AWD IS CONSTANTLY ON

COMPUTERS DETERMINE HOW MUCH POWER TO GENERATE ON EACH WHEEL

SENSORS MONITOR TRACTION, SPEED, AND OTHER DATA POINTS HUNDREDS OF TIMES A SECOND

4WD SYSTEMS ARE TYPICALLY USED BY OFF-ROAD VEHICLES

POWER GOES FROM THE TRANSMISSION TO A TRANSFER CASE WHERE IT IS DIVIDED BETWEEN FRONT AND REAR AXELS

ALL WHEELS are moving at the SAME SPEED

DRIVING UNDER NORMAL CONDITIONS IS MORE DIFFICULT

AWD VEHICLES DON’T PERFORM ASWELL IN EXTREME OFFROAD CONDITIONS

4WD VEHICLES CAN BE THE BEST VEHICLES FORSNOW COVERED ROADS

THE ABILITY TO OPERATE IN 2WD BOOSTS FUEL ECONOMY OF 4WD VEHICLESBOOSTS FUEL ECONOMY
