- The turmoil at McLaren deepened Tuesday when development driver Oliver Turvey missed most of testing in Bahrain with an engine leak, as Lewis Hamilton went fastest in his Mercedes. At the weekend Bahrain Grand Prix McLaren's Fernando Alonso complained he had never raced with so little power, while his teammate Stoffel Vandoorne had no power at all after engine failure prevented him even starting Sunday's race, which was won by Ferrari's Sebastian Vettel. During in-season testing on the same circuit Tuesday McLaren detected a water leak on the first lap and worked all day to repair it, completing only 17 laps and two timed runs. "I’m really grateful for giving me the opportunity to drive here in Bahrain. It’s frustrating to have had an issue this morning which cost us a lot of track time," Turvey said having waited all day to get back behind the wheel.
