Introduced in late 1981 (at the Tokyo Motor Show), the B11s were the first front-wheel-drive Sunnys, predating by a year and a half the switch to front-wheel drive by their main Toyota Corolla rival, and were exported to the United States as the Nissan Sentra from the 1982 model year onwards. European sales began in May 1982, with this version of the Sunny going on sale at a time when front-wheel drive was quickly becoming the most popular layout on family cars in Europe. The B11 series shared its engines and much of its underpinnings with the Nissan Pulsar (N12) which launched around the same time, effectively providing the hatchback body style in this size class which in the European market was becoming the widely preferred configuration. Because the Sunny and Cherry/Pulsar had grown substantially to fill this market need, the supermini size class was filled by the Nissan Micra/March that also launched the same year. Ultimately, the Sunny and Cherry/Pulsar lines converged in the European market for the N13 generation in 1986.
