my car karma, shot

We looked a bit bemused when the Hertz guy gave us a free upgrade last week to a Ford Escape XLT SUV. It’s almost exactly not the car you’d want for long freeway driving.

I just did the fuel economy for our trip. It’s not pretty. For the whole trip, we averaged 11.7 l/100km, or 20 mpg (US — that’s 24.1 mpg for UK readers). That means we used over half a cubic metre of petrol. Eek! We’re all gonna die and it’s my fault!

Litres / 100 km is a strange unit. If you do a dimensional analysis (L3/L), it ends up being a unit of area. So I’d be quite correct — if a little weird — to say I got a fuel consumption of 1.17×10-7 m2.
