BYD SEAL here by year end

Published on 06th September 2023 at 14:14

Already here with their impressive C-segment SUV, the ATTO3, BYD have just given 
the world a glimpse of their next full EV, the friendly-named, D-segment saloon, 
SEAL. The first BYD SEAL’s will be in dealerships in O4 2023 with end-user 
customer deliveries from November. Customers can choose from two powertrain 
variants, two trim levels (BYD SEAL Excellence-AWD and BYD SEAL Design), six 
body colours and two interior trim colours. 
Final prices will be announced in the run-up to the market launch, but it is expected 
they will start from €40,567 for the COMFORT model, arriving in 2024, based on 
current subsidies. 
First model to arrive in Ireland will be the DESIGN model, expected to be the most 
popular choice, and the EXCELLENCE model, both due here in Q4 2023 and starting 
from €44,036 and €49,836 respectively. 
All versions of the BYD SEAL are offered with impressive warranty conditions as 
standard, consisting of a six-year manufacturer’s warranty and eight years for the 
battery and electric motor. 
BYD is the fastest growing automaker worldwide, with a number of models already 
on sale to our European neighbours, the BYD HAN (E-segment sedan), the BYD 
TANG (E-segment SUV), and the BYD DOLPHIN (C-segment hatchback). 
The BYD SEAL is a sporty and dynamic D-segment saloon, the second in the BYD 
Ocean series, using BYD’s new ‘Ocean Aesthetics’ design language. It combines a 
sleek and athletic appearance with a high level of comfort and practicality for five 
occupants, an outstanding range of equipment, and dimensions that perfectly match 
the needs of European car buyers. Beyond that, the BYD SEAL features several 
technological firsts, resulting in countless benefits clearly distinguishing it from its 
Cell-to-Body technology 
Like the BYD ATTO 3 and the recently launched BYD DOLPHIN, the new BYD SEAL 
is based on BYD’s e-Platform 3.0, which is designed exclusively for pure-electric 
vehicles. Notably, the BYD SEAL is the first vehicle to implement BYD’s highly 
advanced Cell-to-Body (CTB) technology, which is an essential difference and 
ensures unprecedented levels of safety, torsional rigidity, driving dynamics and space 
Cell-to-Body means the battery is incorporated within the entire vehicle structure. It 
integrates the battery pack’s top cover with the traditional body floor structure. This 
forms a sandwich-like structure incorporating the top cover, the Blade Battery and 
the tray. In addition, the CTB architecture uses a high-strength honeycomb-like 
aluminium panel structure, further enhancing vehicle safety. 
The CTB battery system serves as a source of energy, as well as a structural 
component. It contributes to the BYD SEAL’s torsional stiffness of a massive 40,500 

Nm/degree, increasing handling limits and offering an excellent platform for 
comfort, cabin quietness, safety and performance. Furthermore, CTB technology also 
improves space utilisation as the battery is combined directly with the body, lowering 
the vehicle to the floor by about 15 mm. While reducing the body height, the CTB 
technology increases the axial height inside the vehicle, creating interior space. This 
has enabled the BYD SEAL to adopt a lower, sleek shape, with improved 
aerodynamic performance and striking visual impact, as well as more cabin space. 

BYD Blade Battery 
The BYD SEAL is equipped as standard with a Blade Battery, which BYD has been 
pioneering for over two decades. Now, 28 years on, with over five million new energy 
vehicles (BEV+PHEV) produced for customers, BYD is firmly established as a market 
leader in this field. Its revolutionary Blade Battery is born out of BYD’s relentless 
research and development, and considered as a major advancement for the EV 
The Blade Battery was developed in-house by BYD with the primary goal of 
optimising safety, durability, longevity, performance and space utilisation. The 
battery pack consists of 172 thin elongated cells that actually resemble blades. In 
addition, the Blade Battery uses lithium iron phosphate (LFP) as a cathode material, 
which offers a higher level of safety and durability compared with conventional 
lithium-ion batteries. 
Free of Cobalt 
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. 
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 
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). The range is set at 570 kilometres (WLTP 

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). The Excellence-AWD version has a range of 
520 kilometres (WLTP combined). 
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 
Drivers of the BYD SEAL Excellence-AWD will benefit from a newly developed 
Intelligent Torque Adaption Control system (iTAC). 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 
Four Driving Modes 
 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. 
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 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. T 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, with a 4G intelligent connection 

system that brings leading technology experiences and Over The Air (OTA) updates 
as a way to update infotainment features, are integrated in to the BYD SEAL. Drivers 
will have access to a 15.6 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. The driver will look onto 
a 10.25-inch full instrument LCD panel, while a 12-speaker Dynaudio Performance 
Audio System provides premium quality sound.
