The new Alfa Romeo C43 Formula 1 car
appeared without the radical serrated edge floor seen on launch renders when it made its track debut in Barcelona on Friday.
Valtteri Bottas gave the car its first track mileage on a filming day at the Spanish GP venue, with Guanyu Zhou sampling it in the afternoon.
It was the first appearance of the real car, previously seen only in show car form and in renders, and also the first track running for any 2023 F1 machine.
The Swiss team has paid particular attention to the rear end of the car, which has a new gearbox and a very different rear suspension and cooling layout compared to the C42.
However, the major focus for all teams even at shakedowns and in Bahrain testing will be the impact of the new floor regulations, which have been introduced to prevent the porpoising that was such a feature of the 2022 season.
The C43 is running a notably different floor in Spain compared to that seen in the renderings and on the show car, which had a very distinctive edge, featuring cut-outs.
