BYD Seal (2024)

LFP batteries are 100% free of cobalt, a material that raises ethical and environmental concerns in the mining industry. In addition, LFP batteries are more resistant to extreme temperatures. They have better thermal stability and are less sensitive to temperature fluctuations, while they can withstand more charge and discharge cycles with hardly any loss of capacity. This makes these batteries particularly durable. With a height of only 110 mm for the entire battery pack, the Blade Battery also contributes to the efficient vehicle packaging and optimised interior space of the BYD SEAL.

In addition to all the benefits of the Cell-to-Body technology, the exceptional safety level of the Blade Battery is demonstrated (video) by exceeding the requirements of the punishing Nail Penetration Test. This is the most rigorous method to test battery thermal runaway and simulates the consequences of a serious road accident.

Furthermore, the BYD SEAL is offered as standard with a high-efficiency heat pump system. This allows for efficient regulation of the battery temperature via direct cooling and direct heating of the refrigerant, as well as control of the passenger compartment temperature with low energy consumption. The heat pump can also absorb waste heat from the electric powertrain, while it can withstand temperatures ranging from -30°C to 60°C. BYD's battery technology also supports V2L (Vehicle-to-Load), allowing the BYD SEAL to be used as a portable power supply for electrical devices (total output up to 3,000 W).

Range and performance

The progressive nature of BYD and the BYD SEAL goes beyond the Cell-to-Body technology and Blade Battery. For example, the new sports saloon uses the innovative 8-in-1 electric drivetrain. This integrates eight key components for propulsion, charging, control and management, enabling BYD to create exceptional opportunities for vertical integration within the supply chain, while significantly optimising space utilisation and energy efficiency.

Available in two trims, Design and Excellence-AWD, the all-new BYD SEAL will be offered with a choice of two drivetrains, both with a battery capacity of 82.5 kWh. The 'Design' single-motor version with rear-wheel drive (BYD SEAL Design) has a power output of 230 kW (313 PS) and accelerates from 0-62 mph in 5.9 seconds. The range is set at 354 miles (WLTP combined). The BYD SEAL is also available with four-wheel drive (BYD SEAL Excellence-AWD) with an electric motor on the front and rear axles (160 kW + 230 kW), resulting in a total power output of 390 kW (530 PS). This, the Excellence version, is a real powerhouse that accelerates from 0-62 mph in just 3.8 seconds, while the range is set at 323 miles (WLTP combined).

Customers of the BYD SEAL benefit from a high-voltage electric drive boost charging solution, which allows for faster charging. This technology innovatively uses the motor inductor to replace the boost inductor in the original boost solution, to meet the 420-750V voltage range of charging piles with high-power DC charging. During the charging process, the BYD SEAL reduces the heat generation of the charging and distribution assembly for more reliable performance.

The BYD SEAL offers an 11 kW 3-phase on-board charger for AC charging as standard, and can be fast charged at a DC ultra fast-charging station with 150 kW. With this amount of power, the battery can be charged from 30% to 80% in just 26 minutes.

Driving dynamics

Athletic, sporty and dynamic, as well as intelligent with a high-tech DNA, the new BYD SEAL has everything to impress European motorists. Its state-of-the-art vehicle architecture based on the e- Platform 3.0 with Cell-to-Body technology guarantees unprecedented torsional rigidity and a low centre of gravity, which fully benefits the driving dynamics of the BYD SEAL. In addition, the SEAL is the first BYD with independent suspension, with double wishbones at the front and a five-link rear suspension, which also contributes to the excellent handling and vehicle control.

The BYD SEAL Excellence-AWD offers variable frequency dampers for ultimate responsiveness. This technology controls the oil flow in the damper cylinder through the valve. When the road conditions are smooth, the damping is relatively firm, allowing for more stable vehicle dynamics and better handling. When there are potholes or rough surfaces, the damping automatically reduces to absorb the impact of the road better, assuring a high-quality ride.

In addition, the BYD SEAL Excellence-AWD benefits from a newly developed Intelligent Torque Adaption Control system (iTAC). This technology has changed the previous way of making the vehicle dynamically stable by reducing the power output, and upgraded it to torque shifting, appropriately reducing the torque or outputting negative torque, and other control methods to maintain the stability of the vehicle. Thanks to the improvement of recognition speed and the change of adjustment method, iTAC can integrate the own state of vehicles, as well as the driver's horizontal and vertical control needs to advance power distribution and adjustment, thereby, fully utilising the vehicle's power potential, improving safety and driving comfort while expanding handling limits.

The BYD SEAL offers four distinct driving modes, catering for a variety of driving preferences and conditions. These modes include:

• ECO mode, which prioritises energy efficiency and extends the driving range.
• Normal mode, providing a balanced driving experience for everyday use.
• Sport mode, emphasising performance through aggressive acceleration and sharper handling.
• Snow mode, designed to enhance traction and stability on slippery surfaces like snow or ice.

Ocean Aesthetics design language

After the BYD DOLPHIN, the new BYD SEAL is the second European model in BYD Ocean series to adopt the Ocean Aesthetics design language, giving it a dynamic, stylish and highly distinctive appearance.

The BYD SEAL has been created by a design team led by BYD's Global Design Director, Wolfgang Egger, and demonstrates power and athleticism with a drag coefficient of just 0.219 Cd. The low- to-the-ground body style slices like a razor blade through the wind. Its sleek nature-inspired design is emotionally rich, high-tech and appealing. The car's front end has a powerful sense of forward motion, with an 'X-face styling' in the dynamic perspective. The front of the BYD SEAL has the look and feel of a sports car, with its full, sculpted, captivating curves providing the sense of the momentum of waves.

The SEAL's side silhouette is smooth and natural, with a low front, sloping A-pillar, rounded roof, sloping fastback punctuated by a subtly upturned ducktail shape, which emphasises the characteristic of a sports coupe. The concealed door handle design, which is flush with the door when the vehicle is in motion, helps to enable airflow to pass at high speed, thereby reducing wind resistance and overall vehicle energy consumption.

Spacious and versatile

In addition to its dynamic, intelligent and sporty character, the BYD SEAL is also a versatile four- door sedan that comfortably seats five people. The 2,920 mm wheelbase provides occupants with legroom similar to that of an executive saloon. Meanwhile, due to the CTB architecture and compact battery packaging, occupants have plenty of headroom despite the car's low-slung styling.

The practicality is further reflected in the luggage compartment of 400 litres and an additional 53- litre 'frunk' under the bonnet (RWD-version). In addition, the BYD SEAL offers more than 20 flexible storage spaces for small items in the interior. At the front of the sub-dash, there is a wireless charging point for two mobile phones. In addition to the standard centre armrest box, there is a functional semi-open storage space under the sub-dashboard.

The front seats have a sporty appearance with soft and firm seat padding, and excellent wrapping and support. The driver's seat is electrically adjustable in eight directions, while users of all sizes can find a comfortable driving position behind the four-way adjustable steering wheel. The driver's seat has four-way power-adjustable lumbar support. The rear seats provide a comfortable seating position for three adult occupants. The seat back, cushion padding, as well as the angles of the rear seat back and cushion, have been ergonomically designed and fully optimised, easing any fatigue on long journeys. Occupants can also count on plenty of light in the interior thanks to an oversized panoramic sunroof. And for optimum comfort, the front doors are fitted with double layered laminated glass for excellent sound and heat insulation. The rear doors feature privacy glass, providing enhanced shade and privacy for rear occupants.

Infotainment and ADAS

Smart connectivity and leading infotainment are other primary elements of the BYD SEAL, which is equipped with a 4G intelligent connection system bringing leading technology experiences and Over The Air (OTA) updates as a way to update infotainment features. The BYD SEAL has a 15.6 inch rotatable screen equipped with intelligent voice control function that can be activated with the voice command "Hey BYD", and seamless smartphone integration via Android Auto or Apple CarPlay. It also features a 10.25-inch full instrument LCD panel, while the impressive 12-speaker Dynaudio Performance Audio System provides premium quality sound.
