"An agreement might be struck with Belgium’s Kronos Racing (the private tam that ran the Citroen Xsara of Sebastien Loeb to a World Rally title a few years ago) with engines supplied by Cosworth."
"Subaru and Cosworth would work together to develop a four-cylinder, turbocharged, 1.6-litre boxer engine."
"Subaru has lodged an official entry in the FIA World Touring Car Championship for 2012 to race Imprezas. "
Will they have to lose the AWD and turbo though?
