The DTM’s Balance of Performance (BoP) at the Nürburgring

In 2026, the SRO will be responsible for the DTM’s car classification for the fourth year running, following the ADAC’s long-standing collaboration with Stéphane Ratel’s organisation.

We take a look at the changes to the car classifications for you, compared with the fifth race weekend at Oschersleben.

The maximum boost pressure of the Aston Martin Vantage GT3 is being reduced by 0.03 bar, meaning the car will produce less engine power.

The BMW M4 GT3 must carry an additional ten kilograms, bringing its minimum weight to 1,310 kilograms. The maximum boost pressure is reduced from 2.49 bar to 2.44 bar.

The Ferrari 296 GT3 is permitted to reduce its weight by ten kilograms, bringing its minimum weight to 1,320 kilograms. There are minor adjustments to the engine’s boost pressure, although the maximum boost pressure remains unchanged.

The Ford Mustang GT3 must add ten kilograms; the minimum weight of the US racing car is now 1,325 kilograms. In addition, the two air flow restrictors have each been reduced by one millimetre, meaning the powerful V8 engine produces slightly less power.

The Lamborghini Temerario GT3 must carry an additional five kilograms, bringing the minimum weight of the Italian sports car to 1,330 kilograms. There are minor adjustments to the engine’s boost pressure, though the maximum boost pressure remains unchanged.

There are also slight adjustments to the boost pressure of the McLaren 720S GT3, although the maximum boost pressure remains unchanged.

On the Mercedes-AMG GT3, the lambda value has been reduced by 0.02. This gives the V8 engine more power, as there is more fuel in the petrol-air mixture in the combustion chamber.

The Porsche 911 GT3 R must carry an additional five kilograms. The minimum weight is now 1,335 kilograms.
