The Fuel Mileage thread, what's your MPG?

Miscellaneous and Personal Stuff I Must Share
1

Pretty basic thread, what do you drive, what kind of roads, and what’s your mileage?

let’s keep this fact-based, no brand wars, no what fuel is better wars, electrics are welcome as well, if it has tires and drives on a road, it qualifies, cars/trucks/SUV/motorcycles/scooters, heck, even powered skateboards and segways…

I’ll promise to keep my Prius-bashing in check, (I admit i’m not a fan, not in the target market), as long as you keep your diesel-bashing under wraps as well, m’kay? :wink:

Here goes;

Daily driver; '12 VW Golf TDI, 2.0L 4 cylinder turbodiesel, 140 HP/236 TQ, DSG,

Roads; mostly secondary streets and small towns, speeds from 25-55 MPH, occasional highway trips of 65-70 (Maine turnpike is 70 MPH)

City/small town; 30-32 MPG
Secondary streets/backroads; 36-44 MPG (depends on hills ……and how much fun i’m having :wink: )
Highway; 38-45 (short highway trips, I haven’t yet done a long run, so the jury is still out on long highway drives, but easily 40-42+ if not higher)

Backup/Fun/Secondary car; '07 VW Rabbit 2 door 5 speed manual, 2.5L Five cylinder**, 150 HP, 172 TQ

City/Town; 18-22 MPG
Secondary/backroads; 23-27 MPG
Highway; 28-31 MPG

**The 5 cyl. the power of a slightly bigger 4 cylinder, the thirst of a slightly smaller 6 cylinder, but oh-so-fun to drive, and a lovely “trumpety” exhaust growl

I have a Subaru Outback with a 2.0 litre Diesel engine. My driving is about a half / half mix of freeway and urban roads and I average 35 mpg. I actually get my best MPG when city driving. I think it is because the lower speeds are more efficient and the city I drive in, at the times I drive, doesn’t have a lot of stop / start.

2019 Mazda MX-5 Miata. My driving is mostly commuting on arterial city streets with lots of stop lights, and the occasional fun weekend drive on rural back roads. I’m getting 28-31 MPG, which is surprisingly good for a sports car although perhaps not so unexpected given how small and light it is. That’s actually slightly better than what my old 2009 Corolla got on the same commute. I do like to Zoom-Zoom as well, I bet if I drove it more gently it would be even better. The downside is that Mazda recommends premium gas.

My daily driver is a 2016 Ford Escape, with the 2.5L 4 cylinder. I get around 23-26 in town, and 28-32 on long highway trips.
Compared to my 2002 Hyundai Santa Fe, it’s a gas sipper - that thing got execrable gas mileage - around 17 in town.

I also have a 2000 F-150 4.2l V6. It gets a surprising 17-18 in town and better than 19 on the highway. But, I’m still on the same tank of gas from November, so that shows how much I drive it.

If it is possible to lose a thread I think I probably will in this one. '06 Mustang GT convertible (less aerodynamic) with modifications and a performance tune. It has a readout that shows average MPG and I try hard to skip past it as quickly as possible. Occasionally on a pure highway trip I’ve crept into the very low 20’s but normally it is around 12 or so. And to add insult to injury it requires premium gas.

I wouldn’t trade it for the world.

2018 Chevrolet Camaro SS.

Back and forth to work, 27 mile round trip. 32 of the 52 interstate. Average MPG consistently in the high 25s.

Weekends, shorter trips in suburbia. Rarely exceed 50 mph. My during the weekend MPG 19-20.

Obviously if I do a lot of “getting on it” or canyon-carving and such, it would be in the low/mid teens.

7

Just bought the wimpiest car I will ever own. A 2001 Honda Insight…
42-48 Average (get 50-60 on road trips).

It’s cute (check out the Retro-Futuristic butt end, with skirts over the rear wheels), but when they made the first hybrid, it had only one trick: gas mileage.

Comfort? You’re feeling every crack in the asphalt. Road noise? What? Sorry, did you say Toad Poise? Yeah, that’s an issue. Room? Seats two (and Muggsy Bogues is the only basketball player who’d fit), with minimal storage. Speed? Pfft. Acceleration? It does 0-60 by Tuesday.

Maybe I’m still a little heady and smitten with diesel love, but I think a small diesel motor in a Miata sized platform would be amazing!

Diesels build their power at low RPM, and are extremely torque heavy, which makes them very drivable at low to medium speeds, they do tend to get out of breath on highways, but twisty backroads would be ideal, having all that usable torque available would assist the Miata’s already amazing handling

A rear wheel drive small diesel with manual transmission? Yes please!

For those who have never experienced a small diesel passenger car, The driving dynamics are quite different than a gasoline car, diesels shove you back in your seat from a stop, and under power, they pull like a freight train, there’s always torque when you need it

Diesel Miata, please! :slight_smile:

Let’s see… 7000 miles, divided by 0 gallons. Hmm, I think I broke my calculator.

2018 Tesla Model 3, rear-wheel-drive, long range. Efficiency is rated in watt-hours/mile (the lower the better). My lifetime average is 252 W-h/mi. About half the miles are my daily commute at ~50 mph, but with lots of stop lights; the other half are highway miles at 70 mph.

Under the right conditions, I can get under 200 W-h/mi. That’s highway miles at ~60 mph. I don’t like going that slowly, but sometimes that’s just how traffic goes. I actually don’t mind traffic as much these days since it comes with a nice efficiency boost :).

I pay about 11¢ per kW-h. That’s means I’m only paying 2.8¢/mi on average, and 2.1¢/mi under good conditions. A comparable gas car would be about 10¢/mi around here.

10

2018 Prius. Overall 53.7 mpg since I bought it. Generally it gets a little better mileage in city driving and a little worse on the highway.

11

As an aside, the unit watt-hours/mile is a unit of force. That means it has a direct conversion to pounds. And as it turns out, the conversion factor is almost exactly 1/2. So, the 252 W-h/mi I get in the Model 3 converts to 126 pounds. That means that the average resistance to my car’s motion is about the weight of a small person (almost exactly my own weight, in fact). It’s fairly remarkable that that’s enough average force to move a car weighing nearly two tons (and that includes all factors: air resistance, rolling resistance, drivetrain inefficiency, etc.).

12

Very cool little car, Hondas have a very well deserved reputation for being bulletproof, and the fact that it was available with a proper, real manual transmission is even better, enjoy that little gem!

any plan on improving it’s performance, perhaps a bigger/more powerful electric assist motor? dropping a Tesla motor in it and going all electric? an Insight would make a great sleeper chassis, go full electric set up for performance, but keep the chassis looking stock…

2016 Nissan Rogue

I regularly get 25-30 mpg in town. Out on the freeways that jumps to 35 mpg or so. The best recorded gas mileage I’ve gotten is 51 mpg on the way to work one morning. 5 miles, and I hit all the lights and it’s all downhill. :smiley:

14

2013 Honda Odyssey EX-L. Overall average:24mpg, if all highway can hit over 30 mpg.

It fits my wide load, and if I got in something smaller/lower, I wouldn’t be getting out without a James Bond ejector seat.

15

My vehicle has tires and drives on roads, but I’m not sure how to calculate its miles per gallon. I guess I get about 10 km per 3000 Calories, on average?

16

Since 3/31/2018, until 6/3/2019 my MPG has been 20.497. That is about 20% outside the city, 80% intown.

17

BPM? (Burgers Per Mile? :wink: )

18

My spreadsheet is on my office computer, but I think I’m averaging about 44.6 mpg in a 2005 Prius. Mostly freeway, and I tend to drive fast.

19

There are cranksets/bike computer combos that measure power via crank torque and rotation rate. The rest of the drivetrain on a bike is extremely efficient, so this is a pretty good proxy for overall power. Divide by speed and you get W-h/mi, the same as an EV. For instance, you might average 100 W at 15 mph. That’s 6.7 W-h/mi (in contrast to the 200-400 that an EV gets).

I certainly hope you do better than that…
An hour of running on the treadmill is around 400 kCal, and that’s around 10km for me.
