Red Bull, Ferrari, and McLaren have all brought small upgrades to the British Grand Prix as they hope to reel in championship-leaders Mercedes.
The W17 has not been armed with fresh upgrades this weekend for the British Grand Prix, whereas its rivals the RB22, the SF-26, and MCL40 all have small packages for the Sprint weekend at Silverstone.
McLaren has delivered two upgrades, focusing on a new front brake-duct design and a revised floor to "improve the flow physics and gain in overall efficiency."
For Red Bull, a simple rear winglet has been added to "improve load characteristics and stability" around the rear wheel bodywork assembly area.
Ferrari's upgrade has been focused around increasing cooling at the rear and also increasing local load via a "lower deflector redesign and winglet loading optimisation, maximising aerodynamic efficiency."
Elsewhere, Williams has brought a new front-wing design to boost performance, with Racing Bulls delivering a new floor and diffuser to improve airflow around the floor, whilst a new forward deflector at the rear is intended to improve "local flow conditioning."
The only other team to bring an upgrade is Haas, with a new rear wing, focusing on a "comprehensive" revision of the flap geometry whilst trying to maintain the overall aerodynamic efficiency.
