The Opel Kadett E 1.6 S, producing 90 horsepower, was a mainstay of the Kadett E range produced between 1984 and 1986. Positioned as a mid-range offering, it bridged the gap between the more basic Kadett models and the higher-performance variants like the GSi. The Kadett E, built on the GM T-platform (internally known as 1HX0/A3), represented a significant step forward for Opel in terms of design, technology, and build quality, becoming one of the best-selling cars in Europe during its production run. This particular 1.6 S variant was aimed at buyers seeking a balance of affordability, practicality, and reasonable performance for everyday driving.

Powertrain & Engine Architecture
The heart of the Kadett E 1.6 S was the 16SH engine, a 1.6-liter inline-four cylinder unit. This engine utilized a single overhead camshaft (SOHC) valvetrain operating two valves per cylinder. Fuel delivery was managed by a carburetor, a common setup for the time, though less efficient and precise than fuel injection systems. The 16SH engine produced 90 horsepower at 5800 rpm and 126 Nm (93 lb-ft) of torque between 3800 and 4200 rpm. The engine’s relatively simple design contributed to its reliability and ease of maintenance. The Kadett E 1.6 S was typically paired with a five-speed manual transmission, although a three-speed automatic transmission was also available, albeit less common. The automatic transmission, while offering convenience, noticeably impacted acceleration and fuel economy.
Driving Characteristics
The 1.6 S with the manual transmission offered a reasonably engaging driving experience for its class. Acceleration from 0 to 60 mph took around 10.5 seconds, and it could reach a top speed of 112 mph. The engine felt responsive enough for everyday driving, with adequate torque for overtaking maneuvers. However, compared to the more powerful GSi models, the 1.6 S felt noticeably slower. The automatic transmission version suffered from sluggish performance, with the three-speed unit lacking the versatility of a five-speed manual. Gear ratios were optimized for fuel efficiency rather than outright performance. The Kadett E’s front-wheel-drive layout provided predictable handling, although it wasn’t particularly sporty.
Equipment & Trim Levels
The Kadett E 1.6 S typically came equipped with features considered standard for the mid-1980s. This included cloth upholstery, a basic instrument cluster, and manual windows and door locks. Optional extras included a sunroof, upgraded stereo systems, and central locking. The interior design was functional and durable, prioritizing practicality over luxury. The 1.6 S trim level generally offered a step up in interior trim quality compared to the base models, with slightly more comfortable seats and improved dashboard materials.
Chassis & Braking
The Kadett E utilized a MacPherson strut front suspension and a twist-beam rear suspension. This setup provided a comfortable ride, although it wasn’t particularly sophisticated. The 1.6 S models typically featured disc brakes on the front wheels and drum brakes on the rear. The braking system was adequate for normal driving conditions, but lacked the stopping power of the larger brakes found on the GSi models. Stabilizer bars were fitted to both the front and rear axles to reduce body roll during cornering.
Market Reception & Comparison
The Kadett E 1.6 S was well-received by European buyers as a practical and affordable family car. Critics praised its fuel efficiency, reliability, and comfortable ride. However, the carburetor-equipped engine was often criticized for its lack of refinement and relatively low power output. Compared to the 1.3-liter base models, the 1.6 S offered a noticeable improvement in performance. In contrast to the more expensive GSi models, the 1.6 S provided a more economical option for buyers who didn’t prioritize sporty handling or high-speed acceleration. The 1.6 diesel version offered even better fuel economy, but at the expense of performance.
Legacy
The Opel Kadett E 1.6 S remains a popular choice among classic car enthusiasts today. The 16SH engine is known for its durability and relatively simple maintenance requirements. Parts availability is generally good, although some components can be difficult to find. The Kadett E’s robust construction and reliable powertrain have ensured that many examples are still on the road today. While not a particularly collectible model, the 1.6 S represents a well-rounded and affordable entry point into the world of classic Opel ownership. The Kadett E, as a whole, is remembered as a pivotal model for Opel, solidifying its position as a major player in the European automotive market.
