The Toyota T100 (not to be confused with RK100) was a full-size pickup truck introduced by Toyota in late 1992 as a 1993 model year vehicle.
As Toyota firmly established itself in the North American compact pickup truck market in the 1980s through 1990s, it seemed only logical that Toyota needed to capture part of the lucrative full-size pickup truck market. Rumored for many years before, the 1993 Toyota T100 boasted a full-size (8 ft) pickup bed but retained the engine and suspension setup of its smaller and older sibling, the compact Toyota Pickup Truck Although the T100 was a bit larger than the competitive mid-size Dodge Dakota and compact Ford Ranger pickup trucks of the time, it was still much smaller than full-size American pickup trucks of the time. This gave the T100 a unique position and opportunity within the truck ranks. Though economical, reliable and practical, in the grand scheme of things the unsuccessful T100 had not captured as much of the market as Toyota had hoped. Many critics maintainedthe T100 was still too small, despite being larger than both the Toyota Pickup Truck and the Toyota Tacoma compact trucks, for the full-size segment.
