The new Racing Bulls livery is... something
Most are out there on the hard tyres. Verstappen, Hadjar, Lindblad and Bottas have the mediums fitted.
Both Aston's have been out on track, but are now both back in.
Take a look at Red Bull's new rear wing.
Antonelli has now gone top with a 1m30.079s from Norris.
Interesting watching the Norris onboard a few moments ago. There was evident superclipping towards the end of the back straight, but it didn't seem as sudden as in previous races.
Let's wait and see what happens in full qualifying attack later today.
Leclerc had a big slide into Turn 11, like Hamilton.
Aston Martin has provided a brief update as to why Alonso and Stroll are still in the pits.
"Both cars' running is delayed due to a power issue in the garage."
Some trouble for George Russell:
"It's making a noise like a steam train. I don't know what it is." He even gave us some steam train sound effects!
Norris goes quicker with a 1m30.335s from Verstappen.
Red Bull has debuted its flippy rear wing, like the one Ferrari used. And it's a pretty big space it opens up on the rear wing.
Bortoleto's had a bit of a spin but he's fine and back underway.

We've just had our first look at the Audi on track. With everything that's gone, it's easy to forget that Allan McNish, ex-F1 driver and Le Mans legend, has taken on a new senior role in the wake of Jonathan Wheatley's departure.
