The LH platform was based on the American Motors-developed and Renault-derived Eagle Premier. According to Bob Lutz, "he Premier had an excellent chassis and drove so damned well that it served as a benchmark for the LH ... the spiritual father, the genetic antecedent of the LH is the Premier." Like the Premier, the LH-cars featured a longitudinally-mounted engine with a front-wheel drive drivetrain, unusual in most U.S. front-wheel drive cars, but a hallmark of Renault's designs. This arrangement meant that the design team had to use a chain to connect the automatic transmission with the front differential, a design reminiscent of the original Oldsmobile Toronado though subject to greater wear and noise.
