1989 Porsche 911 Turbo ‘Flachbau’

Since its debut in 1975, the Porsche 911 Turbo has set a new standard for performance, not only for future 911 models, but also for the entire supercar category. The first iteration to feature forced-induction, the “930” model delivered lightning-fast acceleration and a striking aesthetic, including flared wheel arches, wide tires, and a “whale tail” spoiler inspired by the highly competitive IROC racers.

For those seeking an even more distinctive ride, the “M505” package was available as an option, which transformed the vehicle with a 935-inspired Flachbau, or “Slant-Nose,” body style. This option dramatically altered the appearance of the 911 with louvred wings, pop-up headlights, straked side vents, and wider rear wings. Although an expensive option that was undervalued at the time, the unique body style has since become one of the most coveted features of this 911 generation.
