Lewis Hamilton crashes Mercedes during testing debut in Spain

Lewis Hamilton didn't get off to a good start in Formula One preseason trials Wednesday. Fox Sports reports, after a brake failure, the race car driver crashed his Mercedes into the wall.

Traveling at 170 miles per hour at the time of the collision, Hamilton was miraculously unhurt, climbing from the wrecked car and walking away. He's the second member of his team to go down in the trials. Teammate Nico Rosberg's car erupted in flames during a test run Tuesday, due to an electrical problem, and has yet to be repaired.

Mercedes tweeted that work continues on Hamilton's car, but in the meantime his replacement, Sergio Perez, has taken to the track.
