Last week, we got our first glimpse of the 2026 Audi Formula 1 car when it was out for filming at the Circuit de Barcelona in Spain. Another new entry this year is Cadillac, and they’ve been testing their F1 race car at Silverstone in the UK.

Cadillac will be running a Ferrari engine this year, and the recent test gave us a chance to hear the Ferrari’s 2026 regulation engine for the first time. Unlike the Audi R26, the Cadillac has a more familiar engine sound.

There has been a lot of excitement around the new F1 cars because of the new regulations. Significant changes have been made to the engine and aerodynamics.

While the 1.6-liter V6 turbo hybrid has been retained, the output of the internal combustion engine has been reduced, while that of the electric motor has tripled, for a 50-50 power split. The complex MGU-H has been scrapped. The Energy Recovery System (ERS) can now recharge the battery with twice as much energy per lap.
