MG PHEVs Get SolidCore Batteries and New e-CVT Hybrid

MG SolidCore Semi-Solid-State Battery and e-CVT Hybrid Powertrain

MG Motor’s new plug-in hybrid (PHEV) technology combines a SolidCore semi-solid-state battery with a Toyota-style e-CVT transmission, targeting improved energy density, faster charging, and smoother power delivery for Malaysian drivers seeking a balance between electric efficiency and petrol range. The system is developed by SAIC Motor, MG’s parent company, and is expected to be offered in models such as the MG HS and MG ZS PHEVs. In Malaysia, MG vehicles are distributed by MG Motor Malaysia, with official service centres in the Klang Valley, Penang, and Johor. The technology addresses the common pain point of limited electric-only range in conventional PHEVs, offering a claimed 30% higher energy density than standard lithium-ion packs, which translates to an estimated 80–100 km of all-electric driving under NEDC conditions. For Malaysian users, this means fewer charging stops and lower running costs, especially for daily commutes in urban areas like Kuala Lumpur.

Key Facts

What Is the SolidCore Semi-Solid-State Battery?

The SolidCore battery is a semi-solid-state design that replaces the liquid electrolyte in conventional lithium-ion cells with a gel-like solid electrolyte, increasing energy density and reducing fire risk. According to SAIC Motor, the technology uses a proprietary solid electrolyte composite that allows lithium ions to move more efficiently, enabling faster charging and a longer cycle life. In a press release, MG stated: “SolidCore represents a significant step toward full solid-state batteries, offering 30% higher energy density and 50% faster DC charging compared to current PHEV batteries.” For Malaysian conditions, the battery’s thermal management system is designed to operate reliably in ambient temperatures up to 45°C, which is critical for tropical climates. The semi-solid state also reduces the risk of thermal runaway, a key safety advantage for vehicles parked in direct sunlight.

How Does the New e-CVT Hybrid Powertrain Work?

The e-CVT transmission uses a planetary gearset to continuously vary the ratio between the petrol engine and electric motor, eliminating the need for traditional gears and providing seamless acceleration. This design is functionally identical to Toyota’s Hybrid Synergy Drive, but MG has tuned it for plug-in hybrid operation. The system can operate in three modes: EV-only (up to 100 km), series hybrid (engine acts as generator), and parallel hybrid (engine and motor both drive the wheels). In Malaysian stop-and-go traffic, the e-CVT allows the petrol engine to run at its most efficient RPM, reducing fuel consumption by an estimated 15–20% compared to a conventional automatic PHEV. The combined output is expected to be around 200–250 hp, sufficient for highway cruising on the PLUS Expressway.

This e-CVT system is fully compatible with MG’s existing PHEV architecture and will debut in the 2027 MG HS PHEV.

When Will MG PHEVs with SolidCore Be Available in Malaysia?

MG Motor Malaysia has not announced a firm launch date, but industry sources indicate that the first SolidCore-equipped PHEV models could arrive in Malaysian showrooms by the fourth quarter of 2026. The timeline depends on homologation and local testing, which includes SIRIM certification for the battery and charging system. MG Malaysia is currently expanding its dealer network to 15 outlets nationwide, with service centres in major cities. Pricing is expected to be competitive with other C-segment PHEVs such as the Honda CR-V e:PHEV and the BYD Sealion 6 DM-i, with an estimated starting price of RM 150,000 to RM 180,000 (excluding insurance).

Malaysian buyers can expect a 5-year vehicle warranty and an 8-year battery warranty, subject to final terms.

Who Is This For in Malaysia?

The MG PHEV with SolidCore battery and e-CVT is ideal for urban commuters in the Klang Valley who want to reduce fuel costs without range anxiety, and for families who need a spacious SUV for weekend trips. The 80–100 km electric range covers the average daily commute of 40–60 km in Kuala Lumpur, meaning many users can drive purely on electricity for most days. The e-CVT provides smooth, jerk-free driving in congested traffic, and the semi-solid-state battery is less prone to degradation in hot weather compared to standard lithium-ion packs. For those living in condominiums with limited charging access, the ability to charge via a standard 240V wall socket (Type 2) is a practical advantage. However, the vehicle still requires a petrol engine for longer journeys, making it a transitional solution for Malaysian drivers not yet ready for a full battery electric vehicle (BEV).

This PHEV technology is particularly suited to Malaysian households with access to home charging and a need for a single car that can handle both city and highway driving.

Common Questions

Can I charge the MG PHEV using a standard 240V wall socket in Malaysia?

Yes. The MG PHEV comes with a Type 2 AC charger that can be plugged into a standard 240V, 13A UK-style socket. A full charge from empty takes approximately 4–5 hours using the supplied 7.2 kW onboard charger.

Is the SolidCore battery safe in Malaysia’s hot and humid climate?

Yes. The semi-solid-state electrolyte is less flammable than liquid electrolytes, and the battery pack includes active liquid cooling to maintain temperatures below 40°C even in ambient conditions up to 45°C. MG has conducted tropical climate testing in Thailand and Malaysia.

How does the e-CVT compare to a traditional automatic transmission in terms of driving feel?

The e-CVT provides a continuously smooth acceleration without gear shifts, which can feel unusual at first. However, it eliminates the “rubber band” sensation of some CVTs by using a planetary gearset that directly couples the engine and motor, giving a more direct response.
