Mercedes appear to have finally hit their stride in the 2018 Formula One season after Lewis Hamilton claimed a comfortable victory at the Spanish Grand Prix.
The defending world champion had to wait until the fourth round in Azerbaijan to pick up his first win of the campaign, but an imperious drive in Barcelona made it back-to-back victories for the Briton.
After making his pole position stick into turn one and waiting patiently during a six-lap period under the safety car, Hamilton rapidly stretched his lead over championship rival Sebastian Vettel, who had overtaken Valtteri Bottas at the start.
The safety car's appearance was brought about by a huge crash that saw Nico Hulkenberg and Pierre Gasly wiped out by a spinning Romain Grosjean on the opening lap.
With Vettel some way off Hamilton's pace and Kimi Raikkonen forced into retirement by an engine problem, the biggest challenge to Mercedes threatened to come from Red Bull’s decision to adopt a one-stop strategy.
But Mercedes, who pitted some 10 laps earlier than the two Red Bulls, managed their tyres to the finish, while Vettel's hopes were futher dashed by his own slow second stop under the virtual safety car.
That left the German to settle for fourth, as Bottas and Max Verstappen joined Hamilton on the podium.

Daniel Ricciardo was fifth, ahead of Kevin Magnussen, Carlos Sainz, Fernando Alonso, Sergio Perez and Charles Leclerc.
The result sees Hamilton stretch his lead at the top of the drivers' standings to 17 points after five races.
