Oh, I see. You're one of those "trendy" folks that needs a new car every decade or hundred kilomiles. I still love my trusty 1976 280Z with 170K miles (I bike most places, which is why it isn't more miles).

Looking at gallons per 1,000 miles makes the comparison easy. The Escalade's fuel usage went from 66.6 to 60.6 gallons per kilomile, while the Prius' consumption fell from 20 to 16.6 gallons per kilomile. Saving 6 gallons beats saving 3.3.

The route, a close collaboration between myself and the AA route planner, totals 160 miles. To put that into context, if you were to refer to a thousand miles as a 'kilomile' then the trek I am about to attempt is almost one fifth of a kilomile.
