Germany’s dominant and influential automotive magazine Auto Motor und Sport initiated long term reliability tests way back in 1962, when it subjected a VW to a 15,000 km test. This was at a time when pretty much no one was subjecting cars to extended real-life evaluations, certainly in Europe. The length of the long term test kept increasing; in 1965 a NSU Prinz survived the first 50,000 km test, and a 1974 VW 1302 did quite well (for the times) in the first 100,000 km (61,000 miles) test. The worst ever was a 1978 Citroen CX 2400 that spent 65 days in the shop.
AMS subjects numerous cars per year to the 100k test, and no car had ever aced it (zero defects). That is, until now, when the Toyota Auris Hybrid (Corolla-based with Prius drive train) finished its two-year regime without any defects (beyond normal wear items). Well, technically, a light bulb burned out at 98,805 km, but that still gives it the best results ever, and AMS‘ title of “Null Fehler“.
