Why McLaren are “slightly happier” after debut of long-awaited upgrade · RaceFans

McLaren car updates, Baku, 2023

With Formula 1’s revised technical regulations still relatively young and the budget cap now in its third year, developing effective and efficient car upgrades is even more critical for teams than ever before.

While those at the front of the field know developing their car through the season can make the difference between a world championship title or dropping down the rankings and losing millions of dollars of prize money in the process, a well-designed upgrade package can also turnaround a poor start to a season for teams further back.

In 2023, one of the teams desperately trying to claw their way further up the order is McLaren. Despite sitting a reasonable fifth place in the constructors’ standings after five rounds, equal with Alpine, it has been a difficult start to the season for the team, performance-wise.

The emphasis on car floors producing downforce through ground effect with the current generation of cars is so great that there are so many nuances and details that teams have to consider when it comes to bringing modifications to this crucial area of the car, Stella explains.

“This is also why you don’t only have to get the basic concepts right – which…
