No Friday test drivers in Bahrain:
After BMW confirmed that Sebastian Vettel is occupied in the Renault World Series this weekend, it has also emerged that Williams' Kazuki Nakajima will sit out his regular F1 duties while he races in the opening round of the GP2 season. Meanwhile, Spyker's original Friday plans this year were shelved partly due to the contractual tussle involving Giedo van der Garde, and Toro Rosso co-owner Gerhard Berger has ruled out nominating a test driver for this year.
