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.

The EPA vs the EX (and the V8): beating the ratings

Posted Tuesday, September 13/05 in Driving efficiently

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 fueleconomy.gov, 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%.

(* Note that I use the 1988 Accord figures from fueleconomy.gov. When you look up the 1989 model, the site mistakenly shows a photo and stats for the 1990 Accord, which was a complete redesign of the 1989 model. The '88/'89 models were essentially the same.)

1992 Cadillac Seville

I could beat the ratings with my grandfather's 1993 Cadillac Seville too. The 4.6L V8 was rated at 17/26 US mpg city/highway (13.8/9.0 L/100km, 20.4/31.2 mpg IMP).

I borrowed it once to specifically put some fuel-efficient driving techniques to the test. In city driving, I got 11.4 L/100km (24.8 mpg IMP / 20.7 mpg US). On the highway, I got 7.6 L/100km (37.2 mpg IMP / 31 mpg US). That's 23.5% and 19% better than the EPA ratings, respectively.

So it can be done.

Just not with a '98 Firefly, apparently.
