Is it possible? Can I beat the Toyota Prius with a Corolla?

July 28, 2007

Working at a company that offers one of the most energy efficient servers available today, I have one more reason to save energy (the other reasons are well-known).

The question was: Is it possible to drive a standard Toyota Corolla Combi (Station Wagon) 1.6 l, 81 kW (110 hp) (Engine 3ZZ-FE) more fuel effectively than a Toyota Prius?

Well, it depends. Depends on what and how you compare, of course. Let’s see: If you look at the average fuel consumption of the Prius as documented here, you can see that the average fuel consumption of the Prius (models I and II) as entered by about 270 users is about 5.2 l/100 km which equals to 45 mpg.

I was pretty sure that I could never drive more fuel effectively than the best Prius driver (once I hit the break, I lose). But I wanted to know how much fuel I could save by driving as good as possible, which is:

  1. use your bike for short distances
  2. don’t drive fast (at most 100 km/h = 62 mph)
  3. avoid using the breaks: When you have to slow down, declutch or lift the gas pedal (if traffic allows)
  4. switch off the engine when stopping for more than 20 seconds

The result was pretty amazing: 5.26 l/100 km = 44.7 mpg. By the way – the average fuel consumption of similar Toyota Corollas as entered by about 40 other drivers is about 7.7 l/100 km = 30.5 mpg.

If only my Corolla had a gearbox which would allow me to drive 100 km/h at just 1800 rpm instead of 3000 rpm as of today, I am sure I could bring it down to 4.5 l/100 km (52.3 mpg).


If you like vi or Vim, you’ll also like Vimperator!

Imagine you could have a browser with a command line which has nearly all important vi commands! Imagine you could scroll a page down using f, search using “/”, or navigate to another tab using “b” and the number of the tab!
How? Just go to the Vimperator site, download the latest xpi file and drag it into your Firefox window to install it.
Be aware that it’s still beta – currently open bugs are here. But it works reasonably well already.
