“Makes no sense to me”
Kind of like a Chevy Volt which adds hundreds of lbs of weight and thousands of dollars in cost, so you can go around 35 miles on electricity...or approximately the range of 1 gallon of gas.

“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.”
