Reflecting new Kei car rules, in July 1976 the length of the Hatch was extended to 3190 mm (wheelbase to 2100 mm), all ahead of the firewall. The new front and new large bumpers made what was an already odd-looking car even stranger. Now the Suzuki Fronte Hatch 55 (or 550), it received the three-cylinder 539 cc LJ50 engine, which was a de-smogged L50 engine with an extra cylinder tacked on: it was also known as the T5A/T5B in other applications. The new model code was SH10. The inside remained nearly unchanged and the only differences at the rear was a new, larger bumper, and the change to a single strut for the rear gate for increased access. Power remained 25 PS as for late model 360 Hatches, but torque was up considerably. The lineup was again restricted to B, D, and T models, with the T receiving chromed rather than painted bumpers.
