A war of numbers has broken out between Ford and Toyota over the American carmaker's claim that the Ford Focus is the best-selling car in the world over the first half of 2012, writes Brian Byrne.
Ford made the claim after Focus sales reached 522,821 units to end of June, apparently toppling Toyota's Corolla from its long-standing global top place.
But Toyota countered immediately with a retort that the figures didn't take into account Corolla derivatives, such as the hatchback which was renamed Auris in the European market some years ago.
Toyota puts its unit sales globally of the model and derivatives at 603,840.
