12. Which One Should You Buy? — MG4 vs BYD Dolphin
Choosing between the MG4 vs BYD Dolphin ultimately comes down to how and where you drive most often — and what kind of ownership experience matters most to you. Below is a practical recommendation matrix to help you decide without guesswork.
🚗 Best Choice for City Driving
🏆 Winner: BYD Dolphin
If your daily routine centers around urban traffic, school runs, errands, and short commutes:
- Efficiency wins: The Dolphin’s Blade Battery (LFP) is optimized for stop/start city driving, translating into lower energy use and less frequent public charging stops.

🛣️ Best Choice for Longer Trips
🏆 Winner: MG4
For frequent highway driving, weekend getaways, and longer-distance travel:
- Range flexibility: With NMC battery options and stronger overall highway endurance, the MG4 can maintain pace and range more effectively.
- Charging performance: Slightly stronger peak DC charging means shorter breaks on longer routes.
- Handling confidence: A more planted feel at higher speeds enhances driver comfort and reduced fatigue.
The Dolphin can still handle highway miles — but for sustained high-speed efficiency and driver confidence, the MG4 has the edge.
💰 Best Value Overall
🏆 Winner: BYD Dolphin (for most budget-focused buyers)
If your priority is maximum value per euro spent, especially at purchase and early ownership:

- Generous standard features mean fewer costly optional extras.
- Lower energy consumption adds up meaningfully over repeated urban cycles.

Frequently Asked Questions — MG4 vs BYD Dolphin
Is MG4 better than BYD Dolphin?
There’s no universal “better” — it depends on your priorities. The MG4 tends to feel more engaging to drive, offers a wider range of battery options, and performs strongly on highways. In contrast, the BYD Dolphin excels in urban efficiency, battery durability, and value for money in everyday use. So if you want dynamic performance and flexible ownership, MG4 may suit you better — but for most city-centric drivers focused on low running costs, the Dolphin often feels like the smarter choice.
Which EV has better battery durability?
When looking at long-term battery health, the BYD Dolphin generally holds the edge thanks to its Blade Battery (LFP) technology. LFP chemistry is known for slower degradation and better thermal stability compared with NMC batteries — especially under regular charging habits. While certain MG4 trims also use LFP cells, the Dolphin’s standardized Blade Battery gives it an overall advantage in expected long-term durability and lower capacity loss over time.
MG4 vs BYD Dolphin for city driving
For urban environments, the BYD Dolphin is often the preferred budget EV. Its energy consumption tends to be lower in stop-and-go traffic, and the comfort-focused setup makes daily commuting relaxed and efficient. The MG4 is capable in cities as well, but its slightly firmer ride and sportier handling really reveal their strengths on faster roads. So for primarily city driving — especially short commutes and frequent charging cycles — the Dolphin generally delivers a smoother, more cost-effective experience.
Which is cheaper to own long-term?
Ownership costs include energy consumption, maintenance, insurance, and resale value — not just the purchase price. On average:
- Energy Costs: The BYD Dolphin tends to be slightly more economical thanks to efficient LFP battery performance in everyday use.
- Maintenance & Servicing: The MG4 may feel more predictable where dealer networks are strong; servicing costs remain competitive for both models.
- Resale Value & Insurance: Early signals suggest MG4 holds appeal in established used markets, while Dolphin’s long-term value is growing with its reputation.
Overall, the Dolphin often edges ahead in total low running costs, especially for urban owners focused on efficiency. But in regions with strong MG dealer support, the MG4’s predictability and resale positioning can balance the equation.
