“Fuel economy obsessives will find lots to like about this car. On a full tank, the Highlander has a range of 300 or 400 miles, according to Chris Santucci, the Toyota engineer sitting in the passenger seat beside me. Filling up takes about five minutes — not much longer than your typical vehicle — but you can go much farther than even today’s best hybrids. The Toyota Prius gets about 50 miles to the gallon; the Highlander gas-electric hybrid gets about 27 under optimal conditions. The hydrogen-based Highlander? Sixty miles per gallon.”
