Mg Marvel R: Software Update R24 Extra Quality

Feature Spotlight: MG Marvel R Software Update R24

The R24 update represents a significant milestone for the MG Marvel R, particularly for European and UK markets. While over-the-air (OTA) updates are becoming standard for Tesla and Volkswagen, MG has utilized the R24 update to address some of the most critical feedback from early adopters, specifically regarding charging speeds and infotainment stability.

Here is a breakdown of the key features, improvements, and changes included in the R24 software version.

Pros

  • Smoother one-pedal driving.
  • YouTube capability while parked (great for charging stops).
  • Better ACC behaviour in traffic.
  • Reduced phantom drain on 12V battery.

4. Verification and troubleshooting

1. DC Fast Charging Performance Boost

The headline feature of the R24 update is the optimization of the DC fast-charging curve. mg marvel r software update r24

  • Improved Peak Power: Earlier software versions struggled to maintain high charging speeds, often dropping off too quickly as the battery charged. The R24 update optimizes the Battery Management System (BMS), allowing the vehicle to sustain higher kW charging rates for longer durations.
  • Cold Weather Charging: Users have reported better pre-conditioning logic. The update improves the ability to charge the battery from a cold state, reducing the time spent "warming up" the battery before peak charging speeds are reached.
  • 10% to 80% Target: While the hardware limit remains the same, the software optimization brings the real-world 10-80% charge time closer to the manufacturer's claimed 43 minutes (for the 77kWh battery), a noticeable improvement over previous firmware.

Method B – USB Update (Dealer or Advanced Users)

If OTA fails or isn’t offered:

  1. Request the R24 update file from an MG dealer (file size ~2–5 GB).
  2. Format a USB drive (FAT32, 16–32 GB).
  3. Copy update files to root directory (do not rename folders).
  4. Insert USB into the vehicle’s data USB port (usually the one with a computer icon).
  5. Go to Settings → System → System Update → Update via USB.
  6. Follow on-screen instructions. Do not remove USB until finished.

1. Refined User Interface (UI) Logic

One of the most noticeable changes in R24 is the smoothing of the infotainment system. Previous versions occasionally suffered from lag when switching between drive modes or navigating menus. R24 optimizes the GPU load, resulting in:

  • Faster screen transitions.
  • Reduced latency when inputting navigation destinations.
  • Smoother animations for the virtual instrument cluster.

Should You Install R24 Immediately?

For the vast majority of Marvel R owners, yes. The benefits far outweigh the minor inconveniences. However, if you are about to embark on a long road trip, consider delaying the installation until you return, as the 40-minute downtime and potential setting reset could be frustrating mid-journey.

If you are on a very old version (R17 or R19), you may need a dealer to perform a two-stage update (first to R21, then to R24) because the cryptographic signatures have changed. Check your current version in Settings > System > About.
