Overview
Firefly is a battery-electric vehicle sub-brand created by Chinese electric-car manufacturer Nio. It was introduced publicly at Nio Day 2024 on 21 December 2024, when the brand's first vehicle was revealed and pre-orders opened. The debut model, also called Firefly or Firefly EV, is a small five-door hatchback positioned below Nio's larger premium vehicles and intended to compete in dense urban markets, particularly in Europe. It is the first and, in the reference material, the only vehicle produced under the Firefly name. The Firefly hatchback is designed around compact exterior dimensions and high everyday practicality. It measures 4,003 millimetres long, 1,781 millimetres wide and has a 2,615-millimetre wheelbase. Its relatively short overhangs and 4.7-metre turning radius are intended to make it suitable for narrow streets and constrained parking environments. The exterior uses a distinctive visual language built around three-circle lighting clusters and pill-shaped black accents. These motifs appear on the front and rear lighting, as well as on numerous interior components. The vehicle has a contrasting black roof, mirrors and pillars, with a body-colour strip extending across the roofline. Six exterior colours and several wheel designs are offered, with an optional lighting package. The interior emphasizes storage, flexible access and technology. It includes a 6-inch driver display, a 13.2-inch central infotainment screen, a dedicated Firefly interface, the Lumo voice assistant, ambient lighting and a wireless charging pad. Nio describes 27 storage locations, including a 92-litre front trunk, under-seat compartments and a rear cargo area that can expand substantially when the rear seats are folded. The disconnected centre console is intended to help occupants move between the passenger and driver sides when the vehicle is parked in a tight space. Interior specifications include multiple upholstery and trim choices, available front-seat ventilation and massage functions, a panoramic roof in selected markets, a 14-speaker surround-sound system and magnetic accessory mounting points. The vehicle uses a single rear-mounted electric motor manufactured by Nio's XPT unit. The motor produces 105 kW and 200 newton-metres of torque. A 42.1 kWh lithium-iron-phosphate battery supplied by Sunwoda provides a stated CLTC range of 420 kilometres. The battery is designed to be exchangeable, and the car supports DC charging at up to 100 kW. Claimed acceleration from zero to 100 km/h is 8.2 seconds, with a 150 km/h top speed. The chassis uses a high proportion of high-strength steel and a five-arm independent rear suspension co-developed with Multimatic. European-market versions are expected to receive revised steering and suspension tuning. Firefly sales began in China on 29 April 2025, after the vehicle's formal launch on 19 April. Nio announced plans to expand the brand into additional markets across Europe, Asia, Latin America and other regions. Initial international distribution was expected to combine Nio's direct-sales footprint with third-party dealers. The brand's European timing was affected by European Union tariffs on Chinese battery-electric vehicles, while right-hand-drive production was expected to begin later in 2025. The Firefly battery-swapping strategy also evolved: the brand initially contemplated a separate compact station network, but Nio later said Firefly vehicles would use its fifth-generation swap stations, expected to become operational from early 2026. Firefly therefore represents both a smaller vehicle format for Nio and a test of whether the company's battery-service ecosystem can be extended to a broader, more price-sensitive segment.
History
Firefly was established by Nio as a separate electric-vehicle marque for compact cars. The brand was first presented on 21 December 2024 during Nio Day 2024. Its debut vehicle, a small battery-electric hatchback sharing the Firefly name, was shown as the foundation of the new marque, and Nio opened pre-orders at the event. The launch positioned Firefly as a smaller and potentially more accessible complement to Nio's established premium electric vehicles and to the company's other vehicle businesses. The first public reveal was followed by further development disclosures. On 10 January 2025, images of a test vehicle operating in cold weather were released, including views that provided additional information about the cabin. Some technical details also became available through Chinese Ministry of Industry and Information Technology regulatory filings. These disclosures established the vehicle's compact dimensions, single-motor rear-wheel-drive layout, swappable battery architecture and intended urban orientation. The Firefly EV was formally launched on 19 April 2025, shortly before Auto Shanghai 2025. Deliveries in China began on 29 April. The car uses a 105 kW rear electric motor, a 42.1 kWh lithium-iron-phosphate battery and a claimed CLTC range of 420 kilometres. Its battery can be exchanged as well as recharged, reflecting Nio's broader battery-as-a-service model. The vehicle's small footprint, unusually flexible storage and high level of cabin equipment were designed to give the brand a distinct proposition in the compact hatchback segment. Firefly's design was led by Kris Tomasson, Nio's design vice president. The exterior and interior use repeated three-circle and pill-shaped forms, notably in the headlamps, taillamps, door hardware, mirror elements, speaker grilles and other cabin details. The body combines a contrasting black upper section with a body-colour roofline element. Beneath the styling, the chassis uses 83.4 percent high-strength steel and a five-arm multilink rear suspension developed with Multimatic. The packaging includes a front trunk, rear cargo space, under-seat storage and a centre-console arrangement intended to ease access in narrow parking spaces. International expansion was a central part of Firefly's original strategy. Nio expected the vehicle to reach European markets during 2025, but additional European Union tariffs on Chinese battery-electric vehicles, introduced in October 2024, contributed to a delay. Nio subsequently outlined plans to distribute Firefly in countries where it already had a direct presence, including Germany, Norway, Sweden, Denmark, the Netherlands and the United Arab Emirates, while also using dealer partners in markets such as Belgium, Luxembourg, Austria, Hungary, Portugal, the Czech Republic, Romania and Norway. Planned or announced markets also included Macau, Singapore, Costa Rica, Uruguay and Colombia, with Australia, New Zealand and the United Kingdom expected later. The battery-swapping infrastructure plan changed during the brand's launch period. Firefly vehicles were initially expected to use smaller, container-sized stations separate from Nio's existing network. Such stations were intended to reduce shipping and installation requirements and fit into locations unsuitable for larger facilities. In March 2025, Nio announced a partnership with CATL concerning a broader battery-swapping standard for future Firefly models, while the first Firefly continued with its own Nio-Firefly battery format. By the April vehicle launch, however, Nio had stated that Firefly vehicles would use Nio's fifth-generation swap stations, which were expected to begin operation in early 2026. The Firefly EV achieved a five-star rating in 2024 C-NCAP testing and includes nine airbags and advanced driver-assistance functions. Its assistance system uses a Horizon Robotics Journey 5 processor and supports supervised functions on highways and other limited-access roads, as well as automated parking. Early reported Chinese sales were 231 vehicles in April and 3,680 in May 2025. These figures represent the early phase of the brand's commercial rollout rather than a mature global sales base.

Controversies
2026
NIO recalls 686 Firefly EVs over steering sensor defect risk
NIO Auto Technology (Anhui) Co., Ltd. filed a recall plan with China's State Administration for Market Regulation defect product recall technical center to recall 686 Firefly 2026-model 42kWh battery electric vehicles produced between March 20, 2026 and April 2, 2026 (recall No. S2026M0114V). Due to a manufacturing process fluctuation, the steering column torque sensor harness may interfere with the sensor rotor, which in extreme cases can cause abnormal sensor signals, illuminate the electronic steering system fault light, and lead to loss of steering assist. Regulators have received 7 related complaints, with no reports of accidents or injuries. The company will inspect the harness and rotor for interference and replace the harness free of charge where needed, and will correct the harness installation process in production; the recall implementation period runs until December 18, 2026.
