As GT racecars have to be based on road cars, Porsche tweaked the 911 GT1 to the crazy GT1 Strassenversion. The Porsche 911 GT1 Strassenversion slots between the between the F40 rivaling 959 and the Carrera GT. The 911 GT1 Strassenversion was considered to be one of the marque's most extreme of road cars.
For the 1997 season, the GT1 received a revised suspension, bodywork, and headlights. Dubbed the GT1 Evo, it didn't win that season. Still the 1998 season saw the racer incorporating a lightweight carbon-fiber chassis, and the 911 GT1-98 took a one-two finish.
In 1997 Porsche began running a small amount of homologated customer cars, dubbed the "Strassenversion". They were more user friendly and had detuned suspensions, gear ratios and engine with 544bhp, with a more refined interior.
Still, the Strassenversion sprinted to a 100km/h in 3.6s and a possessed a 312km.h top speed.
A scarce 25 examples were built and retailed for $912,000.
This particular model that is heading to the auction block is the only unit to be imported into the US. The auction will happen at the RM Auction's Monterey Sale on August 18 with an estimated value of US$1.25 to US$1.4 million.
Interestingly another Strassenversion is currently for sale at DuPont Registry. Claimed to be the last unit manufactured and in "museum condition", the car had just completed a service at the Porsche factory in Germany and is priced at a staggering US$2,325,000.
