The Evolution of the BYD Qin Plus: A Mass-Market Electrified Sedan Revolution

The BYD Qin Plus is one of the most important vehicles in the modern history of BYD Auto, representing the company’s transition from early plug-in hybrids to high-volume, affordable electrified sedans. Introduced in 2021 as a successor to the Qin Pro, the Qin Plus quickly became a cornerstone of BYD’s lineup, offering both plug-in hybrid (DM-i) and fully electric (EV) variants. Over the years, it has evolved through multiple updates, trim expansions, and technological improvements, becoming one of the best-selling new energy sedans in China.

This article explores the full evolution of the BYD Qin Plus, including production years, trims, variants, technological advancements, and future outlook.

Origins and Background (Pre-2021 Context)

The Qin Plus is part of the broader Qin lineage, which began in 2012 as one of the world’s early mass-produced plug-in hybrid sedans. The Qin series itself replaced the earlier F3DM and helped establish BYD as a leader in electrification.

By the late 2010s, the Qin Pro served as the primary model in the lineup. However, rapid advancements in battery and hybrid technology led BYD to develop a more refined and efficient successor—the Qin Plus.

Debut and Launch (2020–2021)

The BYD Qin Plus was first unveiled at the Guangzhou Auto Show in November 2020 and officially went on sale in March 2021.

Production Years

2021–Present (First Generation)

From launch, the Qin Plus was offered in two primary variants:

Qin Plus DM-i (plug-in hybrid)
Qin Plus EV (battery electric)

This dual-powertrain strategy allowed BYD to target both hybrid and fully electric buyers simultaneously.

Qin Plus DM-i (2021–Present)

Introduction of DM-i Technology

The Qin Plus DM-i debuted as one of the first vehicles to use BYD’s new DM-i hybrid system, designed to prioritize efficiency over performance.

Powertrain Overview

1.5-liter naturally aspirated gasoline engine
Electric motor with combined output up to ~145 kW
E-CVT transmission

Initial Trim Levels (2021)

The DM-i variant was offered in two primary configurations based on battery size:

55 km DM-i (Standard Range)
