Vehicle Description
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 sedans-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.
