First Look

The Smart #6 is a plug-in hybrid saloon that’s ready for a fight

Watch out, BMW 3 Series and Merc C-Class, there’s a new saloon in town

Published: 09 Dec 2025

Ah, Smart. Once a maker of teeny tiny city cars, now a maker of many… bigger ones. And, it turns out, plug-in hybrid saloons. Meet the Smart #6.

Wasn’t expecting that one today. So, two things to note straight off the bat – 1) it’s the carmaker’s first ever saloon, and 2) it’s destined for the Chinese market only. So if you’re eyeing up the pictures above thinking you fancy a bit of that and you live in the UK… tough.

On we go. At 4.9m long, 1.9m wide, and 1.5m tall, it’s bigger than both the BMW 3 Series and Merc C-Class that it wants to duff up.

Underneath it gets Smart’s latest Electric Hybrid Drive (EHD) system, which pairs a 1.5-litre four cylinder petrol engine, electric motor and 41.46kWh battery pack, all mated together courtesy of a three-speed DHT transmission.

Combined power output is 429bhp, with Smart claiming a 177-mile all electric range and a 1,125-mile combined figure – at least on China’s generous CLTC test cycle. Fuel consumption officially stands at 72.4mpg, but again that’ll be lower on Europe’s WLTP standard.
