who has the highest mpg dd?

Anyone above 40, even 50 mpg in their daily driver? Seems with all the ingenuity here, there is a likely chance for some real fuel sippers. Should be based on at least a 3 tank average. Anything besides VW diesels?

I used to see more than 40mpg in an '85 CRX DX that I daily drove in the early 90s. Now I only get 34-36mpg in my '07 Fit Sport.

Is it Vigo whom has the first gen Insight? I'd pick that one. Or the guy with the Volt, if you want to roll like that.

Not me, I'm usually around 18-20mpg.

It certainly isn't me. I have an old full size van and an rx8. Do I win worst mileage DD?

I'm getting an average of 43.5 in my B3 powered Miata. I hope to get the average up to 50 ish this year.

Definitely isn't me, 21mpg Dakota, 18mpg diesel F250, and a 15 or 17mpg Avalanche.....

Roughly 31mpg in the 92 Nissan Sentra.

Elantra returns 40 mpg routinely, 43 at 70+ mph en route to Daytona 24.

F700 currently in the low single digits though

My 2005 SV650 gets around 45mpg. Today was my 18th consecutive day on it, which is every day I have had it.

52 in the prius. 41 with the civic.

My TDI Cup used to get an average right around 40( mostly city and not driving conservatively) with a high of 53mpg on a 14 hour interstate trip. Damn I should of kept that car

65-75 mpg.

1977 XL125 with a 200cc Lifan motor.... does daily "rider" count?

(yes, I do ride it year round, every month of the year, not much rain out here in LA LA land)

Equal times in traffic jam and highway, the Yugo got around 40mpg.

My DD Prizm gets ~35, never tried hypermiling it, worst tank ever was 30.5.

I got 41mpg on the highway going to and from the $2012 Challenge in my MX6 GT. Average taken over about 1700 miles.

I typically see about 34-35mpg combined with it. I'm looking to hit 45mpg or more this $2013 Challenge trip with some minor modification. I'm fairly certain i could hit 50mpg with some lean-burn Megasquirt trickery.

I'm banking on hitting 45mpg just by swapping in a numerically lower final drive, which should keep it out of open loop on the highway at 80mph.

My Volt gets infinite "gas" mileage on the commute. I use 1.3 kWh to get to work, and another 1.3 to get home, so 2.6 * 9 cents per kWh gives me 23.4c per day, or 1 /15th of a gallon cost equivalency (based on $3.50/gallon gasoline). With a 12 mile round trip commute, that equals a cost equivalency of 180 mpg. As gasoline goes back up for the summer, that mpg equivalency will only go up.

18 on a 4 cyl.

I'm retired, so no commute. I can get the MINI up to 37-38 mpg on the highway, more during rush hour with the draft.

Release the handbrake!

My regular DD is the C30, I usually only get 25-26 in mixed driving, but to be honest the best I’ve ever seen is 27.5mph. Not great but it is an old tech 5 cyl turbo with torque to make the average V8 blush.

I’m much more impressed with our 2013 Mustang. It’s the hairdresser edition a V6 auto convertible. My wife DD’s it on all city streets and gets around 21-22. This weekend we drove across the state and got almost 30mpg for an average of close to 80mph (actualy77.43mph and 29.9mpg) To average that speed including city streets at each end there were obviously extended periods above that speed. I was massively impressed with that mileage. The return trip wasn’t as good but it was getting late so we weren’t as conservative on our speed.

Disclaimer, this is a made up post and this was really recorded on a closed course not the highway.

Anyone ever do any aero mods to help mpg? I have read about some success with home made boattails and under belly mods.

I sold my rabbit pickup, but averaged 53mpg wih it over the 14k I put on it. My 2012 Mazda5 has averaged 29.2 over its 50k miles.

My '93 Toyolla wagon gets 36 mpg on the highway.

On a slightly-related note, how does my daily beater have as many "up votes" as my Mustang?!

Haha. Awaiting engine swap.

24-27* mpg in the 5.4L swapped Crown Vic!!!

*When I don't hoon the hell out of it, which was this one tank of gas I tried to see how well I could actually do... Mostly though, it's around 14-17 because throttle steer.
