Design and Interior

Exterior Styling

The BYD Seal cuts a distinctive figure on UK roads, with its sleek, aerodynamic profile and contemporary design language. Reviewers consistently praise the Seal’s smart, neat styling, which manages to look premium without appearing derivative. The car’s proportions are well-balanced, with a low-slung roofline that hints at its performance capabilities while maintaining practical headroom inside.

Compared to the Tesla Model 3, the Seal offers a more conventional aesthetic that many buyers find appealing. The design avoids the minimalist extremes of some competitors, instead presenting a cohesive, modern appearance that feels both fresh and familiar. Build quality appears solid, with consistent panel gaps and high-quality paint finishes that match expectations for this price point.

Interior Design and Materials

Step inside the BYD Seal, and you’re greeted by an interior that feels genuinely premium. The cabin makes excellent use of materials, with soft-touch surfaces, quality leather upholstery, and thoughtful attention to detail throughout. The overall ambience is more luxurious than the Tesla Model 3, with a warmer, more inviting feel that European buyers particularly appreciate.

Practicality is well-considered, with comfortable seating for five adults and reasonable headroom despite the coupe-like roofline. The driving position is excellent, with good visibility—a notable advantage over the Model 3, which suffers from limited rearward visibility. Physical controls remain present, including traditional stalks for indicators and wipers, which many drivers prefer over Tesla’s button-based steering wheel controls.

Technology and Infotainment

The BYD Seal’s party piece is its 15.6-inch rotating touchscreen, which can pivot between portrait and landscape orientations. This unique feature allows drivers to optimize the display for different functions—portrait for navigation, landscape for media. The screen itself is crisp and responsive, with good brightness and viewing angles.

However, the infotainment system represents one of the Seal’s weaker points. Reviewers consistently note confusing menu hierarchies and a lack of intuitive organization. While the system includes Apple CarPlay and Android Auto support (unlike the Model 3), navigating the native interface can be frustrating. The 10.25-inch digital instrument cluster provides clear information, but the overall user experience needs refinement.

Standard equipment is generous across both trims. Every Seal includes a panoramic sunroof, 19-inch alloy wheels, heated and cooled front seats, a heated steering wheel, wireless phone charging, a 12-speaker Dynaudio sound system, and a 360-degree camera system. This level of standard equipment significantly exceeds what’s typically included at this price point.

Performance and Driving Experience

Powertrain Options

The BYD Seal offers two distinct powertrain configurations in the UK market. The entry-level Design trim features a single rear-mounted motor producing 204 hp, driving the rear wheels. This setup provides adequate performance for most driving scenarios, with a 0-62 mph time of 5.9 seconds that feels brisk in real-world conditions.

The Excellence trim elevates performance dramatically with dual motors and all-wheel drive. Output ranges from 523 to 530 hp depending on the specific model year, delivering genuinely impressive acceleration. The claimed 0-62 mph time of 3.8 seconds feels conservative—independent testing has recorded times as low as 3.3 seconds, placing the Seal in the same performance bracket as the Tesla Model 3 Performance.

Acceleration and Top Speed

Behind the wheel, the Excellence AWD model delivers neck-snapping acceleration that never fails to impress. The instant torque delivery characteristic of electric motors is put to excellent use here, with seamless power delivery that makes overtaking effortless. The car feels genuinely quick, with acceleration that pins occupants to their seats during hard launches.

However, the Seal’s performance credentials don’t translate into sporty handling. Despite the impressive power output, the car is clearly tuned for comfort rather than dynamic driving. The suspension prioritizes ride quality over body control, resulting in noticeable body roll during spirited cornering. The steering, while accurate, feels somewhat distant and lacks the feedback that driving enthusiasts crave.

Ride and Handling

The BYD Seal excels in ride comfort, with a suspension setup that effectively absorbs road imperfections and provides a refined, quiet driving experience. Motorway cruising is particularly impressive, with minimal wind and road noise intruding into the cabin. The car feels stable and composed at speed, instilling confidence during long-distance journeys.

Where the Seal falls short is in its handling dynamics. While perfectly capable for everyday driving, the car lacks the sharpness and precision found in premium European rivals like the BMW i4 or Mercedes-Benz EQE. Body control could be tighter, and the chassis doesn’t encourage enthusiastic driving in the way that some competitors do. For buyers seeking a comfortable, refined electric sedan, this won’t be an issue. Those prioritizing driving engagement may find the Seal somewhat disappointing.

Range and Charging

Battery and Range

The BYD Seal utilizes BYD’s proprietary Blade Battery technology, which uses lithium iron phosphate (LFP) chemistry. This offers several advantages, including improved safety characteristics, longer cycle life, and better thermal stability compared to traditional lithium-ion batteries.

The Design trim features a 61.44 kWh battery pack, delivering a WLTP range of 317 miles. Real-world testing suggests owners can expect approximately 280-300 miles of range in typical UK driving conditions. The Excellence trim upgrades to an 82.56 kWh battery, with WLTP figures of 354 miles for the RWD version and 323 miles for the AWD model. Real-world range typically falls between 300-320 miles, depending on driving style and conditions.

Efficiency is competitive but not class-leading. The Seal achieves approximately 4.5 miles per kWh, slightly behind the Tesla Model 3’s 4.7 miles per kWh. This difference becomes more noticeable during long-distance journeys, though for most UK drivers, the Seal’s range will prove more than sufficient for daily needs.

Charging Capabilities

The BYD Seal supports DC fast charging at up to 150 kW, allowing the battery to charge from 10-80% in approximately 37 minutes under ideal conditions. This places the Seal slightly behind some competitors—the Tesla Model 3 supports up to 170 kW charging, while newer models like the Hyundai Ioniq 6 can accept up to 235 kW.

For home charging, the Seal accepts AC charging at up to 7.2 kW, requiring 12-16 hours for a full charge from empty. This is typical for the segment and perfectly adequate for overnight charging. The car also supports three-phase AC charging for faster home installations where available.

Recent facelift versions have introduced an upgraded 800V electrical architecture, reducing 10-80% charging times to just 25 minutes. However, this upgrade’s availability in the UK market remains unclear at the time of writing. Buyers should verify the specific charging capabilities of their chosen model year.

Technology and Features

Beyond the infotainment system, the BYD Seal includes an impressive array of technology features. The panoramic sunroof creates an airy, open feeling in the cabin, while the 360-degree camera system makes parking and maneuvering in tight spaces significantly easier. The Dynaudio sound system delivers excellent audio quality, with clear highs and substantial bass that enhances the driving experience.

Driver assistance systems are comprehensive, including autonomous emergency braking with pedestrian and cyclist recognition, lane keeping assist, intelligent speed limit assist, and an advanced eCall emergency system. However, some reviewers note that these systems can be overly intrusive, with traffic sign recognition generating frequent warnings that some drivers find annoying.

The car includes remote pre-conditioning capabilities, allowing owners to heat or cool the cabin before entering the vehicle. This feature proves particularly valuable during UK winters, ensuring a comfortable interior regardless of external temperatures. Wireless phone charging and multiple USB-C ports ensure devices stay powered throughout journeys.

Safety

Euro NCAP Rating

The BYD Seal achieved a maximum 5-star Euro NCAP safety rating, providing peace of mind for families and safety-conscious buyers. The car scored 89% for adult occupant protection, 87% for child occupant protection, 82% for vulnerable road user protection, and 76% for safety assistance systems. Updated versions (SEAL 6 DM-i) have improved these scores to 92%, 90%, 84%, and 85% respectively.

The Seal earned maximum points in side barrier and side pole impact tests, demonstrating excellent structural integrity. Child protection also received full marks in frontal offset and side barrier evaluations, making the Seal an excellent choice for families.

Safety Features and Technology

The Seal’s safety credentials stem from its advanced structural design, which incorporates Cell-to-Body (CTB) technology that integrates the battery pack into the vehicle’s structure. This approach increases torsional rigidity to 40,500 N.m/degree, creating a stiffer chassis that better protects occupants during collisions.

Active safety systems include autonomous emergency braking that can detect and respond to pedestrians and cyclists, lane keeping assist with lane departure correction, and a door-opening warning system that alerts occupants to approaching cyclists—particularly valuable in urban environments. The intelligent speed limit assist helps drivers comply with speed restrictions, though some find its warnings excessive.

Pricing and Trims

UK Pricing

The BYD Seal is available in two trim levels in the UK market. The Design trim starts at £45,730 on the road, featuring the single-motor rear-wheel-drive powertrain. This represents a significant premium over the Tesla Model 3 RWD, which starts at £39,990. However, the Seal includes substantially more standard equipment, helping to justify the price difference.

The Excellence trim, priced at £48,730, adds the dual-motor all-wheel-drive powertrain and enhanced performance. This positions the Seal competitively against the Tesla Model 3 Long Range AWD, which costs £49,990. The Excellence trim offers exceptional value for buyers seeking maximum performance, delivering Model 3 Performance-level acceleration at a lower price point.

Financing Options

BYD offers attractive PCP finance deals with a representative APR of 1.9%, making the Seal more accessible to buyers who prefer monthly payments over outright purchase. The Design trim requires a customer deposit of £2,999, while the Excellence trim requires £3,499. These competitive finance rates help offset the higher initial purchase price compared to some rivals.
