The Duesenberg Model J ‘Sweep Panel’ Dual-Cowl Phaeton by LeBaron stands as a testament to the opulence and engineering prowess of the late 1920s and early 1930s. Introduced in 1928, the Model J was designed to rival the world’s most luxurious automobiles, and the ‘Sweep Panel’ Dual-Cowl Phaeton exemplified this ambition.

Crafted by LeBaron, the ‘Sweep Panel’ Dual-Cowl Phaeton features a distinctive inset panel that begins at the radiator cap, broadens toward the cowl, and sweeps into the door, terminating in a reverse curve. This elegant design, attributed to Ralph Roberts of LeBaron, imparts a sense of motion even when the vehicle is stationary. The dual-cowl configuration includes a second windshield for rear passengers, enhancing both aesthetics and comfort.

At the heart of the Model J lies a formidable 420 cubic inch (6.9-liter) straight-eight engine, producing 265 horsepower. This powerplant enables the vehicle to achieve a top speed of 116 mph (187 km/h), with 89 mph (143 km/h) attainable in second gear. Such performance was unparalleled at the time, solidifying the Model J’s reputation as both a luxury and performance leader.

The Model J’s chassis was available in two wheelbase lengths: a standard 142.5 inches (3.62 meters) and a longer 153.5 inches (3.90 meters). The dashboard was equipped with mechanically timed lights to remind the driver of maintenance tasks, such as oil changes and battery inspections. The vehicle’s interior was customizable to the owner’s specifications, often featuring opulent materials and intricate detailing.

The ‘Sweep Panel’ Dual-Cowl Phaeton was among the initial body styles offered for the Model J, with LeBaron’s design setting a precedent for elegance and sophistication. In 1931, Duesenberg’s in-house coachbuilder, LaGrande, introduced a similar design, reflecting the enduring popularity of the ‘Sweep Panel’ motif.

Notably, chassis no. 2336 is recognized as the only long-wheelbase ‘Sweep Panel’ Dual-Cowl Phaeton ever built, underscoring its unique status among Duesenberg enthusiasts.

The ‘Sweep Panel’ design is a hallmark of the Model J, showcasing LeBaron’s innovative approach to automotive aesthetics.
