Sauber's 2025 F1 launch car to be auctioned

The Formula 1 car Sauber will use to reveal its 2025 livery at F1's first-ever collective launch event at the O2 arena will be auctioned off.

All 10 teams will unveil their 2025 liveries during the first-of-its-kind event on February 18 with teams expected to use show cars rather than their real-world 2025 challengers.

There will be team-by-team reveals including each team's 2025 drivers - Nico Hulkenberg and Gabriel Bortloleto for Sauber - and key team personnel - CTO and COO of Sauber Mattia Binotto - on stage alongside the new livery.

The show car Sauber will use will be available to the highest bidder in an exclusive online auction hosted by F1 Authentics.

The showcar has been manufactured by Memento Exclusives, which manages F1 Authentics and is based within F1's 'Motorsport Valley' near Silverstone.

Memento Exclusives has produced many of Sauber's previous launch cars, assisted by computer aided design and data for authenticity.

The lot will open on February 11 one week prior to the O2 event, allowing collectors to start bidding before the reveal.

The show car is the first major item of F1 Authentics' upgraded auction site with the promise of further show cars, simulators, race wear, race helmets and ex-F1 race cars.

Championship-winning Brawn for sale

One of three chassis used in Brawn GP's championship-winning 2009 season will be up for sale at the Miami Grand Prix in May by Bonhams Cars.

The Brawn GP chassis 001/01 was used by Rubens Barrichello for the first 13 rounds of the 2009 season before he switched to another chassis after a crash in Singapore.

That chassis ended up with Jenson Button due to a clause in his contract after he left for McLaren and remained in his collection until he sold it in 2024.

Button's championship-winning 001/02 chassis went to team owner Ross Brawn and the 001/03 chassis to engine supplier Mercedes, which took over the Brawn team ahead of the 2010 season.
