When Components 1’s latest era of automobiles turns up in Barcelona on the finish of January for the primary collective shakedown, few of them are anticipated to fulfill the FIA’s 2026 minimal weight.
As a part of its 2026 guidelines overhaul, which incorporates a departure from a reliance on the ground-effect as nicely a a lot greater electrical element to the hybrid engines, a decreased weight restrict has lengthy been mooted as a key efficiency differentiator.
The minimal automotive weight for F1’s new guidelines period has been set at 768kg, 32kg down on the 2025 restrict of 800kg. That comes regardless of a rise in battery weight to accommodate a close to 50-50 break up of inside combustion energy and power derived from the expanded MGU-Ok system, though decreased automotive dimensions and narrower tyres ought to assist shave off some weight. From 2026 the automobiles’ most wheelbase has been decreased by 200mm to 3400mm and the width has been minimize from 2000m to 1900mm.
The FIA is eager to slash automotive weight even additional, after it ballooned by greater than 200kg over the previous twenty years. However groups had been nonetheless puzzled when the aggressive weight discount was first introduced, bracing for one more key battleground to open up for 2026 alongside aerodynamics, energy unit design and engine deployment.

Quick ahead a number of months, and by the flip of the yr a number of workforce representatives nonetheless imagine the 768kg restrict will probably be formidable for many groups to realize any time quickly. Given each 10kg of extra weight quantities to round three tenths per second on the monitor, that would make a major influence on the early pecking order.
“It will be good to seek out out from others the place they’re, however I feel most will probably be obese,” Williams workforce principal James Vowles instructed Motorsport.com in Abu Dhabi. “That is the straightforward details behind it. It is a very aggressive goal, but it surely’s manageable. It is a quantity that I can see that will probably be in a smart place in 5 to 10 months after the rules come out, so I am relaxed [about it].”
Mercedes’ Andrew Shovlin additionally concurred the load challenge continues to be a serious subject. “Weight is a big problem,” he mentioned. “The restrict wasn’t set by summing parts, it was merely imposed. It’s less expensive to take away weight earlier than components are made than after automobiles are constructed and inventory is in circulation.
“Groups in earlier rules had been 10 to 20kg obese initially, which is expensive and interferes with improvement. Our goal is to start out as near the restrict as attainable.”

Talking to Motorsport.com earlier in 2025, the FIA’s single-seater director Nikolas Tombazis was hopeful the governing physique may minimize automotive weights even additional in future rules. This was one motive behind final yr’s exploratory talks over a return to naturally aspirated energy models with a a lot smaller ERS aspect in 2030 or past. “We might all just like the automobiles to be loads lighter,” Tombazis mentioned. “Among the options being mooted [in terms of future powertrains] would result in considerably lighter automobiles, which is what everybody would really like. It is a trade-off between financials, technological freedom and the way cutting-edge Components 1 is, environmental issues, and pleasure.
”We will go in direction of negating a few of the dimensional features of automobiles, but it surely must be attainable to return again to a automotive that’s easier than it’s now.”
Any strikes to cut back automotive weight are being applauded by F1’s drivers, who’ve lengthy lamented excessive automotive weights that make their equipment sluggish to drive in low-speed corners.
“I feel the [current] automobiles are positively too heavy, they’re too massive and the bottom impact and the journey heights we’re racing are usually not actually enjoyable to drive,” mentioned Aston Martin’s Fernando Alonso, who debuted in 2001 when the automotive weight was under 600kg.
Mercedes’ George Russell added: “It’s getting in the suitable path, making the automobiles smaller, lighter.”
