A deep dive into its production in Bratislava

Production in three stages: battery, body shell, and final assembly

Since 2002, the Cayenne has been linked to Bratislava. In the early days, only the body shells were manufactured on-site before being shipped to Leipzig, where they received their powertrains. In 2017, with the introduction of the SUV’s third generation, full production was transferred to Bratislava. With the electric Cayenne, the site reaches a new level: it now produces high-voltage batteries and handles all assembly stages — from the body shell to the finished vehicle. Production is therefore structured in three stages: the manufacturing of battery modules at the new Horná Streda plant, body shell assembly, and finally the vehicle’s final assembly. Each step showcases Porsche’s technical expertise and high quality standards.

The Smart Battery Shop: at the heart of the power

Far more than a simple component, the electric Cayenne’s battery is a central element that equally determines the SUV’s performance, range, and responsiveness. To master every parameter, Porsche made the strategic decision to develop and assemble its battery modules entirely in-house — at the Smart Battery Shop in Horná Streda. Inaugurated in 2024, this state-of-the-art 40,200 m² facility relies on a very high degree of automation, covering 98% of the production process, while also drawing on human expertise to ensure an optimal level of precision and reliability. Each battery module consists of 32 NMCA pouch cells, manufactured by LG in Poland. These are carefully prepared, stacked, laser-welded, and then integrated into their casings. It should be noted that these cells were developed by LG according to extremely strict specifications defined by Porsche, to ensure the exceptional performance of the new electric Cayenne. Six modules are then assembled to form the final battery pack, comprising a total of 192 cells and a capacity of 113 kWh. This architecture enables power output of up to 850 kW during acceleration and a regeneration capacity of up to 600 kW during braking (comparable to Formula E). The battery also features an innovative dual-plate thermal management system that handles both the cooling and heating of the cells. This technology simultaneously optimizes battery longevity, power availability, and charging speed — regardless of operating conditions.

Body shell assembly: sculpting and precision

Alongside battery production, the Cayenne takes shape in the platform hall — where its body shell, also known as the body in white, is born. This is where the chassis, the so-called ‘skateboard,’ progressively receives the side panels, roof, doors, hood, and tailgate. The forming presses exert up to 9,300 tons of force to shape each body element. The panels are then automatically inspected to verify their dimensions before being assembled with extreme precision — by welding, bonding, riveting, or bolting. Once the structure is complete, the alignment of the elements is carefully checked, both by advanced inspection systems and by the skilled hands of operators on the assembly line. The finished body shell then undergoes thorough inspections, including three-dimensional measurements and X-ray checks, to ensure the quality and integrity of the welds. Once these checks are complete, the body moves to the paint shop. There, each body shell first receives several layers of anti-corrosion protection before the customer’s chosen color is applied. Porsche also offers the exclusive and particularly demanding ‘Paint to Sample’ (PTS) option, allowing the vehicle’s color to be customized to individual wishes.

Final assembly: flexibility on a shared line

In the next step, final assembly, combustion or electric motors, running gear, and individually designed interiors are brought together. Integrated into the chassis floor, the battery directly contributes to the overall structural rigidity of the vehicle and lowers the center of gravity. It thus plays a key role in the Cayenne’s dynamic handling, which stands out for its remarkable agility and balance given its size. A strategically significant detail: the electric Cayenne is manufactured on the same line as the combustion and hybrid versions, which continue to be produced in parallel. This decision offers maximum flexibility in response to global market fluctuations, where electric power is far from dominant yet. It fits seamlessly into Porsche’s strategy, recently validated by the European Commission, which no longer targets 100% electric vehicles by 2035. In this plant, 90% of operations are automated, but the finishing touches — particularly for personalization through the Porsche Exclusive Manufaktur program — remain entrusted to skilled hands. The vehicles then go through a series of tests: rolling checks, wireless charging trials, electronic verification, and installation of the latest firmware. Every Cayenne leaves the factory ready to deliver the expected performance and quality.

With around 12,500 employees, Bratislava is Slovakia’s largest private employer — a place where automation and human expertise work hand in hand. The new Cayenne demonstrates how Porsche successfully transfers its sporting DNA to the electric era — from the battery to the finished vehicle. The production flexibility to continue manufacturing combustion, hybrid, and electric vehicles on a single line, the attention to the environment, and the high degree of automation reflect the innovation, performance, and sustainability offered by this exceptional SUV.
