The Smart #6 EHD (stylised in all lowercase) is an upcoming plug-in hybrid mid-size liftback sedan developed and to be produced by Smart Automobile, a joint venture between Mercedes-Benz Group and Geely Holding.
Overview
The #6 EHD was officially unveiled on 5 December 2025. It is Smart’s largest model to date and is also the brand’s first sedan. The #6 also uses Geely’s NordThor Hybrid 2.0 plug-in hybrid system.[1] Rumors of the Smart brand making a sedan began spreading in February 2025.[2] This was confirmed in November 2025 when the first spyshots of the #6 surfaced on the internet.[3] It is expected to rival the Tesla Model 3 and the seventh-generation BMW 3 Series plug-in hybrid.[4]
The length of the #6 EHD is comparable to the short-wheelbase version of the second-generation BMW 7 Series. It is also as long as two first-generation ForTwos.[5] Autoblog has described the design of the #6 as reminiscent of the Xiaomi SU7 without the “McLaren-style front fascia” of the SU7.[6]
Design and features
A continuous light bar and small air intakes are present on the front of the #6. Multi-spoke rims and hidden door handles are present on the sides. The rear exhibits a wide stance. As with the front, a continuous light bar is also used at the back, this time using a more concave design. An optional rear wing is also present, and so is a LiDAR system. Multiple different headlight and taillight designs are expected to be offered, as are different brake calipers. 19 and 20-inch wheels will be offered, with tire sizes for both wheels being 255/45 and 255/40 respectively.[7]
Powertrain
The #6 uses Geely’s aforementioned NordThor Hybrid 2.0 system, shared with models such as the Smart #5 and Geely Galaxy M9. It uses a 1.5 liter turbocharged inline 4 producing 161 horsepower and an electric motor producing 268 horsepower. The transmission is a 3-speed dedicated hybrid transmission. It has a pure electric range of 177 miles (285 km) and a combined range of 1,125 miles (1,811 km) and will be offered with lithium iron phosphate batteries produced by CATL or SVOLT.[1][4]
