BYD Seal (BYD Atto 4): What we know as of May 2022

Update: ‘Specifications’ and ‘Production & Release Date’ sections updated.

The BYD Seal electric sedan will be unveiled in China in the following weeks. The Seal (to be called the BYD Atto 4 overseas) is part of the brand’s ‘Ocean’ series of future EVs, according to its product plan reported by on December 24, 2021.


The BYD 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. Data from China’s Ministry of Industry and Information Technology (MIIT) leaked the exterior in March. A silver unit was spotted completely uncovered in China on a flatbed at the end of April. The most attractive design feature in daylight is the car’s athletic proportions, particularly the tight rear end.

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.

The Seal flaunts a four-door-coupe look with a sleek roofline and a bow-shaped greenhouse. Flush door handles, smooth sculpting on the doors, and shark gill-like inserts in the rocker panels are the other noteworthy aspects on the side. At the rear, the upcoming electric sedan has a full-width taillamp reminiscent of the Mercedes EQE, vertical side air outlets, and separate reverse lights positioned alongside fog lights on the bumper.


The BYD Seal 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 15.6-inch tablet-style touchscreen infotainment system, a large digital instrument cluster, and a wavy, bridge-type center console. The delicate door handles are shaped like a shell, and the Alcantara usage adds to the cabin’s premium appeal. Dynadash audio system is an equipment highlight of the interior.


According to Chinese media reports, underpinning the BYD Seal is the bespoke e-Platform 3.0, which supports RWD and AWD electric drivetrain layouts. The platform would support short charging times, greater battery isolation from varying weather conditions, and long-range.

Chinese reports say that the Seal could be BYD’s first car to feature its new iTAC technology. Short for “intelligence Torque Adaption Control,” the new system aims to offer more traction than 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 try to avoid triggering the ESP. When BYD did testing in the snow, it saw 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.

MIIT data suggests that the Seal will be available in two single-motor RWD variants and a dual-motor AWD variant. The base RWD variant will have a 150 kW motor, and the higher-end RWD variant will use a 180 kW motor. The dual-motor AWD variant will employ a 160 kW motor at the front and a 230 kW motor at the rear. The top speed of all three variants will be the same – 180 km/h.

The Seal will be BYD’s first model to feature CTB (cell-to-body) battery technology. CTB could mean more space and more safety compared to a traditional battery technology in which there are separate modules consisting of cells and the pack forming from these modules isn’t a part of the vehicle’s structure. There’s no word on the energy storage capacity or range of the Seal yet.

BYD Seal Price & Rivals

Expect BYD Seal price to be in the region of CNY 220,000 (USD 32,715) and CNY 280,000 (USD 41,637). At this price, expect the BYD Seal to lock horns with the Xpeng P5, which retails from CNY 177,900 (USD 26,454). It might also compete with the more expensive Tesla Model 3, which retails from CNY 279,900 (USD 41,622).

BYD’s own Han EV sedan that starts at CNY 214,800 (USD 31,941) might get cannibalized. There would be competition from BYD’s Japanese partners as well. Toyota is developing a Corolla-like sedan (Toyota bZ3/bZ4) powered by the BYD Blade battery, becoming the Seal’s future rival.

Production & Release Date

Pre-sales of the BYD Seal will start in China on May 20, 2022. Sales may commence sometime in the second half of the year. BYD has already gone live with the pre-launch marketing campaign of the Seal ahead of its world premiere. On March 18, 2022, the company released a teaser of the upcoming electric vehicle on its Weibo account. The video revealed a sleek design with Renault-style C-shaped daytime running lights and sci-fi-style light guides integrated into the bumper.

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.

As per’s report on February 8, 2022, the Seal will be manufactured at the brand’s Changzhou plant in China, with a production capacity of 5,000 units per month or 60,000 units per year initially. The plant can roll out 400,000 units a year while running at maximum capacity. BYD also has three other manufacturing plants in Shenzen, Changsha, and Shaoguan.

BYD entered Europe via Norway in 2021, launching its first passenger car, the BYD Tang EV. The Warren Buffet-backed Chinese automaker should expand its global range to include the BYD Yuan Plus (Atto 3) and the BYD Seal while entering new EU markets within a couple of years.

Seal to launch in Australia as the BYD Atto 4

The BYD Seal has been confirmed for Australia. It may be launched under the ‘Atto 4’ moniker, according to The Driven‘s report dated March 15, 2022. The Seal will join the Dolphin (possibly the Atto 2 in Australia), another BYD EV confirmed for the Australian market. BYD cars are imported to Australia via EV Direct, which has earned the distribution rights for BYD EVs on the continent. The company is targeting customer deliveries around March 2023, with pre-orders opening around October 2022.

EV Direct’s CEO, Luke Todd, stated that the Seal would not only rival the Tesla Model 3 but also take on electric sports cars, as reported by The Driven. It’s unlikely for the BYD Atto 4 to impact sports car sales in Australia or globally. EVs inherently pack strong acceleration, and the Seal doesn’t seem exceptional in this department. It’s unlikely to deliver the thrills of a Model S Plaid or even the Lucid Air Dream Edition, two EVs that pack top performance and are yet marketed as performance/luxury ‘sedans’ and not sports cars.
