Toyota Supra Mark I


Celica
The Toyota Supra was one of Toyota’s most popular sporting cars that gained many, many fans and spawned many racing enthusiasts and Supra lovers all over the world. The Mark I is the first generation of the car and ran from 1979 to 1981. The Supra was derived from the Toyota Celica, and was then known as the Toyota Celica Supra until its third generation, then the Celica was dropped and it was essentially its own car. The assembly of this masterpiece was done strictly in Japan, and the body style consists of 2+2 fastback GT coupe format. The look of the Mark I was longer and wider when compared to the Celica, and the engine of the first four generations can trace their direct engine roots to the Toyota 2000GT.

The overall dimensions of the car with wheelbase at 2628.9mm, a length of 4615.2mm, a width of 1651mm, a height of 1290.3mm and a curb weight of 2800lbs, where there were subtle variations as the years rolled on. The first year of production of the Supra, named the Toyota Celica XX, saw the car having all modern conveniences of the period of power windows and locks, cruise control, sunroof (optional), fliptop arm rests, tilt steering wheel, deep zippered pockets, a tonneau cover, AM/FM/MPX 4 speaker radio, analog clock and tachometer. The engine was completely changed from the four cylinder of the Celica to the Inline 6, and the first year saw two engines on different sides of the pond; 2.6 litre (2563cc) 12 valve SOHC inline 6 engine (4M-E), and the 2.0 litre (1988cc) 12 valve SOHC inline 6 engine (M-EU) that both out putted 110hp (82kW) and 184 Nm (136 ft-lbs). They were the first Toyota engines to have electronic fuel injection. They also had either a four speed automatic or a five speed manual transmission with overdrive gear.

The solid rear axle configuration was kept from the Celica, which had optional limited slip differential. The car has standard four wheel disc brakes, which suspension that consists of MacPherson Struts and stabilizer bar at the front, and four link suspension with coil springs, stabilizer bar, and lateral track bar at the back. In 1980, the changes that occurred to the car was a increase performance engine of 2.0 litre (1988cc) 12 valve SOHC Turbocharged inline 6 engine that delivered 145hp (108kW), and a torque of 211 Nm (156 ft-lbs). It was the first Toyota engine to have a turbocharger, and it was outfitted with a Garrett T03 Turbo, but was not intercooled. There were also a few aesthetic changes like the addition of mudflaps with “Celica” on them, redesigned side mirrors, bigger aluminum rims, leather trimmed seating, and climate control.

In 1981, the final year of the Mark I, there was a massive engine upgrade with a (2759cc) 2.8 litre 12 valve SOHC engine but achieves 116hp (87kW) and a torque of 197Nm (145ft-lbs). The automatic transmission was also revamped as the Toyota A43D, as it attained a final drive setting. The change of the Mark I saw the Supra achieve acceleration from 0-60mph 10.24 seconds and the quarter mile in 17.5 seconds. It was a highly impressive performance at the time, and it was considered a supercar for the road. The last big addition was the sports package that offered raised white letter tyres, sport suspension, back and front spoilers, and the first introduction of the 8-track cartridge in any Supra.

Toyota Supra Mark II


Celica
The Toyota Supra Mark II was the eventual successor to the first generation of the Supra, and this second generation ran from 1982-1986 with a host of improvements and modifications than its predecessor, but also went through a lot of changes over its four year run as well. The Mark II was assembled in Japan, and this was another model that had the direct link with the Toyota 2000GT, especially with its engine. The sportscar was also known as Celica XX or Celica Supra MK II in some parts of the world, and it was based on a MA6x platform.

The fastback car has a 2+2 design with differences in the front look of the car, as well as the introduction of the retractable headlamps, and there was also an increase in wheelbase and length to accommodate its larger engine. The overall dimension of the car includes a wheelbase of 2613.7mm, a length of 4660.9mm, a width of 1719.6mm, a height of 1320.8mm, and a curb weight of 3000lbs. The Supra was also distinguishable in some places by the use of the performance class (P-type) or the luxury class (L-type), where mechanically they were the same but aesthetics, technology, and size differed over the years. The first year of production saw the Supra with the 2.8 litre (2759cc) 12 valve with 2 valves per cylinder DOHC 5M-GE engine that outputted 145bhp (108kW) of horsepower and 210Nm (155ft-lb) of torque.

The compression ratio measured 8.8:1 and had a vacuum advanced distributor, resulting in 0-60mph in 9.8 seconds and the quarter mile in 17.2 seconds. The Supra also featured four wheel independent suspension with MacPherson struts at the front and semi-trailing arm suspension with stabilizer bar and coil springs at the rear. The transmission was W58 five speed manual or A43DL four speed automatic with overdrive gear and locking torque converter, and the brakes consisted of four wheel disc brakes.

For the second year of production the only changes were in the horsepower to 150bhp (112kW) and the torque to 216Nm (159ft-lbs), as the increase came from the altered gear ratios and the new transmission of A43DE four speed. The new transmission was the first to feature “Electronically Controlled Transmission” ECT, allowing the driver to choose between “power” and “Normal” driving modes by the touch of a button. The third year saw quite a lot of changes for the five speed transmission Supra MK II as performance increased yet again to 160bhp (119kW) and a torque of 221Nm (163ft-lb), through redesigning the intake manifold with “D” shaped intake runners and increasing the compression to 9.2:1.

The exterior got wrap around turn signals, and the interior aesthetics were changed to a new look.

The last two years saw the Supra being altered greatly again, as both manual and automatic cars got a performance increase of 161bhp (120kW) with a torque of 229Nm (169ft-lb), as the engine got a redesigned throttle position sensor (TPS), a knock sensor, and an EGR system. The increase in power results in a 0-60mph in 8.4 seconds, and the quarter mile in 16.1 seconds at a top speed of 85mph (137km/h). The other changes occurred to the overall looks and interior amenities of the car.

The second generation of an iconic car was very successful in the US as it won awards for “Import Car of the Year by Motor Trend”, and made “Car and Driver” magazine’s “Top Ten Best List” for both 1983 and 1984.
