This drivetrain configuration, commonly found in earlier generations of the Toyota 4Runner sport utility vehicle, delivers power to only two wheels, typically the rear. This setup often provides advantages in fuel efficiency and a lower purchase price compared to four-wheel drive variants. A typical example would be a first or second-generation 4Runner equipped with a rear-wheel-drive system, selectable via a transfer case lever or button.
Historically, this configuration was a standard option in many SUVs, offering a balance between on-road performance and affordability. The reduced mechanical complexity compared to four-wheel drive systems can translate to lower maintenance costs and increased reliability. While not suitable for serious off-roading, this drivetrain performs admirably in typical on-road driving conditions, including rain and light snow.
