Aptera builds first solar EV on validation production line

Aptera has installed and commissioned its validation vehicle assembly line, which has been under construction at its factory since mid-November 2025. The validation assembly line serves its usual purpose: enabling engineers and technicians to refine the systems, tools, and processes that will later be used in series production. For Aptera, this phase is particularly significant, as the solar-electric vehicle features a large carbon-fibre monocoque, which requires different assembly processes than, for example, a steel body. The centrepiece of the new facility is a large-format precision assembly device developed specifically for Aptera’s Body-in-Carbon (BinC) structure.

The first vehicle has now been produced on this line, with previous models built using significantly more manual labour during prototype development. “The company’s low-volume validation assembly line represents Aptera’s transition from hand-built validation vehicles to a structured assembly line process,” Aptera states.

The line consists of 14 specialised stations, where vehicles are assembled by a team of technicians. That ‘repeatable builds, process verification, and optimisation,’ the company adds. The layouts of individual stations can still be adjusted during this phase before moving on to the planned series production lines, which will be built using insights gained from the validation process.

The first vehicles assembled on the new line are not yet intended for customers but will undergo extensive testing. That includes thermal validation, brake performance testing, and ‘destructive testing,’ such as crash tests. EPA certification for consumption and range figures is also still pending and will be carried out using vehicles from the validation line.

Aptera reports that, with ‘sustained hiring across key roles,’ its assembly and integration department has become the company’s largest functional team. The fact that more employees are working in assembly than in areas such as design, procurement, and development is seen by the company as ‘the beginning of its transition from engineering development to testing and production execution.’

“The completion of the first vehicle off our low-volume assembly line is a significant achievement for the entire company,” said Steve Fambro, Co-CEO of Aptera. “These first vehicles will be used to complete the key tests and optimisation required to sell our first vehicles to customers.” 

According to Aptera, the vehicle has received nearly 50,000 reservations, representing potential revenue of more than two billion US dollars. However, these reservations are not binding orders and can still be cancelled at any time. The company thus says it will continue to focus on ‘disciplined execution’ in order to deliver the first vehicles to customers later this year.

The Aptera solar-electric vehicle is designed to offer a range of up to 643 kilometres (400 miles) and, thanks to integrated solar cells, can travel an additional 64 kilometres per day on self-generated electricity. In ‘sunny climates,’ Aptera promises around 16,000 additional kilometres per year using solar power alone. To keep the vehicle lightweight, it is primarily constructed from a carbon-fibre moulding compound (CF-SMC).

Update 20 May 2026

Aptera Motors announced that five validation vehicles have been driven off its newly established low-volume validation assembly line. Running multiple vehicles through the line in sequence validates not only the vehicle itself, but the system required to build it consistently, the company points out.

“What we are building here is not just vehicles, but the system to build them well,” said Steve Fambro, Co-CEO of Aptera Motors. “Each cycle through the line improves precision, efficiency, and repeatability. This is how we plan to meet our customers’ expectations when they finally get their hands on their own Aptera vehicle.”
