McLaren is testing this week for the first time at the Bahrain International Circuit. The test team has set-up base at the Grand Prix track for a six day session. All the team’s main competitors are also present at the Bahrain test, which marks the final on track development opportunity before the start of the 2007 F1 season. Work for Lewis and Pedro today focused on final sign-offs on elements of the MP4-22 package, such as software, as the team ran the Melbourne spec of the MP4-22 for the first time.
