BYD X-PACK electric minicar for Europe: what we know so far
BYD plans to bring the space-saving X-PACK battery and inverter architecture from its Japanese Racco kei car to a new compact EV for Europe, according to Nikkei.
The BYD Racco remains, for now, a Japan-only kei car, but its core piece of engineering is about to travel far beyond Japan. According to Nikkei, BYD has decided to use the X-PACK architecture developed for the Racco to build new compact electric vehicles for Europe and other global markets. Detailed development is set to begin soon, with production models expected within a few years. BYD has not officially announced this global project.
X-PACK is about more than a smaller battery. In the Racco, the inverter and several other power-electronics components are integrated into the battery pack itself and mounted under the floor. The manufacturer officially describes X-PACK as a new integrated EV technology designed for a car with tightly constrained dimensions. The freed-up space can go toward the cabin and the front crash-deformation zone — a particularly valuable trade for a small car.
The production Racco shows the scale of the engineering challenge. It measures 3,395 mm long and 1,475 mm wide. Range, depending on the version, reaches 210 or 320 km on the Japanese test cycle, and the starting price is 2.145 million yen, roughly $14,700.
The European side of the story needs some clarification. It has previously been reported that the EU had already decided to create an equivalent of Japan's kei-car class. More precisely, the European Commission presented its Small Affordable Cars package in December 2025, introducing a new subcategory for zero-emission vehicles no longer than 4.2 metres. The proposal allows for targeted incentives, but as of August 2026 it remains a legislative initiative rather than an automatic, unified benefit for any qualifying car.
That means BYD's future European model won't have to match the Racco's 3.4-metre Japanese footprint. A European car could be noticeably larger than the Racco while keeping X-PACK's main advantage — a compact, tightly packaged electrical system. In BYD's current lineup, that space just above the minicar segment is already covered by the Dolphin Surf, at roughly four metres long; that model is also gradually being adapted to European requirements, including a five-seat cabin.
There's an industrial logic to it too: BYD is expanding its European footprint and preparing local production in Hungary. The company has not yet said that a future X-PACK-based EV would actually be built there — that remains a scenario described by Nikkei rather than a confirmed plan. BYD's European dealer network, meanwhile, continues to grow quickly.
Until an official unveiling, the new model's name, dimensions, battery, power output, range and price are all unknown. So the key fact right now is different: BYD has decided to turn a technology born out of Japan's strict size limits into a global tool for developing compact electric cars.
