Why would Tata motors risk its reputation by fudging specs on the air car? 4000 lbs of air pressure (volume unknown) powering a lightweight tubular aluminum lattice supporting an aerodynamic fiberglass shell under optimum conditions is gonna go a helluva long way. 100 miles sounds optimistic to me. I'd still buy it if it only went 30. My solar panels give me free electricity. I'd love to have a compressed-air car I can plug in when home and use around town.

I won't be buying a Chevy Volt because I don't want to be constantly buying batteries. My present car only has one battery and it seems to be the single most needing to be replaced item on the car. I don't want a car full of them!
