This monstrous Porsche race car from the 90s expected to sell for $3 million

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 1999-2001 and competed at 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 United Kingdom. Yes: it can be driven on real roads.

Here it is.
