Detroit CEOs take road less traveled to Washington

After their CEOs first appearances before Congress, GM and Ford said they would sell some, but not all, of their corporate jets.

To showcase its "green" vehicles, GM will drive several other fuel-efficient cars to DC. The entourage is expected to include a Buick Lucerne that can run on 85-percent ethanol and a Chevrolet Cobalt hybrid.

Ford also has more than one car driving to Washington. A spokesman declined to say exactly how many were going to the Capitol, but noted they were all hybrid vehicles.

"Part of this is being done to showcase fuel-efficient and environment-friendly vehicles," GM spokesman Tom Wilkinson said. "We have been running into a bit of a perception gap in Washington DC...and this is to close that perception gap."

Of course, it would have been more environmentally friendly to carpool.
