Red Bull lookalike and McLaren woes: F1’s 2023’s cars analysed ahead of season start [Video]

Last year’s regulation changes were the biggest aerodynamic overhaul Formula One experienced for decades. This year’s changes, in contrast, are just a few tweaks here and there.

The main differences relate to the floor. With teams experiencing varying degrees of porpoising and bouncing throughout 2022, the minimum height for the outer-edge of the floor has been raised by 15mm. This is, in effect, to help the teams help themselves – or more accurately their drivers – and to counteract the porpoising.

The ‘throat’ of the under-floor has also been raised by 5mm to help make the downforce more stable or benign and less peaky or unstable.

The roll-over bar has also been changed, with a more rigorous FIA strength test in place, in the wake of Guanyu Zhou’s horrifying high-speed upside-down crash at Silverstone.
