BMW is expected to report its third-quarter automotive operating margin rose to 7.9% after posting a loss in its core business a year earlier, a Reuters poll showed.

Quarterly earnings before interest and tax (EBIT) at its auto business should surge to EUR1.01bn (US$1.40bn) on revenue of EUR12.69bn, according to the average estimate of 17 banks and brokerages surveyed by the news agency.

Daimler’s Mercedes posted a very strong third-quarter EBIT margin of 9.5% while Bavarian luxury rival Audi managed an 11.2% operating return on revenue – a level so high analysts questioned whether this could be sustained in the future.
