Ken Block signs for Ford and the WRC

Ken Block – who became a YouTube sensation with his gymkhana stunt series ¬– has ended months of speculation by confirming he’ll compete in the 2010 World Rally Championship – switching his Subaru Impreza for a Ford Focus, while he'll also rally a Fiesta in the US. The Monster energy drink-backed deal will form a key part of Ford’s plan to market its hatches in America, and follows last year’s Pikes Peak Fiesta. It’s a tentative start for Block, who’ll be competing in select rounds of the WRC championship – Mexico is believed to be the first – to hone his skills.

But the photos of the V12 Vantage Roadster we had at the weekend were much more appealing; a white V12 Vantage Roadster obviously on an official photoshoot in appealing London locations.
