I thought I'd share this. Usually we talk about miles per gallon or litres per 100km, but one strategy I've found useful for helping to plan my driving more effectively is to think in terms of dollars per hour of driving.
Thinking this way requires some assumptions, but the specific numbers don't matter too much. Here I'll assume city driving, averaging 50 km/h, with gas at $1.10/litre. The mileage numbers I'm using come from Canada's Energuide. I'm ignoring all other costs (insurance, maintenance, etc.) which would push the dollars per hour costs higher.
For example, a Ford Explorer costs $11.44 per hour to drive in the city. Putting this in context, if you zip out to Tim's for a $1.20 medium coffee, and the drive there and back only takes 20 minutes total, your coffee ends up costing $5.01! A 30 minute total zip out to the movie rental store to rent a DVD for $3.99 ends up costing a total of $9.71!
Kind of puts things in perspective? It definitely pays to plan to combine multiple trips whenever you go anywhere.
Other examples:
- a manual transmission, base Ford F150 costs $8.75 / hour
- a manual transmission, base Honda Accord costs $4.95 / hour
- a manual transmission Toyota Echo costs $3.69 / hour
