An auto industry falls short of green.

PORSCHE -- a company associated with environmental friendliness like Wilt Chamberlain is with prim chastity -- is going green. On the company's stand at the Los Angeles Auto Show (starting Friday) is a front-wheel-drive, zero-emission electric car. One version of the car is a series-hybrid -- the gas engine doesn't turn the wheels but, rather, charges the batteries -- and features all-wheel drive. Very cutting-edge stuff.
