23. 1964 Porsche 911
The original Porsche 911 was a luxury sports car manufactured by Porsche AG of Stuttgart, Germany. The famous, distinctive, and durable design was introduced in autumn 1963 and built through 1989. Succeeded by a modified version, it was referred to internally as the Porsche 964 but was still sold as the Porsche 911, as are current Porsche models. From its inception, the Porsche 911 was modified both by private racing teams and the Porsche factory itself for racing, rallying and other types of motorsports competition. In the automotive world, the original Porsche 911 series is often cited as the most successful motorsports competition car ever, mainly the powerful 911-derived 935 which won 24 Hours of Le Mans.
