The increase was achieved by a mixture of a redesigned intake manifold with "D"-shaped intake runners and an increase in compression ratio to: 9.2:1[3]. Another notable change in the 5-speeds was the switch to a 4.30:1 gear ratio in the rear differential. All automatic Supra's retained the previous years power numbers, but the rear gear ratio was changed to a 4.10:1.

The most notable exterior change was the switch to wraparound front turn signals. Also on the outside the tail-lights were redesigned and the hatch received a billboard "SUPRA" sticker instead of the smaller sticker, which was previously positioned on the right. The rear hatch and bumper was changed and received the same color as the rest of the car (instead of the black of previous years). The door handles were also switched around, opening by pulling up instead of sideways. This year Toyota also decided to offer two-tone paint schemes on both the P-Type and L-Type.

Some interior controls such as the steering wheel, cruise control, and door lock switch were redesigned. Toyota encompassed a 130 mph (210 km/h) speedometer instead of the traditional 85 mph (137 km/h) one and the automatic climate control display was also changed. The previous year's cassette/equalizer stereo option was now made a standard feature.
