Norris, Verstappen, Sainz, Russell, Perez, Hamilton, Ocon, Albon, Ricciardo and Magnussen.

Some of Alonso's front wing is on the track so race control have thrown out the red flag.

He goes 0.3s clear of Sainz at the top of the timesheets. Both Red Bulls on the softs though.

Sainz goes quickest of all with a 1m14.572s on the mediums, a tenth ahead of Perez, who is on the softs.

"The car is horrendous for now," Leclerc reports over team radio.

Verstappen, Russell, Sainz, Hamilton, Norris, Perez, Leclerc, Ocon, Tsunoda and Albon.

A 1:15.424 lap puts Max at the top.

Sky's Bernie Collins questions if Ferrari are running aero tests, so are intentionally limiting the car's power briefly.

Carlos Sainz reports 'no power' via team radio.

A change to his steeling wheel might have sorted it.

George Russell leads Max Verstappen, then it's Esteban Ocon, with nine minutes of the session gone.

Ollie Bearman in the Haas is one of the first out on track.

Ferrari and Red Bull have brought multiple updates.

FERRARI

Rear Wing - Circuit specific - Drag Range. Higher Downforce Top Rear Wing and Lower Rear Wing designs. Introduction of more loaded Top and Lower Rear Wing main and flap profiles. Allowing different modulations, this update extends the car polar in order to offer more possibilities on mid/high downforce tracks.

Coke/Engine Cover - Performance - Flow Conditioning. Increased Sidepod / Coke undercut. The new bodywork features a reworked undercut that improves flow quality over the floor edge and towards the back of the car.

Floor Fences - Performance - Flow Conditioning. Redistributed floor fences camber. Aim of redistributing front floor fence loading was to improve flow quality delivered to the rear floor / diffuser.

Floor Body - Performance - Flow Conditioning. Lowered front floor roof. Working in conjunction with the updated front floor fences arrangement, with the objective of improving flow quality towards the back of the car.

Floor Edge - Performance - Local Load. Rearward floor edge volume increased. This minor geometrical update is an optimization around the improved flow energy coming from upstream, returning local load gains whilst controlling the vorticity release in the diffuser.

Diffuser - Performance - Local Load. Reworked diffuser / boat / keel expansion. Benefitting from tidier upstream flow structures, the diffuser expansion, together with boat and keel volumes optimization, has allowed to extract more local load gains 7 Halo Performance.
