What owners say
Aggregated from UK owner forums and communities - the things you only learn after living with the car.
Ford Mustang Mach-E
Standard Range RWD (2021-24)
Owners love
- Owners consistently praise the looks, the strong acceleration and a refined, quiet drive.
- Extended Range owners report around 290 to 315 miles in mild conditions, enough to charge only every week or two for many.
- Running costs on an off-peak home tariff are very low, and owners describe large monthly savings over a petrol car.
Watch out for
- Rapid charging slows sharply above 80%, so owners plan long trips around charging to about 80%.
- Some owners find the ride fidgety on poor roads and parts of the interior plastics cheap.
- The boot is modest for an SUV of this size, and the glass roof has no blind.
Owner tips
- Choose the Extended Range if you do long trips: owners say the extra range matters more than all-wheel drive.
- Charge to about 80% on rapid chargers on long journeys to keep stops short.
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
Which is cheaper to own over 5 years, the Ford Mustang Mach-E or the Smart #5?
The Smart #5 is £550 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 Smart #5 comes out roughly £510 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Ford Mustang Mach-E and Smart #5 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 203 miles for the Ford Mustang Mach-E 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. Both rapid-charge to 80% in a similar time, around 30-32 minutes.
Which is easier to park and drive in town, the Ford Mustang Mach-E or the Smart #5?
The two are within 10 mm on width, so neither is meaningfully easier to thread into a tight space. In a standard 2,400 mm bay that leaves about 480 mm of total clearance for the Smart #5 and about 470 mm of total clearance for the Ford Mustang Mach-E.
Which battery will hold up better as a used buy, the Ford Mustang Mach-E or the Smart #5?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 90% battery health for the Ford Mustang Mach-E 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.
