Update: ‘Interior,’ ‘First impressions’ and ‘TopElectricSUV says’ sections and ‘Australia (BYD Atto 4)’ sub-section of ‘BYD Seal global launch’ updated.

The BYD Seal (to be called the BYD Atto 4 overseas including Australia) is part of the brand’s ‘Ocean’ series of future EVs. The model will be available for purchase in select markets beginning in 2023. Here’s everything we know about the next-gen Chinese electric sedan:

Target customer

The BYD Seal is for customers who are on the market for a high-tech mid-size electric sedan like the Tesla Model 3 but with more affordable pricing. It’s also an attractive option against electric SUVs like the Tang and the Yuan Plus (Atto 3) for customers who seek the comfort and driving dynamics of a sedan. The pricing is also such that it seems a cheaper alternative to the brand’s own mid-size electric SUV.

Design

The Seal may look familiar if you’ve seen the Han EV, but it wears a distinctive exterior design inspired by the BYD Ocean X concept. The most attractive design feature in daylight is the car’s athletic proportions, particularly the tight rear end.

Front

At the front, the Seal features a low hood, slim headlamps with a Renault-style C-shaped extension below it, a smooth bumper, slanted vertical side air inlets in an artistic design, and an A-shaped compact lower air intake.

Side

The Seal flaunts a four-door-coupe look with a sleek roofline and a bow-shaped greenhouse. Arrow-shaped applique on the front quarter panels, flush door handles, smooth sculpting on the doors, water drop-like motif on the C-pillars (view on YouTube), and shark gill-like inserts in the rocker panels are the other noteworthy aspects of the sides.

Rear

At the rear, the new electric sedan has a full-width taillamp reminiscent of the Mercedes EQE, vertical side air outlets, a diffuser-style bumper, and separate reverse lights positioned alongside fog lights on the bumper.

Overall, the only downside is that the silhouette isn’t unique compared to rivals like the Tesla Model 3 and Nio ET5. The aerodynamic exterior should have a positive impact on energy consumption and cabin comfort, though. It will likely lead to a longer range, and fewer charging cycles would also mean prolonged battery life.

BYD Ocean series vs Dynasty series

BYD’s Ocean series features a more fluidic and aerodynamic design than its Dynasty series, which includes the Han EV. The new design language aligns with global design trends, to make them more competitive in the export markets as well. We observe added aggression, sportiness, sophistication, and a sense of premium character that is different from the Dynasty models. The Seal should also be the most aerodynamic and efficient model in the Ocean line-up.

The driver’s seat is 8-way electrically adjustable and includes 4-way electrically adjustable lumbar support and memory, ventilation, and heating functions as well. The front passenger’s seat offers 6-way electric adjustment, ventilation, and heating. There are two cupholders between the front seats and also between the rear outboard seats. A dual-zone automatic climate control system with a heat pump that reuses waste heat energy to reduce energy consumption and a PM2.5 air filtration system are standard features. Also included across the range is a panoramic sunroof that has a light sensor for automatically adjusting its transparency.

Interior

Seating and comfort

The BYD Seal offers premium seating for five occupants with sporty seats featuring ample side bolstering in the front and a luxurious bench in the back. Light blue dominates the interior, in line with the ocean theme of the model family, and the white seats feature light blue piping for a contrasting look. The door handles are shaped like a shell, and the Alcantara usage adds to the cabin’s premium appeal. Customers can comfortably load the luggage into the boot, which has a flat floor, thanks to a low loading lip and a wide aperture.

Features

The electric sedan features a minimalist interior with ocean-themed blue colors on various elements. It has a sleek dashboard with wide and curvy (outer-end) AC vents, a W-HUD, a 10.25-inch large digital instrument cluster, a wavy, bridge-type center console that houses a stubby drive selector, parking brake, two scrollers, a park assist button, and other drive controls, and NFC-based digital key. BYD-branded door sills, Qi wireless charging pad, and Dynadash audio system are other equipment highlights of the interior.

Infotainment

The Seal features a 15.6-inch tablet-style touchscreen infotainment system that tilts. The driver can change the orientation from landscape to portrait as per their preference. The 5G-enabled system includes BYD’s DiLink intelligent connected system that allows customers to install smartphone-like applications in the infotainment system.

Specifications

Platform

Underpinning the Seal is the bespoke BYD e-Platform 3.0, which supports RWD (like in the case of this sedan) and AWD electric drivetrain layouts. The platform would support short charging times, greater battery isolation from varying weather conditions, and long-range.

The new BYD EV has a double-wishbone suspension at the front and a five-link independent suspension at the rear. Though smaller than the Han EV, it has the same wheelbase, thanks to the dedicated EV platform. Customers will get a comparable room in a smaller footprint, and the smaller dimensions would help in maneuverability and parking.

Battery Life & Charging

The Seal is BYD’s first model to feature CTB (cell-to-body) battery technology. Integrating the battery into the body allows applying the sandwich structure, previously used for the battery pack, in the vehicle itself. The top cover of the battery pack is integrated into the floor of the vehicle’s body. CTB has led to a 100% increase in torsional stiffness (compared to conventional designs) – 40,000+ Nm/°.

The CTB layout has allowed raising the height of the chassis, which means the car is less prone to being damaged by bumps. Plus, the volume utilization is also better – 66%. Lastly, in case of a side collision, the higher stiffness should protect the car more.

Two battery pack capacity options are available to BYD Seal customers in China: 61.4 kWh and 82.5 kWh. The charging power (DC), depending on the configuration, is either 110 kW or 150 kW. The 30-80% charging time may not take more than 30 minutes.

Motor & Range

The 61.4 kWh battery pack is available in two 150 kW (201 hp) single-motor RWD configurations that deliver a range of 550 km (342 miles). A 0-100 km/h (0-100 km/h) sprint takes 7.5 seconds in the base variant. 110 kW is the maximum DC charging power, and in the peak rate, charging from 30 to 80% SoC takes 30 minutes.

The 82.5 kWh battery pack delivers a CLTC range of 700 km (435 miles) in a 230 kW (308 hp) single-motor RWD configuration and 650 km (404 miles) in a 390 kW (523 hp) dual-motor AWD configuration. The mid-level variant can accelerate from 0 to 100 km/h (0 to 62 mph) in 5.9 seconds, while the top-end variant can accomplish the same in just 3.8 seconds. These configurations allow DC fast-charging at up to 150 kW, but a 30-80% top-up takes the same time – 30 minutes.

iTAC

The Seal is BYD’s first car to feature its new iTAC technology. Short for “intelligence Torque Adaption Control,” the system aims to offer more traction than a conventional stability control system that uses wheel sensors to monitor speed changes and brakes to intervene when needed.

A wheel-speed sensor divides each turn of the wheel end into 32 or 48 acquisition bits. In iTAC, the wheel end of each turn can be divided into 4,096 bits, which means the speed and accuracy of the information collected are significantly higher. iTAC can adjust the torque delivery of the motor(s) in real-time as required. It can transfer part of or all the torque to the wheel with more grip and avoid triggering the ESP. When BYD tested on snow, it observed that vehicles with iTAC can accelerate from 0-60 km/h (0-97 mph) 0.7 seconds faster. Plus, when drifting, these vehicles don’t require excessive direction correction.

First impressions

Autohome took the BYD Seal for a test drive and was impressed with its performance. The mid-level variant, which is focused on maximizing range (700 km), offers superb acceleration, according to the Chinese publication.

There’s no wheel slip in a 0-100 km/h sprint; the car is buzzing with stamina at the start and maintains that till reaching the three-digit figure. The braking performance is surprisingly good, with just 35.9 meters of distance covered when stopping from 100 km/h. The Seal is an impressively quiet cabin, according to the Chinese publication. This is yet one more area where the Chinese sedan impresses.

Production

BYD makes the Seal in Changzhou (Jiangsu Province), China. The company could eventually manufacture 15,000 units of the new electric sedan every month (180,000 units yearly).

BYD has received more than 110,000 orders for the Seal since it started pre-sales in May 2022, pcauto.com.cn reported on July 29, 2022. In the event that this level of demand continues, BYD may have to expand Seal production considerably. At full tilt, the plant can produce 400,000 vehicles per year, so this shouldn’t be an issue. Furthermore, BYD has factories in Shenzhen, Changsha, and Shaoguan.

Analysts expect the Seal to create a splash and pose serious threats to popular electric mid-size sedans in China, as reported by CnEVPost. Xu Huixiong-led analyst team at Essence Securities has said that the Seal will likely be the most important BYD launch by far, potentially securing 30,000+ units in monthly sales. The upcoming model has significant advantages over Tesla’s Model 3, the team added. However, the proof of the pudding is in the eating!
