Toyota's First Sports Coupe
The Toyota Celica was born from a simple, powerful idea: build a car that looked like it belonged on a racing circuit and priced it so that ordinary people could afford it. In 1970, Toyota -- already one of the world's largest car manufacturers -- had no sports car in its lineup. The Celica changed that, and in doing so created one of Toyota's most beloved and longest-lived nameplates. The Celica name would endure for seven generations over 36 years, but it was the first two generations -- the A20 and A40 -- that established its character.
The early Celica was unashamedly inspired by the American pony car formula. The Ford Mustang had proved in 1964 that a compact, stylish coupe with a range of engines -- from economical to sporting -- could sell in enormous numbers. Toyota applied this formula to the Japanese and international market, scaling it down to suit smaller engines and tighter roads. The result was a car that was distinctly Japanese but universally appealing.
The Concept and Development
Toyota first showed the Celica concept at the 1970 Tokyo Motor Show, though the production car had been in development since 1967 under the direction of Toyota's Carina platform engineering team. The Celica shared its platform, floorpan, and many mechanical components with the Toyota Carina sedan -- a practical piece of parts-bin engineering that kept development costs manageable.
The styling was the work of Toyota's in-house design team, with the first-generation car showing clear Mustang influence in its long bonnet, short rear deck, and muscular proportions. The design was clean, balanced, and modern -- it avoided the excesses of some contemporary American designs while retaining their sense of excitement.
Toyota offered the Celica with a range of engines, from the frugal 1.4-litre T-series to the sporting 2.0-litre 18R-G twin-cam. This breadth of powertrain options was central to the strategy -- the base Celica brought customers into the showroom with its styling, while the twin-cam GT demonstrated Toyota's sporting credentials.
First Generation -- A20 Series (1970--1977)
The TA22 Coupe (1970)
The first-generation Celica launched in December 1970 in Japan as the TA22 (with the 2T engine). The coupe body was a two-door hardtop with a clean pillarless design, flowing fender lines, and a cabin set well back on the wheelbase -- all classic sports coupe proportions.
The initial engine range in Japan included:
- 2T (1.4L OHV): Economy model
- 2T-B (1.6L OHV): Mid-range
- 2T-G (1.6L DOHC): The twin-cam sporting engine, producing approximately 115 hp
The 2T-G was the enthusiast's choice from the beginning. The twin-cam head, with its hemispherical combustion chambers and twin side-draft carburettors, transformed the modest 1.6-litre engine into something genuinely exciting. It revved eagerly to 7,000 rpm and made a sound that was pure motorsport.
Australian Market Arrival
The Celica arrived in Australia as the RA23, powered by the 18R 2.0-litre single-cam engine. The 18R was the appropriate choice for the Australian market, where the larger engine provided better mid-range torque for Australian driving conditions. The twin-cam 18R-G was available on performance models and was the engine that defined the Celica experience for Australian enthusiasts.
The Celica was an immediate success in Australia. Toyota's dealer network was well-established, and the Celica offered something genuinely new: a proper sports coupe from a manufacturer known for reliability. The Holden Monaro and Ford Falcon GT were faster in a straight line, but the Celica was lighter, more agile, and more refined. It appealed to a different buyer -- someone who wanted sporting character without the crude masculinity of the local V8s.
The Australian-market designations were:
- RA23: First-gen coupe with 18R engine
- RA28: First-gen liftback with 18R engine
- Twin-cam models used the RA prefix with additional R-G engine designation
The Liftback Arrives (1973)
In 1973, Toyota introduced the Celica Liftback (RA28 in Australia), adding a fastback body style with a rear hatch. The liftback was a significant commercial success -- it offered the Celica's sporting character with vastly improved practicality. The rear cargo area, accessed through a full-width hatchback, made the Celica a genuine grand tourer.
The liftback also introduced a new design character. Where the coupe was crisp and angular, the liftback was more flowing and aerodynamic. Some enthusiasts preferred the coupe's purity; others found the liftback more distinctive. Both opinions are valid -- they are different interpretations of the same formula.
The Twin-Cam Legend
The 18R-G twin-cam engine is the heart of the Celica legend. Making approximately 110 horsepower from 2.0 litres might not sound impressive today, but in a car weighing around 1,000 kg, it was enough for genuine sports car performance. More importantly, the way the 18R-G delivered its power was special.
The twin-cam head breathed far better than the single-cam 18R. The power delivery was linear and progressive, building smoothly from idle to a 7,000+ rpm redline. The twin side-draft carburettors -- usually Mikuni-Solex or Aisin units -- provided precise fuel metering and a wonderful intake sound under full throttle. The engine felt alive in a way that the worthy but mundane single-cam did not.
The 18R-G was also used in other Toyota models, including the Corona Mark II and Crown, but it was in the Celica that it found its natural home. The combination of the responsive twin-cam engine, the lightweight coupe body, and the willing chassis created a driver's car that could compete with European rivals costing significantly more.
Second Generation -- A40/A50 Series (1977--1981)
Refinement, Not Revolution
The second-generation Celica, launched in 1977 as the A40 series (RA40 in Australia), was an evolution rather than a revolution. Toyota took the first-generation formula and refined it: more interior space, better NVH (noise, vibration, harshness), improved aerodynamics, and updated styling.
The A40 was larger than the A20 -- longer, wider, and slightly heavier. The styling moved away from the Mustang influence toward a more angular, European-influenced aesthetic. The coupe retained the pillarless hardtop design, while the liftback continued with its practical hatchback.
The engine range carried over from the first generation, with the 18R (single-cam) and 18R-G (twin-cam) remaining the primary options for the Australian market. The second-generation car's slightly heavier weight made the twin-cam even more desirable -- the single-cam 18R was adequate in the first-gen but felt stretched in the heavier A40.
The RA40 in Australia
The RA40 was another strong seller for Toyota in Australia. By the late 1970s, Toyota had established itself as a major force in the Australian market, and the Celica was a key part of the brand's image. The RA40 offered more refinement and comfort than the RA23/RA28 while retaining the sporting character that had made the Celica successful.
The Australian market received both coupe and liftback body styles. The twin-cam 18R-G was available as the GT specification, while the single-cam 18R powered the ST. The 5-speed manual gearbox was standard on most models, and the overall package was competitive with European rivals like the Opel Manta and the Alfa Romeo Alfetta GT -- at a lower price and with Toyota reliability.
End of the Twin-Cam Era
The second-generation Celica marked the end of the R-series twin-cam engine era. The 18R-G would be replaced by the more modern 21R and later 2S engines in subsequent Celica generations. The change reflected Toyota's broader shift toward fuel-efficient, emissions-compliant engines in response to the oil crises of the 1970s.
For enthusiasts, the loss of the 18R-G was keenly felt. The later engines were more refined and more efficient, but they lacked the 18R-G's high-revving character and the emotional connection that came with twin side-draft carburettors and a head that was designed for performance rather than economy.
Motorsport
The Celica's motorsport involvement was extensive, though it was in rallying that the nameplate achieved its greatest fame -- though that fame came largely with later generations (particularly the ST165 and ST205 in the World Rally Championship).
Circuit Racing
The first-generation Celica was campaigned in production car racing across Asia, Australia, and Oceania. In Japan, the 2T-G-powered Celica competed in touring car events. In Australia, the Celica was raced at state and national level, where its light weight and willing twin-cam engine made it competitive against larger, more powerful cars.
The Celica was a popular club racer. The 2T-G and 18R-G engines responded well to tuning -- race-prepared 18R-Gs could produce 160+ hp with twin Weber DCOE carburettors, a high-lift camshaft, and exhaust work. The lightweight body and reasonable handling made the Celica a competitive and forgiving platform for amateur racers.
Rallying
Toyota's rally programme began with the Celica in the 1970s. The first-generation Celica was entered in international rally events, including the East African Safari Rally, where its Toyota durability proved invaluable on the punishing African stages. The Celica RA40 continued the rally programme, competing in events across the world.
These early rally efforts laid the groundwork for Toyota's later domination of the World Rally Championship with the Celica GT-Four in the 1990s. The rally DNA that began with the A20 and A40 generations would evolve into one of the most successful rally programmes in history.
Australian Motorsport
In Australia, the Celica was a regular competitor in production car racing, rally events, and hill climbs. The car's combination of reliability, light weight, and tuneable engines made it a popular choice for both amateur and semi-professional competitors.
The Celica was particularly effective in rally, where its rear-wheel-drive layout and willing engine suited the varied surfaces of Australian rally stages. The 18R-G twin-cam engine, with its broad powerband and rev-happy character, was well-suited to the demands of rally driving.
Cultural Impact
The Celica's cultural impact in Australia was significant. It was one of the cars that changed the perception of Japanese vehicles from "cheap and cheerful" to "desirable and sporting." In the 1970s, Toyota dealers in Australia actively promoted the Celica as a car for young professionals -- an aspirational vehicle that combined style with substance.
The Celica appeared regularly in Australian motoring magazines, where it was praised for its build quality, reliability, and driving enjoyment. It was the car that many Australians chose as their first sports coupe, and it created a generation of Toyota enthusiasts who went on to buy Supras, MR2s, and other sporting Toyotas.
In broader popular culture, the first-generation Celica has become a recognised icon of 1970s automotive design. Its clean proportions, sporting stance, and distinctive front end make it instantly identifiable. The liftback variant in particular has achieved cult status, with its unique body style attracting a dedicated following.

Legacy
The Toyota Celica proved that Toyota could build more than just reliable, practical transportation. It demonstrated that Japanese engineering could deliver style, performance, and driving pleasure -- qualities that had previously been the domain of European manufacturers. The Celica was Toyota's first sports car, and it established a sporting tradition that continued through the Supra, MR2, and AE86 Corolla.
For the Australian market, the Celica was transformative. It showed that a Japanese sports coupe could be as desirable as a European alternative, but with the added benefit of Toyota reliability, parts availability, and dealer support. The RA23 and RA40 are the cars that taught a generation of Australians to take Japanese sports cars seriously.
Today, the early Celica is appreciated as one of the most accessible and rewarding Japanese classics. It combines everything enthusiasts value -- light weight, a willing engine, engaging handling, and timeless styling -- with the one thing that distinguishes Toyota from every other manufacturer: the near-certainty that it will start every morning and get you home every evening.
