First appearing in 1987, Chrysler's Lamborghini Portofino was exhibited during the 1988 Chicago Auto Show. Portofino predicted the "cab-forward" styling that Chrysler would adopt in the 1990s, which did not include the scissors-style front and rear doors. The prototype was powered by an 225 horsepower aluminum eight-cylinder engine placed mid-ship and mated to a Lamborghini five-speed manual transmission.
