F1 testing wrap: Mercedes on top and Fernando Alonso crashes

BBC F1 pit lane reporter Lee McKenzie rounds up the stories from Formula 1's second pre-season test in Barcelona.

The test ended on a sour note, with Fernando Alonso crashing his McLaren into a wall and being airlifted to hospital with concussion.

Lotus driver Romain Grosjean set the fastest time outright at the Circuit de Catalunya, but Mercedes' Nico Rosberg was just two tenths adrift of the Franco-Swiss driver's time despite using the slower, medium-compound tyre.
