Along with the Plymouth Voyager and Town and Country, the Dodge Caravan was the most profitable product line for Chrysler in the early late '80s and early '90s.  Minivans were the new craze and they were popping up all over the country.

Like the 1989 model, the 1990 Dodge Caravan offered the turbo 2.5-liter, 150-horsepower engine which wasn't very popular with the soccer moms and suburbanites that were the minivan's target market, but was eagerly sought after by collectors and engine tweakers.   

New for 1990 is the 3.3-liter V6 150-horsepower automatic, but it came with the "Ultradrive" 4-speed automatic transmission, which was not well made and not very reliable.  The 3.0 V6 and the turbocharged 2.5-liter, 4-cylinder engines still remained an option for this year, but only on the smaller wheelbase models.  The 2.5-liter, 100-horsepower was still standard.

1990 is the last year for the first generation of the hugely successful Chrysler minivans, and the Dodge Caravan would get a makeover for its second incarnation.
