If you're shopping for the best small electric car right now, you've got more genuinely good options than ever before. This segment is where the EV revolution makes the most sense for everyday drivers: affordable, practical, and efficient. I spent a week with each of the top contenders — the MG4, BYD Dolphin, and Renault Zoe — driving my usual routes in and around Manchester to see which one truly earns the title of best small electric car. Here's what I found.
Why the Small EV Segment Is Better Than Ever
Two years ago, buying a small electric car meant compromising on range, interior quality, or both. The choices were limited: a cramped Zoe, an overpriced Honda e, or a Mini Electric with just 110 miles of real-world range. Now, thanks to competition from Chinese automakers and older models receiving major updates, the small EV class has matured. You can get a car with over 250 miles of real-world range, fast charging, and a cabin that doesn't feel like an economy-class seat — all for under £30,000. That shift makes the search for the best small electric car genuinely exciting.
Top Contenders: MG4 vs BYD Dolphin vs Renault Zoe
I've driven all three extensively. Here's how they compare on the specs that matter most for a small electric car.
MG4 (64 kWh, Long Range)
| Spec | Value |
|------|-------|
| Power | 203 hp (150 kW) |
| WLTP range | 281 miles (452 km) |
| Real-world range (mixed, 10°C) | 245 miles (394 km) |
| 10–80% fast charge | 35 minutes (max 135 kW) |
| Price (UK, after grant) | £26,995 |
The MG4 is the current value king. Rear-wheel drive, decent driving dynamics, and a surprisingly spacious rear seat for a car this size. The infotainment is average — not laggy, but not snappy either. The real letdown is the interior trim: hard plastics everywhere. If you care about a premium feel, look elsewhere.
BYD Dolphin (60.5 kWh, Comfort)
| Spec | Value |
|------|-------|
| Power | 201 hp (150 kW) |
| WLTP range | 265 miles (427 km) |
| Real-world range (mixed, 10°C) | 225 miles (362 km) |
| 10–80% fast charge | 35 minutes (max 88 kW) |
| Price (UK, after grant) | £25,495 |
The Dolphin is the most refined of the three. BYD's Blade Battery technology gives confidence in longevity, and the cabin feels a class above the MG4 with soft-touch materials and a clever rotating touchscreen. Downsides: the rear seat feels more cramped than the MG4, and the charging speed is noticeably slower — it peaks at 88 kW, which means longer stops on road trips.
Renault Zoe (R135, 52 kWh)
| Spec | Value |
|------|-------|
| Power | 108 hp (80 kW) |
| WLTP range | 245 miles (394 km) |
| Real-world range (mixed, 10°C) | 195 miles (314 km) |
| 10–80% fast charge | ~60 minutes (max 50 kW) |
| Price (UK, after grant) | £24,495 |
The Zoe is the veteran. It's been around since 2013 and it shows. The interior feels dated, the driving range is weakest in the real world, and DC charging is painfully slow. On the plus side, it's still cheap, small, and easy to park. But if you're looking for the best small electric car in 2025, the Zoe is hard to recommend unless you never drive more than 50 miles a day.
Real-World Range and Charging: Numbers That Matter
Lab numbers don't mean much when you're sitting in traffic at 3°C with the heater on. I drove each car over the same 100-mile loop: a mix of city, A-roads, and motorway. The MG4 returned 3.8 miles/kWh, which translates to 245 miles on a full battery. The Dolphin managed 3.5 miles/kWh (225 miles), and the Zoe struggled to 3.3 miles/kWh (195 miles). On a 150 kW charger, the MG4 took 35 minutes from 10% to 80%; the Dolphin needed 40 minutes because its charging curve drops earlier; the Zoe took 55 minutes. For a small electric car, charging speed matters more than peak power — and the MG4 wins this battle.
Which Small Electric Car Should You Buy?
After all the driving and data collection, the best small electric car for most people is the MG4 Long Range. It offers the best balance of range, charging speed, driving dynamics, and price. The BYD Dolphin comes a close second if you prioritise interior quality over ultimate range. The Renault Zoe is a distant third — only consider it if you have a tight budget and mostly do short city trips.
Who Should Buy the MG4
- You do occasional long motorway trips (>150 miles)
- You want the best value per mile of range
- You don't mind a slightly austere interior
Who Should Skip the MG4
- You want a premium cabin and soft-touch surfaces
- You need the smallest possible footprint for tight parking
Who Should Buy the Dolphin
- You spend a lot of time in your car and want a nice interior
- You rarely drive more than 200 miles in a day
- You value brand reputation for battery tech
Who Should Skip the Dolphin
- You regularly take long road trips where charge time matters
- You regularly carry three adults in the back seat
Final Verdict: The Best Small Electric Car in 2025
The MG4 Long Range is the winner. It's not perfect — the interior feels budget, and the MG brand doesn't have the same premium cachet as Renault. But when you stack up range, charging, space, and price, it delivers the most complete package. The best small electric car isn't about a single standout feature: it's about having no deal-breaking weaknesses. And the MG4 has the fewest.
Disclosure: The MG4 was a 7-day press loan from MG UK. The BYD Dolphin was a rental from Hertz. The Renault Zoe was my own vehicle, which I've owned for two years and 18,000 miles.
