F1 2026 Regulations: What has happened to the MGU-H?
The 2026 F1 season brings a host of new regulations, including changes to aerodynamic car design and power units, causing confusion among fans unfamiliar with the new ‘F1 jargon.’
The new power units maintain the 1.6-litre V6 turbo hybrid engine configuration introduced in 2014 but with a tripled emphasis on electrical energy output, leading to the elimination of the MGU-H component.
The MGU-H, which converted thermal energy into electricity and controlled turbocharger speed, has been removed due to high production and maintenance costs without significant power gains, as well as its incompatibility with hybrid road cars.
The absence of the MGU-H has led to challenges such as turbo lag and difficulties in starting and launching the cars, requiring drivers to adapt their racing techniques to manage battery capacity and energy recovery systems.
Teams like Red Bull and Aston Martin will use different power units in 2026, with changes in partnerships and the arrival of new manufacturers like Audi marking a significant shift in engine supply dynamics in the sport.
