The Premier inspired many of the LH platform’s design features. François Castaing, formerly AMC's Vice President of product engineering and development, became Chrysler's Vice President of vehicle engineering in 1988, and as a result, the Premier was the starting point for Chrysler's new LH sedans. Although the cab forward styling was quite different, the engines in the LH cars were mounted longitudinally, like the Premier. This was "a hallmark of Renault's front-wheel-drive designs" and unlike any other car built by Chrysler to that time. The LH platform's dedicated transmission, the A606, was also quite similar in design to the electronically controlled automatic featured in four-cylinder Premiers. The Premier's body shell was used for LH prototype development mules, under which the LH drivetrain was tested.
