The BYD Seal (Chinese: 比亚迪海豹; pinyin: Bǐyǎdí Hǎibào) is a battery electric mid-size fastback sedan produced by BYD Auto. It is the second passenger car of BYD's latest "Ocean Series",[4] after the smaller hatchback BYD Dolphin.[5] The Seal is built on the e-Platform 3.0 and BYD's new 800-volt electrical platform.[4]

Two unrelated vehicles produced by BYD also uses the Seal nameplate. The Seal DM-i is a larger sedan with plug-in hybrid powertrain, and the Seal U is a renamed Song Plus EV for export markets.

Overview

The BYD Seal was announced in China in May 2022, with deliveries in August 2022. Its design was previewed as the BYD Ocean-X Concept in September 2021.[6] As part of the "Ocean Series" line of products, the Seal adopts many ocean-inspired design features. The exterior design features low hood, pop-out door handles, and long taillamp unit. The dashboard air vents of the Seal have a wavy pattern.[7]

The battery of the Seal is structural, giving the unibody chassis higher torsional rigidity (40,500 Nm/deg compared with an industry average of around 25,000) and a lower floor compared to other electric cars.[8] The Seal has a drag coefficient of just 0.219 Cd. BYD claims a 50:50 weight distribution between the front and the rear for the Performance AWD variant.[9]

The Seal is available with a rotatable 15.6-inch infotainment screen, 10.25-inch digital instrument panel, 12-speaker Dynaudio audio system, panoramic sunroof, quilted vegan leather upholstery, dual wireless smartphone chargers and heated and ventilated front seats. The Seal also has a 53-litre front trunk (frunk).[10][11] Some models are equipped with Intelligent Torque Adaption Control (iTAC) system (a torque vectoring system) and adaptive dampers.[10]

Powertrain

The Seal is equipped with either a 61.4 kWh or an 82.5 kWh LFP blade battery pack, which can be charged by a 220 V AC power source at 7 kW (11 kW in Europe),[3] or a DC fast charger at 110 or 150 kW (depending on the model). BYD claimed a domestic driving range between 550 and 700 kilometres (340 and 430 mi).[12] The battery pack reportedly can be fast charged from 30%-80% in 30 minutes, and the car has vehicle-to-grid capability.[5]

The Seal's top speed is limited to 180 kilometres per hour (110 mph),[13] and the 0–100 km/h acceleration is claimed to be around 7.5 seconds for the standard models and 3.8 seconds for its 4WD Performance model.[5] BYD claims the Seal AWD energy consumption is 12.7 kWh/100km.[7]
