Developed under chief Masaaki Ishiko from 1990 to 1995 under the project code 185T, in late 1995 (for the 1996 model year) a significant redesign of the 4Runner was introduced, with an all-new body shell on an all-new chassis. Though it shared many parts, including engine and transmission, with the new Tacoma, the body and chassis were unique for the first time. Despite moving upmarket with the rest of the mid-size SUV market, the new 4Runner differentiated itself by retaining the rugged off-road character its competitors were sacrificing for highway comfort.
