The MG 4X represents an exciting expansion of MG’s popular MG4 family into the compact electric SUV segment. Recently unveiled in China ahead of its official debut (likely at events like Auto China 2026), the MG 4X builds on the proven Modular Scalable Platform (MSP) that underpins the MG4 hatchback, but shifts to a higher-riding crossover body style for added versatility and appeal to urban buyers seeking more ground clearance and practicality.
Measuring 4,395 mm in length, 1,842 mm in width, 1,551 mm in height, and boasting a generous 2,750 mm wheelbase, the MG 4X offers a spacious and balanced footprint in the subcompact EV SUV class. This longer wheelbase promises ample interior room, particularly for rear passengers, while the dimensions provide a commanding presence on the road without venturing into larger mid-size territory.
A standout highlight is its adoption of advanced semi-solid-state battery technology (also referred to as liquid-solid-state in some reports). The entry-level variant features a 53.95 kWh pack, delivering an impressive claimed range of up to 510 km under China’s CLTC testing cycle. This battery chemistry enhances thermal stability, reduces fire risk compared to traditional lithium-ion setups, and performs better in extreme temperatures—making it a forward-thinking choice for real-world reliability.
Positioned strategically within the MG lineup, the MG 4X sits below the larger MG S5 (also known as MG ES5 in some markets) and aligns as an entry-level SUV option in the MG4 family. This hierarchy allows MG to offer buyers a progression from the compact MG4 hatchback to the more rugged 4X, then up to the bigger S5 for those needing extra size or features.
The MG 4X enters a fiercely competitive space, with the BYD Atto 2 emerging as its most immediate rival in the compact EV SUV category. Both models target young, tech-savvy urban drivers looking for affordable, efficient electric crossovers.Here’s a quick dimensions comparison:
- Length: MG 4X (4,395 mm) vs. BYD Atto 2 (4,310 mm) — MG is longer by about 85 mm.
- Width: MG 4X (1,842 mm) vs. BYD Atto 2 (1,830 mm) — MG is slightly wider by 12 mm.
- Height: MG 4X (1,551 mm) vs. BYD Atto 2 (1,675 mm) — Atto 2 is taller by around 124 mm, giving it a more traditional SUV-like stance with potentially better ground clearance perception.
- Wheelbase: MG 4X (2,750 mm) vs. BYD Atto 2 (2,620 mm) — MG’s longer wheelbase could translate to superior rear legroom and interior packaging.
In terms of length and width, the MG 4X appears larger and more stretched out, potentially offering a sleeker profile and better high-speed stability. However, the BYD Atto 2’s extra height contributes to a more upright, crossover-oriented look that some buyers prefer for everyday practicality and visibility.
Both vehicles leverage cutting-edge EV platforms—the MG 4X with its semi-solid-state battery innovation and the Atto 2 built on BYD’s efficient e-Platform 3.0—promising strong efficiency, quick charging, and competitive range in real-world use.
As the MG 4X rolls out (with production expected in the second half of 2026 and potential global expansion), it positions MG as a serious contender against dominant players like BYD. Whether it matches or exceeds the Atto 2 in pricing, features, or driving dynamics will depend on final market specs, but early signs point to a compelling battle in the affordable EV SUV space. Expect more details on performance, pricing, and availability as the model nears full launch.
