The Art of Automotive Balance

Born of invention and fueled by passion, these best works almost always exhibit an ideal balance that is easily recognized. While not everyone will understand or even appreciate what it is that defines the success of a particular endeavor, those who do know exactly what has been accomplished. This is how appreciation is fueled and winners are created.

The Birth of Ferrambo

As crazy as it may seem at first glance, there’s no questioning the seriousness of Ferrambo. Every element of its existence was built with a goal in mind, not just of winning the Ridler award at the Detroit Autorama, which it did handily, but of creating what its builders believe is a perfect union between divergent design philosophies. While Ferraris are beautifully sculpted extensions of a proud racing heritage, Nash Ramblers were conceived as inexpensive, economical transportation for the masses. So, how did two vehicles at the polar extremes of automotive expression end up united in this landmark effort?

The Initial Concept

Four years ago, Tim Divers met with his friend and longtime customer Mike Warn to discuss Warn’s next project. At that time, neither really had a handle on what that car might be. Warn began contemplating the possibilities of a ’60 American Rambler wagon sitting in Divers Street Rods in Startup, Washington. First came questions about the overall look and appeal, followed by much discussion about possible chassis concepts, before the weighty conversation led to the all-important topic of the drivetrain. As they reached a proposed mid-engine layout for this wagon, they understood that such an effort would require a visually stimulating power source. Various engines were considered but never seriously considered until fellow rodder Craig Lang rolled up in his Ferrari 360 Modena. This immediately sparked Warn’s creativity, leading to the unthinkable question: “What if we fitted the best elements of a Ferrari 360 into the Rambler wagon?”

The Creation of Ferrambo

And so came the concept for Ferrambo, a car that melds vehicles built over four decades apart into one imaginative and exceptionally well-finished creation. On its maiden showing, it earned the top award at what many consider to be the most prestigious indoor rodding show in existence. While winning this honor was never the intention or even a consideration at the time, all involved began to wonder, “What if?” Might they actually have a chance to join an elite few and take home the Ridler with such an unusual conglomeration of technology?

The Builders Behind the Dream

With plans set and the Rambler already in hand, the time came to locate the mid-engine Ferrari. Soon, one was found in California, a victim of a prom-night spin that left both passengers untouched but heavily damaged the car’s nose and tail sections. The mechanical elements remained pristine and ready to drop into the wagon, figuratively speaking.

The Creative Process

Many have praised the meticulous creativity displayed in this unique effort, from the overall design to various custom-built components. Others fail to appreciate the blending of some of the most advanced mechanicals with, arguably, one of the most uninspiring automobiles ever built. Yet, this is what makes Ferrambo so special; it’s the very dichotomy that underscores its appeal. There’s a special discovery for anyone who takes the time to look beneath the subdued exterior to see all that shines below. Even the most skilled craftsmen will have a hard time identifying the broad strokes, let alone the finer points, as the integration among all the different elements is seamless.

The Interior: A Blend of Tradition and Innovation

From the seating position, the Rambler dash is very much the same, yet the Ferrari lineage is unmistakable. Saffron Fine Scottish leather borders rich PPG paint between details of another kind. The seats themselves, shaped from sheet aluminum, look transplanted from another time. This craftsmanship extends to the reveals surrounding the seats, the console, the door panels, and many unseen pieces. While the craftsmen in Maranello might find it hard to fathom the rationale behind this effort, they would doubtless appreciate its execution.

A Fusion of Function and Aesthetics

Beyond luxury, every aspect of the interior was built with functional considerations in mind. Retaining the instrument alone was pivotal to maintaining the origins of this Nash. Now, an artfully labeled and lighted tachometer replaced the speedo, with a MoTeC digital data-logger hidden beneath an adjoining leather panel to display other important functions. This system records cornering, acceleration, stopping loads, and other trip information.

Custom Details and Finishes

The steering wheel, built in the classic tradition, features an aluminum framework surrounded by laminated teak. It mimics a wheel one might see in a Lusso or vintage Ferrari, but instead of a prancing horse, the horn displays a perforated steel centerpiece. This material is also used on the shift knob, rear pillar vents, and other details, molded to the contours they accent. A wealth of specially fabricated pedals, handles, trim pieces, and other fine details create an environment that aligns with every Ferrari that has rolled out of Maranello and Modena since 1946.

A Unique Tribute to Ferrari

While some may consider this type of transformation bordering on blasphemous, the Ferrari 360 Modena components used in creating Ferrambo came from a heavily damaged unibody car far beyond repair. So, what we have here is a collection of Ferrari parts that, rather than being discarded, have become part of something truly unique and very cool.

The Legacy of Ferrambo

Whether understood or not, Ferrambo has shown how simple concepts can be born, emerging as amazing expressions of creativity that remain pure and uncontained. This remarkable fusion of seemingly incompatible elements has resulted in a car that stands as a testament to the power of imagination and the artistry of automotive design.

RAMBLE ON

While Kenosha, Wisconsin, may not seem geographically pivotal to this project, it’s where two key elements took shape in 1960. Just about the time American Motors rolled this Rambler wagon off its assembly line there, Mrs. Divers was completing a project just up the road, one she lovingly named Timmy. While decades passed before this alignment was realized, the wheels of change were already turning as skills so readily adapted decades later were first learned, perfected and applied to crafting yachts, cars and other endeavors. In time, Divers Street Rods opened, building notable cars and occasionally buying one, including a homely American Rambler wagon. While he couldn’t have imagined it at the time, that car would become the foundation for Divers’ most audacious challenge to date, a car that will forever be known as Ferrambo. Four years and thousands of hours in the making, the Kenosha connection finally came full circle through the vision and skills applied at Divers Street Rods.

360 MODENA SPIN

Centered on V-12s since day one, Ferrari’s most popular plentiful cars, the mid-engine 360 Modena and newer 430s, are well motivated with stout V-8s that actually bolster Ferrari’s perpetual performance image. Sadly, not everyone with access to these cars has developed skills needed to handle these beauties, including one testosterone-toting teenager on prom night. Believing his dad’s Italian Stallion was forever glued to the road, reality set in when a 15mph corner bested the teen’s limitations, tossing the once-flawless 360 into Neverland. Although the passengers walked away, the Ferrari wasn’t so lucky and was eventually written off. As a result of these events, owner Mike Warn and Tim Divers were empowered with the wherewithal to move ahead, as much of the donor Ferrari was still intact. While enthusiasts on both sides of the corporate fence might question the logic behind this effort, we’re again reminded that logic has little to do with super rodding.

LUSSO INTERPRETATION

One of the biggest challenges Ferrambo presented was altering the body contours in ways that would retain the flavor of the Rambler, rather than obscuring it, while melding its contours with those of past Ferrari greats such as the beautiful ’64 Ferrari Lusso. To achieve this goal, countless changes were made to the body, including the creation of entirely new doorjambs and driprails, revised fender openings and even that Lusso nose. This classic styling was created by extending the fenders around the headlights, creating space for the running lights and fabricating an egg-crate grille that fits precisely within an opening in the nose. The hood, too, follows familiar contours, rising beautifully between the fenders on specially made hinges that are as beautiful as their surroundings. But rather than welding in the door-skin seams along with other areas, most details were finished off old school and leaded in to reduce the chances of warping the metal.

CHASSIS CHALLENGES

Rarely has anyone united the best elements of these two divergent vehicles so well, and while some will ask why, most gearheads are likely to wonder how this amazing car came together. Featuring unibody construction originally, new additional framework was devised for this Rambler, creating even more rigidity once the two elements are joined as a single unit. When necessary, a special engine and transaxle cradle integrated within the rear of the chassis can be dropped down for servicing—and all in a mere 1.5 hours—as working within the tight confines of the wagon is nearly impossible. Ensuring this chassis lives up to expectations, special jigs precisely transfer 360 Modena suspension geometry to Ferrambo, while another fixture duplicated the Ferrari’s front A-arms in chromoly. Combined with double-adjustable coilover shocks, sway bars, special wheels and sticky rubber, the capability of this chassis in on a par with the exquisite detailing and lustrous finishes complementing this truly exceptional vehicle.

WHEEL VISION

With so many companies milling wheels today, it came as a surprise when Divers opted for special wheels machined specifically for Ferrambo. Then again, this was the only way Warn and Divers could obtain the design they envisioned, since nothing like them was available. Based upon illustrations, modeling foam was used to shape the spokes and determine if the design translated from two to three dimensions. Once finalized, SolidWorks software was employed by Willis and Mike at Quality On Time Machining to bring the 18×8.5s and 20x10s into reality. No easy task, at least 24 hours was spent milling each of the 6062 T651 alloy wheel centers, even before the center splines were cut, turning a 90-pound billet into a 10.5-pound front wheel center. Right- and left-hand threaded spindle nuts were then precision milled, as this interface is of critical dimensions. Finally, the centers were painted, fastened to outer rims, fitted with 225/35s and 295/30s, balanced and readied to roll.

RADICAL ROTORS

While Divers Street Rods could have used original Ferrari 360 brakes or opted for any of several aftermarket systems, it was decided to scratch-build rotors for Ferrambo and fit them with 360 Modena calipers. This involved spin-casting 12-inch rotors from Functionally Gradient AI/SiCp metal-composite brake rotor material. These employ a blend of aluminum alloy and silicone carbide particles ranging from 20 to 50 percent volume inside-to-outside of the rotor friction ring in a radial direction. Rotors formed in this way offer exceptional strength in terms of increased fracture toughness needed to withstand braking torque mechanically transferred to the center hat section and hub. Benefiting from a thermal conductivity five times greater than iron rotors, they also weigh 60 percent less than equivalent ferrous-based rotors, and they better manage internal stresses caused by differential heating and related material expansion. Fast or slow, hot or not, these brakes live up to Ferrari’s four-piston front and two-piston rear calipers.

PRANCING POWER

Developing 400 hp at a tingling 8,500 rpm and 275 lb-ft of torque at 4,750 rpm, the Ferrari 360 3.6-liter five-valve V-8 once displayed beneath the rear window of a 360 Modena was just a starting point. Stripped of all external hardware and its electronics, two detail fanatics spent two long months carefully smoothing every square millimeter of the block, cylinder heads and related componentry. Next, these same surfaces were prepped for paint and shot with PPG’s DBC 33897 Fine Metallic, a warm hue looking as if it was created just for this car, even though it’s available to everyone. Adorned with exquisite detailing in chrome and polished aluminum, carbon-fiber touches and other fine details, this “prancing horsepower” has been elevated to a stature that its counterparts can’t even counter. And yet for all its technological advances, this compact Italian V-8 is relatively tame, starting easily, idling smoothly and eagerly revving to the redline without so much as whine. It sounds good, too.

BREATHE EASILY

Like a glistening jewelry box on wheels, the engine compartment of this wagon displays exceptional workmanship beyond anything seen in today’s world-class sports cars. Every component is specifically built, from the engine cradle and flowing inner body panels to the clever induction system that draws in fresh air from the rear pillars. Lengthy tubes extend between the intake manifold and the rear pillars, where forward-facing, mesh-covered openings are concealed beneath the glass, until the engine is started. Once fired, the rear side windows electrically retract in back, exposing grilled vents that are essential to airflow, gobbling it in as air passes by. Here again, beyond all the innovations are the many fine details highlighted with flawless red paint, exquisite detailing and great care by the crew at Divers Street Rods. While many cars of this caliber prove to be pretenders, know that Ferrambo is quite capable of backing up its Italian sports car perceptions, and with a drivetrain that is capable of pushing this Rambler to limits never conceived for such a car.

EXHAUSTING EFFORT

Every exhaust system they built before was training for the complex ventilators Divers formed for this car. The Ferrari-based headers alone required 190 hours to fabricate from 304 stainless steel tubing, as tight confines dictated a compact design, tucked close to the engine, like the original Ferrari exhaust. The rest of the system, from exhaust flange to the tips, added another 210 hours to this exhausting effort. Here again, every aspect of this fitment was crafted with the utmost care, from the hangers to the welds. Out of sight, tucked away within the rear portion of the chassis, the exhaust tips are unique, as they actually add backpressure needed to keep the engine management system happy. This “boxed” arrangement also disperses exhaust energy with an intriguing note, raising little dust despite being pointed earthward. Polished to a mirrored finish, this exhaust system is, like many aspects of Ferrambo, a flawless execution of applied passion and skill.

TECHNICAL TAKE

The Bosch ME 7.3 electronic management system that once managed Ferrari’s 360 Modena has been replaced with a specially developed MoTeC electronic control system fitted in its place. Integrated within a custom wiring system engineered by Brian Macy at Horsepower Connections, these new electronics empower every aspect of engine operation, including the effective drive-by-wire gas pedal, integrating ASR traction control and other Ferrari-derived advances. Elsewhere, Divers employed clever technologies in scratch-building the LED taillight lenses, the perforated stainless screens accenting the shifter knob, air intake vents and other details and adapting a number of different electronic devices hidden throughout this wagon. And then there were the many challenges of uniting the front-mounted cooling system, the lengthy shift linkage, modified rack-and-pinion steering, powerful braking and other mechanical elements that have been packed within this wagon. Whatever your preference, there’s no questioning the skill and expertise Ferrambo displays, as it’s all in line with the exotic nature of the advanced Ferrari drivetrain.

INSIDE TRADING

While other aspects of Ferrambo certainly attract attention, it’s the interior that gets the most, and no wonder. The seats, for instance, were built from 0.062-inch 5052 aluminum panels and then thinly padded before Scott Divers fitted them with Saffron Fine Scottish leather, the same material covering everything but the red, including the floors and even the show stage. While Nick Lambert’s beautifully adorned tachometer replaces the speedo, the accent panel center-right now folds down, revealing a MoTeC M48 Data Logger that returns both vital and visceral information. In keeping with the vintage Ferrari theme, teak was fitted, shaped and smoothed around an aluminum steering wheel frame centered with a specially formed screen for the horn button. A beautiful sculpture to be sure, Enzo himself would approve of this amazing craftsmanship, as well as a highly capable audio system centered on that exquisite Ferrari V-8 howl. It provides all the entertainment anyone could ask for.

SEVEN LETTERS

As if from two ends of the automotive universe, Ferraris and Ramblers seemingly share nothing in common in terms of design or function, other than they are both transportation. One is suited to the extremes of exceptional performance and acknowledged finish; the other is relegated to a life of mediocrity. It’s as if they’re from two different worlds, and they are—at least until now. As this project took shape and measurements were made to establish a baseline for all that was to come, a number of similarities quickly became evident, including the fact that these two unibody cars share a 102-inch wheelbase! While the wagon once had a four-cylinder engine in front, and hauled four or possibly five passengers, its new 360 mid-engine layout now matches the Ferrari’s original occupancy limit of two. Add to this the myriad highlights, accented by the Ferrari Red paint, the rich tan leather, the beautiful chrome and polished aluminum, and there’s no ignoring the commonality this unusual creation has wrought, including the fact that there are seven letters in both Ferrari and Rambler.
