1927 Hupmobile Series A: A Capable Six from Detroit

The 1927 Hupmobile Series A brought six-cylinder power and substantial-car comfort to drivers who wanted something more refined than a basic economy car. Built by the Hupp Motor Car Company in Detroit, Michigan, it came from a manufacturer that had earned a strong reputation during the early years of American motoring.

Hupp Motor Car Company was founded by Robert Craig Hupp, an engineer and entrepreneur who had previously worked in the emerging auto industry. The company’s first cars appeared in 1909, and Hupmobiles soon became known as practical, well-engineered machines. By 1927, the Series A sat in a competitive market crowded with established makers such as Buick, Studebaker, and Chevrolet. Its appeal was a balance of six-cylinder smoothness, traditional styling, and a range of body choices.

One intriguing detail is that “Series A” identifies a model range rather than one single body design. A Series A might be an open touring car, a coupe, or a closed sedan, so surviving examples can look quite different from one another while sharing the same basic mechanical character.

Classic Lines and Period Comfort

The Series A wore the upright proportions typical of a late-1920s American automobile. Its tall radiator, long hood, separate fenders, exposed running boards, and spare tire gave it a purposeful profile. Open models emphasized the long sweep from hood to passenger compartment, while sedans and coupes looked more formal, with high roofs and enclosed cabins. Details such as bright radiator trim, lamps, and hubcaps added polish without disguising the car’s sturdy, practical design.

Inside, the experience depended on the body style and original equipment. Closed cars generally used durable upholstery, often cloth, while open models could have more weather-resistant trim and leather seating. Wood framing and trim were common in coachbuilt bodies of the era, and the cabin prioritized function: a large steering wheel, clear instruments, straightforward controls, and a broad view over the hood. Compared with a modern car, it was sparse, but in its day it offered real comfort for longer trips.

Factory paint choices varied by body and production year. Period cars were commonly finished in dark, formal colors such as black, deep blue, maroon, or green, sometimes paired with contrasting trim. Exact combinations depended on the catalog and buyer’s order, so a restored car’s current color should not automatically be taken as its original specification.

Series A body offerings included several of the era’s familiar formats, such as touring cars, roadsters, coupes, and sedans. Availability could differ by model year and market. The touring car, with its open cabin and folding top, is among the most visually evocative versions today. Sedans and coupes were the more weather-protected choices for owners who used their Hupmobile year-round.

Six-Cylinder Engineering in Context

The Series A’s appeal rested in part on its six-cylinder engine. Published specifications commonly identify a roughly 228-cubic-inch (3.7-liter) inline six producing about 60 horsepower, though figures can vary among reference sources and individual cars. A three-speed manual transmission was typical. Four-wheel mechanical brakes were an important period feature, giving the driver braking at all four wheels rather than relying only on rear brakes.

Those features made the Hupmobile a well-rounded car, not a radical experiment. Its significance lies in how it reflected the automotive industry’s shift toward smoother, more capable six-cylinder cars for ordinary buyers. Hupmobile competed by offering a substantial, well-equipped automobile from an independent manufacturer, rather than by chasing the cheapest possible price.

The Series A also represents a moment when the American car was becoming a more dependable tool for everyday travel. Enclosed bodies, electric starting and lighting, and improved braking were increasingly expected by buyers. The Hupmobile combined these conveniences with the traditional chassis-and-body construction of the period. It did not transform automotive design, but it illustrates how quickly comfort and safety equipment were becoming part of mainstream motoring.

Road Manners and Period Performance

A healthy Series A is generally described as a car capable of roughly 55 to 65 mph, depending on gearing, condition, body style, tire choice, and how accurately the speedometer reads. Reliable factory acceleration figures are difficult to establish. A modern estimate for 0 to 60 mph would be around 30 seconds or longer, and some examples may not comfortably reach 60 mph at all. These are estimates, not period test results.

On a smooth road, the Hupmobile’s long wheelbase and substantial chassis deliver the steady, deliberate ride expected of a 1920s touring car. Broken pavement is a different story. Its suspension can soften larger bumps, but narrow tires, solid axles, and limited damping mean the body still moves around over rough surfaces. On winding roads, the driver needs to plan ahead: steering is slower and heavier than in a modern car, and braking distances are much longer.

Behind the wheel, the engine’s sound is a measured mechanical hum rather than a modern high-revving roar. The driver works a manual gearbox, manages a substantial steering wheel, and stays attentive to the road. That direct involvement is part of the charm, but it also means the Series A is best enjoyed at a relaxed pace, with room to brake and time to appreciate the scenery.

Living with a Hupmobile Today

In 1927, a Series A could serve as family transport, a touring car, or a comfortable conveyance for business and social visits. Today, most examples are used as show cars, parade vehicles, museum pieces, or occasional weekend drivers. Regular use is possible, but it calls for realistic expectations about speed, traffic, and weather protection.

Maintenance is straightforward in principle, especially for an owner familiar with prewar cars. The mechanical systems are largely accessible, and a competent vintage-car mechanic can service the engine, brakes, clutch, and driveline using traditional methods. The challenge is often not complexity but parts supply. Wear items and commonly shared components may be found through specialist suppliers or the vintage-car community, while model-specific trim, body panels, and interior pieces can take time to locate or reproduce.

Reliability depends heavily on restoration quality and regular upkeep. Before driving a survivor, an owner should inspect the braking system, tires, steering, fuel lines, cooling system, and lubrication points. Mechanical brakes require careful adjustment, and old tires can be unsafe even when their tread appears adequate. A well-maintained car can be rewarding, but it should not be treated like a modern daily driver.

Hupmobile Trivia and Common Criticisms

The Hupmobile name comes from founder Robert Craig Hupp, whose career reflected the restless, inventive character of the early auto industry. He left the company he had helped create, while Hupp Motor Car Company continued to build cars under his name. The firm remained an independent automaker in a business increasingly dominated by very large manufacturers.

No widely documented speed, endurance, or sales record is specifically associated with the 1927 Series A. Its significance is more representative than record-breaking: it shows what a well-equipped American six-cylinder car could offer during the decade’s rapid expansion of automobile ownership.

Common criticisms are the same ones owners make of many cars from the period. The Series A is slow by modern standards, requires frequent attention compared with a contemporary vehicle, and offers limited protection from bad weather in open body styles. Parts availability can also complicate restoration. For collectors, those drawbacks are balanced by its engaging mechanical simplicity, handsome proportions, and connection to a notable independent marque.

Rarity, Values, and Collector Appeal

There is no dependable, widely accepted production total for the 1927 Series A alone. Hupmobile production records are not always broken down by individual series and body style. As a best estimate, Series A production across its model run may have reached several tens of thousands, perhaps roughly 20,000 to 40,000 cars, but that range is speculative rather than a verified factory figure. The number surviving today is much smaller, and particular body styles or unusually original cars can be difficult to find.

As a broad 2026 estimate in the U.S. market, a project car might sell for around $5,000 to $15,000, depending on completeness and rust. A usable driver or older restoration could fall in the $15,000 to $35,000 range. A high-quality restoration, rare body style, or especially original example could bring roughly $35,000 to $60,000 or more. Condition, provenance, mechanical health, and the quality of the restoration matter more than a single published price guide figure.

Values for prewar cars tend to move gradually rather than follow the sharp swings seen in newer collector markets. Well-documented, correctly restored examples are likely to hold their appeal, while incomplete cars can be costly to bring back because specialized body and trim work adds up. The Series A’s market is relatively narrow, so sale prices can vary considerably from one auction or private transaction to another.

Why the 1927 Series A Still Matters

The 1927 Hupmobile Series A was a capable six-cylinder automobile from a respected Detroit manufacturer. Its upright styling, practical body choices, period engineering, and engaging driving experience make it a compelling representative of late-1920s motoring. It was not a record setter, but it offered the comfort and mechanical sophistication buyers increasingly expected from a full-size American car.

For today’s enthusiast, a Series A is more than a handsome antique. It is a rolling reminder of the independent automakers that helped shape the early industry. At a careful pace, with its engine ticking beneath the long hood, the Hupmobile makes its case the old-fashioned way: through character, craftsmanship, and a story worth keeping on the road.
