Technical updates: 2023 Japanese Grand Prix

McLaren and AlphaTauri continue refining their latest upgrade packages with new additions at the Japanese Grand Prix.

Having brought a major update to the last race in Singapore, both teams have introduced further parts at Suzuka, with McLaren bringing a fresh beam wing that is circuit-specific but also modifying its sidepod inlets. Oscar Piastri also receives the full raft of upgrades that were only on Lando Norris’ car last weekend.

For AlphaTauri there are changes to the rear wing endplates as well as the rear view mirror, with the latter focused on drag reduction.

There are no new parts at Red Bull but Ferrari looks to continue its recent good form with a fresh change to its floor, featuring a complete revision of the topology designed to provide an efficiency increase.

Mercedes has a small rear wing endplate addition for added downforce, while Aston Martin has a smaller front brake duct inlet due to the cooling requirements of Suzuka, and Williams has reduced the height of its innermost floor fences to change both local downforce and airflow rearward of that point.

Alpine, Alfa Romeo and Haas also do not have any new parts submitted in Japan.
