The Opel Kapitän P2 (1959–1963) marked a new era in Opel’s design, with a fresh grille, sharper body lines, and an angular roof profile, while retaining the panoramic windscreen. Built between 1959 and 1963, this model was powered by a revised 2.6L inline-six engine that offered enhanced performance with an oversquare design (bore x stroke: 85 x 76.5 mm). It reached a top speed of 150 km/h (93.2 mph), accelerated to 100 km/h in 16 seconds, and achieved fuel consumption of 12 L/100 km (20 mpg‑US).
Drivers could select from three transmission options: a 3-speed manual, a 4-speed manual with overdrive, or from 1960 onward, a 3-speed Roto-Hydra-Matic automatic. With dimensions that emphasized size and presence (a length of 4,831 mm and a curb weight of 1,340 kg), the Kapitän P2 became Opel’s best-selling six-cylinder model, with 145,618 units produced—a record in the Kapitän line. This period was also notable for Opel's large car success in Europe, as the Kapitän and its sibling, the Admiral, became the top-selling six-cylinder sedans in Europe in 1960, though they generally competed at a lower level than Mercedes-Benz in the luxury market.
