In 1990, the N14 model finally saw Nissan conform to the rounded look. There was no Holden equivalent. The Vector name continued in Australia in this series, from 1992 to 1995. It continued to be offered in New Zealand as the Sentra. In Europe, the Sunny name continued, applied to three, four and five-door models, alongside the Sunny California station wagon from Japan (called either the Sunny Estate or Sunny Traveller). The Langley and Liberta Villa models were not offered. There was no N14 Pulsar offered in the US either.

This generation was badged as the Nissan Sabre in South Africa, and the Nissan Sunny in Europe. The Pulsar was Wheels magazine's Car of the Year for 1991. Also, a coupé model was offered in this generation, called the Nissan NX100.

The N14 series also saw the introduction of the Nissan Pulsar GTi-R (labelled Sunny GTi-R in Europe). It featured a turbocharged SR20DET engine producing 169 kW (230 hp JIS) of power, as well as the ATTESA all-wheel drive system.

The GTi-R, which was identified as a RNN14 model, was entered by Nissan into the World Rally Championship. However, it did not prove to be very competitive, and many believe it was hampered by excessive weight over the front wheels, causing a deficiency in handling where the car could understeer excessively. The GTi-R raced under the Nissan Motorsport Europe banner. It was more competitive in the hands of privateers, winning the Group N class of the World Championship in the hands of Grégoire de Mévius. It also proved popular in the European Rallycross Championship.
