In 2026, there will be a lot of changes incoming for the much-loved sport of F1.
Firstly, there will be an 11th team in the paddock, with American outfit Cadillac joining the grid.

Meanwhile, there have also been changes to the technical regulations.
From 2026, cars are set to be lighter and more agile, which promises to bring closer on-track battles.
Although the new campaign is still three months away, there have been reports that teams have already found a 'loophole' within the new regulations.
According to The Race, Mercedes and Red Bull have allegedly managed to 'exploit the fuel compression limit', which could give them a huge advantage of 0.4 seconds per lap.
Currently, C5.4.3 of the regulations states: "No cylinder of the engine may have a geometric compression ratio higher than 16.0. The procedure to measure this value will be detailed by each PU Manufacturer according to the guidance document FIA-F1-DOC-C042 and executed at ambient temperature. This procedure must be approved by the FIA technical department and included in the PU Manufacturer homologation dossier."

Previously, the fuel compression ratio had been set at 18:1, and it has been reduced to 16:1 ahead of 2026.
It has been claimed that Mercedes and Red Bull may have found a away to effectively run the fuel compression at 18:1 on track, but still comply with the rules when the cars are stationary and checked by the sport's governing body, the FIA.
Aside from Mercedes and Red Bull, the likes of Aston Martin, via Honda, Ferrari and Audi are also making their own engines and are believed to be concerned about the potential loophole and it is believed that they have written a 'joint letter' to seek answers from the FIA.
As per The Race, the teams will have several options: to accept that they have missed a trick and work on a solution as quickly as possible, or they could look at challenging the rules, which could happen during the first weekend in Australia.
Speaking recently, Ferrari team boss Fred Vasseur said: "I think we have also to put ourselves on the FIA's side. I think it's also a huge challenge for them to not arrive in Australia or in Bahrain and to have someone exploiting a loophole into the regulation.
"If it's a good job on the regulations and someone is able to do a good car faster than the others, I think it's fair enough. But if it's a kind of loophole in the wording and so on, it's much more difficult for everybody - and much more dangerous for F1."
However, the report stated that Mercedes have been 'in dialogue with the FIA' to make sure their designs are within the rules.
It read: "Mercedes has been in dialogue with the FIA throughout the rules process so there is no element of it having tried to sneak something through. It has had reassurance that its interpretation of the rules is in line with the FIA so it has kept pursuing its design process."
