The Koenigsegg Gemera, a four-seat hypercar often called the most powerful family car due to its 2,300 hp powertrain, has successfully passed all European Union safety, emissions, and compliance tests. The Swedish manufacturer confirmed that Gemera's in-house developed high-voltage battery system not only meets the current ECE R100.3 standards but also complies with the upcoming and more stringent 2027 R100.5 Thermal Propagation Test.
In what Koenigsegg calls a breakthrough in EV safety engineering, the brand's patent-pending battery technology successfully contained a forced thermal runaway event to a single cell during torture testing, preventing the spread of heat or fire to the rest of the pack. This performance goes beyond current global benchmarks and demonstrates how far the company's proprietary Battery Management System (BMS) and thermal isolation design have advanced.

A video released by Koenigsegg further highlights the rugged durability of the system. In the so-called "Grill test," the Gemera's battery pack endured over two minutes engulfed in direct flames, yet maintained internal temperature stability, an impressive feat that the brand highlights as the hypercar's safety-first design approach.
With its EU certification now complete, the focus shifts to the United States, where Koenigsegg is pushing to finalize homologation with the National Highway Traffic Safety Administration (NHTSA) and Environmental Protection Agency (EPA) ahead of a projected 2025 delivery timeline.

The American approval process, however, presents unique challenges. Regulations currently require physical side mirrors rather than digital camera pods, a feature that plays a key role in the Gemera's ultra-sleek, aerodynamic silhouette. Additionally, US-specific airbag calibrations for unbelted passengers must be re-engineered, adding another layer of complexity to the approval process.
Despite these regulatory hurdles, Koenigsegg says US certification is "well on its way" and expected to conclude soon. The brand's persistence in adapting one of the most complex hybrid hypercars for global markets reflects its commitment to bringing cutting-edge innovation to customers worldwide.
The Koenigsegg Gemera employs a 5.0-litre twin-turbo V8 engine that produces 1,500 hp of power and 1,500 Nm of peak torque. This, combined with the 800 hp of power from the brand's in-house "Dark Matter E-motor" gives the car an output of 2300 hp, earning it the crown of being the most powerful four-seat car. The power is transferred to the 4-wheel drive system using a 9-speed multi-clutch gearbox.
