Verdict

Buy with care

SUV électrique compact commercialisé en France depuis mai 2025, classé 5 étoiles à l'Euro NCAP, en 49 kWh (340 km WLTP) ou 64 kWh (jusqu'à 480 km). Un rappel de juillet 2026 vise les exemplaires produits de janvier 2025 à janvier 2026 (risque d'incendie du ventilateur de radiateur par grand froid) : exigez la preuve de la mise à jour logicielle. Le recul est faible, les retours publiés manquent.

Importing this model

Prices abroad

Not enough listings collected yet in Germany, Belgium, Spain, Italy or the United Kingdom for this model.

You are importing the car to:

Import penalty (malus) in France

  • The CO₂ malus follows the scale of the year the vehicle was first registered, in France or abroad (WLTP or NEDC scale depending on its registration certificate).
  • For an imported used car, it is reduced by a flat-rate discount based on its age in months (scheme in force since 1 March 2025). The weight malus also applies on first registration in France.
  • The malus is zero for a car more than fifteen years old or first registered before 1 January 2015.

Source: BOFiP (French tax doctrine), CO₂ and weight malus · CO2 malus and weight malus: imported used car in France

Check an imported car's history

HistoVec only covers the vehicle's life in France. For a car coming from abroad, a VIN-based report helps spot inconsistent mileage or a reported accident.

Known faults

Recent model: not enough hindsight yet (years, mileage) for faults to be publicly documented, so reliability is not rated. This is no guarantee: have the car checked all the more carefully before buying.

Manufacturer recalls

Manufacturer recall campaign, fixed free of charge at a dealer:

  • Ventilateur de radiateur gelé : risque d'incendie (rappel 2026) (S5 EV 49 kWh 170 ch, S5 EV 64 kWh 231 ch)

See the official list on RappelConso (new tab) (French government recall site: category “Automobiles et moyens de déplacement”, search “MG S5 EV”). A dealer for the brand can also check, using the vehicle identification number (VIN), that recalls have been carried out.

  • Maintenance: budget of a closely related model.
  • Maintenance: published servicing price plus an estimated allowance for tyres and brakes.
  • Depreciation estimated at 12% of the median price a year, as no year-by-year valuation is usable.
Calculation details (12,000 km a year)
Electricity€37

S5 EV 49 kWh 170 ch version: combined consumption of 16.6 kWh/100 km, increased by 15% for real-world driving, at 0.194 €/kWh, for 1,000 km a month.

Inspection checklist

Things to check

  • Faire vérifier avec le numéro de série que la mise à jour du rappel du ventilateur de radiateur (campagne KBA 16617R) a été faite.
  • Identifier la batterie : 49 kWh LFP (340 km WLTP) ou 64 kWh NMC (480 km), la charge rapide diffère (120 ou 139 kW).
  • Demander l'état de santé de la batterie et la date de fin de la garantie constructeur (7 ans ou 150 000 km annoncés).
  • Tester le chauffage et le fonctionnement du ventilateur par temps froid.
  • Essayer l'écran tactile et les aides à la conduite lors de l'essai.

Questions to ask the seller

  • Le rappel du ventilateur de radiateur (mise à jour IMCU) a-t-il été effectué ? Avez-vous l'attestation ?
  • Quelle version est-ce (49 kWh ou 64 kWh) et quelle autonomie affiche-t-elle en charge complète ?
  • Le véhicule a-t-il subi d'autres mises à jour logicielles ou interventions sous garantie ?

Test-drive tip: read the fault codes

A warning light that is off proves nothing: a fault may have been cleared just before the viewing. A Bluetooth OBD2 scanner, plugged in under the steering wheel and read on your phone, shows stored codes and whether all emissions readiness tests have run since the last reset.

Before you buy: check and equip

Check the history

Parts and maintenance

Compare prices of parts for the MG S5 EV I (timing, brakes, filters) to estimate the repairs to plan for.

Insure the car

Insurance prices vary widely from one model to another: get a quote before signing.
