The Nash 600 is an automobile manufactured by the Nash-Kelvinator Corporation of Kenosha, Wisconsin, for the 1941 through 1949 model years, after which the car was renamed the Nash Statesman.

The Nash 600 was the first mass-produced unibody-constructed car in the United States and the era's most advanced domestic car design and construction.[1] The "600" name comes from the car's advertised ability to go Script error: No such module "convert". on one tank of gasoline.

The Nash 600 was positioned in the low-priced market segment.[2] It was effectively the replacement for Nash's LaFayette line, which was discontinued after 1940.[3]

Innovations

Under the leadership of George W. Mason, president of the newly merged Nash-Kelvinator Corporation, a strategic objective was set: redefine Nash's image in the automotive marketplace.[3] The Nash 600, introduced for the 1941 model year was the result of this vision for future cars.[4] Nash relied on Theodore (Ted) Ulrich, who worked at the Budd Company, for the innovations in automobile body manufacturing.[5] Ulrich had previously worked with Nash's chief of engineering, Nils Erik Wahlberg, in the development of the all-new and radically styled 1949 Airflyte models.[6]

The car's design and styling heralded a new era for the brand.[3] The Nash 600 was a pioneer, boasting several groundbreaking innovations that distinguished it from its contemporaries.[5]

The most significant innovation of the Nash 600 was its distinction as the first mass-produced automobile in the United States with unibody (unitized body/frame) construction techniques.[7] Unlike the traditional body-on-frame method, where a car body is bolted onto a separate chassis frame, the Nash 600 featured a design where the car body and frame were welded together as a single, integral unit.[8] This revolutionary construction offered numerous advantages that Nash effectively leveraged in its marketing.[9]

The elimination of a separate heavy frame resulted in a substantial weight reduction of approximately Script error: No such module "convert". compared to conventionally built cars.[2] The single, welded unit created a more rigid structure, contributing to improved handling and stability. The integrated construction led to a quieter and smoother ride by reducing rattles and squeaks commonly associated with separate body and frame designs.

This pioneering body design, while offering significant manufacturing and performance benefits, it required Nash to invest of $7.5 million for the design and tooling in Nash's Kenosha factory, a substantial amount for the small independent automaker.[5] Furthermore, it required the development of innovative techniques for collision repairs, including a new portable body and frame puller tool that quickly gained international acceptance.[10][3]

Complementing its revolutionary body structure, the Nash 600 incorporated a suspension system that was advanced for its time.[3] It featured coil spring suspension at all four wheels and a fully independent front suspension. This combination contributed to the car's notably comfortable ride quality and improved handling characteristics, distinguishing it within its class.

The "600" designation was a marketing strategy reinforcing the automaker's ambitious claim: the car's ability to travel Script error: No such module "convert". with a full gasoline tank. This range was a direct result of the car's exceptional fuel economy, which ranged from Script error: No such module "convert"., combined with a Script error: No such module "convert". fuel tank.[11] Its efficiency was further enhanced by the significantly lower weight compared to similar-sized vehicles.

Beyond these core innovations, the Nash 600 also featured spacious and well-appointed interiors for its segment, enhancing its appeal as a modern and practical family car.[3][5]

1941: Introduction

Launched for the 1941 model year, the "Nash Ambassador 600" was a groundbreaking for the automaker. The Nash 600 offered a versatile range of four body versions, all with a streamlined aesthetic that set them apart from the competition. The four-door Slipstream (fastback) sedan was aerodynamic featuring a smooth, flowing roofline that integrated into the rear, with no protruding lights, running boards, or exposed door hinges, contributing to a modern appearance. The four-door Sedan with built-in trunk (notchback) was more conventional offered practicality with a distinct trunk compartment at the rear. The two-door Coupe Brougham featured full-width front and rear seating, emphasizing passenger comfort. The two-door Business Coupe was designed for utility with a spacious rear deck cargo compartment for extra storage capacity.[12]

The 1941 Nash 600 featured a Script error: No such module "convert". L-head straight-six engine. This engine, known for its fuel economy, produced Template:Cvt at 3,600 rpm.[12][13] A three-speed manual gearbox had an electric overdrive system to enhance efficiency.[14] The car also featured coil springs on all four wheels, contributing to a smooth and comfortable ride. A tight Script error: No such module "convert". turning circle made it agile for its size.

The Nash 600's fuel efficiency was demonstrated in a 1941 event jointly sponsored by the American Automobile Association (AAA) and Gilmore Oil, a California-based petroleum company. Similar to the Mobilgas Economy Run, this competition saw the new Nash 600 deliver an Script error: No such module "convert". on regular roads, making it "Best in Class" winner.[15]

Overall production for the 1941 calendar year reached 80,428 units, securing Nash slightly more than 2% of the domestic market share.[3]

1942: Civilian production ends

For the 1942 model year, the Ambassador 600 continued as one of three distinct series offered by Nash.[16] Stylistically, the 1942 models received a refreshed front end, characterized by prominent chrome-plated "NASH" letters integrated into the grille trim. The interior also saw upgrades, including enhanced upholstery and trim.[17]

As the United States prepared for and entered World War II, automakers rapidly shifted their production focus to defense orders. Nash harbored hopes that the U.S. government would permit the continued, albeit highly restricted, production of the fuel-efficient Nash 600.[3] The rationale was to maintain a vital source of new, economical vehicles for civilian use during wartime.[18] Despite these efforts, approximately 5,400 units of the 1942 Nash 600 were produced before civilian car manufacturing was halted entirely in 1942, as the nation's industrial might was fully redirected towards the war effort.[3] Nash received almost $100 million in defense orders by September 1941.[18]

Post-war

Nash began post-World War II car production in the fall of 1945. It was a sellers' market in the late 1940s because many cars on the road were getting old or neglected due to scarcity of parts and lack of mechanics during wartime.[19] There was an urgency to build new cars and customers were accepting prewar designs. Nash was one of the "independent automakers" that stood out.[19] The Nash advantage was the cars' body structure with over 8,000 spot welds, gussets welded within the body structure, and non-removable fenders for additional rigidity.[1]

To differentiate the traditional body-on-frame construction, the showroom of Cooke Motor of Lexington, Kentucky, displayed a Nash 600 on its side so customers could see the innovative unibody construction.[20]

The models were mostly the same except for revised chrome trim and a projecting center section on the lower grille. Norman Bel Geddes designed this new grille and a new dashboard to differentiate the new cars from the pre-war versions.[21]

Unlike using the "Ambassador" nameplate on all three Nash series in 1941 and 1942, the 600 became the Nash 600, while the Ambassador nameplate was reserved for the senior model.

The 1946 model year "600" featured a rear seat that could be converted into a bed as an option.[22] It was possible to sleep with the legs tucked into the trunk area. The engine was updated and power increased to Template:Cvt at 3,800 rpm.[23]

A 1947 Nash 600, driven by Andy Henderson, won the challenging Script error: No such module "convert". Death Valley Economy Run, sponsored by Hancock Oil Company of California.[24][25] Henderson achieved Script error: No such module "convert". while maintaining an average speed of Script error: No such module "convert". driving steep mountains and through America's hottest desert.[26]

The only post-war year that Nash made a 600 in the business coupe body style was 1948.[27] This was the lowest-priced model with minimal features, lacking a back seat (to have room for samples) as well as no chrome trim, ornamentation, or comfort items such as a sun visor and door armrest.[27]

The 1948 Nash 600 (and Ambassador Custom) bore the work of Helene Rother, Nash's new interior stylist. They featured some of the most stylish interiors in the industry. Her contributions included upholstery and trim colors that harmonized with specific exterior colors.[28]

1949: Airflyte

The 1949 model year Nash 600 featured a new design based on the aerodynamic Airflyte series developed by Nils Erik Wahlberg, Nash's Vice President of Engineering.[29] The new cars stood out among the competition, Script error: No such module "convert". lower than the 1948s with a rounded body with unusual enclosed fenders. This was the streamlined appearance, commonly called ponton, that detractors dubbed them the "bathtub" Nashes. "The envelope shape was the most streamlined form on the road, a large step ahead of the vaguely similar Packard luxury models produced from 1948 through 1950.[30] The 600 became the economical series competing with Chevrolet, Ford, and Plymouth; while the Ambassador became the premium models and up against brands as Buick, Oldsmobile, Mercury, Chrysler, DeSoto, and Hudson.

The sedan was the only body style available in two- or four-door versions. Three trim series were offered: Super, Super Special, and Custom. The interiors were described as "cavernous". An unusual "Uniscope" instrument pod was mounted on the steering column. Optional was a new "Twin Bed" that transformed the car's interior into a double sleeping area, making it perfect for camping or impromptu overnight use. A long, upholstered horizontal surface was formed by dropping the two front passenger seatbacks down to meet with the bottom of the rear bench seat. Additional comfort was available by Nash dealer accessories, including form-fitting mattresses that filled gaps between the seats and snap-in screens for the door windows, to provide ventilation and keep out insects.

The 1949 Nash 600 series were built on a Script error: No such module "convert". wheelbase and carried over the previous Script error: No such module "convert". I6 engine, selling at lower prices than the Nash Ambassador series that now rode on a larger Script error: No such module "convert". wheelbase and boasted a standard Script error: No such module "convert". overhead-valve I6 engine with a durable seven-main bearing design.[31]
