This generation (apart from the wagon) got a new rear
coil spring five-link rear end with a
panhard rod, and the wheelbase was longer at . A new
3T engine was optional to some markets, while parts of the world retained the old
4K. The most notable
inline-four engine advancement came in 1979 and 1983, however, as Toyota began offering the
3A-U and
4A-C engines respectively. The aluminium head,
SOHC engines, although bulkier in size and weight than the
K and
T engines it was offered alongside, was a grand step up in performance. This would be the last generation of Corollas to use any
pushrod or
alloy cylinder head engines, as
Toyota made the decision to focus exclusively on
aluminium head,
OHC engine design from this point forward. This was the first generation to have power steering. In the US market, this was introduced in 1981 for the 1982 model year. Various facelifts were made during production. In 1979–1980, a four-round headlamp setup was used in most markets. A restyle for 1981 involved two rectangular headlamps. A more extensive facelift was given for 1982, involving a new sloping nose with wraparound headlights, remodeled taillights and new bumpers, which on some models were rubber moulded. From August 1983 (subsequent to the changeover to front-wheel drive for the rest of the range) the Corolla Van received a new 1.5-litre 5K-J engine as well as a light restyling, and also a roof raised by . The Wagon/Van underwent a final light facelift in August 1985, including an upgraded 1C-II engine for the diesels. It also received seats that could be folded nearly flat to make the car beddable, and continued in production until being replaced by the 90-series Corolla Van/Wagon in August 1987. ==Design==
