F1 2026 rule details emerge: Smaller cars with 40 per cent less downforce
As the year 2026 approaches, the formal finalization of regulations is still pending. However, a report by the reputable German publication AMuS has unveiled some changes on the chassis side. While much of the public discussion has focused on the new engines, it is worth noting that Mercedes, Ferrari, Renault, Honda, Red Bull-Ford, and Audi are all set to participate in the grid. In line with the automotive industry’s shift towards electric power, the MGU-K unit will now be three times more powerful than before, increasing from 120 kW to 350 kW. The MGU-H has been completely removed for the 2026 rules, resulting in cost reduction. The cars will run on 100% sustainable fuels, with a 50-50 split between internal combustion engines and electrical power. Additionally, the aim is to reduce fuel usage to 70 kilograms in 2026, compared to the current 100 kilos. The FIA’s focus is also on making the cars lighter and smaller. The current weight of F1 cars is around 798kg, with expectations that the new engines and “countermeasures” will push it past 800kg. The initial step is to reduce the weight by a minimum of 20 kilograms, with further reductions targeted throughout the regulation cycle. Other changes include reducing the width of the cars from 200cm to 190cm and shortening the wheelbase from 360cm to at least 340cm. Consequently, there will be a 40% decrease in downforce.
