At a guess- customer convenience. Comparing say a BMW335 and a Nissan Maxima (two similar but randomly chosen vehicles) the BMW holds 6.5L and a change is needed every 24months/25,000km. For the Maxima(USA Model) it holds 4.2quarts(3.97L) and a change is needed every 6months or 7500 miles(12070km).

So as well as the extra cooling provided by the extra oil, the BMW needs around 1.5L less if oil is changed according to distance, or a whopping 10L less if changed according to elapsed time. Factor in the savings in labour costs as well, from fewer changes, and the German car is well ahead.
