The German team will modify the gear ratios of the R26 to correct a first gear that was too short and an eighth gear that was excessively long.
The Italian Grand Prix will not only be a speed test for the cars, but also a test bench for the technical solutions that some teams have been developing for months, Audi is one of them. The German team will arrive at Monza with a significant modification to its gearbox, an update that was decided practically six months ago and has required 24 weeks of waiting for its manufacture.
The problem was detected during the first tests of the season, the simulations carried out before the debut had not accurately reflected the needs of the new power unit, once on track the team found that first gear was too short and eighth, excessively long. A misadjustment that affects performance and could not be corrected as quickly as an aerodynamic modification.
The complexity of the operation explains the long waiting period, modifying gear ratios is a costly and technically demanding process that also depends on an external supplier for the manufacture of the new gears. Audi has had to wait 24 weeks to have the components available, which has delayed the introduction of the new configuration until the Italian round.
The choice of Monza is no coincidence, the Brianza circuit, with its long straights, is one of the most demanding tracks on the calendar for power units. Energy management and propulsion system efficiency will be decisive, making this weekend the perfect stage to debut the new configuration. Audi's goal is clear: to better exploit the V6 engine's operating range.
By reducing the total interval between first and eighth gear, the engine will be able to stay longer in the range considered most efficient. This aspect becomes especially relevant with the characteristics of the power units introduced in 2026. The modification is not expected to mean a significant leap in gross performance, but it will allow correcting a compromise with which Nico Hülkenberg and Gabriel Bortoleto have had to live since the start of the season.
One of the aspects that will have to be closely monitored will be the behavior at starts, Audi has worked intensively on this front in recent months, especially after the difficulties that arose in the first part of the championship. The slightly smaller turbocharger introduced in Barcelona already contributed to improving the situation, as did the drivers' work in managing the procedure. The new first gear, longer than the one used so far, will change some reference points.
Financially, the operation has been demanding and has required the green light from the department in charge of managing the budget cap. Audi's situation is not unique, McLaren encountered a similar problem after the data provided by Mercedes HPP did not match what was observed on track, however the Woking team decided not to intervene in the transmission ratios to allocate those resources to aerodynamic development. Audi, on the other hand, has opted for mechanical correction, trusting that the benefit in power unit management will compensate for the investment.
Monza will deliver the verdict on the effectiveness of this modification, a change that Audi hopes will mark a before and after in its season.
