The Opel Vectra A 2.0i CAT (115 Hp) Automatic, produced between 1988 and 1992, represents a significant step forward for Opel in the mid-size family car segment. Replacing the aging Ascona and Manta models, the Vectra A aimed to offer a more modern, spacious, and technologically advanced package. While not officially sold in the United States, the Vectra was a popular choice in Europe, competing with vehicles like the Ford Mondeo, Volkswagen Passat, and Peugeot 405. This model, specifically the 2.0i CAT with automatic transmission, offered a balance of performance and convenience for buyers seeking a comfortable and reliable family sedan.
Opel Vectra A: A European Family Sedan
The Vectra A marked a departure from Opel’s previous designs, embracing a more aerodynamic and contemporary aesthetic. It was available in several body styles, including a four-door sedan (the focus of this article), a five-door hatchback, and a station wagon (estate). The “CAT” designation in the model name refers to the catalytic converter, indicating an effort to meet increasingly stringent European emissions standards. The automatic transmission option provided a more relaxed driving experience, appealing to a broader range of customers.
Engine & Performance
The heart of the Vectra A 2.0i CAT is its 1,998 cc (121.93 cu. in.) inline-four cylinder engine. This naturally aspirated engine, designated C20NE, produces 115 horsepower at 5,200 rpm and 170 Nm (125.39 lb.-ft.) of torque at 2,600 rpm. The engine utilizes multi-port fuel injection and an overhead camshaft (OHC) valvetrain, contributing to its relatively smooth operation and reasonable fuel efficiency for the era. Paired with a four-speed automatic transmission, the Vectra A 2.0i CAT achieves a 0-100 km/h (0-62 mph) acceleration time of 12 seconds and a top speed of 193 km/h (119.92 mph). While not a performance car, the powertrain provides adequate power for everyday driving and comfortable highway cruising. The weight-to-power ratio of 9.9 kg/Hp and a weight-to-torque ratio of 6.7 kg/Nm demonstrate a reasonable balance for a family sedan of its time. Fuel economy is rated at 7.5 l/100 km (31.4 US mpg) combined, and 10.5 l/100 km (22.4 US mpg) in urban conditions.
Design & Features
The Opel Vectra A sedan is a four-door, five-seater vehicle characterized by its relatively boxy, yet aerodynamic, silhouette. The design prioritized interior space and practicality. Key features included ventilated front disc brakes and disc brakes in the rear, providing adequate stopping power. The inclusion of an Anti-lock Braking System (ABS) was a notable safety feature for the time, enhancing braking performance and stability, particularly in adverse conditions. The steering system utilizes a hydraulic power steering rack and pinion, offering a responsive and comfortable driving experience. The interior was designed with practicality in mind, offering comfortable seating and a spacious trunk with a capacity ranging from 530 to 840 liters (18.72 to 29.66 cu. ft.) depending on the rear seat configuration. The vehicle rides on 195/60 R15 tires mounted on 15-inch wheel rims. The drag coefficient of 0.29 was considered respectable for a sedan of this era, contributing to improved fuel efficiency and reduced wind noise.
