These two Chinese models are aimed at the same public in search of an accessible and versatile electric car, ideal for both city driving and long journeys.
With modern designs, advanced on-board technologies and batteries offering competitive range, they are positioned as serious alternatives to European models. Which one to choose? It all depends on your criteria: the BYD Dolphin relies on its comfort and efficiency, while the MG4 impresses with its dynamism and driving pleasure.
BYD Dolphin vs MG4: which offers the best performance and the longest range?
Which engine and which power between the BYD Dolphin and the MG4?
La BYD Dolphin and the MG4 offer high-performance electric motors to suit different needs. The Dolphin Premium is powered by a 150 kW (204 hp) motor with 310 Nm of torque, enabling it to accelerate from 0 to 100 km/h in 7 seconds. In comparison, the MG4 Long Range has a 201 bhp (150 kW) motor and slightly less torque, but its XPower version reaches impressive levels with 429 bhp thanks to two motors and all-wheel drive.
These configurations show that the MG4 offers more powerful options for performance enthusiasts, while the Dolphin focuses on agile, well-balanced driving.
BYD Dolphin vs MG4: which has the best range for daily commutes and long journeys?
In terms of range, the MG4 Extended Range offers up to 323 miles (around 520 km), surpassing the 427 km WLTP of the BYD Dolphin Premium. However, in real-world conditions, the Dolphin tends to be closer to its claimed range thanks to its superior fuel efficiency. This makes it an interesting choice for urban and suburban journeys. For long-distance journeys, the MG4 remains more suitable thanks to its battery (64 kWh compared with 60 kWh) and extended range.
Recharging time and compatibility with fast-charging stations: which model is most practical?
The MG4 stands out for its compatibility with fast charging stations of up to 140 kW, allowing 10 to 80 % to be recharged in just 26 to 35 minutes, depending on the model. The BYD Dolphin Premium, on the other hand, reaches a peak charge of 88 kW, requiring around 30 minutes for a similar charge.
Although the difference is minimal in terms of time, the MG4's fast-charging capability offers added convenience for long journeys. Both models use Type 2 CCS connectors, guaranteeing compatibility with most European infrastructures.

Design and interior: which is more comfortable, the BYD Dolphin or the MG4?
What are the design choices and finishes of the two electric compacts?
The BYD Dolphin is distinguished by its bold, marine-inspired design, with flowing lines and bright colours that reflect its playful character. It is available in a number of trim levels, including Active, Boost, Comfort and Design, offering a wide range of equipment from entry-level models onwards, such as a 12.8-inch rotary screen and heated synthetic leather seats.
In contrast, the MG4 adopts a more dynamic, modern style with details such as its distinctive LED lights and a varied colour palette including Brighton Blue and Fizzy Orange. Its trims include SE, Trophy and XPower, each of which brings specific equipment such as an advanced multimedia system and alloy wheels.
BYD Dolphin vs MG4: which car offers the most interior space and boot space?
The BYD Dolphin offers generous interior space thanks to its completely flat floor and relatively long wheelbase. In the rear, passengers enjoy good legroom, while the boot has a capacity of 345 litres, extendable to 1,310 litres with the seats folded down. The MG4 is slightly more spacious, with a boot capacity of 363 litres (1,177 litres with seats folded), but its cabin is less airy due to its reduced vertical dimensions.
However, it can accommodate three adults in the rear, thanks to a design optimised to maximise cabin space. As a result, the Dolphin focuses on interior comfort for rear passengers, while the MG4 offers a slight advantage when it comes to transporting bulky objects.
Which model offers the best driving comfort and the most effective soundproofing?
The BYD Dolphin boasts innovations such as a motorised 12.8-inch swivelling screen, a first in its class, which can be used in portrait or landscape mode, depending on the driver's preference. It also incorporates modern features such as Apple CarPlay and Android Auto, as well as a dedicated mobile app for controlling certain functions remotely. However, certain aspects, such as the absence of a native route planner, limit its technological potential.
The MG4, meanwhile, is based on an advanced electric platform with rear-wheel drive or all-wheel drive on the XPower version. It offers superior driving aids (blind spot detection, lane change assist) and rapid recharging up to 140 kW, surpassing the Dolphin in practicality for long journeys. In terms of overall innovation, the MG4 seems to offer solutions better suited to European needs.
What driving assistance systems are available on each model?
The BYD Dolphin offers conventional driving aids such as lane keeping, adaptive cruise control and autonomous emergency braking. However, these systems suffer from inaccurate calibrations that can make them uncomfortable or even dangerous to use in certain situations (particularly on narrow roads). A software update is planned to correct these problems.
The MG4 offers a more comprehensive and better calibrated range of driving aids. In addition to the standard functions (autonomous braking, adaptive cruise control), it includes advanced options such as lane change assist and rear cross-traffic detection. Overall, these systems are better adapted to European infrastructures and offer a more reassuring experience for the driver.
Infotainment and connectivity: BYD Dolphin vs MG4, which offers the best digital experience?
The BYD Dolphin features an Android-based infotainment system with a 12.8-inch swivelling central screen. It includes integrated Spotify, Apple CarPlay and Android Auto as standard. However, the ergonomics of its interface have been criticised for being unintuitive. In addition, the lack of a native route planner is a notable shortcoming for complex journeys.
The MG4 offers a smoother digital experience with a modern touchscreen and a well thought-out interface. It also includes Apple CarPlay and Android Auto, but stands out for its integrated route planner and advanced features for optimising electric journeys. Overall, the system is judged to be more user-friendly and better adapted to the needs of European drivers.
