Good news to those that can afford it. Porsche promises the Panemare to be offered in a hybrid flavor when it finally bows in 2009, with a 30-percent boost in fuel economy.

At the Los Angeles Auto Show, Porsche AG presents a milestone in automobile development to the public -- the electric-drive Lohner-Porsche from the year 1900, one of the world's first zero emission vehicles and, accordingly, a forerunner for hybrid drive.

Citing rising environmental concerns among car buyers, German luxury sports car-maker Porsche said Monday it's developing a hybrid drivetrain for its Cayenne SUV to drastically cut fuel consumption.
