What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Shared watch-outs for both cars
Owners of every car here flag infotainment & software. Worth checking on a test drive whichever you choose.
Leapmotor B10
67.1kWh Design
Owners love
- Owners rate it as strong value, with a long standard kit list including a 360-degree camera, ventilated seats and a panoramic roof.
- The cabin is roomy and the seats comfortable, in a car that is not oversized.
- It drives smoothly with good pull-away performance, and owners report good efficiency.
Watch out for
- Almost everything is on the touchscreen, with few physical buttons.
- There is no rear wiper, no front parking sensors and no rear interior lights, and floor mats are extra.
- Emergency lane keeping comes back on every journey, the indicators don't self-cancel and adaptive cruise is basic.
Owner tips
- Set up the shortcut button to turn off lane-keeping and other driver aids.
- Turn off fast boot to avoid a small daily battery drain.
Smart #5
Pro
Owners love
- Exceptional interior space with comfortable rear legroom, reclining seats, and 630 litres of boot space
- Outstanding acceleration (3.8 seconds 0-62mph) and impressive 800V fast charging (10-80% in 18 minutes at optimal conditions)
- Advanced infotainment with three screens, superb conversational voice control, and premium materials (Alcantara, vegan leather)
Watch out for
- High energy consumption significantly impacts real-world range compared to competitors despite 335-mile WLTP rating
- Design is polarizing and divisive; frequently compared unfavorably to the Nissan Cube with questionable styling details
- 335-mile WLTP range underwhelming for a 100kWh battery and not class-leading compared to rivals
Owner tips
- Test drive the rear-wheel drive base models which offer better steering feel, more dynamic handling, and additional frunk space compared to all-wheel drive variants
- Visit dealerships in person to confirm driver's seat comfort if over 6 feet tall and test voice assistant behavior to ensure it suits your driving style

Frequently asked questions

The Smart #5 costs £8,305 more than the Leapmotor B10. For that premium it adds 200 litres more boot space, 90 kW more power and a 1.1s quicker 0-62mph time. On EVcarsguide's combined category scores, the Leapmotor B10 comes out ahead overall.
Which is cheaper to own over 5 years, the Leapmotor B10 or the Smart #5?
The Leapmotor B10 is £8,305 cheaper to buy. Running costs are almost identical - about £192 a year either way, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Leapmotor B10 comes out roughly £8,345 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Leapmotor B10 and Smart #5 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 193 miles for the Leapmotor B10 and 202 miles for the Smart #5 - effectively matched, and both well below their WLTP figures because sustained high speed is the hardest case for an EV. A rapid charge to 80% takes around 20 minutes in the Leapmotor B10 and 30 in the Smart #5, so the Leapmotor B10 loses less time at each stop.
Which is easier to park and drive in town, the Leapmotor B10 or the Smart #5?
The Leapmotor B10 is the easier car for tight UK car parks: it is 35 mm narrower than the Smart #5. In a standard 2,400 mm bay that leaves about 515 mm of total clearance for the Leapmotor B10 and about 480 mm of total clearance for the Smart #5.
Which battery will hold up better as a used buy, the Leapmotor B10 or the Smart #5?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the Leapmotor B10 and 90% for the Smart #5. That is close enough that capacity loss should not decide between them. Both use LFP-type cells, which are happy charged to 100% every day. Both batteries carry a 8-year manufacturer warranty.
