Grease Monkeys: Vehicle Guide (2002)

From Introduction:

The statistics and abilities of vehicles are given in the same format as a creature, with the following exceptions:

Type
All vehicles have the Construct (Vehicle) type. They have all the same abilities and qualities of standard constructs, except that they never have darkvision. Additionally, while vehicles do not take extra damage from critical hits, they can take component damage if a critical hit is scored.

Speed
Vehicles have two speeds listed – Cruising Speed and Maximum Speed. Any speed up to and including the vehicle’s cruising speed is counted as Cruising Speed for rules purposes, and any speed from cruising to maximum is similarly counted as Maximum Speed.
