BYD Song Plus Review: PHEV vs EV, Specs, Safety, and Buying Guide

The BYD Song Plus is one of the clearest examples of how Chinese SUVs have moved from value-led alternatives to genuinely polished family vehicles.

In markets where it is sold as the Song Plus and in Europe as the Seal U, it stands out because you can choose between a plug-in hybrid DM-i version and a full-electric EV version, each aimed at a different kind of buyer.

What the Song Plus is

The Song Plus sits in the compact-to-midsize SUV space, with dimensions around 4,775–4,785 mm in length, 1,890 mm in width, and 1,660–1,670 mm in height, depending on the market and powertrain. Its wheelbase is 2,765 mm, which is the number that matters most for cabin space, because it gives the SUV the long, stable proportions that usually translate into better rear-seat room and a more planted stance on the road.

BYD has built the model around its Ocean-style design language, but the real story is under the skin: the EV uses a large LFP Blade battery, while the DM-i plug-in hybrid combines a small displacement 1.5-litre engine with an electric drive system for efficient city use and long-distance flexibility. That makes the Song Plus a practical “one-car solution” for buyers who want electric driving without the charging dependency of a full EV.

Key specs at a glance

PHEV or EV

The DM-i version is the more versatile choice if you drive long distances, live in a place with inconsistent charging, or want to reduce fuel use without fully committing to electric-only ownership. BYD describes the DM-i setup as “Super Hybrid Plug-in: Electricity and Fuel,” and its own market materials show low fuel consumption figures around 3.88–3.9 L/100 km when the battery is at a low state of charge.

The EV version is the cleaner choice if your charging access is reliable and your daily routine is predictable. Official BYD materials for the EV mention a 71.8 kWh Blade battery and a driving range of about 520 km in CLTC testing, while a separate market sheet shows a 405 km WLTC figure for another EV variant. That spread is normal because range claims depend heavily on test cycle, wheel size, trim, and market calibration.

Which version suits you

• Choose the DM-i if you want fuel backup, easier road-trip planning, and fewer charging constraints.
• Choose the EV if you want lower local emissions, simpler maintenance, and a quieter driving experience.
• Choose the DM-i if your country’s public charging network is still developing, because the petrol engine removes range anxiety in a way a full EV cannot.
• Choose the EV if you have home charging and your mileage is mostly urban or suburban.

Interior and tech

BYD’s own product page highlights several comfort and convenience features that explain why the Song Plus has been popular outside China. These include electrically adjustable front seats with heating and ventilation, a rotating central display, a digital 12.3-inch instrument panel, ambient lighting in 31 colors, wireless phone charging, dual-zone climate control, and a panoramic sunroof.

The cabin is designed to feel more premium than the price point suggests, which is important in a segment where buyers often compare it with Toyota RAV4, Honda CR-V, Hyundai Tucson, or other established family SUVs. In practice, the Song Plus is trying to offer a tech-heavy experience without demanding luxury-car money, and that is one reason it attracts first-time EV buyers and fleet users alike.

Safety equipment

Safety is one of the model’s strongest selling points. BYD lists adaptive cruise control with Stop & Go, blind-spot detection, traffic recognition, emergency braking, electronic stability control, pedestrian protection, a 360-degree panoramic camera, tire-pressure sensors, and ISOFIX child-seat mounts among the driver-assistance and safety features.

European crash-test reporting for the Song Plus/Seal U variant shows a five-star Euro NCAP result, with strong adult-occupant protection and good results across the major test categories. That matters because many Chinese SUVs have historically been judged mainly on price; the Song Plus shows that some newer models now compete on safety credentials too.

Range and charging

For the EV, range is the headline number, but you should read it carefully. BYD’s official materials show a 71.8 kWh Blade battery and a claimed 520 km range in one market, while another market brochure lists about 405 km WLTC for the EV version. In real-world use, high-speed travel, air-conditioning, steep terrain, and heavy loads will reduce usable range, so the official figure should be treated as a benchmark, not a promise.

The DM-i version is easier to live with on longer journeys because it can run on electric power for short urban trips and then rely on petrol for extended driving. Official market data shows 3.3 kW AC charging for the hybrid and up to 26 kW DC charging on the higher-capacity DM-i trim, which makes charging speed dependent on trim and regional specification.

Ownership implications

• EV owners should pay close attention to home charging, charger compatibility, and battery-health management.
• DM-i owners should monitor both fuel economy and charging habits, because the hybrid is most efficient when the battery is actually used and recharged regularly.
• If your weekly driving includes long highway trips, the DM-i usually feels less restrictive than a full EV.

Driving experience

The Song Plus is not trying to be a sports SUV. Instead, it focuses on smooth acceleration, quiet operation, and easy daily usability, with the DM-i’s 7.7-second 0-100 km/h time showing that it is quick enough for ordinary traffic without being a performance model. The EV, with its instant motor torque, should feel even more responsive in city driving, especially from traffic lights and during overtaking.

The turning radius of 5.55 meters is useful in crowded cities and tight parking lots. That makes the Song Plus easier to live with than some larger SUVs, particularly in dense urban markets where parking space is limited and U-turns happen often.

Market positioning

The Song Plus competes in a crowded segment, but its advantage is that it gives you two different solutions under one nameplate. The DM-i version is closer to a fuel-saving all-rounder, while the EV version is a cleaner battery-electric SUV with a more direct ownership model.

This is also why many global buyers cross-shop it with the BYD Seal U name used in some markets. The architecture and positioning are closely related, and the European Seal U naming has helped BYD position the model as a mainstream family SUV rather than a niche EV experiment.

Buying guide

When I compare the two versions, I look at three questions: where will you charge, how far do you drive daily, and how often do you leave your local area. If your routine is mostly urban and you can charge reliably, the EV offers the cleanest ownership pattern; if your trips are mixed or charging is unreliable, the DM-i is the safer fit.

A practical buyer should also check the market-specific battery size, charging speed, trim level, and warranty before buying. BYD’s Song Plus DM-i documentation lists a 6-year / 150,000 km vehicle warranty in one overseas market, but warranties can vary by importer and country, so that document should be confirmed locally before purchase.

Simple decision table

Tools that help

On Naira.autos, the Evaluate Used Car tool is useful if you are comparing a pre-owned Song Plus against other imported SUVs, because it helps you structure a condition check before you commit to a purchase. The VIN Checker Global tool is also valuable for verifying identity details on imported units, especially when the car is coming from a market that uses different trim names or spec packages.

If you are deciding between the Song Plus DM-i and the EV, the Car Comparison tool is the most practical next step because it lets you line up range, charging, fuel use, and equipment side by side. For buyers who are still uncertain about whether they need a PHEV or a full EV, the Song Plus is a strong test case for comparing real-world ownership trade-offs rather than brochure numbers alone.

Conclusion

The BYD Song Plus is a well-rounded SUV because it gives buyers a credible plug-in hybrid option and a full-electric option in the same model family, with strong cabin tech, useful dimensions, and safety credentials that include a five-star Euro NCAP result for the Seal U/Song Plus variant. If you want maximum flexibility, the DM-i is the easier choice; if you want the cleanest daily driving experience and dependable charging access, the EV is the better fit.
