Verstappen fastest in first morning of Bahrain test

Lewis Hamilton locks a wheel in the new Ferrari in the early stages of testing, with the car running aerodynamic rakes to measure the airflow across the bodywork

Red Bull's Max Verstappen ended the first morning of the first Bahrain test with the fastest time.

The test, which runs until Friday, is the first of six days at the Bahrain International Circuit this week and next as the Formula 1 teams seek to understand their new cars before the start of the championship next month.

Verstappen's fastest time of one minute 35.433 seconds, set on the medium compound tyre, was 0.169secs quicker than McLaren's Oscar Piastri, using the soft.

Headline lap times in testing are notoriously unreliable as indicators of form as the specification in which the cars are running is not made public.

That is even more the case this year after the biggest rules reset in F1 history, with new regulations for chassis, power-units, tyres and fuel coming into force.

Energy management will be a key facet of the new season, and the teams and drivers are beginning their explorations of the best way to manage the hybrid engines and their electrical components for optimum lap time.

That said, the four teams expected to be closest to the front were in the top positions, with pre-season favourite George Russell of Mercedes third fastest ahead of Ferrari's Lewis Hamilton.

Williams, who are having their first serious run with their car after delays forced them to miss the week-long 'shakedown' in Spain last month, were seventh fastest with Carlos Sainz.

The Spaniard was behind the Haas of Esteban Ocon and 18-year-old British rookie Arvid Lindblad for Racing Bulls.

The Aston Martin team, the centre of a great deal of interest with their first Adrian Newey-designed car at the start of their engine partnership with Honda were towards the back - Lance Stroll, who is driving all day on Wednesday, was more than four seconds off the pace.

Each team ran one driver in the morning session with the others drivers, including world champion Lando Norris and Ferrari's Charles Leclerc, taking over in the afternoon session from 12:00 GMT.
