Gear Ratio
GEAR RATIO
This is a numerical ratio of a series of gears in relation to each other, based on the number of turns of the input shaft, compared to turns of the output shaft. Gear ratios are determined by the number of teeth on each gear (and therefore the size of each gear).
Ground Clearance
GROUND CLEARANCE
Ground clearance is the measurement from the lowest-hanging point under a vehicle (usually a differential, part of the suspension or the exhaust system) towards the ground. A high ground clearance allows a vehicle to drive more easily off-road or through heavy snow without damaging the underbody.
Gross Vehicle Weight
GVW
Gross Vehicle Weight (GVW) is the total weight of a vehicle (with passengers, luggage, fuel, coolants and any options or accessories).
Gross Vehicle Weight Rating
GVWR
The maximum allowable total weight of the vehicle that may not be exceeded, as designated by the manufacturer. GVWR is identified on the manufacturer's certification label, which is usually located on the driver's door or door jam. GVWR is the combination of curb weight plus payload (including driver and fuel).
