- Six-wheel drive (6WD or 6×6) is an all-wheel drive drivetrain configuration of three axles with at least two wheels on each axle capable of being driven simultaneously by the vehicle's engine. Unlike four-wheel drive drivetrains, the configuration is largely confined to heavy-duty off-road and military vehicles, such as all-terrain vehicles, armored vehicles, and prime movers. When such a vehicle only has six wheels by definition all are driven. When it has ten – with two pairs of ganged "dual" wheels on each rear axle as on a GMC CCKW – all are also driven but the 6×6 designation remains. For most military applications where traction/mobility are considered more important than payload capability, single wheels on each axle (often referred to as super singles) are the norm. Heavy hauler and ballast tractor 6×6s have had a long history as prime movers both in the military (as tank transports and artillery tractors), and commercially in logging and heavy equipment hauling both on- and off-road. Most six-wheel drive vehicles have a forward axle and two at the rear (with only the front pair steering), or three evenly spaced in varying steering configurations. Depending on the vehicle's role, the number of wheels varies between six (in three pairs) and ten (with two in the front and two dual axles with four wheels apiece in the rear). Drive may be limited to the rear two axles for on-road use. (en)
- 六輪駆動（ろくりんくどう）または6WDとは、車両の駆動方法の一種である。通常は自動車の6輪のタイヤを駆動輪として使う駆動方式を指す。 (ja)
- 六輪驅動（Six-wheel drive）指傳動系統把引擎的動力同時傳送到六個車輪，這類設計主要在重型卡車、農用工具、越野車和軍用車輛上使用 。若汽車有六個車輪，並以全輪驅動，則被稱為「6x6」。 有些重型車輛的後軸會採用雙輪胎設計，也會被視作一個輪胎（即是6x6），因此實際的輪胎總數有6到10個。部分六輪驅動車輛允當司機在鋪裝路面行駛時改以四輪驅動運作（6x4），以減少汽車零件的損耗。 (zh)
