Paris Soir - Norris turns on the heat at sweltering Bahrain practice

It was hunt-some-shade time on a sweltering afternoon in the Gulf kingdom - 35 degrees celsius and track temperature nudging 50 degrees.

As a consequence the relevance of the opening session on the rest of the weekend will be minimal, with second practice later Friday, Saturday's qualifying and the race itself all staged at sunset and in cooler temperatures.

That was one main factor in teams using 'FP1' to give a half dozen rookies a shot as a 'Friday driver' as per the governing body's guidelines.

As a result, four-time world champion Max Verstappen, one point adrift of Norris in the driver's standings after his win in Japan last weekend, had some down time with Ayumua Iwasa taking the wheel of his Red Bull.

Dino Beganovic was handed the keys to Charles Leclerc's Ferrari.

Other new faces were Fred Vesti (in for Mercedes' George Russell), Luke Browning (Williams/Carlos Sainz), Felipe Drugovich (Aston Martin/Fernando Alonso) and Ryo Hirakawa, in for Ollie Bearman at Haas.

Williams team principal James Vowles explained the reasoning behind running Browning rather than Sainz, third to Verstappen in last year's race for Ferrari.

"It's much, much warmer than it will be so it is unrepresentative, and (Sainz) has done many hundreds of kilometres around here. It's always painful, but it is less painful to run a Friday driver here."

Browning had a scary moment with his temporary teammate Alex Albon, the pair coming close with a quarter of an hour left of the session.

The stewards noted Browning for impeding for going slowly at turn 13.

"Wow that was close" said Drugovich who had a close-up view of the incident in the Aston.

Kimi Antonelli was reporting loss of power in his Mercedes over the team radio early on with the Italian teenaged rookie, who has made such a bright start to his career, forced back into the garage, missing almost the entire session.

- 'It feels horrendous' -

Ferrari have brought upgrades to Bahrain but Lewis Hamilton was quickly complaining about lack of balance.

With tyre compounds set up for the cooler evening temperatures drivers were complaining of lack of grip.

Liam Lawson described it as "shocking" in his second run out for RB after being demoted by Red Bull.

Hamilton was asked if he wanted to have another lap before a quick return to the pits but the reply was short, sharp and an unambiguous 'no'

"It feels horrendous, mate," said Hamilton.

Alpine, the only team arriving at this desert track still pointless, will have been encouraged by Gasly's effort in jumping to lead the timesheets late on.

But Norris quickly asserted control with a lap of 1min 33.204s, from Gasly at 0.0238

Seven-time champion Hamilton's afternoon improved as he ended up with the third quickest time after switching to the faster softs.

Yuki Tsunoda replaced Lawson as Verstappen's teammate last weekend and the Japanese driver came in ninth ahead of McLaren's Oscar Piastri, winner in China.
