rpm, and featured Subaru Exhaust Emissions Control (SEEC). The car also received a minor facelift (with a "frowny" rather than the smiling grille seen on the turquoise four-door in the infobox being the most obvious difference) and a new chassis code: K22. Front disc brakes were also introduced as an option at the same time. The four-stroke Rex could reach a top speed of . The three-door, two-seater "Van" (K42) arrived in February of the next year, when a five-speed version (Custom5) was also added. The Van's engine was in a lesser state of tune and produces . In September 1974, along with a minor facelift consisting of a new grille and bumpers adjusted to allow for the fitment of larger license plates, a "Wagon" version (K26) appeared. This received four permanent seats, but was no longer registerable as a commercial vehicle and had a considerably lower max load. At the same time, a "Super L" version of the Van was added. The Wagon also received a lower tuned four-stroke engine, with at 7500 rpm; but torque increased somewhat to at 5700 rpm. In April 1975 the Van received a higher roof and became a four-seater. This was necessitated by Japanese commercial vehicle regulation which require the floor to be completely flat when the rear seat is folded. Because the Rex's engine was mounted in the rear, the cargo floor was rather high, meaning that more head room would be required before a seat could be installed. The Wagon continued in production until the SEEC-T version was introduced in December, but it lost most of its market with the availability of a four-seater Van. 28 PS became the power output of all versions of the Rex for model year 1976 after the SEEC-T (Subaru Exhaust Emission Control - Thermal and Thermodynamic) emissions control system was introduced in December 1975. Torque was down to at 6000 rpm. The equipment levels were also reshuffled, with the B-type replacing the Standard and then rising from the A via the AG and A to the AG on top. The A and AG versions received disc brakes in front, but the five-speed was no longer available. 550 cc era In response to new regulations for Kei cars introduced for 1976, Subaru introduced the larger-engined Rex 5 in May of that year. It retained the earlier bodywork (albeit broadened by 10 cm and with a lengthened
