Fog delays start The 69th ADAC Westfalenfahrt was the fifth race of the season for the Porsche Endurance Trophy Nürburgring...
Introduced in 1989 (the year of the 911’s 25th anniversary), the 964 Carrera 4 was a significant new model for the company, but the 4-wheel drive system was deemed unsuitable for the company’s racing series. Manufactured alongside the Carrera 4 at the same time was the more traditional rear-wheel drive Carrera 2, but this model’s launch was only planned for a year later, in the hope that it would not detract from potential sales of the Carrera 4. The 1990 season was the first season that saw the 911-based model become the pillar on which the Porsche Carrera Cup series has been established.
