The Opel Vectra A, particularly the facelifted version introduced in August 1992, represented a significant step forward for Opel in the mid-size family car segment. Replacing the aging Ascona and Manta, the Vectra aimed to offer a more modern and refined driving experience. This generation, produced until July 1995, was a crucial model for Opel, establishing a foothold in a competitive market dominated by Ford and Volkswagen. The 1.8 S variant, equipped with a 90 horsepower engine and automatic transmission, was a popular choice for buyers seeking a balance of performance and convenience. While not initially a major seller in the UK (where it was sold as a Vauxhall Vectra), the Vectra A found success across continental Europe, becoming a common sight on roadways.
Opel Vectra A (Facelift 1992) 1.8 S: An Overview
The Vectra A facelift, launched in 1992, brought subtle but important changes to the original design. These included revised front and rear styling, improved interior trim, and refinements to the engine range. The 1.8 S model, as detailed here, was positioned as a mid-range offering, providing a step up in performance from the base 1.4-liter engine. Its combination of a relatively fuel-efficient 1.8-liter gasoline engine and the ease of an automatic transmission made it an appealing option for family buyers and commuters. The Vectra A was a four-door sedan, offering seating for five passengers and a reasonably spacious trunk.
Engine & Performance
The heart of the Vectra A 1.8 S is its 1796 cc (109.6 cubic inches) inline four-cylinder engine, designated the C18NZ. This naturally aspirated engine produces 90 horsepower at 5400 rpm and 145 Nm (106.95 lb-ft) of torque at 3000 rpm. While not a performance powerhouse, the engine provides adequate power for everyday driving. The power-to-weight ratio of 12.3 kg/Hp (81.2 Hp/tonne) reflects this balance. The engine utilizes a single-point fuel injection system, a common technology for the era, and features an overhead camshaft (OHC) valvetrain with two valves per cylinder. Acceleration from 0 to 100 km/h (0-62 mph) takes approximately 15 seconds, while 0-60 mph is achieved in around 14.3 seconds. The top speed is rated at 177 km/h (109.98 mph). Fuel economy figures are respectable for the time, with combined consumption of 7.4 l/100 km (31.8 US mpg or 38.2 UK mpg).
Design & Features
The Opel Vectra A facelift presented a conservative, yet modern design for the early 1990s. Its sedan body style was typical of the segment, prioritizing practicality and passenger space. The car’s dimensions – 4432 mm (174.49 in) in length, 1706 mm (67.17 in) in width, and 1400 mm (55.12 in) in height – positioned it squarely within the mid-size category. The interior focused on functionality, offering comfortable seating for five and a trunk capacity ranging from 530 to 840 liters (18.72 to 29.66 cubic feet) depending on the rear seat configuration. Safety features, while limited by the standards of today, included an Anti-lock Braking System (ABS) as an available option. The Vectra A featured hydraulic power steering and a four-speed automatic transmission, enhancing driver comfort and ease of use. The drag coefficient of 0.29 was a reasonable figure for the period, contributing to fuel efficiency.
