1991-1992 Opel Vectra A 1.7 TD (82 Hp)

The Opel Vectra A 1.7 TD, produced between September 1991 and July 1992, represents a significant offering from General Motors’ European arm, Opel, in the early 1990s. Introduced in 1988 as a replacement for the Ascona, the Vectra A was designed to compete in the highly contested European mid-size segment, prioritizing modern aerodynamics, spaciousness, and practicality. While Opel vehicles were not officially sold in the United States, the Vectra A’s engineering and market positioning mirrored GM’s global strategies, adapted to European preferences and regulations. The 1.7-liter turbocharged diesel sedan was a popular choice for those seeking an economical and reliable vehicle, embodying the growing demand for fuel-efficient powertrains in Europe.

Engine & Performance of the Opel Vectra A

The Opel Vectra A 1.7 TD is powered by an inline four-cylinder, 1.7-liter (1686 cm³ or 102.89 cu. in.) diesel engine, internally designated as the 17DT. This engine is transversely mounted at the front of the vehicle, delivering power to the front wheels via a five-speed manual transmission. Though not designed for high performance, the turbocharger provides respectable output for its class and era. The engine generates 82 horsepower at 4400 rpm, a competitive figure for a diesel of its size in the early 1990s. Crucially, it produces 123.91 lb.-ft. (168 Nm) of torque at 2400 rpm. This low-end torque is essential for everyday drivability, providing ample pulling power for urban traffic and highway cruising.

Performance figures for the 1.7 TD are pragmatic rather than sporty. Acceleration from 0 to 60 mph is estimated at 13.8 seconds (0-100 km/h in 14.5 seconds), with a top speed of 109.36 mph (176 km/h). These numbers position the Vectra A as a capable family sedan, prioritizing comfortable cruising over outright speed. The powertrain’s primary strength lies in its fuel efficiency, achieving a combined fuel consumption of 35.6 US mpg (6.6 l/100 km). This economy was a significant advantage for European buyers facing higher fuel costs. The precombustion chamber injection system, coupled with an overhead camshaft (OHC) valvetrain, contributes to the engine’s reliability and relatively smooth operation for a diesel of its time.

Design & Features of the Opel Vectra A

The Opel Vectra A is presented here in its four-door sedan configuration, accommodating five passengers. Its design represents a departure from the more angular styling of the Ascona. The Vectra A embraces a more rounded, aerodynamic aesthetic, evidenced by its commendable drag coefficient (Cd) of 0.29. This sleek profile enhances its modern appearance and contributes to improved fuel efficiency and reduced wind noise at higher speeds.

The sedan measures 174.49 inches (4432 mm) in length, 67.17 inches (1706 mm) in width, and 55.12 inches (1400 mm) in height, with a wheelbase of 102.36 inches (2600 mm). These dimensions provide a spacious cabin and a generous trunk capacity, ranging from 18.72 cu. ft. (530 liters) to 29.66 cu. ft. (840 liters) with the rear seats folded, making it highly practical for families and their belongings.

The 1991-1992 Vectra A, while lacking the advanced digital features of modern vehicles, offers essential amenities for its era. Standard features include hydraulic power steering, providing a direct steering feel. Safety is addressed with ventilated disc brakes at the front and drum brakes at the rear, supplemented by an Anti-lock Braking System (ABS), a significant safety advancement for the time. The suspension system utilizes a wishbone setup at the front and coil springs at the rear, balancing ride comfort and handling stability. The car rides on 175/70 R14 tires mounted on 14-inch wheel rims, providing a comfortable ride on various road surfaces.
