The Opel Kadett is a compact automobile produced by the German automaker Opel, a subsidiary of Stellantis. Introduced in 1935, the Kadett nameplate was applied to several distinct model generations spanning over six decades, concluding with the final generation in 1991. Throughout its production run, the Kadett was positioned as Opel’s entry‑level family car, competing primarily in the C‑segment (small family car) market.

Technical Overview
- Engine Types: Throughout its life, the Kadett employed a variety of inline‑four engines, ranging from modest 1.1 L side‑valve units to performance‑oriented 2.0 L 16‑valve engines in the later G‑generation. Diesel options were limited to 1.5 L naturally aspirated units.
- Transmission: Standard manual gearboxes (3‑speed to 5‑speed) were offered; select models featured a 3‑speed automatic (Torque‑Flite) in the late 1970s and early 1980s.
- Layout: All Kadett generations after the original 1935 model utilized a front‑engine, front‑wheel‑drive layout, aligning with industry trends for compact cars.
- Suspension: Independent front MacPherson struts paired with a rear semi‑independent torsion‑beam or trailing‑arm setup, depending on the generation.
Market Position and Reception
The Kadett consistently served as Opel’s volume seller in Europe, particularly in Germany, the United Kingdom (as the Vauxhall Kadett), and other markets where Opel had a presence. It was praised for its pragmatic engineering, relatively low running costs, and versatile body‑style options. The sport‑oriented “GT/E” and “GSi” models attracted enthusiasts seeking higher performance within the compact segment.
Motorsport and Cultural Impact
- Rallying: The Kadett, especially the GT/E and later GSi versions, participated in national rally championships during the 1970s and 1980s, achieving modest success.
- Pop Culture: The Kadett appeared in various German media productions and is often referenced as a representative family car of the late‑20th‑century European automotive landscape.
Legacy
The Opel Kadett’s discontinuation in 1991 marked the transition to the Opel Astra, which retained much of the Kadett’s mechanical architecture while adopting a more contemporary design language. The Kadett name remains recognizable among classic‑car collectors, with well‑preserved examples frequently exhibited at automotive heritage events.
