What owners say

Shared watch-outs for both cars
Owners of every car here flag infotainment & software, real-world range. Worth checking on a test drive whichever you choose.
Hyundai IONIQ 5
Standard Range RWD
Owners love
- Exceptional driving dynamics with outstanding handling, steering precision, and engaging performance that feels like a proper driver's car despite its 2.2-ton weight
- Cutting-edge 800-volt charging architecture enables industry-leading 350kW fast charging speeds, significantly faster than most competitors
- Impressive range with larger battery options (315+ miles WLTP) and strong real-world performance in various conditions
Watch out for
- Poor efficiency for its class, achieving only 2.5-2.7 mi/kWh in real-world driving, resulting in disappointing real-world range despite manufacturer claims
- Premium £65,000 pricing lacks competitive justification given interior quality comparable to standard Ioniq 5 and efficiency below competitor standards
- Known vulnerability to theft via programmable key exploits, particularly concerning in high-risk areas, with ongoing unfixed security issues
Owner tips
- Test drive extensively and set up suspension and drive modes (Normal suspension recommended for UK roads, Sport steering, Sport+ motor settings) to match your preferences before committing
- Budget for security upgrades like Ghost immobilizer in high-theft areas; check insurance quotes early due to known theft vulnerabilities
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 Hyundai IONIQ 5 or the Smart #5?
The Smart #5 is £895 cheaper to buy. The Hyundai IONIQ 5 is cheaper to charge, roughly £160 a year versus £200 for the Smart #5, at 8,000 miles on an off-peak home tariff. Add 5 years of charging and the Smart #5 comes out roughly £695 cheaper overall. These figures cover list price and home charging only - insurance, servicing, tyres and depreciation will move the real total.
What are the Hyundai IONIQ 5 and Smart #5 like on a long motorway trip?
EVcarsguide estimates a real-world motorway range of about 228 miles for the Hyundai IONIQ 5 and 202 miles for the Smart #5 - both below their WLTP figures, because sustained high speed is the hardest case for an EV. The Hyundai IONIQ 5 goes roughly 26 miles further between charging stops. A rapid charge to 80% takes around 18 minutes in the Hyundai IONIQ 5 and 30 in the Smart #5, so the Hyundai IONIQ 5 loses less time at each stop. That makes the Hyundai IONIQ 5 the stronger long-distance car.
Which is easier to park and drive in town, the Hyundai IONIQ 5 or the Smart #5?
The Hyundai IONIQ 5 is the easier car for tight UK car parks: it is 30 mm narrower than the Smart #5. In a standard 2,400 mm bay that leaves about 510 mm of total clearance for the Hyundai IONIQ 5 and about 480 mm of total clearance for the Smart #5.
Which battery will hold up better as a used buy, the Hyundai IONIQ 5 or the Smart #5?
Over a 8-year ownership window EVcarsguide's degradation model projects roughly 89% battery health for the Hyundai IONIQ 5 and 90% for the Smart #5. That is close enough that capacity loss should not decide between them. The Smart #5's LFP-type pack tolerates daily 100% charging, while the Hyundai IONIQ 5's NMC-type pack lasts longest kept to about 80% for everyday use.
