Frequently Asked Questions

The BYD Sealion 7 is a mid-size electric SUV positioned between the smaller BYD Atto 3 and the larger BYD Tang. It’s designed to compete directly with models like the Tesla Model Y, Hyundai Ioniq 5, and Kia EV6, offering strong performance, modern technology, and BYD’s in-house Blade Battery system.
The BYD Sealion 7 is available in multiple trims, ranging from rear-wheel drive to dual-motor all-wheel drive. Power output spans 230 – 390 kW, torque ranges 380 – 690 Nm, and 0–100 km/h times vary from 3.8 to 9.6 seconds depending on trim. Top speed is 215 km/h, and price in Europe ranges between €47,000 and €59,000.
Depending on configuration, the BYD Sealion 7 provides between 405 km and 440 km of driving range (WLTP). Real-world tests by reviewers suggest an average of around 400 km under mixed conditions, depending on tire choice and driving style.
It uses BYD’s proprietary Blade LFP (Lithium Iron Phosphate) battery, known for long life, high safety, and thermal stability. Capacity varies between 82.5 kWh and 91.3 kWh, and it supports Level 3 DC fast charging (24–32 minutes 10–80%) and Level 2 AC charging (9–9 h 45 min full).
In independent tests, the dual-motor BYD Sealion 7 Performance achieved 0–100 km/h in 4.3 seconds, matching its official claim. Reviewers describe the acceleration as strong yet progressive, making it suitable for both city and highway use.
The BYD Sealion 7 prioritizes comfort over sportiness. Its double-wishbone front and multi-link rear suspension offer a smooth ride on rough roads, but expert reviews mention soft body control and a floaty feel at higher speeds. Stability control can intervene early during sharp cornering.
Inside, the BYD Sealion 7 features soft-touch leatherette, a rotating 15.6-inch touchscreen, and a 12-speaker Dynaudio sound system. Reviewers consistently highlight the cabin’s premium finish, ample rear-seat legroom, panoramic roof, and high perceived build quality for its price range.
The BYD Sealion 7 comes with adaptive cruise control, lane-keeping assist, blind-spot detection, 360° HD cameras, and a head-up display in higher trims. While the driver-assist systems work well on highways, testers found the lane-centering less reliable in outer lanes.
Energy consumption averages around 20–21 kWh/100 km, slightly higher than competitors like the Tesla Model Y. Reviewers attribute this to its heavier weight and grippier performance tires, but they note its efficiency remains acceptable for a mid-size AWD electric SUV.
Strengths include excellent build quality, strong acceleration, comfortable ride, and advanced safety systems. Common criticisms are its soft suspension tuning, limited steering feedback, and higher energy use. Overall, the BYD Sealion 7 is praised as a refined, high-value Chinese EV that combines performance, technology, and comfort effectively.

Pros & Cons

Pros:

Owners and reviewers consistently note the Sealion 7’s solid construction, tight panel gaps and premium-feeling cabin materials for a Chinese EV.
In its AWD performance version the Sealion 7 delivers rapid acceleration (e.g., 0-100 km/h in ~4.3-4.5 s), putting it among the fastest mid-size electric SUVs at its price point.
Large rear space, usable boot (≈500 L+), frunk storage, and premium tech features make it practical for families.
Use of the Blade LFP battery provides good durability, and the vehicle supports comparatively fast DC charging and convenient home AC charging.
Reports show it achieving five-star safety ratings, with a rich set of ADAS and driver aids — strong for the class.
Many forum users mention that for the features offered the Sealion 7 delivers more tech or space than some rivals at similar cost.
Reviewers highlight the quiet cabin and comfortable ride in regular driving conditions, especially for everyday use.

Cons:

Multiple reviews observe that while the Sealion 7 accelerates strongly, its suspension/steering tuning is softer, body roll more noticeable, and it lacks the driving crispness of class competitors.
Forums and reviews point out that the real-world range falls short of some rivals, attributed to its weight and tyre choice, which may affect long-haul use.
While comfortable in everyday use, the soft suspension and large wheels can lead to floaty or less composed behaviour on undulating/highway surfaces.
Owners report that certain tech features (smartphone app functionality, software polish, switchgear for functions) are not as smooth or fully refined as established premium brands.
While not a fault of the vehicle’s performance, many buyers note the “Chinese EV” label means perception, resale trust or brand prestige may lag established brands.
