1936 HOFFMAN X-8
The 1936 Hoffman X-8 prototype represents a remarkable chapter in automotive history, a vision of modern engineering and design that defied conventions of its era. Conceived and built by engineer and inventor Rod Hoffman, the X-8 reflects Hoffman’s bold belief that rear-engine cars would lead the future of the industry. Crafted with advanced technology and a streamlined design, this unique prototype is not only a marvel of pre-war engineering but also a running, driving testament to Hoffman’s forward-thinking ideas.

Unlike any other vehicle of its time, the Hoffman X-8 embodies a groundbreaking rear-engine layout with a frameless all-steel unitized body construction, a true rarity in the mid-1930s. From its proportions alone—lower, narrower, and more compact than typical 1930s sed... ans—the X-8 stands apart. Hoffman envisioned a rear-engine layout as the solution for ideal weight distribution, improved braking, enhanced passenger comfort, and minimized engine noise. In a letter to Automotive Industries magazine in 1933, Hoffman outlined the benefits of such a design, noting how it would improve road traction, maximize braking efficiency, and offer lighter steering and improved headroom, all while keeping noise, heat, and vibration far from the cabin. His prototype, completed in 1935, became the physical manifestation of these principles.

At the core of this unique vehicle is Hoffman’s revolutionary X-8 engine. This 168.4 cubic inch powerplant, with four pairs of cylinders in an “X” configuration, is the only known example of its kind in existence. Capable of generating an estimated 75 to 90 horsepower, this engine layout—positioned just ahead of the transaxle—allowed for balanced weight distribution and stable handling. The narrow-angle configuration and a single two-barrel carburetor fed all eight cylinders, delivering an effortless and surprisingly responsive driving experience. Given its unconventional setup, the X-8 also features an ingeniously arranged drivetrain and an advanced suspension system designed for an unmatched blend of comfort and stability.

The X-8 prototype’s unitized body was constructed by the Edward G. Budd Manufacturing Company of Philadelphia, a pioneering firm in steel body design known for its innovative work in the automotive and railway industries. Budd’s work on the X-8 included a honeycomb-reinforced floor and built-in perimeter strength members, features that were decades ahead of their time. The streamlined bodywork is distinctly practical yet aesthetically advanced, with an iconic faux grille, seamlessly integrated headlights, a “vee’d” windshield, and sleek fenders that flow gracefully into the front doors—design elements that would not appear in regular American cars until the 1940s. Additionally, the absence of running boards, the sloping fastback profile, and rear "butterfly wing" panels for engine cooling all contribute to a thoroughly modern aesthetic.

Inside, the X-8 prototype provides seating for six passengers, a rare feat for a car so low and narrow. The flat floor, unobstructed by a transmission hump, allows ample foot space and headroom for all occupants. The interior, carefully preserved, is clean and correct, featuring an innovative articulated gearshift lever that mounts on the dash, enabling traditional three-speed shifting without impeding the front passenger’s legroom. The uncluttered dash includes a basic three-spoke steering wheel and tidy, circular gauges centered for easy visibility. These elements underscore Hoffman’s dedication to creating a spacious, comfortable cabin without compromising the vehicle’s unique layout.

The X-8’s performance has been praised for its power and agility. In a 1974 test drive by noted automotive writer Michael Lamm, the X-8 prototype showed impressive handling and responsiveness, with Lamm noting that it “steps out smartly” in lower gears and “feels amply potent at any rpm.” He further remarked on its “extremely quiet” operation and its secure, stable handling, with minimal understeer and no tendency to oversteer, a common challenge for rear-engine vehicles of the period.

Today, more than 85 years since its creation, the Hoffman X-8 remains in excellent condition, both mechanically and aesthetically. The exterior presents extremely well, having been sympathetically restored by its previous owner, and continues to showcase the precision craftsmanship of Budd Manufacturing. The interior is beautifully preserved, with the unique transmission shifter and cabin layout reflecting Hoffman’s attention to detail and dedication to innovation.

As a one-off concept, the Hoffman X-8 is the only known example of an operable X-8 engine vehicle, making it a truly exceptional collector’s piece. Its history, engineering, and preservation make it a testament to Hoffman’s legacy as a visionary in automotive design and innovation. The Hoffman X-8 offers a rare opportunity to own a singular piece of automotive history that embodies the ingenuity, elegance, and pioneering spirit of its era.
