Navistar Inc. said it has updated and re-designed its online truck configuration tool to allow customers to virtually design several models.

The online tool allows users to view different configurations of International, ProStar, DuraStar and TerraStar models.

"We know that an increasing number of customers in the commercial truck industry are researching their product wants, needs and desires online before visiting a dealership," Michael Cerilli, vice president of marketing at Navistar, said in a statement.

Users start by selecting their cab type, mirrors, aerodynamic package and other exterior features. Options for various powertrain configurations are available as well as engine, transmission and axle options.

"It's all about empowering the user to spec' their desired truck with the click of a mouse. The more we can provide useful tools to aid in their purchase process, the more likely we are to earn their business," said Cerilli.
