In 2014, Audi introduced the Q3 SUV at a base price of only $32,500. And BMW, with its 1-series, is another well-known example. Such cars, priced in the low $30,000s, compete more directly with products from broad-line manufacturers like Ford, General Motors, and Toyota. This suggests that members of a strategic group can overcome barriers and migrate to other groups that they find attractive if they are willing to commit time and resources.
