Amongst the numerous one-off concept cars and rare historic vehicles set to be auctioned off at the forthcoming RM Auctions sale in Monterey, California, Ford has contributed two of its own unique concept cars to be sold. All proceeds of the sale will go to the Juvenile Diabetes Research Foundation (JDRF) charity. The race-inspired 2005 Ford Shelby GR-1 concept and the 2001 Thunderbird Sports Roadster concept will be presented by the world's largest collector car auction house on August 19th in California as part of its Monterey sale. It is believed that the 2001 Shelby will sell for between $150,000 and $200,000 while the 2001 Thunderbird concept will fetch between $125,000–$175,000. There will be no reserve on the cars.

Porsche Panamera designer focused on rear-seat passengers

There's no mistaking it for anything but a Porsche, but with four doors and four full seats, the Panamera is like no previous Porsche. Styled by a team of in-house designers under the direction of Michael Mauer, the Panamera is 195.7 inches long, 76.0 inches wide and 55.8 inches tall--making it slightly shorter but wider and lower than the Maserati Quattroporte, with which it shares a coupelike profile. As with all such silhouettes, "the real challenge is giving the rear-seat passengers enough headroom," says Mauer.
