The task of the automobile and each of its individual subgenres has constantly been changing to adapt to new demands, but more recently the role of the car as an investment has become the norm and unfortunately, it seems as if the models that are the most fun to drive and that should be more prevalent on the road are the types that become garage queens. Thankfully, Silverstone Auctions' May Sale gives you a chance to right this wrong when the 1993 Porsche 911 Turbo S Leichtbau goes to the auction block.

Translated from German the word "Leichtbau" means "lightweight construction," alluding to the design philosophy used to build this highly limited 86-model run of the 911 Turbo S. This particular example is chassis number 51 and it left the factory on December 13th 1992 with hefty upgrades over the 911 of its time. "The Leichtbau is one of the most exciting 911s available with unique rarity and stunning looks," explains Harry Whale, classic car specialist at Silverstone Auctions. "Being 40 millimeters lower, 180kg lighter and with an additional 61 horse power, the Leichtbau is uber powerful and a very exciting proposition for Porsche enthusiasts."

The weight loss was managed by using aluminum for the doors, thinner glass, thinner carpets, and a kevlar luggage lid and rear spoiler. Even now, the Leichtbau is impressive, making a staunch 381 horsepower out of a turbocharged 3.3-liter engine mated to a G50 five-speed gearbox. With 68,868 km (43,042 miles) on the odometer, this rare 911 Turbo S Leichtbau is expected to fetch more than half a million dollars at auction. Helping raise the price is the fact that this example is one of only six painted in Gloss Black, which is complimented by a black leather interior and tri-tone Recaro seats that, along with the steering wheel, are set in Rubystone.

As for its condition, it's worth noting that even with relatively high mileage for a collector's car, this 911 has only done 1,871 miles per year, meaning it's not implausible to expect an immaculate piece to showcase at the auction block. Get those check writing hands ready come May 13 when the auction takes place.
