The second generation of the Chrysler minivan started with the 1991 Dodge Caravan. Although still on top, there was now more competition out there, so Chrysler revamped the interior and exterior of the Caravan, largely based on customer comments. First, they dropped the turbocharged engine. The 2.5-liter 4-cylinder remained standard, with optional 3.0 V6 and 3.3 V6 (with the oft-criticized Ultradrive) for more horsepower. A new ES trim was added. Interior additions include bucket seats in the first two rows, a redesigned dashboard, and more cupholders. The 1991 Caravan was also the first minivan to feature child safety locks, four-wheel anti-lock brakes, driver's side airbags, and finally AWD. Exterior additions include more glass for greater visibility, particularly in the rear, and a lower nose. Although still tops in customer satisfaction, many owners complain about the paint peeling off and the amount of repairs that need to be done. Also, they have a tendency to leak oil.
