How Leapmotor Builds the B10 in Spain, From Local Battery Assembly to Chassis Parts

Stellantis and Leapmotor started series production of the Leapmotor B10 at the Zaragoza plant this month, according to the Stellantis press release. The B10 shares the plant with the Opel Corsa, Peugeot 208 and Lancia Ypsilon, which helps Stellantis fill spare capacity: the release cites the plant’s available capacity, and CEO Antonio Filosa said Stellantis’s European plants ran at around 60% utilisation in 2025, according to electrive. The battery is one of the most complex parts of any EV, and Leapmotor is handling part of it locally on the B10, with battery module assembly and chassis production set up nearby. I listed where else Chinese brands build cars in my guide to Chinese EV manufacturers producing in Europe.

Battery Modules and Chassis Parts Come From Nearby

Battery modules are assembled at a new Leapmotor plant in Mallén, which supplies the LFP Pro and ProMax versions of the B10, according to the Leapmotor International release, with backing from the Spanish government, the Aragon government and the local council. I believe Leapmotor wants to localise as much of the B10 as it can for three reasons: the EU tariff on Chinese-built EVs, the political support that comes with hiring local workers, and the cost, since some parts are cheaper to make on the spot than to ship from China.

elDiario reports 90 workers at Mallén, according to Aragon’s economy councillor, a €25 million investment and ten Aragonese companies involved in the assembly. The chassis parts come from Lieder Automotive in Borja, a joint venture between China’s Duoli Technology and the Basque supplier Fagor Ederlan, according to electrive. French supplier OPmobility has also won Leapmotor International contracts for bumpers and tailgates, made at its existing Spanish plants from 2027, though its press release doesn’t name the model.

Why I Expect the Price to Stay

Imported Leapmotors pay a 20.7% EU countervailing duty on top of the standard 10% car duty, which makes 30.7% in total, and my overview of EU tariffs on Chinese electric cars has the full rate table. Cars built in Spain pay neither, but the Stellantis release says nothing about whether that will lower B10 prices in Europe. Here’s what the B10 costs today.

Starting prices from Leapmotor’s national websites on 27 October 2026. Danish and UK prices are converted at ECB reference rates and rounded, and the trim behind each price differs by market.

Prices in the table are what Leapmotor lists today, and I don’t expect them to fall despite the savings. I’d expect building cars in Spain to cost more than building them in China, so the real saving is probably smaller than the 30.7% rate suggests. The duty is also charged on the customs value of the imported car, which is lower than the sticker price.

The clearest gain from Spanish production is jobs and work for local suppliers: Figueruelas has formalised more than 400 new hires, according to Somos Eléctricos, and the Mallén plant adds 90 workers.
