MotorFiable

The most reliable saloons

Ranked by the MotorFiable Score of the whole car, out of 10: half comes from its engines and the other half from the rest of the car (gearbox, suspension, brakes, electronics…). Only saloons with solid evidence are included: at least three sources and five documented faults, each backed by its sources.

Of the 95 saloons with solid evidence, the one with the highest score is the Audi A5 II (7.6/10), followed by the Alfa Romeo 166 (7.2) and the Volkswagen Arteon (7.1). The one with the lowest score is the Citroën C5 X (3.6/10), mainly because of oil-bath timing belt degradation.

The least reliable saloons

The three with the lowest scores and the fault that weighs most in each.

  1. Citroën C5 X · 3.6/10Oil-bath timing belt degradation (1.2 PureTech engine)
  2. Jaguar XF X260 · 3.6/10Timing chain stretch (2.0 Ingenium diésel engine)
  3. Peugeot 508 II · 4.3/10Oil-bath timing belt degradation (1.2 PureTech engine)

How it is calculated

The score combines the risk index of its engines and that of the rest of the car, calculated from the most serious documented faults (severity times frequency). Faults that the manufacturer fixes free of charge under a recall carry less weight. A high score does not guarantee that a particular car will not fail: it means we have found fewer serious, frequent documented faults. More recent models have been on the road for fewer years and may have fewer documented faults: preferably compare cars from the same period. Full methodology
