Interstingly in gary Anderson's supergrid in autosport(a measure of outright speed) Grosjean is well ahead of Kimi. It goes like this. Lewis is a whole car and a quarters length ahead. Then the cars are very close and the order is Vettel, Grosjean, Rosberg, Button, Alonso, Webber, Raikonen, Schumacher, Maldonado. Bit bigger gap then Perez, Kobi, Hulk, Di Resta, Massa. Bit bigger gap then Senna, Ricciardo. The rest quite a bit back.
Some surprises there. Big gaps between team mates except the Force Indias and the Saubers. But Grosjean clearly the faster driver at Renault yet Kimi ahead. It kind of confirms its those earlty race incidents that have hit him hard regarding point scoring.
