Initially launched in 1966, the Sunny has seen various iterations, each bringing new features and improvements. This article explores the history, technical specifications, and unique aspects of each generation, offering a detailed look at one of Nissan's most enduring models.

B10 Series: The Beginning

Introduction

The B10 series, launched in April 1966 in Japan, marked the debut of the Nissan Sunny. Exported as the Datsun 1000, it came in two body styles: a two-door sedan (B10) and a family wagon (VB10). The B10 was powered by an A10 engine with a displacement of 988 cc, producing 56 horsepower. It was available in two trims: Deluxe (DX) and Standard.

Market Reach

The B10 series was not sold in the U.S. or Mexico but found markets in Canada, Panama, Europe, and other regions. In October 1967, a four-door version was introduced, followed by a coupe (KB10) in October 1968. The coupe, known as the Nissan Sunny Coupe in Japan, was available in various trims, from Standard to GL (luxury).

Unique Features

The coupe model was unique to Australia, where it was renamed the Datsun 1000 Coupe. It featured a high-compression engine with a different Hitachi carburetor and dual exhaust, boosting its power to 66 HP. Unlike other models, the coupe was exclusively right-hand drive (RHD).

Production Timeline

Despite its initial success, the B10 series saw a short production run. The 1970 models, introduced in July 1969, featured slight cosmetic changes. Production ceased in December 1969, just six months after the 1970 models hit the market.

B110 Series: A New Era

Technical Specifications

The B110 series was slightly larger than its predecessor, designed to compete with the Toyota Corolla. It featured MacPherson strut front suspension and offered optional front disc brakes. The Nissan A-12 engine was known for its fuel efficiency, achieving 28.7 mpg in the city and 37.9 mpg on the highway, according to U.S. government ratings.

Market Impact

At its U.S. launch, the Datsun 1200 was priced at $1,866, making it an affordable option for many consumers. Its fuel efficiency and affordability contributed to its popularity.

PB110 Series: The Performance Upgrade

In April 1971, Nissan introduced the PB110 series, featuring the Sentra 1400 coupe. This model marked a departure from the A-series engines, incorporating a new 1428 cc SOHC engine that delivered 85 to 95 horsepower, depending on the configuration.

B210 Series: The Third Generation

Introduction

The B210 series, launched in 1973, represented the third generation of the Nissan Sunny. Marketed as the Datsun B210 in the United States, it was available in four-door sedan, two-door coupe, and three-door hatchback body styles. Trims included Standard, Deluxe, GL (KPB210), and GX.

Technical Specifications
