You're correct. It's an obvious error on my
part since 3.2 L is less than a gallon and 100
km is 62 miles. So the answer must be greater
than 62 mpg. This error does show what might be
involved in changing the public from mpg to L/100 km rather than km/L however.
Thanks for the correction.

Stan, your math is off. 3.2L/100km is nearly
73mpg. In the late 1990s, VW had a Lupo that
did under 3L/100km (sometimes as little as 2.5L/100km) which is nearly 100mpg.

3.2 L / 100 km = 52.5 miles per gallon.
Recently, I got 51.3 miles per gallon on my hybrid gas-electric Prius over
473 miles. That's NOW. Therefore, the VW Lupo is not "much better than a
Prius" and the Lupo will not be available until next year. Also, diesel
fuel costs 10-15 percent more than regular gasoline which makes the fuel
economy of the Prius better cost-wise . And, Toyota will add a plug-in
option to the Prius next year which will increase the miles per gallon even
further.
