A sportier version of the 200B sedan was released in June 1978. The new SX featured a revised grille, front spoiler, alloy wheels, revised door and seat trim (striped seat inserts) and tachometer, while the suspension was altered to improve handling. The colours available for this model were simply blue, white or red, and the only transmission available was a 4-speed floor shift.
Significantly the SX was a unique model to Australia, the added input from Nissan’s Australian design engineers signified a step away from just assembling cars. This in turn led to the locally built Datsun’s, and later Nissans, being re-engineered to better suit Australian conditions, with many components being sourced locally – a tradition that would continue right up until 1991, when Nissan ceased local manufacture.
The first significant change came in October 1977, with the introduction of the NAPS-Z (Nissan Anti Pollution System) engines, and a change to large bumpers with rubber end caps. In October 1979, the 200B was revised with a new grille, bumpers, seats, trim and dashboard. The seats were a unique Australian design for the locally built cars. In 1978 the range was updated with new dual rectangular headlights and a new grille - although this update did not appear in all markets.
In 1980 a limited edition 200B Aspen GL sedan was released, it featuring distinctive shadow tone paint available in green, blue or grey. Both the 180B and 200B models were extremely popular with Australian motorists, although it is rare to see one on the roads today. The time is fast approaching when 70's nostalgia buffs will lust for a good clean example, only to find there are none.
