1990 · 🇩🇪 Germany · 150 hp
The Calibra with Opel's 2.0-litre 16-valve C20XE engine produced 150 hp, making it the sporting entry-point below the all-wheel-drive Turbo. Renowned for its 0.26 Cd drag coefficient — one of the lowest of any production car at launch — it offered genuine GT-coupe character at an accessible price.
