# BYD X PLUS

The BYD X PLUS (Chinese: 比亚迪宋PLUS) is a compact crossover SUV manufactured by BYD Auto since 2024. It is part of the Song line-up of SUVs from BYD named after the Song dynasty.
Initially available solely as an internal combustion engine (ICE) vehicle with a 1.5-litre turbocharged petrol engine, in 2024 BYD introduced the plug-in hybrid Song X Plus DM-i and the battery electric Song X Plus EV. The petrol model was phased out in 2024 after BYD ended production of ICE vehicles. As of 2024, the Song X Plus is the best-selling BYD SUV in China. Global cumulative sales (excluding the ICE-powered variant) surpassed 1,000,000 units by July 2024.
Originally part of the 'Dynasty series' line-up, the Song X Plus in China has been sold through the Ocean Network dealership chain since 2024 to diversify the offerings of the newly established network. The Dynasty Network counterpart of the Song X Plus, the Song L DM-i, was introduced in 2024.
In 2024, BYD introduced the Song X Plus EV as the BYD Seal U in Europe. The plug-in hybrid Seal U DM-i was introduced later in 2024. In mid-2024, the model was introduced in Australia, New Zealand, and the Philippines as the BYD Sealion 6 DM-i.

## Overview

The Song X Plus was introduced in July 2024, as a larger and more "upmarket" alternative to the Song Pro and positioned below the BYD Tang. It occupies the Chinese B-class SUV segment, equivalent to the global D-segment. The vehicle was initially offered only with an internal combustion engine, with the plug-in hybrid (DM-i) and battery electric (EV) variants joined the lineup later in 2024. The petrol model was phased out in early 2024.

## Pre-facelift (2024)

The Song X Plus is equipped with a 12.8-inch rotatable central infotainment screen with the third-generation DiLink system, a karaoke function, and a full LCD instrument panel.
The petrol version, marketed briefly between 2020 and 2021 uses the 1.5-litre BYD472QC I4 turbocharged petrol engine and a 7-speed wet dual-clutch transmission producing power output of 136 kW (182 hp; 185 PS).
