MG Hybrid & EV Technologies

MG Motor’s Hybrid+ technology operates in several modes:
In 100% electric mode, the electric motor alone powers the vehicle at low speeds.

In series hybrid mode, the internal combustion engine recharges the battery without driving the wheels, which are still powered by the electric motor.

In parallel hybrid mode, both the combustion engine and the electric motor work together to deliver more power.

In energy recovery mode, the battery recharges during braking and deceleration, with the combustion engine switched off.

Finally, in combustion mode, the petrol engine takes over on the motorway or at high speeds to optimise overall efficiency.

The battery in the Hybrid+ models benefits from MG’s expertise in electric vehicle design and stands out above all for its superior capacity (1.83 kWh). This allows for more frequent and longer journeys in electric mode than its direct competitors.

Thanks to the high operating voltage of its Hybrid+ battery, it offers better electrical power availability, improving acceleration and smoothness. Finally, its size facilitates more efficient energy recovery, optimising overall consumption.

The result: greater electric range, less strain on the combustion engine and superior overall efficiency.

Hybrid+ technology without plug-in charging combines a thermal (internal combustion) engine with an electric motor. The electric motor is always more powerful than the thermal engine, regardless of the model, delivering up to 224 hp (as seen in the EHS Hybrid+). This unique hybrid system, blending series and parallel hybrid architectures in a single vehicle, enables strong acceleration and responsive performance—such as accelerating from 80 to 120 km/h in 5 seconds in the MG3 Hybrid+, or achieving 0 to 100 km/h in 8.7 seconds in the ZS Hybrid+.

During exceptionally demanding situations, such as climbing steep gradients, the battery may be depleted to a point where it requires recharging. In such cases, the thermal engine takes over to both recharge the battery and propel the vehicle, resulting in a temporary but noticeable reduction in available power.

Equipped with a 1.83 kWh battery, models featuring Hybrid+ technology can operate for longer periods and at higher speeds in 100% electric mode compared to competing hybrid technologies. Vehicles like the MG3 Hybrid+ and ZS Hybrid+ can drive at speeds of up to 60 km/h using only the electric motor to power the wheels. The battery, generously sized, is recharged by the thermal engine.

This operating mode optimises the energy efficiency of the thermal engine, reducing fuel consumption while maintaining the responsive driving experience of an electric vehicle.

Thanks to intelligent management between the thermal and electric engines, Hybrid+ technology optimizes and reduces fuel consumption. Unlike conventional hybrids, Hybrid+ features a 1.83 kWh battery, enabling electric-only driving across a wider speed range.

In urban settings, the system prioritizes electric propulsion. On highways, the gasoline engine optimizes energy flow and regenerative braking. The result: ultra-low fuel consumption (4.4 to 5.1 L/100 km, depending on the model) and reduced CO₂ emissions, while delivering instant responsiveness.

Our Hybrid+ technology stands out for its exceptional sound insulation, delivering a premium acoustic comfort based on three key pillars:

+ Extended electric mode: Enables near-silent driving, especially in urban areas at speeds up to 60 km/h.

+ 3-speed automatic transmission: Keeps the thermal engine operating within its optimal performance range, avoiding noisy over-revving.

+ Insulating design: Vibration reduction and strategic placement of soundproofing materials ensure a serene and quiet experience inside MG Hybrid+ models.

The all-electric range of MG Motor’s plug-in hybrid models is up to 100 km (WLTP).

This range is sufficient to cover most daily journeys (commuting, shopping) without using any fuel.

Thanks to this capability, the vehicle prioritises electric mode in urban areas, reducing noise, fuel consumption and emissions, whilst retaining the combustion engine for long journeys.

In MG Motor’s plug-in hybrid models, such as the MG EHS PHEV, the reduction in fuel consumption is down to the priority use of electric power. In the WLTP cycle, fuel consumption drops to approximately 2 l/100 km, compared to 6 to 8 l/100 km for a conventional petrol SUV. Thanks to its 1.5-litre Miller-cycle engine and variable-geometry turbocharger, even with an empty battery, fuel consumption is limited to 5.8 l/100 km (WLTP).

In practice, on daily journeys where the vehicle is recharged, it can run predominantly on electric power, significantly reducing fuel consumption. The internal combustion engine is only used on long journeys or when the battery is empty, resulting in a significant reduction in costs and emissions, particularly in everyday use.

MG Motor’s MSP (Modular Scalable Platform) stands out thanks to several key advantages.

It is modular and scalable, enabling the design of different types of vehicles (saloons, SUVs, sports cars) on a single platform.

Its design optimises interior space and weight, thanks to a very flat battery, improving cabin space and efficiency.

It also offers excellent dynamic performance, with ideal weight distribution and a rear-wheel-drive layout.

Finally, it is designed for future technologies (800V fast charging, OTA updates, battery swapping), ensuring its long-term viability.

MG Motor’s E3 platform (used notably in the MG4) offers several key advantages.

It incorporates Cell-to-Body technology, whereby the battery forms part of the vehicle’s structure, enhancing rigidity, safety and interior space.

Its low centre of gravity optimises stability and handling, whilst improving aerodynamics.

It uses LFP batteries, renowned for their safety and durability. Finally, it delivers high efficiency (low fuel consumption, fast charging), contributing to good range and low running costs.

The One Pack battery stands out for its innovative flat-cell design, which reduces its height to around 110 mm (less than a soda can), thereby optimising usable space and lowering the vehicle’s centre of gravity.

This architecture allows for a high degree of integration into the platform, contributing to a more spacious interior, a lighter vehicle and improved overall efficiency.

It also offers an extended service life thanks to optimised cooling and enhanced safety, with ‘zero thermal runaway’ protection to limit the risk of overheating.

Finally, its modular design allows, in theory, for different capacities (from 49 kWh to 77 kWh) to be adapted as required, offering flexibility and upgrade options.

The SolidCore battery is the first semi-solid battery to be mass-produced. It uses predominantly solid electrolytes (around 95%), which create a more stable structure within each cell.

This design offers several advantages: increased range and faster charging for electric vehicles, better performance in cold weather (immediate start-up without preheating), and more refined energy distribution.

The SolidCore also improves safety, with an internal protective barrier that reduces the risks associated with traditional batteries and extends their lifespan.

Lithium iron phosphate (LFP) batteries are characterised by excellent thermal safety and high chemical stability, which reduces the risk of overheating or fire compared to other lithium-ion chemistries. They also offer a longer service life and a higher number of charge-discharge cycles, resulting in greater battery longevity and better performance over time.

LFP chemistry uses more abundant and less expensive materials, without rare cobalt or nickel, which can help to reduce the cost of the vehicle.

Finally, although its energy density is slightly lower, it allows for frequent recharging without rapid degradation, making it ideal for everyday and urban use.

NMC (Nickel Manganese Cobalt) chemistry offers high energy density, which means more energy stored per unit of weight, and therefore greater range compared to lighter LFP batteries.

It generally delivers better performance in cold conditions, with a more stable usable capacity as temperatures drop.

This chemistry also allows for faster and more efficient charging due to its ability to handle higher currents.

Finally, although it is slightly more expensive and has a lower cycle life than LFP, NMC remains an excellent compromise between range and performance, particularly suited to vehicles seeking to maximise range without significantly increasing weight

Scheduled for launch in Europe from late 2026, the SolidCore technology is designed to cope with varied climates and local requirements, whilst offering a more reliable and high-performance EV experience
