The smart #3 is the second all-electric model introduced under the comprehensive joint venture between Mercedes-Benz and Geely Auto. As a compact EV coupe SUV, the smart #3 carries forward the brand's signature flair for style and individuality, while broadening its global reach with a sportier coupe silhouette. This model not only marks smart's successful transition from a traditional city-car maker into a premium all-electric brand, but also underpins its strategy to capture the youthful, high-performance segment across China and Europe.

Positioned as a compact all-electric coupe SUV, the smart #3 measures 4,400 mm long, 1,844 mm wide, and 1,556 mm tall, with a 2,785 mm wheelbase. Its headline attributes centre on "compact coupe SUV" styling and "high-performance intelligent electric mobility". Key selling points include the "sensuous and sharp" design penned by the Mercedes-Benz Global Design team, class-leading 0–100 km/h acceleration (clocking 3.6 seconds on performance variants), and an immersive digital cabin powered by the Qualcomm Snapdragon 8155 chipset. The vehicle strikes a balance between dynamic styling and practical cabin space to cater to urban drivers seeking a high-performance EV.
Debut and Launch (2023): In 2023, the smart #3 made its global debut at Auto Shanghai. As the brand's second series-production EV following the smart #1, it introduced a fresh coupe SUV profile and entered the high-end electric performance space with a dedicated BRABUS edition.
Global Expansion (2024 to Present): The smart #3 was launched concurrently in China and Europe, offering bespoke personalisation options across various markets, including BRABUS alloy wheels and interior styling packs. Through 2025 and 2026, smart has continuously refined its connected car ecosystem, broadening driver assistance coverage and elevating the user experience via over-the-air (OTA) updates.
Brand Evolution (2026 Status): As of 2026, the smart brand boasts a complete product line-up comprising the #1, #3, and the subsequent #5. Within the range, the smart #3 is styled with the persona of a "cheetah", focusing on agility and outright speed to provide a clear distinction from the brand's more conventional SUV offerings.
The smart #3 has demonstrated strong brand appeal globally. In China, it has drawn lifestyle-oriented young buyers looking for build quality and engaging vehicle dynamics; in Europe, backed by Mercedes-Benz design credentials and Geely's efficient EV platform, it has become a mainstream contender in the joint-venture EV space. Meanwhile, the flagship BRABUS variant has performed impressively in the premium segment, establishing smart's standing in the high-performance EV market.
EV Platform and Powertrain: Built on Geely's Sustainable Experience Architecture (SEA), the smart #3 is available in rear-wheel drive (RWD) and dual-motor all-wheel drive (AWD) configurations. The AWD variant delivers up to 315 kW (428 PS) and 543 Nm of torque, offering rapid acceleration courtesy of dedicated performance tuning.
Intelligent Cockpit: Powered by a high-performance infotainment chipset, the system features a 3D interface and a highly customisable voice command suite. Following 2026 software updates, the model line-up now features an expanded range of Advanced Driver Assistance Systems (ADAS) functions.
Chassis and Dynamics: Tuned by Mercedes-Benz ride and handling engineers, the smart #3 benefits from a low centre of gravity and sharp steering calibration for balanced handling stability. Depending on the variant, an adaptive electromagnetic damping setup provides a broad adjustment spectrum between Sport and Comfort driving modes.
Safety and Build Standards: Engineered to meet five-star crash safety ratings across multiple global markets, the smart #3 incorporates an advanced liquid-cooled thermal management system for the high-voltage battery, ensuring operating stability during repeated hard acceleration and long-distance highway cruising.
As smart deepens its global footprint, the smart #3 will continue to sharpen its competitive edge in connectivity and performance. The brand's forward strategy focuses on continuous OTA software updates to deliver smarter ADAS capabilities and richer cabin interaction features. Furthermore, smart is exploring bespoke customisation services and collaborations with top-tier tuning partners, unlocking greater brand equity and ensuring the smart #3 maintains its distinct appeal in an increasingly competitive compact EV segment.
