Lewis Hamilton led the way from his Mercedes teammate Valtteri Bottas in the first free practice session of the Spanish grand prix.

The ninety-minute session was topped by Hamilton’s 1:21:521 which was  29 thousands quicker than Bottas’ P2 time. The two Ferrari’s followed in third and fourth with Raikkonen setting a 1:22:456 ahead of Vettel, on a 1:22:600.

Early in the session Fernando Alonso’s McLaren spectacularly expired after only a half a lap out of the pitlane. The team reported a rather obvious engine failure while Alonso left the circuit for a round of tennis. The Renault of Sergey Sirotkin suffered a water leak which limited his running in the session to only ten laps.

While several teams utilized the session to evaluate new upgrades and updates to their cars it remains to be seen what sort of impact these new updates will have on the pecking order.
