Despite having announced the completion of the first Valkyrie hypercar, Aston Martin may be delaying deliveries of the car because of electronics issues.

Bloomberg cites internal sources who wish to remain anonymous and said that the challenges of getting certain systems to work have delayed initial deliveries of the model. Aston Martin then confirmed to the outlet that, although the first model was completed early in November, it has not yet been handed over to its new owner.

Aston Martin downplayed the delay, though.

“The first customer car has completed its shakedown, with documentation now being prepared for delivery in the next few days,” it told the outlet, adding that the first Valkyrie will be shipped “without any compromises.” It further wrote that production was continuing “at pace.”

The spokesperson wouldn’t comment on any electronic issues but went on to say that Aston Martin expects double-digit Valkyrie deliveries before the year ends in a few weeks. To be sure, the hypercar is a complicated beast.

“The Aston Martin Valkyrie program has tested everyone who has worked on it to the limit but the commitment to the dream has produced a truly incredible car, an F1 car for the road,” said Aston Martin CEO Tobias Moers in November.

The company expects to build just 150 examples of the Valkyrie coupe (with more convertibles to follow), all of which have already sold. The cars are being built in a special production area reserved especially for the Valkyrie program and each one takes 2,000 hours of labor to complete, according to the automaker.

Powered by a hybrid V12 powertrain, Valkyrie drivers will have access to 1,139 hp (1,155 PS/850 kW). The result of a collaboration between Aston Martin and Red Bull Racing’s chief technical officer Adrian Newey, the car proudly features technology derived from Formula 1 racing.
