Lewis Hamilton backs Mercedes car for 2022, Charles Leclerc sets early pace in opening practice

Lewis Hamilton has full faith Mercedes can deliver him a car ready to challenge for a record eighth world championship after he controversially missed out last season.

Two months and 11 days after last year's controversial finale in Abu Dhabi - which saw Hamilton denied a record-breaking eighth title - F1 emerged from its winter hibernation with its first pre-season test at Barcelona's Circuit de Catalunya on Wednesday.

"Every year is exciting but this one is completely brand new," the Briton said.

"I have seen designs of our car obviously but this is the first time you get to see the other teams out there on track.

"You want to see a close eye and see why others have taken a different route. You have no idea where you stand so it is definitely exciting."

The sport has undergone the biggest overhaul of its regulations in a generation, and Hamilton was among the interested spectators outside rival Max Verstappen's Red Bull garage when the running started at 9am.

"I do hope that these rules deliver in terms of closer racing," the seven-time champion said. "It puts everybody on a closer playing field."

Asked if he felt Mercedes might not be able to provide him with a car to challenge for the championship, Hamilton said: "Why would I ever feel that way? My team don't make mistakes.

"Of course that is a risk (with the new regulations) but I trust the team. Whether it is good or bad we will work through it."

Ferrari's Charles Leclerc finished ahead of British driver Lando Norris on the opening morning in Barcelona.

Despite the technical rule-book rewrite, to some surprise, the majority of teams were able to deliver a number of trouble-free laps. Indeed, there was not one red flag in four hours of running.
