• This Koenig-modified Porsche 930 Road Runner could sell for nearly $200,000 at auction.
  • The wild fiberglass body panels on the 911 Turbo are pure ‘80s excess and extravagance.
  • The 911’s 3.3-liter twin-turbocharged engine now produces between 473 hp and 542 hp.

Through the 1980s and 1990s, Koenig Specials earned a reputation for transforming European sports cars and supercars into high-powered, head-turning machines. Among their most flamboyant creations was the 930 Porsche 911 Turbo-based Road Runner, and one example now came up for auction through Broad Arrow Auctions. It’s tipped to sell for between $170,000 and $190,000.

Koenig had no interest in retaining the Porsche 911 Turbo’s historically understated looks, crafting instead a bespoke fiberglass body that can still cause a few necks to snap. This new kit includes a thoroughly revised front fascia with a new nose cone, custom quarter panels, and headlights lifted from a Porsche 928. The sides are particularly outlandish, with bulbous air vents, and wildly sculpted rear arches. While some of the bodywork looks as though it’s been melted after sitting in the sun for a little too long, there’s no denying this thing is dramatic.

At the back, Koenig added a huge ducktail spoiler together with a set of Audi 200 Turbo headlights. The car is finished in classic Guards Red. Even if the crazy styling doesn’t win you over, it’s hard to argue with some of the mechanical upgrades made.

 If ’80s Excess Had A Car, It Would Be Koenig’s 911 Turbo Road Runner

Koenig modded the 3.3-liter twin-turbocharged flat-six, allowing it to deliver between 473 hp and 542 hp depending on the boost pressure, more than double the 911 Turbo’s original power output. New cross-drilled and ventilated brakes have also been added, as well as a front strut brace, reinforced anti-roll bars, and Bilstein shocks. A new exhaust system rounds out the key changes.

Inside, the Road Runner features Champagne-colored leather upholstery that has aged gracefully over the years. According to the listing, the car has traveled 24,253 km (15,070 miles) and underwent a comprehensive engine-out service in January, costing over $20,000.
