The Force India team unveiled its new Mercedes-powered VJM10, which has been produced by design team led by Technical Director Andrew Green. It is the work of chief designers Akio Haga and Ian Hall, with the aerodynamics being overseen by Simon Phillips. Green says that the car has very little carry over from the VJM09. The wind tunnel work was done in the Toyota windtunnel in Cologne. The biggest change for the team was that it was able to build its chassis in-house rather than having to rely on suppliers, which meant that the team had complete control of scheduling and quality. The team continues to have backing from Diageo, but the Smirnoff branding has been replaced by Johnnie Walker.
