The prized $1.6 billion car factory awarded to Alabama by Toyota Motor Corp. and Mazda Motor Corp. could be an even bigger win than expected, as the site's size leaves plenty of room for future expansions.

The 2,500-acre (1,000-hecatre) Huntsville location announced Wednesday is more than twice as big as the 1,100 acres the partners targeted initially, according to Bob Carter, Toyota's sales chief for North America.

"We always like to have plans and options for the future," Carter said, when asked if the bigger parcel is intended to accommodate expansions. He said the company has no additional announcements to make at this time.
