Companies in the UK tend to be quite polite in their advertising - they stick to talking about their own product and steer clear of naming a competitor they feel they outperform.
Americans aren't so shy and retiring. This Audi ad from across the pond stops short of dancing around and singing "Audis rule, BMWs drool", but only just.
The reason for the gloating, so the ad says, is Audi's run of three straight victories over BMW in comparison tests in American car mag Car and Driver. We'd love it if there was something similar over here - perhaps Peugeot could start bating Renault over the 3008's recent What Car? Car of the Year victory.
