The Evolution of the Deepal SL03: Changan’s High-Tech Electric Sedan Pioneer

Deepal

The Deepal SL03 is one of the most significant new-energy vehicles to emerge from China in the early 2020s. Introduced in 2022 as the first model from Changan’s Deepal (formerly Shenlan) brand, the SL03 represents a bold step into electrification, combining advanced battery-electric, range-extended, and even hydrogen-powered technologies within a single platform.

Since its debut, the SL03 has evolved through multiple model years, trim restructures, and technological updates, while also spawning related models such as the L07. This article explores its full evolution, including production years, trims, variants, and future outlook.

Origins and Brand Background

The SL03 was developed under Changan Automobile’s new energy division, which was reorganized between 2020 and 2022 into what became Deepal Automobile Technology. The model (internally codenamed C385) was the first production vehicle under the brand and marked Changan’s serious push into the EV market.

The SL03 debuted in mid-2022 and entered production later that year, establishing itself as a mid-size liftback sedan designed to compete with vehicles like the Tesla Model 3.
