The 1970 Citroen GS Birotor holds an edge across most measurable criteria, offering more power, quicker acceleration, higher top speed. That said, the 1934 Citroen Traction Avant 11B brings better value and remains a compelling choice for enthusiasts who value Citroen heritage. The right pick depends on whether you prioritize specifications or the intangible qualities that make a car truly special.
Within the Citroen stable, the 1970 Citroen GS Birotor and 1934 Citroen Traction Avant 11B represent different approaches to performance and purpose. Both carry the Citroen badge, yet each carves out its own distinct identity. The 1970 Citroen GS Birotor holds a clear advantage in raw power with 107 hp compared to 56 hp, a 51-horsepower difference that shapes the driving experience. Under the hood, the contrast is notable: the Citroen GS uses a Twin-rotor Wankel displacing 1,990 cc, while the Citroen Traction Avant relies on a Inline-4 OHV with 1,911 cc. In the sprint to 60 mph, the 1970 Citroen GS Birotor edges ahead at 13.5 seconds versus 23.0 seconds.
