In the North American market, the Celica Supra was available in two distinct models. There was the "Performance Type" (P-type) and the "Luxury Type" (L-type). While being mechanically identical, they were differentiated by the available options; tire size, wheel size, and body trim. The P-type had fiberglass fender flares over the wheel wells, while the L-type did not. The P-type was also standard with the more sporty eight-way adjustable seats. The P-type did not get the option of a leather interior until 1983. All editions of the P-type had the same 14x7-inch aluminum alloy wheels and throughout the years the L-type had -inch wheels until 1985 when they were changed to a P-type styled 15x6. The L-type also had the option of a digital dash with trip computer ; some Canadian models had this option as well as a few rare instances of American models. The digital dash featured a digital tachometer, digital speedometer, and electronic fuel level and coolant level gauges. The trip computer could calculate and display various things such as fuel economy in miles-per-gallon, estimated time of arrival (ETA), and distance remaining to destination. Excluding the 1982 model, all P-types were available with headlight washers as an option, but the L-types were never given such an option. Although gear ratios changed throughout the years, all P-types came standard with a limited slip differential .
