Renault introduces R23B

Renault has revealed that the team will race a significantly modified R23 at Silverstone. The R23 will become the R23B this weekend."We will have a major bodywork update on the car," Gascoyne said. "We have decided to christen this R23B as it groups together a significant number of detail modifications into a single package, which had always been planned for Silverstone. Following a positive test in Barcelona last week, we expect it to bring a definite gain on the stopwatch".Renault isn't the only team that comes with serious modifications to its car, and it is still to be seen what step forward can be made.
