The Opel Kadett E Cabrio 1.4i, produced between 1990 and 1991, represented the final iteration of the popular Kadett E series, and the last open-top Kadett offered by Opel. Positioned as an affordable entry into the convertible market, it aimed to provide stylish, open-air motoring to a broader audience. This variant utilized a relatively small displacement engine paired with a five-speed manual transmission, making it a popular choice for those prioritizing fuel economy and lower running costs.

Powertrain & Engine Architecture
The Kadett E Cabrio 1.4i was powered by the 14NV engine, a 1389cc inline four-cylinder unit. This engine featured a single overhead camshaft (SOHC) valvetrain with two valves per cylinder. Unlike later Opel engines, the 14NV utilized a carburetor for fuel delivery, a cost-saving measure that contributed to its affordability. The carburetor, while simpler than fuel injection, required periodic adjustment to maintain optimal performance. The engine produced 75 horsepower at 5600 rpm and 108 Nm (79.66 lb-ft) of torque at 3000 rpm. The five-speed manual transmission offered a relatively long gearing, prioritizing fuel efficiency over outright acceleration. The engine’s transverse mounting and front-wheel-drive configuration were typical for European compact cars of the era.
Driving Characteristics
The 1.4i Cabrio, with its modest power output and relatively lightweight construction, offered a comfortable and economical driving experience. Acceleration was adequate for everyday driving, but it wasn’t particularly brisk. The long gearing of the five-speed manual transmission meant that the engine needed to be revved to access its power, especially when overtaking. Compared to the more powerful Kadett E variants, such as those equipped with the 1.6 or 2.0-liter engines, the 1.4i felt noticeably slower. However, the lighter engine weight contributed to better handling balance. The steering was light and precise, making it easy to maneuver in urban environments. The suspension, while basic, provided a reasonably comfortable ride, absorbing most road imperfections without excessive body roll.
Equipment & Trim Levels
The Kadett E Cabrio 1.4i was generally equipped with a basic level of standard features. Interior upholstery typically consisted of cloth seats, and the dashboard featured a simple, functional design. Power steering was often an optional extra, as were electric windows and central locking. The convertible top was manually operated, adding to the car’s affordability. Trim levels were relatively limited, with most examples featuring similar equipment. Optional extras included upgraded audio systems and alloy wheels. The interior space was adequate for four adults, although rear seat legroom was somewhat limited.
Chassis & Braking
The Kadett E Cabrio utilized a MacPherson strut front suspension and a twist-beam rear axle. 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 steering was a rack-and-pinion system, offering precise control. The car’s relatively light weight helped to compensate for the limitations of the braking system. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Kadett E Cabrio 1.4i was generally well-received as an affordable and stylish convertible. Critics praised its value for money and its comfortable ride. However, some reviewers noted its lack of outright performance compared to more powerful rivals. Compared to the higher-spec Kadett E Cabrio models, the 1.4i offered a more economical option, appealing to buyers who prioritized fuel efficiency and lower running costs. The 1.4i was also a popular choice for first-time convertible buyers. Fuel economy was a strong point, averaging around 35-40 mpg in mixed driving conditions.
Legacy
The Opel Kadett E Cabrio 1.4i, while not the most powerful or technologically advanced version of the Kadett E, remains a popular choice among classic car enthusiasts. The 14NV engine is generally considered to be reliable, although it requires regular maintenance to prevent issues. The carburetor can be a source of problems if not properly maintained. Today, well-maintained examples of the Kadett E Cabrio 1.4i are becoming increasingly collectible, particularly those with low mileage and original features. The car’s simple construction and readily available parts make it relatively easy to maintain and repair. It represents a nostalgic reminder of a time when affordable, open-top motoring was within reach of a wider audience.
