Fuel economy, ugh. It’s the most unsexy of all the car-number-things to care about, but since miles per gallon is really dollars per mile, we generally care a lot – especially when it comes to a daily driver. Thankfully, the government is pretty good about enforcing legislation that ensures manufacturers don’t give us numbers that are overly optimistic, and with a couple of miles wiggle-room per gallon depending on your lead or helium foot, most cars tend to deliver the efficiency claimed on the window sticker.
However, some cars may deliver significantly different results than the expected mpg numbers, if only based on the sample-of-one survey data generated by you or I and our individual test examples. Hopefully any discrepancies you’ve experienced were on the greater efficiency side of the fuel gauge, but these things can very much go either way.

As for me, the car that surprised me the most, and pleasantly, was my Mustang GT. It’s the one genuinely high-performance car I’ve owned, which I purchased new in 2012 when the lure of the then-new Coyote V8 and its 412 horsepower (not to mention X-Plan pricing via my employer at the time) proved too much to resist. The official EPA fuel economy numbers were 17 city, 26 highway, and 20 mpg combined, but I was surprised to discover the GT could manage darn near 30mpg when my travels called for a long stretch of flat and straight driving across Texas, perhaps with a tailwind. As for my daily commute, well, I wasn’t exactly easy on the gas and so the Mustang wasn’t either, and I was happy if I got 15 miles out of a gallon. But hey, that was on me.
When it comes to gas guzzlers, I’d have to say the Jeep J10 Thriftside I drove in high school was probably the most surprisingly thirsty. Not that I (or my Dad, to whom it belonged) expected it to be some kind of economy machine, but the mere nine or ten miles its AMC 258ci inline-six managed to eke out of a gallon of gas seemed super low. I’m sure the truck’s short gearing (it sure felt short, anyway) and the extra rotating mass of the 4X4 system adding to the oomph required for each acceleration took a toll, and let’s not get started on aerodynamics, but man, that truck liked to drink.
Now it’s your turn: what car or truck have you owned that got way better (or worse) fuel economy than it should have?
