The Opel Corsa A Sedan (facelift 1987) 1.3 S, producing 70 horsepower, represented an entry-level offering within the Corsa A range. Introduced as part of the facelifted Corsa A line in 1987 and continuing through 1989, this variant aimed to provide affordable and economical transportation for the European market. The Corsa A, Opel’s direct competitor to the Ford Fiesta and Volkswagen Polo, was a significant step for the company, representing a move towards more modern, front-wheel-drive subcompact cars. The sedan body style, while less common than the hatchback in some markets, offered a more traditional appearance and increased trunk space, appealing to a different segment of buyers. This particular 1.3 S trim was positioned as a practical and fuel-efficient choice, prioritizing affordability over outright performance.

Powertrain & Engine Architecture
The 1.3 S variant was powered by the 13SB engine, a 1297cc inline-four cylinder unit. This engine utilized a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. Crucially, it employed a carburetor for fuel delivery, a common feature for vehicles of this era and price point. The carburetor, while simpler and less expensive than fuel injection, resulted in slightly lower fuel efficiency and less precise control over the air-fuel mixture. The engine produced 70 horsepower at 5800 rpm and 101 Nm (74.49 lb-ft) of torque at 3800 rpm. The engine was transversely mounted, driving the front wheels. The transmission was a five-speed manual gearbox, offering a reasonable spread of ratios for everyday driving. The 13SB engine was known for its relative simplicity and durability, making it a relatively easy engine to maintain.
Driving Characteristics
The Corsa A 1.3 S, with its 70 horsepower and relatively lightweight body, offered modest performance. Acceleration from 0 to 60 mph took approximately 12.4 seconds, and the top speed was around 102.53 mph. Compared to higher-spec Corsa A models equipped with larger engines (like the 1.6-liter), the 1.3 S felt noticeably slower, particularly when fully loaded or climbing hills. The five-speed manual transmission helped to keep the engine in its optimal power band, but the carburetor’s limitations were evident in occasional flat spots during acceleration. The steering was light and relatively precise, making it easy to maneuver in urban environments. The suspension, while basic, provided a comfortable ride on most road surfaces. The overall driving experience was geared towards practicality and economy rather than sporty performance.
Equipment & Trim Levels
The 1.3 S trim level was considered an entry-level specification. Standard equipment typically included basic steel wheels, cloth upholstery, and a simple dashboard layout. Power steering and central locking were generally not standard features on this trim, but could be added as optional extras. The interior was functional and durable, prioritizing practicality over luxury. Optional extras could include a radio, upgraded seat fabrics, and tinted glass. The Corsa A Sedan, even in its base trim, offered a reasonable level of equipment for its price point, making it an attractive option for budget-conscious buyers.
Chassis & Braking
The Corsa A Sedan featured a MacPherson strut front suspension and a twist-beam rear suspension. The front brakes were disc brakes, providing adequate stopping power, while the rear brakes were drum brakes, a cost-saving measure common in this class of vehicle. The suspension was tuned for comfort, providing a relatively smooth ride, but it wasn’t particularly sporty. The steering was rack and pinion, offering reasonable precision. The 13-inch steel wheels were fitted with 145/70 R13 tires. The chassis was relatively lightweight, contributing to the car’s fuel efficiency and handling.
Market Reception & Comparison
The Opel Corsa A 1.3 S was generally well-received as an affordable and reliable small car. Critics praised its fuel economy and ease of driving, but noted its lack of outright performance compared to more powerful rivals. Compared to the Volkswagen Polo and Ford Fiesta, the Corsa A offered a similar level of practicality and affordability. The 1.6-liter Corsa A models offered significantly more performance, but at a higher price point. The 1.3 S appealed to buyers who prioritized economy and reliability over sporty driving dynamics. Its fuel consumption of 7.6 l/100 km (30.9 US mpg) was competitive for its time.
Legacy
The Opel Corsa A 1.3 S, while not a particularly high-performance variant, remains a popular choice among classic car enthusiasts and those seeking an affordable and reliable vintage vehicle. The 13SB engine is known for its durability and relative simplicity, making it relatively easy to maintain and repair. Parts availability is generally good, although some components may be becoming increasingly difficult to find. Today, these Corsas are often sought after as affordable entry points into classic car ownership, offering a nostalgic driving experience and a glimpse into the automotive landscape of the late 1980s. The Corsa A laid the foundation for the continued success of the Corsa model line, which remains a popular choice in Europe today.
