Norris leads team-mate Piastri in Austria practice

Lando Norris failed to finish the last race in Canada after crashing into team-mate Oscar Piastri

Lando Norris led team-mate and title rival Oscar Piastri to a McLaren one-two in Friday practice at the Austrian Grand Prix.

Norris was 0.157 seconds quicker than Piastri, with Red Bull's Max Verstappen third fastest, 0.318secs off the pace.

Aston Martin's Lance Stroll took fourth place, ahead of Ferrari's Charles Leclerc and the Mercedes of George Russell.

McLaren, Red Bull and Ferrari all have upgrades to their cars this weekend.

McLaren have new front suspension shaping that is aimed at working with a new front wing that was first tested at the last race in Canada.

Red Bull have a new floor edge. Ferrari, for whom Lewis Hamilton was 10th fastest, have a completely redesigned new floor, their first upgrade since Bahrain in April.

Red Bull's Yuki Tsunoda was seventh, while Sauber's Gabriel Bortoleto, Aston Martin's Fernando Alonso and Hamilton completed the top 10.

The race-simulation runs later in the session provided a complex picture, as the leading drivers chose different tyre compounds.

On the medium tyre, Mercedes' Kimi Antonelli, 11th fastest on the list of headline lap times, appeared to have a slight edge over Norris and Leclerc.

Verstappen was slightly quicker than Hamilton, both using the soft tyre, while Piastri did his long run on the hard tyre.

In the first session, there was an impressive F1 debut by McLaren's Alexander Dunne.

The 19-year-old Irishman, leading the Formula 2 championship this season and having his first taste of an F1 car on a grand prix weekend, took over Norris' car and ended up fourth fastest, just 0.069secs slower than Piastri.

Dunne had a test in McLaren's 2023 car in Austin, Texas, last week in preparation for his run at the Red Bull Ring, but it is rare for a young driver to be so close to a regular racer in such circumstances.

As such, Dunne's performance can be seen to be comparable with Norris' similar pace when he drove in practice at the 2018 Italian Grand Prix, alongside then McLaren driver Alonso.

Alex Dunne is in his first season in Formula 2
