The Hupp Motor Car Company was founded by Robert and Louis Hupp in 1908. Throughout their 32 years of operation they produced a wide variety of cars. Hupmobile’s early cars appealed more to the entry-level market, competing along the lines of the Ford Model T. In the mid-1920s Hupmobile decided to focus its product toward more wealthy consumers with the introduction of a new eight-cylinder engine. For the 1925 model year, Hupmobile’s products could be purchased either with the well-known and proven four-cylinder motor or the upscale and significantly more powerful L-head inline eight-cylinder engine. This motor could churn up higher RPMs than others at the time, generating as much as 60 horsepower and performed above expectations. There was a substantial price difference between the two cars, with the eight-cylinder models costing around $700 more than their four-cylinder counterparts. Four-wheel hydraulic brakes and balloon tires were also available on the higher priced Hupmobiles.

This 1925 Hupmobile E-1 Boattail Roadster, offered from The Roaring Twenties Museum Collection, is a brilliant example of how the company went about establishing itself within a more affluent upscale clientele. The exterior, elegantly painted in tan, light green, and black, immediately draws attention. A black soft top, red interior, and light tan artillery wheels give this Hupmobile even more of an eye-catching look. The history of this car is just as vibrant and alluring as its color scheme. Delivered new in 1925 to a bootlegger in Fairmont, West Virginia, it is rumored to be just one of just eight produced in this body style. After running into some health problems, the bootlegger was forced to rapidly depart West Virginia, after which his car fell into disrepair. The second and final owner of the car purchased it in 1962, taking the car home in three separate trips. After two years of lengthy restoration work, the sporty little Hupmobile was once again ready for the open road. This particular E-1 Roadster is one of just three still in existence today.

Despite being mass-produced in their day, Hupmobiles are very uncommon sights on the road and at events, adding further value to this tastefully restored car. Bound to turn heads wherever it is driven, this 1925 E-1 Boattail Roadster is a truly unique and rare find.
