I'm not so sure. Grosjean was lined up as Asmer's replacement if he had gone to Japan, but, as you say, I reckon he's going to be in Bucharest now. So far Grosjean hasn't tested with Hitech and it's a bit late now. I doubt if he'd want to go straight into the meeting without testing the car beforehand.
Anyone else noticed that Double R are now running seven cars in Romania, including one for a local, Doru Sechelariu? And no, I can't pronounce his last name, so Doru it will have to be.
