A 150-horsepower 2.4-liter four-cylinder is standard on the base Caravan, but few are equipped with this engine, which struggles to propel a 3,600-pound vehicle. Most base models come with a 150-horsepower 3.0-liter V-6, which provides adequate acceleration. Grand Caravans come with a 3.3-liter V-6 that generates 158 horsepower or a 3.8-liter V-6 that has 180 horsepower. All engines come with automatic transmission. Standard-length models have front-wheel drive, and extended models are available with either front-wheel drive or permanently engaged all-wheel drive.
