Tucker 48

After World War II, the public was ready for new car designs, but the Big Three Detroit automakers had not developed any new models since 1941 due to the war and the fact their factories were used to produce war goods during the war. This provided opportunities for new, small automakers which could develop new cars faster than the huge legacy automakers. Studebaker was the first to introduce an all-new postwar model, but Tucker took a different track, designing a safety car with innovative features and modern styling. His specifications called for a water-cooled aluminum block[1] flat-6 rear engine, disc brakes, four-wheel independent suspension,[1] fuel injection, the location of all instruments within reach of the steering wheel, seat belts and a padded dashboard.

Before the war's end, Preston Tucker began working on plans for his new automobile. In the summer of 1944, he hired noted car designer George S. Lawson to style his new automobile.[6] Lawson worked on the project for over a year and a half before his design debuted publicly, beginning about February 1946 and found as late as a year later in March 1947.[7] Lawson was named the Tucker Corporation's "chief stylist" in February 1946, immediately upon the company's formation.[8]

In December 1946, Lawson resigned from the company after a disagreement with Preston Tucker, and shortly thereafter, stylist Alex Tremulis of local Chicago design firm Tammen & Denison was hired and furthered the development of the Lawson design. Tucker gave Tammen & Denison and Tremulis a three-month contract, which expired in March 1947 and was not renewed.[9] The culmination of Tremulis' efforts during this phase of design development was featured in a full-page advertisement run in numerous national newspapers in March 1947. Tremulis' design was based directly upon the work of George Lawson, but incorporated his own artistic flair.

Simultaneous with Tremulis' departure, Preston Tucker hired a team of five designers (Read Viemeister, Budd Steinhilber, Tucker Madawick, Hal Bergstrom and Phillip Egan) from the New York design firm J. Gordon Lippincott, who updated Tremulis' design just as Tremulis had done with Lawson's.[10]

After a month's absence, Tremulis was rehired and the two independent design groups developed full-size clay models side by side in direct competition.[9] Surviving photographs of the two models reveal that Tremulis' clay design remained unchanged from his March 1947 advertisement proposal and was not chosen for production. The passenger side of the Lippincott team's clay model (they submitted two designs), which incorporated the side profile developed by Tremulis prior to their arrival, was chosen virtually intact for the production automobile's styling.[10]

The Tucker 48's evolving appearance in the company's press releases and other promotional materials, combined with suggestive statements such as "15 years of testing produced the car of the year"—despite no running prototype existing at the time—were instrumental in the SEC filing mail and conspiracy fraud charges against Preston Tucker. The SEC, however, failed to prove its case, and Tucker was acquitted of all charges in January 1950.[11] However, the company never recovered.

Tremulis, like George Lawson, was eventually named the Tucker Corporation's "chief stylist," although the first reference to him holding this position does not appear until 1948, after the Tucker 48's exterior styling was completed.[12]

The Tucker automobile was originally named the "Torpedo," but was changed to "Tucker '48" around the time of Lawson's departure and Tremulis' arrival, reportedly because Tucker did not want to remind the public of the horrors of World War II. Despite the name change, the Tucker 48 is still often referred to as the Tucker Torpedo. Alex Tremulis has claimed responsibility for dubbing the first prototype automobile the "Tin Goose," which is presently used in a loving manner but at the time was considered derogatory.[13]

The Tucker was a pioneer in terms of engineering and safety features. A rear engine, rear wheel drive configuration had been employed in Tatras and Volkswagens, and headlamps that turned with the front wheels had been available since the 1920s, but they would have been firsts for a modern American production car. The most recognizable feature of the Tucker 48, was a third directional headlamp. Centrally located, it would activate at steering angles of greater than 10 degrees to light the car's path around corners. At the time, 17 states had laws against cars having more than two headlights.[15] Tucker fabricated a cover for the center light for use in these states.

The car had a rear engine and rear-wheel drive. A perimeter frame surrounded the vehicle for crash protection, as well as a roll bar integrated into the roof. The steering box was behind the front axle to protect the driver in a front-end accident. The instrument panel and all controls were within easy reach of the steering wheel, and the dashboard was padded for safety.[16] The windshield was made of shatterproof glass and designed to pop out in a collision to protect occupants. The car's parking brake had a separate key so it could be locked in place to prevent theft. The doors extended into the roof, to ease entry and exit.[15] Each Tucker that was built differed somewhat from the previous car, as each car built was basically a "prototype" where design features and engineering concepts were tried, improved, or discarded throughout the production cycle. The door releases on the interior of the Tucker came from the Lincoln Zephyr. The steering columns used in the Tucker were donated by Ford and are from the 1941 Lincoln. Preston Tucker held a patent for a collapsible steering column design. A glove box was added to the front door panels instead of the more conventional location in the dashboard to provide space for the "crash chamber" that the Tucker is now famous for. This is a padded area ahead of the passenger seat, free from obstructions, providing the front seat passengers an area to protect themselves in the event of an accident.[3] The engine and transmission were mounted on a separate subframe which was secured with only six bolts. The entire drive train could thus be lowered and removed from the car in minutes. Tucker envisioned loaner engines being quickly swapped in for service in just 30 minutes.[17]

Tucker envisioned several other innovations that were later abandoned. Magnesium wheels, disc brakes, fuel injection, self-sealing tubeless tires, and a direct-drive torque converter transmission were all evaluated or tested, but were dropped on the final prototype due to cost, engineering complexity, and lack of time to develop.[18]

Tucker initially tried to develop an innovative engine, with help from Ben Parsons, then owner and president of the Fuelcharger Corporation, and would later be Tucker's VP of engineering.[19] It was a 589 cubic inches (9.65 L) flat-6 cylinder with hemispherical combustion chambers, fuel injection, and overhead valves operated by oil pressure rather than a camshaft. An oil pressure distributor was mounted in line with the ignition distributor and delivered appropriately timed direct oil pressure to open each valve at proper intervals. The oil pressure fed to each valve was "timed" by intake and exhaust eccentrics and measured by spring-loaded plungers.[19] It had large pistons built of aluminum and magnesium castings with steel-plated cylinder linings.[19] This unique engine was designed to idle at 100 rpm and cruise at 250-1200 rpm through the use of direct-drive torque converters on each driving wheel instead of a transmission. It was designed to produce almost 200 hp (150 kW; 200 PS)1 and 450 lb⋅ft (610 N⋅m) of torque at only 1800 RPM. When cruising at 60 mph (97 km/h), it would only turn at approximately 1000 rpm.[19] These features would have been auto industry firsts in 1948, but as engine development proceeded, problems appeared. Six prototypes of the 589 engine were built, but it was installed only in the test chassis and the first prototype.[15]

The world premiere of the much-hyped Tucker 48 car was set for June 19, 1947. Over 3,000 people showed up at the factory in Chicago for lunch, a train tour of the plant, and the unveiling of the first prototype. The unveiling appeared doomed, however, as last-minute problems cropped up. The night before the premiere, two of the prototype's independent suspension arms snapped under the car's weight. (The prototype was extremely heavy; much heavier than the other 48s.) Minor engine problems were fixed, and the car was presentable by the time of the premiere. However, the experimental 589 engine was extremely loud. Tucker told the band to play as loud as possible to drown out the noise. Additionally the high-voltage starter required the use of outside power to get the engine started, so Tucker had the engineering team keep the engine running during the entire event, fearing that the public would see how much effort was required to get the engine started.[19] As the car was driven on to the platform, the liquid coolant boiled over and some steam escaped from the car, but no one seemed to notice.[10]

Drew Pearson, one of the top newspaper columnists of his time, reported publicly that the car was a fraud because it could not go backward and it went "goose-geese" going down the road.[20] Despite the fact that this problem was limited to the first prototype only, a symptom of the speed with which the first car was put together, the damage to the car's reputation was done, and a storm of negative media followed.[20]

Tucker suffered another setback when his bids to obtain two steel mills to provide raw materials for his cars were rejected by the War Assets Administration under a shroud of questionable politics.[21]

One of Tucker's most innovative business ideas caused trouble for the company. His Accessories Program raised funds by selling accessories before the car was even in production. After the war, demand for new cars was greater than dealers could supply, and most dealers had waiting lists for new cars. Preference was given to returning veterans, which meant that non-veterans were bumped down on the waiting lists indefinitely. Tucker's program allowed potential buyers that purchased Tucker accessories to obtain a guaranteed spot on the Tucker dealer waiting list for a Tucker 48 car.

This concept was investigated by the U.S. Securities and Exchange Commission and the United States Attorney, and led to an indictment of company executives. Although all charges were eventually dropped, the negative publicity destroyed the company and halted production of the car.

The first Tucker produced was a prototype sedan, known as the "Tin Goose". 58 frames and bodies were built at the factory. From these parts, 36 sedans were finished before the factory was closed. After the factory closed, but before liquidation of his assets, Tucker retained a core of employees who assembled an additional 14 sedans, for a total of 50. A 51st car was partially completed. A few of the remaining frames and bodies were built into complete cars specifically #1052 and #1057 (the 1949 prototype with design changes), but the fate of the others is unknown.

In the early 1950s, Ft. Lauderdale, Florida, fairgrounds owner Nick Jenin purchased over ten Tuckers, the original Tucker testbed chassis, numerous Tucker parts, photos and documents.[24] He developed a traveling display called "The Fabulous Tuckers". He hauled the cars and memorabilia around the country for nearly 10 years displaying them at fairgrounds and car shows. His display highlighted the questionable policies and SEC fraud investigation which brought Tucker down.[24]

When the cars appear at auction, which is rare, they command prices attained by only a few marquee cars. In August 2010, Tucker #1045 sold for $1.127 million,[25] while Tucker #1043 went for $2.915 million at an auction in 2012.[26]

In 1997, Rob Ida Automotive started work on a replica of the Tucker 48, which culminated in the release and marketing of the 2001 Ida Automotive New Tucker 48. This replica faithfully recreates the Tucker's external bodywork, but is built on a hotrod chassis with resin-infused plastic body panels. The paint and wheels reflect modern hotrod styling, and the interior is fully modernized. It is powered by a mid-mounted Cadillac Northstar V8. Its claimed performance is 0–60 in 7 seconds, with a top speed in excess of 120 mph (190 km/h). Ida has built three Tucker replicas.[52]

Several Tuckers were entered in the NASCAR Grand National series in the 1950s.[53]
