On 21 October 1997 the new Mercedes A-Class tipped over in a swerving test by a Swedish car magazine. Daimler-Benz stopped deliveries at once. It resumed them in February 1998, with electronic stability control fitted as standard, and it retrofitted the cars already sold. According to a report by the news agency dpa, fitting stability control as standard cost about 100 million marks a year. The reputation of the A-Class was damaged at first. The campaign that followed quoted the tennis player Boris Becker: Stark ist, wer keine Fehler macht. Stärker, wer aus seinen Fehlern lernt. (Strong is the one who makes no mistakes. Stronger is the one who learns from his mistakes.) Stability control later became standard in all Mercedes models.
