Weak auto sales figures for November look set to prolong the incentives war that has raged for months between America’s big three carmakers.

Sales were down 12% last month compared with November 2001 according to J D Power & Associates, though the slide was far less severe than October’s plunge of almost 25%. The leading trio – General Motors, Ford Motor Company and DaimlerChrysler – saw their share of the market fall from 65% and 62%.

The data are expected to prompt a new round of incentives. Indeed, GM, whose share fell to 25.2%, quickly unveiled new four-year and five-year interest-free financing deals on thirteen sports-utility vehicles, plus an extra $1000 (€993; £635) rebate on several car and truck models.
