hyundai/genesis

Does that make the 5.0 "sluggish" too, or is less than a second the difference between "sluggish" and "fast"?

Yes, one second to 60 is a big difference. Even so, most tests of the 5.0 showed 5 seconds or so. The 3.8 has been tested as slow as 7.2 to 60.

Clearly, if you bought the 3.8 your focus is not on performance so why the upset over the comparisons?

I'm not upset about anything, I just dislike misinformation and false statements. "Sluggish" is a false statement - under 6 seconds to 60 mph was what a 2005 Porsche Boxster would do. I haven't heard anyone call that car sluggish.

A one second difference from 0-60 makes absolutely no difference in any normal driving situation - it matters to boy racers who want to smoke people from a stoplight - it matters nowhere else. One second slower to 60 also doesn't make a car "sluggish", which is what someone posted.

If Car & Driver took two cars, instrumented them and tested the 0-60 times under comparable driving conditions, I have no reason to doubt their data. Picking the best data for the 5.0 ("most tests show") and then the worst data for the 3.8 ("has been tested as slow as") is not really a valid comparison (unless you are a politician). I provided links to both my numbers, measured by the same source under what I assume are similar test parameters.

The 5.0 is clearly faster than the 3.8 - but the 3.8 is not "sluggish", and it apparently isn't significantly slower to 60 according to the data I provided. I really don't care about the performance, the 3.8 has plenty enough for every driving situation outside of a track day - I doubt many Genesis owners track their car.

I have purchased an ODB-II data logging device, and a GPS recorder a few weeks ago, so I'll be able to perform my own 0-60 time tests. I'm happy to invite an owner of a 5.0 car to meet and run tests under the same conditions on the same track with me to get comparable data. I really don't care about the "my epeen is bigger/faster than yours" conversation, I enjoy data and facts, and I would enjoy having some actual data to end the speculation.
 
The V6 is far from sluggish unless you compare it back to back with the V8 then is does seem slow in comparison but not sluggish. It is more than adequate and actually quite powerful for a V6 in such a heavy car. The problem here is the heavy car part. Real world numbers are easy to find on youtube where we know nobody was paid off to fudge numbers. Here is a V6 one. https://www.youtube.com/watch?v=XH67lNCuRAo

It's best to just ignore jimbo's comments as he likes to antagonize V6 owners.He has deluded himself into thinking that his V8 luxo cruiser is a performance car just because it goes fast in a straight line (certainly noticeably faster than the V6 if you push it). Most reasonable people get that the V6 has plenty of power for normal driving.

Of course, folks who are truly into overall performance would have bought an actual sports sedan in the first place. The more balanced folks who bought the V8 for it's extra power (like Midnightsun) just enjoy that aspect without needing to childishly put down V6 owners every time the power topic comes up.

You are adding fuel to the fire you are trying to put out. The V8 is clearly faster than the V6, that's settled science. If it's a second or a little more or less, it's still faster. The closer the gap between the two is not going to make your car better or less "sluggish" to anyone but you. Your expense in performance analyzing tools will not make V8 drivers pine for a V6, nor V6 drivers desire a V8. These contests are never won - for every test you do someone will have one that is closer to their desires or explained by weather, driver, tires, etc. This is an old argument that tracks every car with a V6/V8 option.

I didn't watch the video yet, but wouldn't one assume that if someone is "paid off" they would be equally paid off for any vehicle tested? Or are you implying that someone from Hyundai went to Car & Driver and paid them to come up with better numbers for the 3.8L and did not to the same thing for the 5.0L - to make the V6 look faster in comparison to the V8?

The video will be of value if the person who made the video has also tested a V8 on the same road, with the same equipment, under the same circumstances. Otherwise, it's just another data point with little value.

Here's a video that shows the 5.0 (AWD) at 6.1 secs: https://www.youtube.com/watch?v=r1393bA6XaQ

Real world stop and go traffic on my way to work in ECO mode, I can get about 21mpg. This is compared to the same route in my 2015 STI where I could get about 20mpg.

This thread escalated...thought we were talking about mpg...

I want to head down to the track to give you guys numbers but the past weekends have either been too hot or raining. If you want your car to take off quick, etc., slap on some new tires, preferable summer performance only. If the weather is nice this weekend, I'll grab some numbers for you guys.

Also, that 1 second difference 0-60 does make a difference. Then again, it also depends on the driver. Too many factors, headache in the making.

Sluggish is a relative term not a false statement.

For someone who claims "I really don't care about performance" you seem to really care about performance, having bought equipment to test, etc.

Masquerading your opinion as fact ", the 3.8 has plenty enough for every driving situation outside of a track day " seems odd for someone who enjoys data and "facts".

I don't care if you are interested in performance, not interested in performance or are somewhere in between. But compared to the 5.0, the 3.8 is sluggish, just as the original poster ( who doesn't own either car and so would seem to have no ax to grind) noted.
 
Jimbo is sort of correct - when pushed hard, the 5.0 is definitely noticeably faster than the 3.8 - while the term sluggish is a poor choice by it's common definition, he can use whatever word he wants if it makes him feel better...

Just like one can say that that compared to the 3.8 AWD (or RWD), the 5.0 has less responsive, heavier handling feel... or, that compared to the 3.8 AWD, the 5.0 RWD is nowhere near as sure footed and has inferior handling/power transmission - especially on wet, icy or uneven roads. It's all relative, of course - but just sayin...

Different things are important to different people. Of course folks in Canada, like Midnightsun, get the best of both worlds with their 5.0 AWD's.
 
To be fair I just finished test driving a Lexus IS F (V8 416 HP) so yeah in relation to that car and the 5.0 the 3.8 was "sluggish".
 
I get 18 mpg plus in the city and 25 mpg or better on the highway.
 
I average 21 MPG with mine. I strickly burn Mobil Super Unleaded fuel. My drive is 50/50 city & highway. On long road trips I am pushing 24-26 MPG depending on how heavy a foot I have that day. :D

"when pushed hard, the 5.0 is definitely noticeably faster than the 3.8" This isn't "sort of" correct. It is correct and, a fact. You may think "sluggish" is a poor choice of words, and, if it makes you feel better, you can even believe it.

I suppose if you live in the "Great White North", AWD is a necessity but here, where we don't get snow or ice, AWD just adds weight and unneeded complexity, in addition to poorer gas mileage.

Oh and as far as having inferior handling/power transmission, the electronically controlled suspension is far superior to the stock suspension except on icy roads. I'm not sure where you are driving your Genesis but it is not designed as an off road vehicle so uneven roads aren't its forte. Most roads commonly driven in the US are not so "uneven" as to require AWD. But again, if it make you happy to believe it, feel free.
