Aston Martin critically tight on spare parts at Spa ahead of key upgrade

Aston Martin is facing a race against time at Spa-Francorchamps, with the team's ambitious push to transform its struggling AMR26 contender creating an uncomfortable shortage of spare parts.

The Silverstone-based outfit is preparing to unleash a heavily revised version of its 2026 car at next weekend's Hungarian Grand Prix, a major upgrade package that represents a crucial attempt to escape the lower reaches of the Formula 1 grid.

But while the team is chasing a much-needed performance breakthrough, the aggressive development timeline has left Aston Martin walking a fine line heading into Belgium.

With major changes planned across the car—including revisions to the rear suspension, nose and aerodynamic surfaces, alongside a significant weight-reduction effort—every resource has been focused on ensuring the upgraded machine arrives as competitive as possible.

That determination, however, has come with a risk.

Aston Martin's million-dollar question

By delaying final production decisions for as long as possible in pursuit of maximum performance gains, Aston Martin has pushed its manufacturing schedule to the limit. The result is uncertainty over just how many replacement parts will be available when the new package makes its track debut.

Speaking ahead of this weekend’s Belgian Grand Prix, chief trackside officer Mike Krack admitted the question of whether both cars will have sufficient backup components remains one of the team's biggest concerns.

"Everybody works flat out to get the parts, to get the cars ready," Krack said.

"It is a big undertaking if you decide to do it like that, because you always try to push the deadlines as far as you can.

"So it's a big effort going on at AMRTC [Aston Martin's factory] at the moment, and I'm a positive thinker, so I think we will have two cars ready to go. Now I don't think we will have five spares of each, to be honest."

Krack's comments underline the delicate balancing act Aston Martin is managing. The team wants to maximise the impact of its Hungary package, but one significant accident or unexpected failure could quickly turn a promising upgrade debut into a logistical headache.

Backup plans ready if the gamble backfires

To avoid the entire project being compromised by missing components, Aston Martin has prepared contingency plans that would allow it to adapt if every planned piece is not available immediately.

The Hungarian upgrade represents the first phase of a broader recovery plan, with further improvements expected after the summer break at the Dutch Grand Prix, alongside Honda's only planned 2026 power unit upgrade.

Krack explained that flexibility has become essential given the tight deadlines.

"You always have to put scenarios in place or if you have this [part] but not this [part]," he added. "You cannot make yourself dependent on one part missing and then you cannot do it.

"So there are plans in place. It is like: if we don't have that, can we run this?

"Again, you will not have the full back-up for everything. But I think everybody has done a good job in trying to put mitigations in place, but also have plan Bs for if one or two components can't make it."

For Aston Martin, the stakes could hardly be higher. The Hungary upgrade is not simply another development step – it is a major opportunity to change the trajectory of a difficult campaign.

But before the team can find out whether its bold gamble has paid off, it must first survive the pressure test at Spa with a car that may have performance potential, but not yet the luxury of abundant spare parts.
