For those not familiar with these funny local units, 32 miles per Imperial gallon is about 11.3km/L (8.8 L/100km); in US funny local units: 26.6 US liquid gallons/mile.

As fuel prices increase, I think hybrids will do OK in the US where diesel cars are largely off the radar screen. In Europe I think hybrids will continue to be largely ignored as Diesel appears to be a far more robust technology.

So, just by using imperial gallons, we in the USA could improve mileage figures by 20%. Couple that with a switch to celsius scale and we'll lick global warming too. :-)
