Exceptionally Rare Porsche 964 Leichtbau, Scarcer Than Most Hypercars, Prepares for $1 Million Auction
Rollin' with the Underdogs: The Unassuming Porsche 964 Carrera 4 Leichtbau
(Warning: Coarse Language Ahead)
You may have drooled over the sight of a flashy supercar or tipped your cap to a limited-edition hypercar, but the real diamonds in the rough are those that don't fit the mold. Case in point: that unassuming white Porsche 964 Carrera 4 Leichtbau headed to Gooding Christie's Pebble Beach auction in August. Sure, it seems like just another clean '90s 911 on the surface, but to Porsche enthusiasts, it's one of the rarest and most badass 911s ever crafted - one of only 22 examples that revolutionized Porsche's approach to road and race cars.
Reigniting the Racing Spark: Jürgen Barth & the Unrealized Series
The story of the Leichtbau starts with Jürgen Barth, a Le Mans-winning driver who ran Porsche's Customer Racing Department in the early '90s. As the head honcho of Weissach's motorsport division, Barth dreamt of creating a racing series for the brand new 964 Carrera 4. What he envisioned was something akin to a 964 RS with all-wheel drive - a beast that could showcase Porsche's sophisticated drivetrain technology on both the road and rally stages.
The timing was right. Porsche's Carrera Cup was morphing from its 944 Turbo roots into what would eventually become the world's most prestigious single-make racing series. The 964 platform, with its all-wheel-drive system borrowed from the 953 Paris-Dakar rally car, seemed like the perfect launchpad for the next evolution.
Throwing Weight and Making History: Engineered for Awesomeness
To create the Leichtbau (think "lightweight"), Porsche's racing workshop abandoned typical weight-saving measures and went all-in. Sure, they ripped out the carpet, sound deadening, and luxury features, but that was just the appetizer. They replaced the doors and hood with aluminum pieces, the engine lid became fiberglass, and the side windows were swapped for sliding Plexiglas panels.
The end result? A car that weighed just 2,414 pounds, which is 330 pounds lighter than even the track-focused 964 Carrera RS and nearly 850 pounds less than a standard Carrera 4. To put that in perspective, this 1990 Porsche weighs less than most modern Miatas.
Transfer of Tech Tactics: Showcasing Porsche's AWD Magic
The adjustable, electronically-regulated all-wheel-drive system came directly from the 953 Paris-Dakar rally car, allowing drivers to manually adjust torque distribution between all four wheels. The suspension was lifted from the 964 Cup car and dropped by an inch, while the adjustable rear spoiler was fixed in position for maximum downforce.
Under the stripped cabin sat the same 3.6-liter dual-ignition flat-six found in the 964 RS, but with catalytic converters and mufflers deleted for an extra 5 ponies, bringing total output to 265 horsepower. Power flowed through a close-ratio five-speed manual, providing dramatic exhaust notes for speed enthusiasts.
A Time Machine in the Garage: One Hell of a Rare Find
The example going to auction is chassis number 004, dressed in Grand Prix White with a black interior pared down to the bare necessities. With just 312 miles on the odometer, it's practically a brand-new car from 1990. The cabin features Recaro bucket seats, a roll cage, and that's about it.
The rarity is off the charts. Even though the 964 generation is already the least-produced 911 variant with 63,762 examples built across all models, the Leichtbahn represents only 22 of those cars. Finding one with such low mileage is like stumbling upon an automotive myth.
The Never-Was Racing Series
Ironically, the racing series that these cars were designed to populate never took off. After cranking out 22 development cars, Porsche canned the Leichtbau program, making these vehicles forever orphaned prototypes. In some ways, this makes them even more desirable.
The Carrera Cup eventually morphed into a global phenomenon, but it evolved using different cars and different technology, while the Leichtbahn cars became footnotes in Porsche's storied history.

David Brynan, senior specialist at Gooding Christie's, had this to say, "The Carrera 4 Leichtbau is one of the most rare, interesting, and technically sophisticated 964 models-and is among the last 911s that were entirely hand built in Porsche's legendary racing workshop, Werk I."
