Get ready to witness a game-changer in the automotive world! The Smart #6, a groundbreaking 4.9-meter plug-in hybrid liftback, is braving the harsh Chinese winter in a series of rigorous tests. But here's where it gets intriguing: this isn't just any car—it's the largest model to emerge from the Geely-Mercedes-Benz joint venture, and it's poised to shake up the market with its innovative PHEV technology. And this is the part most people miss: it seamlessly blends German engineering precision with cutting-edge Chinese manufacturing, creating a vehicle that’s both globally inspired and locally rooted.
Unveiled in December 2025 during its homologation process by China’s Ministry of Industry and Information Technology, the Smart #6 has been generating buzz ever since. Spotted on the roads in January 2026 during initial tests, it’s now tackling extreme winter conditions, as confirmed by Smart officials on February 9. The official images showcase the vehicle against a snowy backdrop, hinting at its ability to perform in some of the world’s harshest climates. But here’s the controversial part: could this be the car that finally bridges the gap between European luxury and Chinese innovation?
While specific test details remain under wraps, it’s widely speculated that the trials are taking place in Heilongjiang province, known for its bone-chilling temperatures dipping below -35°C. This isn’t Geely’s first rodeo in the cold—they’ve previously tested models like the EX5 EM-i here, ensuring their vehicles can handle anything Mother Nature throws at them. The Smart #6, draped in thick camouflage, still reveals glimpses of its sleek design, including a roof-mounted LiDAR sensor, an interactive light panel between the headlights, and retractable door handles—features that align with its previously teased official images.
Measuring 4,906 mm in length, the Smart #6 is a mid-to-large liftback that nearly doubles the size of the iconic Smart Fortwo. Its exterior, crafted by Mercedes-Benz’s design studio, stays true to the Smart EV family’s aesthetic. Under the hood, it packs a punch with the EHD plug-in hybrid system, derived from Geely’s AI Super Hybrid 2.0. This powerhouse combines a 1.5T engine and electric motor, delivering a staggering 429 hp. With a pure electric range of 285 km and a combined range of 1,810 km, it’s as efficient as it is powerful—consuming just 3.9 liters per 100 km with a drained battery.
But here’s the question we can’t stop thinking about: Will the Smart #6 redefine what a hybrid vehicle can be, or is it just another entry in an already crowded market? Let us know your thoughts in the comments below. One thing’s for sure—this car is worth keeping an eye on as it gears up for its market debut. Stay tuned for more updates on this exciting development in the EV space!
