Best non-hybrid MPG: Mitsubishi Mirage
Highest MPG for a new car: Mitsubishi Mirage?
Mitsubishi's 1.2L, 3-cylinder Mirage is the first new non-hybrid car that can match an old Metro's mileage. The company says 44 mpg (US) highway, 37 city. (Some drivers are already beating that in various economy driving contests.) How? An efficient engine, very light weight and aerodynamic design.

Cheapest to own? 2015 Nissan Micra Forum
2015 Nissan Micra Forum
The Micra's fuel economy isn't its most notable feature -- the $10,000 price is. That makes it one of the cheapest cars to own. And its 109hp, 1.6L engine and good power-to-weight ratio means it's fun to drive too.

I personally recommend this tool. I've owned both versions (I and II) and can't say enough good things about it. If you're serious about saving fuel, get one.

my old 1989 Honda Accord EX After claiming yesterday that I could regularly beat the EPA ratings in my old Honda Accord EX, I looked it up just to confirm.

According (pardon the pun) to, my car, a 1989 4-door, 5-speed, with a carbureted engine, is rated at 27/34 mpg (US) city/highway (8.7/6.9 L/100km, 32.4/40.8 mpg IMP).*

In summertime highway driving, I regularly got 40 mpg US (5.9 L/100km, or 48 mpg IMP).

That's beating the EPA estimate by 18%.

bathroom scale My suspicion that the official mileage figures for the Firefly are overly optimistic are gradually being confirmed.

Just got back from a weekend away, having put around 750 km on the car over a couple of days. Ideal conditions were had for a high mpg run: warm temperatures (25 C), calm winds, relaxed highway driving (95 km/h average).

The results?

front - 1998 Pontiac Firefly Welcome to the bottom of the automotive food chain!

When this car was new, it was the cheapest car for sale in the Canadian market (the U.S. had the bottom-feeding Yugo for a few years).

And my particular car is the cheapest of the cheap, with absolutely no optional equipment. No power steering. No tachometer. No rear wiper. No privacy cover under the hatchback (I made one). No remote hatch or fuel door release. There isn't even a trip odometer.

How cheap is it? It's so cheap, only the driver's door gets a switch to turn the interior light on when the door is opened. The passenger side has a hole where the switch should go, but there's just a blank in its place.

But is cheap bad? Depends what you mean by bad.

I've been interested in fuel-efficiency for some time. So this spring when it came time to replace my 16 year old Honda Accord, I decided to put my money where my interests were and try one of the Suzuki clones.

I turned to the Internet to find out if they're any good ... and didn't really find what I was looking for.

So I built a web site instead.
