Dodge initially offered three different engines in the Caravan. The base engine was a Chrysler 2.5-liter 4-cylinder that made 100 horsepower. This engine also was used in several other Chrysler products like the LeBaron, Spirit, Dynasty, and Shadow. It was offered only with a 3-speed automatic transmission, but 5-speed manual supplanted the automatic in 1992. The first step up was a 3.0-liter V6 engine that made 142 horsepower. This engine was available with either a 3- or 4-speed automatic. The 3.0-liter V6 is a Mitsubishi-designed engine with a single-overhead camshaft. Also optional was a 3.3-liter V6 that initially made 150 horsepower but was upgraded in 1994 to 162 horsepower. In 1994, Chrysler added a 3.8-liter V6 to the lineup. This engine also made 162 horsepower, but had significantly more torque (pulling power) than the 3.3-liter V6. Both the 3.3- and 3.8-liter V6 engines come only with a 4-speed automatic transmission, have overhead valves, and were built by Chrysler. The AWD system was only available on models with the 3.3-liter engine. The system is always engaged, but normally sends power to only the front wheels. If wheel slip is detected, power is redirected to the wheels with the most traction. Unlike most sport-utility vehicles, there is no low range on the Caravan AWD system.
