The HVY Biff is a large multipurpose truck featured in Grand Theft Auto IV, Grand Theft Auto V and Grand Theft Auto Online.


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. 

The Biff also has minor resemblence to mid-2000 models of the Freightliner 114SD, particularly in the headlight and grille areas.

In Grand Theft Auto V, the Biff has a green dump bed with a recycle logo on it, and the large exhaust are now changed into a straight exhaust. Other than this, the Biff's appearance has not changed very much since its last iteration in GTA IV and its episodes. The Biff is also no longer the only dump truck in the game, for there are two other dump trucks: the Tipper and the Rubble.  



Due to its size and weight, the Biff can only reach a top speed of 121mph. 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 driven 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.


Returning into GTA V, the Biff is now much slower, both acceleration and top speeds are poor. Its durability it much better however, and can take many head-on crashes for the truck to even start to burst into smoke. Its turning circle is much bigger than before, and can take up to 5 points to turn around in a basic 2 lane street. Its heavy weight results in all of these weaknesses effectively slower. The engine model appears to be a double-overhead camshaft Inline 4, in a front engine, rear wheel drive layout.
