The Suburban for 1950 was accompanied by a four-door Special Deluxe wagon, the last of the "woodies", for those wanting something a little more traditional. There were two Plymouth wheelbases, with the Suburban riding on the shorter 111-inch (2,800 mm) platform (the Special Deluxe was 118.5 inches). Vinyl upholstery was used, as this was more hard-wearing for utilitarian use. Motive power was the Chrysler Corporation's smallest six, a 217.8 cid L-head that produced 97 bhp @ 3,800rpm. The Suburbans rode on 6.40x15 inch Goodyear tyres, though a 6.70x15 inch "Super Cushion" tyre option with higher gearing was offered, as was a high-clearance 18-inch (460 mm) wheel option. A "taxi package" was recommended to owners expecting to carry heavy loads, featuring heavy-duty chassis springs and shock absorbers, a 100amp/hr battery with a heat shield, and even heavier grade springs in seats and seat backs.
