QUALIFYING ANALYSIS: Slipstream versus clean track in Spielberg

Qualifying in Spielberg is always an interesting session that is split by hundredths of a second, and we saw that once again in 2026.

What was interesting was the decision-making process from all the teams and drivers about where and when they opted to put their cars out on track.

As in Barcelona at the previous round, a slipstream is valuable, moreso around the Red Bull Ring with three DRS zones around the lap which can count for a large chunk of time.

But it was Noel León that took pole, as the Campos Racing driver chose clean air and an empty track over a tow.

So how was the Mexican driver able to take pole without a tow?

SECTOR 1

A 1:15.544 was enough for León to secure top spot on Friday, with next-best Alexander Dunne logging a 1:15.673 - 0.129s down on the pole time.

Analysing the sector times from each of their fastest laps, it’s easy to see the impact of the slipstream in Sector 1.

Dunne’s fastest lap was achieved with the best overall split through the opening sector of the Qualifying session, 18.851s giving him a purple S1, just under a full tenth of a second better than León managed on his pole lap.

The 287.6KM/H of the Rodin driver compared to a 285.7KM/H for León shows a narrow advantage, but an important one, nonetheless.

SECTOR 2

The second sector of the lap begins with uphill braking into the tight right-hander of Turn 3. Corner exit is critical as it leads into the next DRS zone and the long downhill blast to Turn 4.

Drivers then must tackle a deceptively tricky downhill braking zone at T4, with another important traction zone leading to Turns 5 and 6 before completing the second sector.

Here, León pulled time back overall versus Dunne, who actually has the slowest middle sector time of the top trio in Qualifying when bringing Nikola Tsolov into the equation also.

33.346s for the Irishman compares to a 33.287s for Tsolov and a 33.221s for León. The latter’s lap was of course unimpeded by anyone else after Campos put him out with half the session to go on an empty circuit.

Tsolov was following the TRIDENT of John Bennett, while Dunne was in the queue directly behind the Bulgarian.

While León did achieve the fastest final sector of the session, it was the middle sector where he made the most difference compared to Dunne and Tsolov.

SECTOR 3

With a purple final sector, León closed the lap with a tidy end to the lap. He did it without having to worry about dirty air from a car ahead which may have counted for around half a tenth of a second.

But the deficit in time following the opening two sectors was too much for his closest challengers to overturn in the final third of the lap, and the Campos driver was able to sit in the pitlane and celebrate a maiden Formula 2 pole position.

Upon reflection, Dunne said post-Qualifying that the balance of his Rodin was more optimal without a driver directly ahead to take advantage of slipstream.

“I did run one by myself and then I did my best lap behind Nico. Actually, doing it by yourself was probably more beneficial. I think the balance of the car and the feeling I had in clean air, I felt a lot more comfortable than when I was following. 

“So something obviously has changed this year because it's quite rare that clean air is quicker here. Noel did a very good job of maximising that with a different strategy to everyone else and in the end, it paid off.”

Something for the teams to reconsider for their next visit to Spielberg.
