MG MG4 vs Renault Megane E-Tech

Side-by-Side Specs

Charging Speed

The MG MG4 has a peak DC charging speed of 142 kW, which is roughly 10% faster than the Renault Megane E-Tech at 129 kW. In practice, peak speed only tells part of the story. The charging curve, battery temperature, and state of charge all affect how quickly your car actually charges.

Both cars use 400V architecture, so their charging curves should follow similar patterns. The difference in peak speed comes down to battery chemistry, thermal management, and the onboard charger design.

For the 10-80% charge (the most common DC fast charging scenario), the MG MG4 finishes in about 25 minutes, which is 8 minutes quicker than the Renault Megane E-Tech at 33 minutes. On a road trip, that difference adds up over multiple stops.

Range and Efficiency

The Renault Megane E-Tech offers 380 km of real-world range, which is 20 km more than the MG MG4 at 360 km. These are real-world estimates, not WLTP numbers. Expect your actual range to vary with speed, weather, terrain, and driving style.

Efficiency matters more than battery size for daily driving costs. The Renault Megane E-Tech consumes 158 Wh/km, compared to 171 Wh/km for the MG MG4. That means the Renault Megane E-Tech uses less energy per kilometer, which translates to lower charging costs and fewer charging stops on longer drives.

A more efficient car does not always mean more range. Battery size plays a role too. The Renault Megane E-Tech has a 60 kWh useable battery , while the MG MG4 has 61.7 kWh.

Cold Weather Charging

Neither car includes a heat pump as standard, which means both will see more range loss in cold conditions compared to models that do.

Battery preconditioning is equally important for winter DC fast charging. When the battery is cold, charging speeds drop significantly. Both cars support preconditioning, which warms the battery before you arrive at a fast charger so you get closer to peak charging speed.

In cold conditions, expect 20-35% range loss compared to ideal weather. Cars with both a heat pump and preconditioning typically handle winter better overall.

Which One Should You Choose?

If fast charging speed is your priority, the MG MG4 has the edge with 142 kW peak DC and a 25-minute 10-80% time. For long road trips with multiple charging stops, that faster turnaround makes a real difference.

If you mostly charge at home or at work and care more about daily driving costs, the Renault Megane E-Tech is the more efficient choice at 158 Wh/km. Lower consumption means lower electricity bills over time.

For maximum range between charges, the Renault Megane E-Tech gives you 380 km of real-world range, which is 20 km more. Both are capable EVs. The best choice depends on how you charge and how far you drive.
