Pictured here is the only road-legal example of Porsche's 911 GT1 Evolution race car, and it's headed to RM Sotheby's upcoming auction in Monaco. It's not only extremely rare, it comes with a winning pedigree, having won 13 out of 31 starts. Power comes from a 3.2-liter flat-6 engine delivering over 600 horsepower. An aerodynamic package is also accompanied by modified headlights, giving a unique look to this one and only GT1 Evo registered for use on public roads. RM Sotheby's estimates that the car will fetch about about 3,000,000 euros ($3.3 million) when it hits the auction block in May.
