Toyota issues engine ultimatum

Toyota has been a Champ Car powerplant supplier since 1996 with the current 2.65-litre, turbocharged engines. But the Japanese marque says it will only supply 3.5-litre, normally aspirated V8 engines in 2003, the specification used by the rival IRL series.

CART is expected to make a decision on its new engine formula as early as next weekend at Houston, but Toyota's announcement will force it to adopt the IRL rules or face the future without it.

"Our timetable for business planning reaches a critical point, and we simply couldn't wait any longer - Toyota has made its decision," said J Davis Illingworth Jr, Toyota's senior vice president. "From a financial perspective, it is not prudent for Toyota to supply two different engine specs for US-based, open-wheel racing while also in the early stages of a Formula 1 programme internationally.

"As for future engine specs, we are certain CART will decide what is best for its shareholders and participants. If CART adopts the same engine specifications as the IRL, and it makes good business sense from both a financial and marketing standpoint, Toyota would consider participating in the series," he added.

Toyota has renewed its pledge to compete in next year's CART series. It is one of three current engine suppliers along with Honda and Ford.
