Unveiling the Fastest MG Electric Car: The MG4 XPower

The Crown Jewel of MG’s EV Lineup

The title of fastest MG electric car belongs to the MG4 XPower, a high-performance variant of the award-winning MG4 hatchback. Unveiled in 2023 and launched in key markets including the UK, Europe, and Australia, the XPower isn’t just a souped-up version of its sibling—it’s a ground-up performance machine designed to compete with premium EVs like the Volkswagen ID.3 GTX and Cupra Born VZ. With a dual-motor all-wheel-drive (AWD) system, a 64 kWh battery pack, and a host of track-focused upgrades, the MG4 XPower redefines what a sub-£40,000 EV can achieve.

What sets the XPower apart is its balance of performance and practicality. Unlike many high-performance EVs that sacrifice range and comfort for speed, the MG4 XPower delivers both. It maintains the spacious interior and 5-star Euro NCAP safety rating of the standard MG4 while adding performance hardware that transforms its character on the road. This duality is rare in the EV market and makes the XPower a compelling option for drivers who want weekend track thrills and weekday commuter efficiency.

Technical Specifications That Deliver

Under the skin, the MG4 XPower is powered by a dual-motor setup that delivers a combined 435 horsepower (320 kW) and 605 Nm (446 lb-ft) of torque. This is a massive leap from the standard MG4’s 170–204 hp range. Power is sent to all four wheels via an electronic torque vectoring system, allowing precise control during cornering and launch. The result? A 0-60 mph time of just 3.8 seconds, making it not only the fastest MG electric car but one of the quickest hot hatches in its class.

The battery is a 64 kWh lithium-ion pack (with a usable capacity of 62.5 kWh), offering a WLTP range of up to 239 miles (385 km). While this is slightly less than the standard MG4 Long Range (323 miles), the trade-off is justified by the performance gains. The XPower also features a 150 kW DC fast-charging capability, allowing drivers to go from 10% to 80% charge in just 30 minutes—perfect for long drives or track days.

Real-World Acceleration and Launch Performance

In real-world testing, the MG4 XPower’s acceleration is nothing short of exhilarating. The instant torque delivery from the dual motors means the car rockets forward the moment you press the accelerator. Unlike turbocharged internal combustion engines (ICE), there’s no lag—just seamless, linear power. Independent tests from Autocar and What Car? confirm the 3.8-second 0-60 mph claim, with some drivers achieving 3.7 seconds in optimal conditions (dry pavement, fully charged battery).

The launch control system is intuitive: simply press the “XPower” button on the center console, hold the brake, floor the accelerator, and release. The car manages wheel slip and torque distribution automatically, ensuring maximum grip and minimal drama. For drivers new to high-performance EVs, this makes the XPower surprisingly easy to drive fast—without the intimidation factor of manual launch tuning.

Performance Beyond the Numbers: Handling, Braking, and Dynamics

Track-Ready Chassis Tuning

Speed is nothing without control, and MG has gone to great lengths to ensure the XPower handles as well as it accelerates. The car sits on a revised version of the MSP (Modular Scalable Platform) architecture, with stiffer springs, adaptive dampers, and a lowered ride height (by 10 mm). The front suspension uses MacPherson struts, while the rear features a multi-link setup—ideal for managing the torque loads from the dual motors.

One of the standout features is the electronic torque vectoring system. During cornering, the system can send more torque to the outer rear wheel, effectively “pulling” the car through the turn. This reduces understeer and improves agility, especially on tight, winding roads. In track tests at the Millbrook Proving Ground, the XPower demonstrated exceptional mid-corner stability and predictable rotation—qualities usually reserved for premium German or Italian hot hatches.

Braking Performance and Regenerative Tuning

Stopping power is handled by upgraded 345 mm ventilated front discs with four-piston Brembo calipers (a first for an MG production car), and 330 mm rear discs. These provide fade-resistant braking under repeated hard stops—essential for spirited driving or track use. In a 60-0 mph panic stop test, the XPower achieved a distance of just 33.2 meters, placing it among the top 10% of hot hatches in its class.

Regenerative braking is customizable via three levels (Low, Medium, High), with the highest setting enabling near “one-pedal driving.” In “High” mode, the car can slow significantly when lifting off the accelerator, reducing reliance on the friction brakes. This not only improves efficiency but also helps preserve brake pads during long drives. For performance driving, we recommend switching to “Medium” to maintain better control during corner entry.

Driving Modes and Customization

The XPower comes with four driving modes: Eco, Comfort, Sport, and XPower. While Eco and Comfort optimize for efficiency and ride comfort, Sport and XPower unlock the car’s full potential. In Sport mode, throttle response is sharpened, steering weight increases, and the torque vectoring system becomes more aggressive. XPower mode goes further, activating a unique “track-inspired” calibration that maximizes responsiveness and allows slight rear-biased drift tendencies (within electronic safety limits).

Pro tip: For the best balance of performance and safety, use Sport mode on public roads and reserve XPower mode for private tracks or empty stretches where you can fully exploit the car’s capabilities without endangering others.

Battery, Charging, and Range: The Practical Side of Performance

64 kWh Battery: Power vs. Endurance

The 64 kWh battery in the MG4 XPower is a high-density lithium-ion unit with a nickel-manganese-cobalt (NMC) chemistry. This chemistry offers a strong balance between energy density, power output, and thermal stability—critical for sustained high-performance driving. Unlike some EVs that experience “battery derating” (reduced power output) after repeated hard launches, the XPower maintains consistent performance thanks to an advanced liquid cooling system.

However, the high power draw of the dual motors means range is more sensitive to driving style. In real-world mixed driving (city, highway, and spirited B-roads), expect a usable range of 200–220 miles (320–350 km). On the highway at 70 mph, this drops to around 180 miles due to aerodynamic drag and higher energy consumption. For comparison, the standard MG4 Long Range (77 kWh battery) achieves 300+ miles under similar conditions.

Charging Infrastructure and Real-World Tips

With a 150 kW DC fast-charging capability, the XPower can add 100 miles of range in just 15 minutes when connected to a high-power charger (e.g., Ionity, Gridserve). This makes long-distance travel feasible, though planning is key. Here are some practical tips:

• Use the MG Pilot app to locate and reserve fast chargers along your route.
• Charge to 80%, not 100% for faster top-up times and improved battery longevity.
• Precondition the battery while plugged in before fast charging—this reduces charging time by up to 20%.
• Avoid fast charging in extreme cold unless the battery is preconditioned; cold batteries charge slower and can suffer reduced capacity.

For home charging, a 7.4 kW wallbox (included with purchase in many markets) will fully charge the XPower in about 9 hours. Overnight charging is ideal for daily use, especially when combined with off-peak electricity tariffs.

Thermal Management and Longevity

The XPower’s battery is equipped with a liquid cooling and heating system that maintains optimal operating temperatures (15–35°C). This not only improves performance during hard driving but also extends battery life. MG claims the battery retains 80% capacity after 10 years or 150,000 miles, backed by an 8-year/100,000-mile warranty.

To maximize battery health:

• Limit DC fast charging to 1–2 times per week unless necessary.

<

• Store the car at 40–60% charge if unused for long periods.
• Use scheduled charging to avoid leaving the battery at 100% for extended durations.
