Red Bull will cover their cars with photographs of supporters at the British Grand Prix in July in a bid to raise $1 million for a spinal injuries charity, the Formula One team said. It invited fans to make a minimum donation of 10 pounds through their Web site (www.redbullf1.com) in exchange for having their photograph on either Briton David Coulthard or Australian Mark Webber's race car instead of the usual corporate logos. "It's where I get the most support from my fans so this year having them literally on the car with me is a fun idea and a nice way for me to pay them back for their support over the years," said Coulthard.
