Vehicle Overview
The Smart #3, introduced in 2023, is the second all-electric model from the revitalized Smart brand — a joint venture between Mercedes-Benz and Geely.
While the smaller Smart #1 focuses on urban practicality, the #3 brings a sleeker, sportier, coupe-inspired crossover design, targeting drivers who want more space, performance, and sophistication in an electric SUV format.
Built on Geely’s SEA (Sustainable Experience Architecture) — also used by the Volvo EX30 — the #3 combines Mercedes-Benz design with Geely’s advanced EV engineering, resulting in a stylish and capable compact electric crossover.
With up to 455 km (283 miles) of WLTP range, ultra-fast charging, and a powerful Brabus performance variant, the 2025 Smart #3 competes with the Tesla Model Y, Volkswagen ID.5, and Hyundai Ioniq 5 as a dynamic yet accessible premium EV.
