Scion Brand Mulls 4th Car Model

Development of a fourth model for Scion could begin as early as next year, says Brian Bolain, national sales manager for Toyota Motor Corp.'s start-up youth brand.

But Toyota won't expand the lineup until after the launch of the second-generation Scion xB, due to appear in 2007.

Bolain declares a Scion truck or SUV is not a possibility, but some other type of vehicle — such as a station wagon — could work for future lineup expansion.
