Koenigsegg recalls seven US CC850 hypercars over parking brake software fault

Koenigsegg is recalling all seven CC850 hypercars delivered in the United States to correct a software fault that can stop the electronic parking brake engaging, the US National Highway Traffic Safety Administration says. The recall covers cars built between September 28, 2025 and August 2, 2026.

The fault came to light after Koenigsegg received a report of a CC850 rolling away in the US on October 12, according to the recall notice. The driver had left the vehicle with the engine running and reverse gear engaged, and the car began to move.

What Koenigsegg found in testing

A week of internal testing traced the problem to a specific set of conditions: the parking brake will not engage while the transmission is in Reverse and the engine is running. In that state, the only way to apply the brake is to hold the button down continuously.

The notice does not say whether the roll-away caused any damage. NHTSA notes the condition falls outside the scope of its static parking brake tests, which suggests Koenigsegg issued the recall on its own initiative rather than because the CC850 breaches a Federal Motor Vehicle Safety Standard. That distinction matters for owners: this is a defect Koenigsegg chose to address, not a regulatory failure forced on it.

The remedy and how owners get it

All seven affected cars will receive a free over-the-air software update to resolve the issue. Owners who would rather not take the OTA update can bring their vehicle to an authorised Koenigsegg dealership and have the work carried out on site at no cost.

The sources do not state when owners will be notified or how long the update itself takes to install, so neither has been announced. What is clear is that no hardware change is involved: the entire fix is delivered in software.

The recall notice covers the seven cars delivered in the United States. Whether CC850s outside the US are affected has not been announced.

A very small fleet with a very unusual gearbox

Seven cars is a tiny recall by any measure, but the CC850 is a tiny-volume machine, so the campaign touches a meaningful share of the examples in customer hands in America. The car is priced at $3.6 million.

The CC850 is set apart from other Koenigsegg models by its nine-speed Lightspeed transmission, a part-manual, part-automatic unit with three shafts and seven clutches. It can be driven through a traditional clutch pedal and gated manual shift, or left to behave like a conventional automatic.

Ferrari has since introduced a manual transmission for the 12Cilindri built on a similar philosophy, though that version works as an add-on to an existing dual-clutch transmission. The comparison is useful context for buyers: Koenigsegg's layout is the more radical interpretation of a manual-automatic hybrid, and it is the sort of low-volume engineering that makes a software-driven parking brake fault worth fixing quickly rather than quietly.

A black Subaru WRX prototype with an unusual longtail rear end has been spotted testing at the Nürburgring, according to spy photographs published by Carscoops. The car's front and sides look identical to a standard WRX, but new panels extend outward from the rear quarters and a lip spoiler sits in line with them, giving it a silhouette unlike any current WRX variant.

What is different about this prototype

The modifications are concentrated at the back. New body panels have been attached to the rear quarters and now extend outward, sitting roughly in line with the taillights. A new lip spoiler aligns with these panels, creating a longtail effect. A small piece of camouflage is also visible on a unique rear diffuser.

From the front, the car is unremarkable: same grille, bumper, air intakes and large hood scoop as any other WRX. That is a stark contrast to the large fixed rear wings normally fitted to high-performance WRX models and any potential future STI.

Why it may not be an STI

The prototype lacks the enlarged air intakes and bigger brakes that would be expected on a high-performance STI model. It does not even appear to have the same beefy Brembo brake calipers as the regular WRX, so it seems unlikely to have any additional power under the hood.

Subaru has not announced what engine or power output the prototype uses, and the spy photographs offer no clue beyond the standard WRX hardware. The current-generation WRX has been on sale for five years, and Subaru has introduced numerous special, limited-edition versions in markets including Japan and the U.S., yet it still has not launched a proper STI model.

Other possibilities

The longtail rear could be a precursor to another special edition WRX with a distinctive rear end, an optional extra for the standard model, or simply an aerodynamic efficiency study. Carscoops notes that the design is vastly different from the large fixed rear wings expected of new WRX models and any future STI.

The spy images emerged just a week after Subaru announced it is bringing back a manual transmission option to the standard WRX in Japan. That gearbox is unrelated to the TY75 six-speed used in the U.S. model and is instead the same TY85 unit as the previous-generation WRX STI. Subaru is clearly investing time and resources in the current WRX, but the prototype does not confirm a new STI.

What it means for buyers

For anyone waiting on a new STI, this prototype is not proof one is coming. The rear-end work points to aerodynamics or packaging rather than the bigger brakes and intakes that would signal a power upgrade. The smarter read is that Subaru is still developing the current WRX, and a new range-topper would need more than a longtail to justify the badge.
