One team uncertain about engine for F1 2026

After walking around the 2024 Formula 1 paddock, you will see this year (once again) only four engine manufacturers will supply engines for Formula 1 cars.

Mercedes, Ferrari, Honda and Renault. Together they supply all 10 teams with a power unit. Mercedes even supplies engines to three other teams: Aston Martin, McLaren and Williams.

In 2026 the regulations for the chassis and engine of F1 cars, among other things, will change. This is being done to make the sport more attractive to new engine manufacturers and to reduce the differences between teams.

The 1.6 V-liter engines will remain, but the MGU-H will disappear. This is a system in the engine that converts wasted heat to electrical energy. To make up for this loss, the hybrid energy of the MGU-K will be increased to 350kW, which should keep the power of the cars the same.

The first effects of the new rules are immediate, because in 2026 at least six engine suppliers will be represented in F1 - it's highest in over 10 years. Audi makes its entrance and we will also start to see Ford, who will Red Bull on the Ford/Red Bull Powertrains venture.

All the current teams on the grid are already certain which engine they will run with from 2026, except one. Haas has been running a Ferrari-supplied engine since it entered F1. There is therefore a good chance that this will also be the case from 2026, but no certainty has yet been given.

We may also see a new team on the grid in 2026 if Andretti gets the green light. The American team would prefer to do so by partnering with engines from Cadillac, but parent company General Motors has indicated that this will not be possible until 2028. Until then, Renault would like to help Andretti as per the regulations.
