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 real-world range. Worth checking on a test drive whichever you choose.
Mercedes-Benz EQA
250
Owners love
- Owners consistently praise the build quality, quietness and comfort, with very comfortable front seats.
- Real-world range is close to or above the official figure in summer for many owners, with around 3.5 to 4.5 miles per kWh reported.
- Rapid charging holds a high rate for much of the charge, so stops are quick by the standards of its size.
Watch out for
- The car has no built-in charge scheduling, so owners rely on a smart home charger or tariff app for cheap night rates.
- Winter range drops to roughly 200 miles or less, and the range display can be inaccurate.
- The boot is small and rear legroom is tight for tall passengers because of the raised floor.
Owner tips
- Use a smart home charger or tariff app to time charging, as the car cannot.
- Use the D Auto regeneration setting for the best efficiency.
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
