In the 1980s, when Audi Quattro was introduced into the World Rally Championship, the 4WD element became indispensable for aiming victory with the success of Audi Quattro. Meanwhile, in 1982, a new regulation by FIA came into effect. In 1983, when WRC was to be held in accordance with its new Group B regulations, Toyota introduced their new machine TA-64 Celica Twin Cam Turbo. The Group B regulations eased production restrictions and increased the freedom in machine development. While each manufacturer was turning to special machines such as 4WD midship, Toyota selected 2WD rear-wheel-drive for Group B machine.

The suspension also used McPherson struts on the front and 4-link rigid on the rear. By adopting a simple mechanism, it weighted 1150 kg and was highly durable and reliable. The engine used a twin plug with an in-line 4-cylinder DOHC8 valve displacement of  2090cc and equipped with two ignition plugs per cylinder. The turbocharged engine used the multiplication factor of 1.4 to calculate engine displacement that fitted in the displacement class of 3 liters or less. In addition, the Celica was equipped with a KKK turbocharger and demonstrated a power of 320 to 340 horsepower.

Nunu has replicated the design in 1/24 scale and detail in this plastic model kit with high detailed chassis and complete exhaust system and removeable front bonnet to display the engine bay.
