Closely resembling a Kenworth T800, the Biff is a conventional cab truck used in construction and industries commonly encountered in industrial districts in the game. The Biff is available in different configurations in flat-bed form, or two different types of dump truck, with some being filled with gravel.
PerformanceDue to its size and weight, the Biff can only reach 121 mph. All variants tend to understeer badly when putting power on into a corner. Also the rear wheels have a very bad tendency of locking up under medium to heavy braking, telling us ABS is non existent. The Biff also shares the same engine sound as the Bus when driving with the 'in cab' view.
When driving around areas such as Star Junction and The Triangle, the Biff is easier to drive than the Flatbed, owing to the fact it has a more 'ergonomic' nose, this also improves driver visibility greatly.
