Ferrari pair Kimi Raikkonen and Sebastian Vettel were third and fourth, about a second slower than Hamilton.
Red Bull driver Max Verstappen, who won the race last year, and Daniel Ricciardo were next, within 1.6 seconds of Hamilton.
Again engine failure for McLaren with Fernando Alonso – he has not even completing a lap at his home circuit in Barcelona before the Spaniard’s Honda engine blew.
A puff of smoke surrounded the double world champion when his McLaren spun out of a turn and into the gravel at the start of the morning session at the Circuit Barcelona-Catalunya.
McLaren’s team radio told him to “stop the car, stop the car, engine problem” as a pool of liquid dripped from the underside of the vehicle.’
“It’s a question for Honda not for me, Engine. Alonso told SKY F1
“The engine blew up after one corner. It’s the way it is, we miss the first session. I’m sorry for the fans.
“Hopefully the second session can be better and we recover this time.”
Alonso and McLaren are having a wretched 2017. After showing some progress with its Honda engine last year, the team has taken a huge step back with neither Alonso nor new teammate Stoffel Vandoorne yet to score a point.
“It’s tough but it’s tougher for McLaren, who bring updates trying to find a millisecond here and there and we cannot even run,” added Alonso. “Hopefully we find a solution and can run in P2.”
Disappointed Alonso decided to go back to his hotel soon after his car engine failure and he posting on Instgram playing a spot of tennis. His manager confessing that “he hopes he’ll come back”.
who could blame him. Finishes Indy 500 and straight to Wimbledon.
