Toyota Corolla (E30). The Corolla E30/E50 was the third generation of cars sold by Toyota under the Corolla nameplate.  It was built from August 1974 to July 1981 and marked Toyota's greatest growth in the United States in the wake of the fuel crisis. In addition to its sister model, the Sprinter, there was a redesigned-body version built by Toyota affiliate Daihatsu, called the Daihatsu Charmant. While there were certain fourth-generation models with a longer model life, this generation, when considered as a whole, was the longest-lived one, possibly due to the worldwide recession in the 1970s. A large range of cars was built using this chassis, including Corollas, Sprinters, Daihatsu, and the sporty Levin and Trueno models with the DOHC motor, with a fuel injection upgrade added to Japanese Levin models in January 1977.

Even though the E30 and E50 series were replaced by the E70 series in August 1979 in most markets, the original E30 series and the facelifted E50 series both continued to be produced until July 1981.

Design
The 3K engine was used in certain markets and later the 4K, while most Japanese and American models had the bigger 2T engine. A "Toyoglide" 2/3-speed automatic transmission was added as well as a four-speed (K40/T40) and five-speed (K50/T50) manual transmission, driving to the rear wheels. A three-door "liftback" (E50) and sports coupé (E51) was added in 1976. The E40 and E60 series were assigned to the Sprinter variants. In 1975, Toyota introduced the TTC-L (Toyota Total Clean-Lean Burn) on the 12T engine only, using a lean burn implementation.
in 1976, Toyota introduced the TTC-C (Toyota total clean-Catalyst) on the 3K-U engine, using single bed catalytic converter and lambda close-loop oxygen sensor with a supercharger smog pump.

This generation offered as standard equipment a new windshield wiper and headlight switch installation, operated by levers attached to the steering column.

North America
Introduced to North America in late 1974 for the 1975 model year, the base model cost , but only the Deluxe model had features comparable to the contemporary pack listed at . In 1975, for the 1976 model year, the Corolla received a minor facelift, including a revised grille and new hood with a raised centre section.

The E30 series 2T-C engines outmatched the rival Datsun B210's engine output.

Reception
Road & Track was critical of the 1975 Corolla, calling it "large and heavy" and "expensive" compared to the Honda Civic and Datsun B210. They also criticized the "relatively crude rear suspension", lack of interior space, and poor fuel economy when compared to the VW Rabbit.

Emissions became a problem further into the 1970s (especially with the 3K engine), which became popular because of its low fuel consumption. Its replacement, the 4K engine, came with Toyota TTC emissions equipment but only produced , despite a greater 1,290 cc displacement.

Europe

In Europe, the third generation Corolla was offered in the same body styles as in the US. All the sedans and wagons, along with the Hardtop coupé, were only offered with the 1.2-litre 3K, while the Liftback occasionally had the bigger 2T engine. The preceding 20-series Corolla continued to be available for as much as two years as a cheaper alternative, only with the two-door sedan body. A small facelift for the 1977 model year saw a redesigned dashboard and additional trim colours for the interior, and a new grille with small twin horizontal steel beams across it. For the 1979 model year, the last year of the E30 in Europe, the sedan's exterior trim was redesigned for the Deluxe model option with new tail lights (without the plastic chromed surrounds) and another new grille.

Australia 
The Corolla was manufactured in Australia at AMI-Toyota's Port Melbourne production facility. It was a popular car on the Australian market and most body styles available elsewhere were utilized. All variants originally came with Toyota's 1166 cc 3K-C engine, which was replaced by the 1290 cc 4K-C engine for the update released in November 1978.

Originally released in the SE trim, a luxury CS model was later released in February 1976. The CS featured carpeting, a clock, and reclining cloth seats. From July 1976, government regulated anti-pollution rules resulted in a loss of power for the further curtailed the 1166 cc 3K-C engine.

The first facelifted version of the Corolla in Australia was released in November 1978. Among the changes were a new grille and dashboard, along with revised interior trim. The previous 3K-C engine was superseded by the locally built 4K-C. At the same time, an entry-level SE version of the wagon was made available, with a range-topping XX coupé released in October 1979.

Due to the expenditure of manufacturing of the car in Australia, the production continued for several years after it was replaced by the next generation model everywhere else, although the TE72 Corolla Liftback was sold alongside as the Toyota T-18. A second facelift was released in July 1980, giving the car a new squared-off grille and rectangular headlamps, along with different tail lights on both sedan and hardtop; however it could not conceal the car's dated styling. This facelift coincided with minor interior trim changes, new seats, revised suspension settings, and a five-speed manual option. Production continued until July 1981, when the already aged fourth-generation E70 range replaced it.
