Street-legal Porsche 911GT1 Evolution hitting the auction block image

An incredible and truly unique 1997 Porsche GT1 Evolution will go under the hammer at a RM Sotheby’s auction in May taking place in Monaco, where it’s expected to harness anything from $2.97 million to $3.3 million.

While you may be fooled by its racing appearance, the model can actually be used legally on public roads according to RM Sotheby’s as we’re dealing with a former racer that has been converted to street legal use – it’s something different from the actual 911 GT1 Straßenversion that comes directly from Porsche’s production location with street-legal status. The model also has a good racing pedigree as it’s the holder of 13 races out of a total of 31 starts and also the winner of the Canadian GT championship during three consecutive years: 1999, 2000 and 2001.

The model’s core is the strong biturbo 3.2-liter flat-six engine churning out in excess of 600 horsepower (447 kilowatts) – the Straßenversion is a tad slower at “only” 544 hp and is also no less than 220 pounds (100 kilograms) heavier. This very unique 1997 Porsche GT1 Evolution is a true gentleman’s racer dream as it has all the necessary DNA – and its value might be unique considering only one unit of its kind exists. We’re also pretty much betting the value range set by RM Sotheby’s to be exceeded in Monaco – the 911 GT1 Straßenversion for example, which has been produced in 25 units, is worth well over $2 million any given day.
