May – Fronte LC20 discontinued.

Reflecting new Kei car rules, in July 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 per late 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.
In June 1976 the Fronte 7-S was presented, model code SS10. As per the new regulations, it was 100 mm (3.9 in) wider than the LC20 series and had a larger engine of 443 cc. Wheelbase remained at 2,030 mm (79.9 in), while overall length grew to 3,190 mm (125.6 in) thanks to new bigger bumpers and a somewhat bulkier rear end. The more squared-off front end also allowed for a larger front luggage area. The T4A engine was still a three-cylinder two-stroke (simply a bored out version of the LC10), as Suzuki considered themselves experts at this configuration. The new Suzuki TC ("Two Catalyst") emissions system meant that it could meet the new emissions standards. The downside was that the new engine produced a mere 26 PS at 4500 rpm rather than the 32 PS of the 360 cc engine it replaced. The layout remained RR, with a four-speed manual transmission. "7-S" was meant to stand for Space, Safety, Sense, Save money, Silent, Stamina, and Suzuki TC.
The LJ50 engine was first introduced in September 1975 for export only, with 33 PS (24 kW). For the home market, it first appeared in June 1976 as the Jimny 55 and reflected the changing kei car rules and stricter emissions standards. The 539 cc (32.9 cu in) three-cylinder engine remained a two-stroke; while power was reduced to 26 PS (19 kW) more low-end torque was on offer. The 635 kg (1,400 lb) vehicle could now hit 60 mph (97 km/h), and the spare tire was relocated outside the rear door, allowing for a fourth seat.
In May 1976, the low production LJ51P long wheelbase pickup became available for some export markets.
