The genesis for a flagship Cadillac sedan has been traced back to concept vehicles including
486-694: A line as "all-wheel drive" as early as the late 1930s. This distinction in terminology is not generally used outside North America. In the context of hybrid and electric vehicles , the North American designation of 'all-wheel-drive' may differ. In some hybrid vehicles, the combustion engine is only mechanically connected to the front wheels, while the rear wheels are powered independently by an electric motor; this may be marketed as eAWD . Furthermore, many electric vehicles have individual, unconnected motors powering each axle, or even each individual wheel, also without any center differential. When tire grip
540-670: A maximum loaded weight of 3,000 pounds (1,400 kg). The concept of battery electric vehicles is to use charged batteries on board vehicles for propulsion. Battery electric cars are becoming more and more attractive with the higher oil prices and the advancement of new battery technology ( lithium-ion ) that have higher power and energy density (i.e., greater possible acceleration and more range with fewer batteries). Compared to older battery types such as lead-acid batteries. Lithium-ion batteries for example now have an energy density of 0.9–2.63 MJ/L whereas lead-acid batteries had an energy density of 0.36 MJ/L (so 2.5 to 7.3x higher). There

810-407: Is good during road driving, a differential is used between the axles to avoid driveline windup . This is not required off-road, as the limited grip allows the tires to slip. All-wheel drive vehicles designed for extensive off-road use may not have such a differential, and so they suffer from wind-up when used on-road. Selectable 4WD also avoids this problem and requires only a simple dog clutch in
864-425: Is needed. This DC power is supplied by the battery pack, and the controller regulates the power to the motor, supplying either variable pulse width DC or variable frequency variable amplitude AC, depending on the motor type. The controller also handles regenerative braking , whereby electrical power is gathered as the vehicle slows down and this power recharges the battery. In addition to power and motor management,
