MG ZS EV vs BYD Dolphin: Which Electric SUV Wins?

This article provides a comprehensive, data-driven comparison between the MG ZS EV and the BYD Dolphin, two prominent electric SUVs in the UK market. By examining exterior and interior design, performance, efficiency, pricing, driving experience, and customer feedback, readers will gain a clear understanding of each model’s strengths and weaknesses. This analysis is intended to assist engineers, technicians, and informed buyers in making a rational, technically sound decision when selecting their next electric SUV.

Exterior Design

The MG ZS EV boasts a contemporary, refreshed front fascia featuring a perforated grille and sophisticated LED lighting, which together create a modern SUV aesthetic. The charging port is conveniently positioned at the front, and the 17-inch alloy wheels are designed for optimal efficiency. Trophy variants include roof rails and a panoramic glass sunroof, while the rear is equipped with subtle LED lights and integrated sensors. Conversely, the BYD Dolphin is styled with its distinctive 'Ocean aesthetics' theme, incorporating sharp crease lines and a continuous LED headlight bar. Its compact proportions (4,290 mm in length) and two-tone paintwork lend it a unique, if somewhat understated, hatchback-inspired appearance. While the Dolphin is often described as clean and contemporary, it is generally considered less visually impactful than the MG, although its dynamic lighting elements add a touch of individuality.

Interior Design

The MG ZS EV’s cabin emphasises space and comfort, featuring leather-style upholstery, contrast stitching, and a clear, user-friendly dashboard. The 10.1-inch touchscreen and 7.0-inch driver display provide all essential vehicle information, and rear passengers benefit from a fold-down armrest and multiple charging points. Trophy trims further enhance the sense of spaciousness with a panoramic sunroof. However, some interior plastics may feel less premium, and the analogue dials are less sophisticated compared to fully digital alternatives. The BYD Dolphin, in contrast, offers a futuristic, cyberpunk-inspired interior with a 12.8-inch rotating touchscreen, vegan leather sports seats, and a suspended centre console. The minimalist dashboard, bold contours, and two-tone finishes create a thoroughly modern environment. Generous storage and a panoramic glass roof (Design trim) add to the sense of space, though some users find the control layout less intuitive than in the MG, with certain ergonomic compromises noted.

Engine and Performance

The MG ZS EV is powered by a single electric motor delivering 143bhp and 260lb ft of torque, resulting in a 0-62mph time of 8.5 seconds and a top speed of 87mph. The powertrain is engineered for smooth, linear acceleration, particularly suited to urban driving. While not designed for high performance, it offers ample power for daily commutes and motorway journeys. The BYD Dolphin provides a wider array of powertrains: Comfort and Design trims offer 201hp (0-62mph in 7.0 seconds), the Boost trim delivers 176hp (7.5 seconds), and the entry-level Active trim produces 95hp (12.3 seconds). All variants are front-wheel drive and employ BYD’s Blade Battery technology, renowned for its safety and efficiency. The higher-powered Dolphin trims surpass the MG ZS EV in acceleration, though the entry-level version is less powerful.

Efficiency and Charging

The MG ZS EV is available with either a 51kWh battery (198 miles WLTP range) or a 72kWh battery (273 miles WLTP range). Using CCS rapid charging (up to 50kW), a 0-80% charge can be achieved in approximately 40 minutes, while a 7kW AC charger requires around 6.5 hours for a full charge. The liquid-cooled battery ensures consistent performance during charging. The BYD Dolphin, in Comfort and Design trims, utilises a 60.4kWh battery, offering a WLTP range of up to 265 miles, with real-world figures typically between 220 and 240 miles. Efficiency is rated at 3.9–4.1 mi/kWh, with some tests reporting over 5 mi/kWh. The Dolphin supports faster rapid charging (up to 110kW DC), enabling a 10-80% charge in just 36 minutes. Lower-spec trims are fitted with smaller 44.9kWh batteries, providing a range of 193–211 miles. Additional features include an integrated heat pump and Vehicle-to-Load (V2L) capability for external power supply, enhancing practicality.

Price

In the UK, the MG ZS EV starts at £28,495 for the SE Long Range, with the Trophy Long Range priced at £30,995 and the Trophy Connect Long Range at £31,495. Pre-owned models are available from around £11,316. The BYD Dolphin range begins at £26,195 for the Active trim, with Comfort at £30,230 and Design at £31,695–£31,730. Used Dolphins are available from £15,995. Overall, the MG ZS EV provides a lower starting price for new long-range models, whereas the entry-level BYD Dolphin is more affordable but offers reduced performance and range.

Driving Experience

The MG ZS EV is engineered for comfort and quietness, excelling in city environments with low noise levels and predictable handling. The ride is generally smooth, although the soft suspension can become unsettled at higher speeds. Steering feedback is modest, and while three assistance settings are provided, none offer a particularly engaging experience. Regenerative braking is adjustable, and adaptive cruise control is standard on higher trims. The BYD Dolphin also delivers a comfortable ride, supported by a calm and efficient powertrain. Its steering is similarly lacking in engagement, and some drivers report that the lane-keeping assistance can be intrusive. The ride remains composed on smooth roads, but wind and road noise are more noticeable at motorway speeds. The unconventional gear selector design quickly becomes familiar. Both vehicles feature adaptive cruise control and are well-suited to everyday commuting, with the Dolphin’s slightly higher driving position potentially appealing to SUV enthusiasts.

Customer Reviews and Ratings

MG ZS EV owners frequently commend its reliability, build quality, and low running costs. Positive remarks highlight the smooth, quiet drive, practical range, and effective safety systems. Criticisms include the soft suspension at speed, the absence of certain features (such as an auto-dimming mirror and lumbar support), and occasional infotainment issues. The BYD Dolphin is praised for its stylish, spacious interior, comfort, and efficiency. Reviewers appreciate its practicality, range, and adaptive cruise control, particularly for longer journeys. However, the unconventional interior layout and sometimes intrusive driver assistance systems are noted as drawbacks. Both models are recognised for their affordability and suitability for urban use, with the Dolphin achieving a 5 Green Star rating from Green NCAP.

Final verdict: MG ZS EV or BYD Dolphin?

In summary, both the MG ZS EV and BYD Dolphin are compelling electric SUVs for UK buyers, each with distinct advantages. The MG ZS EV excels in affordability, practical range, and straightforward usability, making it ideal for those prioritising value and reliability. The BYD Dolphin offers superior acceleration (in higher trims), faster charging, and a more advanced interior, appealing to drivers seeking innovation and efficiency. For most users, the MG ZS EV represents the best balance of price, practicality, and comfort.
