A Porsche race car from the '90s is expected to sell for $3 million this weekend

A Porsche race car from two decades ago is for sale at an RM Sotheby's auction to be held concurrent to the 2016 Historic Grand Prix of Monaco this weekend.

The 911 GT1 Evolution, which competed with the McLaren F1 and Mercedes CLK AMG GTR in a particularly speedy era of endurance racing, is estimated by the auction house to sell for about $3 million.

The car is not a 911 GT1 Straßenversion, the softened, road-car version of the GT1. It is an actual 13-race winner, one of only 18 built and of the same type that delivered Porsche its record-breaking 16th win at Le Mans.

This particular car won three Canadian GT championships from 1999 to 2001 and competed in the Rolex 24 at Daytona.

Somehow, the car - powered by a twin-turbo flat six making greater than 600 horsepower that sounds like this - is registered as road-legal in the UK. Yes, it can be driven on real roads.

Here it is.
