McLaren heads into the 2026 Dutch Grand Prix with Lando Norris on pole position but with a clear concern over the MCL40’s rear tyre degradation across a full race distance. The Woking team has made impressive technical progress and now appears capable of matching Mercedes over a single lap, yet the behaviour of the rear axle during the Sprint showed that its biggest Zandvoort test may come over the longer Sunday race.
McLaren thoroughly deserved its pole position, even though the rear of the MCL40 was still not behaving perfectly. The rear axle has a tendency to become overloaded and lose grip, creating a potential degradation problem that could cost both cars performance as the stints develop.
McLaren MCL40 development has transformed its competitiveness
Mercedes and McLaren now appear closely matched in terms of outright qualifying performance, as demonstrated by the results across Zandvoort’s two qualifying sessions. The MCL40 continues to improve rapidly, particularly since McLaren identified a productive development direction in Hungary through changes that included work around the diffuser.
The progress continues a technical recovery that has gathered momentum since Budapest. McLaren’s recent development programme has already delivered clear gains, although Andrea Stella has previously cautioned that the MCL40’s development will face further tests at upcoming circuits.
The car naturally still has weaknesses that McLaren’s engineers are working to reduce, but the team has so far done an excellent job of maximising its execution at Zandvoort. Several changes were made compared with Friday, when pole position had escaped by the narrowest of margins.
More generally, both Mercedes and McLaren have been configured with a greater emphasis on single-lap performance. That has also made life harder for Ferrari in qualifying. The Italian team endured several difficulties earlier in the weekend and, unlike McLaren, was unable to optimise its performance as effectively with only one hour of free practice available to work on the set-up.
McLaren rear end still not perfect despite set-up changes
Looking specifically at McLaren’s balance, the picture across the weekend has been positive but far from flawless. Even during the second qualifying session at Zandvoort, the MCL40 did not look completely settled.
In some sections, particularly at low speed, the rear appeared to lose grip and forced the drivers to correct small snaps of oversteer. That weakness contrasts with McLaren’s exceptional performance through the faster corners, where the car can rely much more heavily on the aerodynamic load generated by its latest package.
The trend fits with the characteristics already exposed by McLaren’s recent upgrades. The team has made a major step at the rear of the car, including the developments introduced for Zandvoort and its unusual new rear-wing solution, but slow-speed rear grip remains an area requiring attention.
Andrea Stella explained the changes McLaren made before qualifying: “We made various changes before qualifying, with the aim of improving grip in the low-speed corners and reducing the load on the rear axle, in order not only to improve performance but also to help tyre degradation.”
The MCL40’s handling was therefore not especially clean. Ferrari’s SF-26 appeared more composed in that respect, even though it was ultimately slower.
McLaren’s main limitation remained the rear axle, which tended to become overloaded before losing grip. The problem was particularly noticeable through the more technical sections of the circuit. In the faster corners, the situation was better because the MCL40 could exploit the strong aerodynamic load generated by the car.
McLaren targets rear tyre degradation before Dutch GP race
Stella’s explanation makes McLaren’s approach relatively clear. The team has attempted to move the mechanical balance further forward, asking more from the front axle, which has responded well, in order to protect and preserve the rear.
That links directly to the MCL40’s most significant concern heading into the Grand Prix. Excessive degradation had already emerged during the Sprint and became something McLaren had to manage as the race developed.
Over a longer stint, the rear tyres were probably experiencing small slides that gradually increased physical tyre degradation rather than purely thermal degradation. The crucial task in the Grand Prix will therefore be to preserve the rear tyres as the laps accumulate.
Tyre wear is expected to be particularly important around Zandvoort, where Pirelli’s Dutch GP tyre outlook has placed degradation and compound choice firmly in focus.
According to Stella, the effect of tyre degradation can be worth “up to one tenth per lap”. Over a long stint, even a relatively small difference of that size can therefore develop into a significant performance loss.
Mercedes HPP work helps McLaren close another important gap
Beyond the aerodynamic and mechanical work, McLaren has also done an excellent job alongside the Mercedes High Performance Powertrains engineers at the circuit.
The team has improved both energy regeneration and deployment, allowing the MCL40 to challenge Mercedes in an area where the customer team appeared much further behind at the beginning of the season. That represents another important step in McLaren’s wider technical recovery.
Power-unit optimisation has become particularly important under the 2026 regulations because lap time depends not only on outright engine performance but also on how efficiently electrical energy is recovered and deployed around each circuit. McLaren has steadily improved in this area while continuing to develop the aerodynamic package.
The result is a car that can now fight Mercedes for pole position and has become increasingly competitive as the season progresses. Yet the Sprint provided an important warning: outright pace will not necessarily guarantee the same advantage over a full Grand Prix distance.
For Norris and McLaren, the priority on Sunday will therefore be to combine the speed that produced pole with enough rear tyre management to maintain that performance deep into each stint. If the set-up changes introduced after the Sprint have reduced the MCL40’s tendency to overload its rear tyres, McLaren may have the package to convert its remarkable technical recovery into another victory. If not, degradation could reopen the fight behind.
