Mercedes reveal F1 car for new 2026 rules

Mercedes say they had a "sensible" first day's running with the car they hope will return them to the front of Formula 1 in the sport's new rules era.

Mercedes became the most successful team in history during the period 2014-21, with eight consecutive constructors' titles and seven drivers' championships in a row.

But they fell from their pedestal during the last rules set from 2022-25 and hope this year's reset will favour them.

They ran the new W17 at Silverstone on Thursday, with both George Russell and Kimi Antonelli completing time behind the wheel.

Trackside engineering director Andrew Shovlin said in a team statement: "As with any shakedown, the focus is on ensuring everything operates safely and reliably.

"We were able to get through our allotted mileage. That is testament to the hard work of everyone at Brackley and Brixworth.

"Our attention now turns to Barcelona where we will look to build on today's running and add to our understanding of the W17."

Mercedes will join the other 10 teams for the first pre-season test, which is being held behind closed doors with no independent media allowed, at the Circuit de Barcelona-Catalunya next week. Teams are allowed to run on a maximum of three of the five test days.

Mercedes start the year regarded by many as favourites as new chassis and engine rules are introduced.

Rivals fear Mercedes, along with Red Bull's new powertrains department, have found a loophole in the rules that allows them to run the engine at a higher compression ratio than defined in the rules.

This is set at 16:1 but rules stipulate it will be measured at ambient temperature. A meeting between the teams and governing body the FIA on Thursday will discuss concerns that Mercedes and Red Bull have found ways for the compression ratio to increase at higher temperatures, which would increase power output.

Red Bull engine boss Ben Hodgkinson said last week: "Any engineer that doesn't understand about thermal expansion doesn't belong in this sport, doesn't deserves to be an engineer, really.

"Understanding how materials behave in different temperatures, pressures, stresses, loads, that's literally our job."

The new Mercedes W17 has been designed to optimise what is widely regarded as the biggest regulation change in history, with new cars, engines and tyres, and the mandating of fully sustainable fuel.

Mercedes team principal Toto Wolff said: "Formula 1 will undergo significant change in 2026, and we are prepared for that transition.

"The new regulations demand innovation and absolute focus across every area of performance.

"Our work on the new car, and the long-term development of the power-unit and advanced sustainable fuels, reflects that approach."
