Oddly worded. It would depend entirely on how far you drove, local gas prices, traffic, etc. In city on the lowest end, constant romps, I got as low as low 8s mpg.

Yes, too many factors on that one.
If you have to fill up more than twice a week, it is time to rethink the hellcat lifestyle.....

I get 18mpg driving 'normal' on my 80 mile round trip to werk so that's painful enough with 93 topping 3,3xx+ around me. That's one reason I drive my SuperDuty more these daze, Diesel is nearly 50-cents a gallon cheaper than 93 here and it gets a tad better fuel mileage.

But as for how bad your fuel mileage can get, My mpg average showed 13 from my last drag strip trip, that was making 8, 1/8 mile passes and burnouts and sitting in the lanes.

I learned years ago from driving SC'd Mustangs that just because you have 700+ HP ya' don't have to unleash them every-time you drive it.

Or the next post you're going to be making is complaining about "Why are my tires WORN OUT after ONLY 3000 MILES???"

Hey. Just wanted to know what your monthly gas payment is. This only applies to daily aggressive drivers. Thanks!
When I lived in CA my work commute was 60 miles a day. My 2018 Hellcat would average around 15mpg. Had I used it for all my work commuting that would have been 300 miles divided by 15 which is 20. Thus the Hellcat would have used 20 gallons of gasoline per week.

Actually it would have been more since the 60 mile work commute doesn't take into account any weekend use or errands that I would have had to run.

Just did a guick look up of gas prices where I used to live. The high is over $5/gallon. (By way of comparison I just filled up my 2020 Scat Pack fuel tank with 91 ethanol free at a cost of $3.34/gallon here in Benton County AR.) Anyhow, "average" appears to be in the $4.75/gallon range. So if I was there now I would be spending (at least) $95/week or $380/month on gasoline.

As it was my 2nd car my "commuter" car was a 2018 MINI JCW and in spite of its rather high performance aspect -- its 2.0l engine put out 228hp and had the engine been scaled up to the same size as the Hellcat engine if the HP scaled linearly the engine would have put out 706hp -- under the same driving conditions the JCW managed 30mpg average.

But I still used the Hellcat around 2 times a week for work commute. It did not like to sit.

'course, work commutes vary. Some have 0 miles -- currently since I'm now retired that's my work commute miles -- some commute a hundred or more miles per day. Some drive with a light foot others with a heavy foot.

Since I bought my 2020 Scat Pack last November I've put around 3K miles on it. It averages around 15mpg -- about the same as my Hellcat. So I have bought around 200 gallons of gasoline. Prices have ranged from around $2.20/gallon to recently a "high" of $3.39/gallon with it having dropped to $3.34/gallon.

Even assuming I would have paid $3.39/gallon that's $678 for gas since since November. So roughly for the last 6 months my Scat Pack has cost me $100/month for gasoline.

However I have a 2020 M-B cargo van I use for my DD. It has just over 10K miles since August 2020. But over 4K miles was added in a week's time when I drove it to CA and back last April. That was a one time thing. So roughly it had around 6K miles on it from my just running around here. It takes the same gasoline as my Scat Pack but gets better gas mileage around 22mpg average. This works out to approx. 273 gallons of gasoline. That's $925 worth of gasoline in 10 months or $92/month for gasoline for the van.

Thus in total I'm spending around $200/month for gasoline here. Do not hot rod the van or the Scat Pack but I don't drive either like a high miler either. Just drive them "normally" for the most part. Yeah, the Scat Pack gets the whip once in a while but not that often and for just short bursts.

back when i used to go to the office i did about 2 full tanks per week and averaged 15k miles / year. so whatever gas prices are say average $3.50 for 93 probably comes out to ~$400+/month?

@ $52 a fill-up, it comes to ~$400 a month if I drive to work 3 days a week, vs the normal 0.

I drive like a dickhead and still get 15mph though because stick shift.
Wow, I must be really bad then as I'm getting 13mpg and I thought I was taking it tame. On the tanks where I've felt I've had some fun with the car I'm seeing 9 as an average. I do rarely get to see a highway though with my cruising so that may play a big factor in it. I'm also a M6 owner.

Maybe my 93 local is a bit better? My car is also not modded with any tuning, just cutouts after mid muffler. A lot of factors play into these obviously, but I can absolutely guarantee that I dog my car whenever I get in it, not 0-60 pulls every light but when theres a straight and radar is quiet, you bet I will be winding out 4th...

I use an octane booster rather often too just to keep the gas honest.

At best, on a roadtrip to WV and back I got 25mpg with the exhaust closed, and babying it to see how high I could get the number. Worst was to OC cruise week last October, I got 13mpg because me and a buddy in his car did ~120mph the whole way there at like 2am to see if we could do the trip in under and hour.

Interesting in fact. In all honesty I probably should own a Scat Pack because I drive my car like a baby 95% of the time. This was more a car that is comfortable to drive as my other cars are the ones I drive when I want to have fun as they handle much better and I'm more a twisty person than a straight line person. I just had to have the supercharger whine and the extra power for those rarer instances where I do want to ramp on the gas getting on the toll or passing an annoying driver. I actually drive with the black key most of the time for instance. Where do I turn my man card into again? 😟 No mods that I'm aware of to the performance aspect of my car other than a JLT intake which isn't adding any power. Just put it on for the sound. My highway speed limit is 75MPH and I'm at 2400ish RPM's in 6th gear and the computer is showing around 20mpg at that time. Only time I see more than that is when I'm cruising in 6th at 55mph where it bumps up to about what you are getting.

I didn't buy the car for MPG and actually bought it more to have a fairly luxury based car that is fun to drive (my other cars are loud and obnoxious). so no worries there. I really watch it just to make sure things are working as they should. I'm wondering if maybe the previous owner threw in the 3.90 rear in the car though. Thinking that because I hear a lot of people talking about almost never using 6th gear (I use it often) and my highway cruise RPM.

I use 6th constantly, and our factory gears are a 3.70. I HIGHLY doubt anyone in their right mind would spend the money to swap out gears from a 3.70 to a 3.90 but I've seen stupid shit before...

I think sealevel might play a small part, but I have all the pics of the MPG stuff to prove my side (just in case anyone reading my comments assumed in full of shit)

I cruise at 85 @ 2650rpm and set the cruise at that speed, but to get max MPG you need to have the pedal under your foot because the car will over-rev to get to the set MPH if youre coming up a hill which kills the mpg game.

Oh, I believe you as that's inline with what the car is rated for. I know quite a lot of people have thrown the 3.90 scat pack rear in our cars, especially the track guys so they aren't shifting right at the line anymore. It's actually a fairly cheap mod all things considering since the full diff can be bought for about $750 and is an easy DIY for those whom work on their cars.

Which begs an interesting question. I wonder how the 3.09 in the A8 effects these numbers. You would think it would be worse but it may get the car in more efficient gears/rpm outside of 8th gear cruising.

Bought a Scat for all the reasons above. Couldn't afford a HC anyway, but having driven every pre-2020 trim available, the 392 ended up being the "goldilocks" experience I was after. No supercharger, but no regrets, either. The power is already nuts compared to what the lady & I get in our other cars, where overtaking requires extensive planning.

Have driven from CA to MO and back again more times than I can recall. In a variety of cars. I'm sure altitude makes a difference in gas mileage -- at around 9K feet above sea level I begin to really notice the power drop off at least in my N/A cars -- but one can't get to altitude without going up hills and it is that that really impacts gas mileage.

Running along on fairly level ground at a steady speed -- using cruise control -- the instantaneous MPG reading starts to fall as soon as the car begins to climb the grade. Worse case the MPG can fall from say 22mpg to in the low teens.

There is of course a corresponding gain in MPG when going down a grade but it never makes up for what one loses going up a grade. The problem is on a number of downgrades to avoid the car exceeding the speed limit one has to use the brakes.

My experience is wind makes a big difference. The last drive to CA and back -- starting from Benton County AR, not MO -- going west I had a pretty stiff head wind that cost several MPG. From a "normal" of say 22mpg to 20mpg even a bit less. The flip side on way back from CA I had 2 days of tail wind and the van gained several MPG.

I agree to get the best MPG requires one use the pedal. I have managed to do this a few times on my long road trips.

Using the pedal to get the car moving at say 75mph -- the speed limit -- on a stretch of flat ground then coming to a grade but keeping the pedal pressure constant to not keep the speed constant can have the speed drop off considerably. I've experienced the speed dropping from 75mph to near 50mph. Any traffic -- and there is always traffic -- comes upon one -- of course I'm in the slow lane but still -- and has to then go around.

So one gets to the top of the grade the car making maybe 50mph. Here comes the downgrade. The car picks up speed and pretty quickly obtains 75mph. Then 80mph. Then faster... Now one is in the fast lane passing all the vehicles that passed by on the up grade. But one can't continue to keep the pressure on the gas pedal constant as the car's speed gets into the ticket zone. Also, often times one comes upon slower traffic and has to slow down to await a chance to past the slower traffic.

While this technique can deliver impressive gas mileage it is impractical in my experience.

buying a car that has a gas guzzler tax and to worry about MPG is laughable. Seems like a kid is trying to figure out how to somehow own one of these and make it by on whatever money they make. IDK if I am right but I'm sure I'm not far off, asking about MPG for drivers that have heavy feet to justify the car to his parents or something lol
