When the FIA banned Group B in 1986, the smaller Group A moved up to the front row for 1987. It was based on near-production cars, mainly from the compact class. According to the regulations, the basic cars had to have at least four seats. In contrast to the permissive rules of Group B, manufacturers in Group A were required to produce significantly more homologation vehicles. Within one calender year, 2,500 units of the respective base car had to be produced. These had to share special add-on parts and the most important technical details with the rally car. Nevertheless, there were once again many car brands that wanted to take on the competition. They saw an advantage in being able to link sporting success directly with a vehicle that could be purchased.<\/p>\n\n\n\n

Sunny GTi-R was created for Group A<\/h3>\n\n\n\n

For 1990 Nissan developed the then new seventh model generation of the Sunny into a rally car. As basis they used the three-door variant. In contrast to the normal series models here an all-wheel drive was used, which was based on the already before developed ATTESA system of Nissan. For this purpose, the Sunny GTi-R received a new transmission tunnel to guide the propshaft to the rear axle. A five-speed manual gearbox provided power from the two-liter, four-cylinder turbocharged engine. A Garrett GT28 turbocharger and an intercooler installed above the engine helped the car produce 162 kW\/220 hp and 267 Nm of torque. To withstand the 0.73 bar boost pressure, the cylinder heads were made of aluminium with sodium-filled exhaust valves. Likewise, Nissan manufactured the engine block from aluminium and also used it in the Primera for the British Touring Car Championship.<\/p>\n\n\n
