Sotheby’s Motorsport has listed a 2003 Porsche 911 Turbo Coupe X50 for online auction, with bidding due to close on Tuesday, May 26, 2026, according to the lot page. The car is a 996-generation 911 Turbo showing 56,089 miles and is being offered by what the listing describes as its sole long-term owner of the past 23 years. (sothebysmotorsport.com) The sale is being run on Sotheby’s Motorsport’s online platform, where the lot is identified as number 9969. The seller location is listed as Lake Frederick, Virginia. ### Which 911 Turbo is being sold here? The car in the listing is a 2003 Porsche 911 Turbo Coupe with Porsche’s factory X50 package, a period performance option for the 996 Turbo. (sothebysmotorsport.com) Sotheby’s Motorsport says the car is powered by a Mezger-engineered 3.6-liter twin-turbocharged flat-six paired with a Tiptronic S automatic transmission and all-wheel drive. The X50 package is the key detail in the listing. Sotheby’s Motorsport says it raised output to around 450 horsepower through larger turbochargers and other factory upgrades derived from the 996 GT2. The lot page also says the package came with a stronger Tiptronic S transaxle. (sothebysmotorsport.com) ### Why does the X50 package matter on a 2003 car? Porsche did not offer a formal 996 Turbo S until later in the model run, and the X50 package became one of the most closely watched factory options on earlier 996 Turbos, according to collector-market listings and marque specialists. RM Sotheby’s has described the X50 as a “highly desirable” Turbo Power Kit on another 2003 911 Turbo, while other market listings describe it as the closest earlier 996 Turbos came to Turbo S specification. (sothebysmotorsport.com) The Sotheby’s Motorsport listing ties that appeal to factory hardware rather than aftermarket modification. The lot page says the car’s added output came from Porsche-optioned internals and tuning, with components linked to the 996 GT2.
