Monday 7th July 1947

75 years ago

The Tucker 48 was shown in an exclusive preview at the Hotel Statler in Washington DC. Only 51 cars were made before the company folded on March 3, 1949, due to negative publicity initiated by the news media, a Securities and Exchange Commission investigation and a heavily publicized stock fraud trial (in which allegations were proven baseless in court with a full acquittal). Speculation exists that the Big Three automakers and Michigan senator Homer S. Ferguson also had a role in the Tucker Corporation's demise.[citation needed] The 1988 movie Tucker: The Man and His Dream is based on the saga surrounding the car's production. The film's director, Francis Ford Coppola, is a Tucker owner and displays his vehicle on the grounds of his winery. The 48's original proposed price was said to be $1,000, but the actual selling price was closer to $4,000. A 1948 Tucker sedan was featured in the July 26, 2011, installment of NBC's It's Worth What? television show. The car's estimated value at that time was US$1,200,000. The car is commonly referred to as the "Tucker Torpedo". This name was never used in conjunction with the actual production car, and its name was officially "Tucker 48". Some components and features of the car were innovative and ahead of their time. The most recognizable feature of the Tucker '48, a directional third headlight (known as the "Cyclops Eye"), 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. Tucker fabricated a cover for the cyclops 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. 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. Each Tucker 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. 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. 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. 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.[18] 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.[18] Built of aluminum and magnesium castings with steel-plated cylinder linings, the huge pistons required up to 60 volts to turn over the starter, nearly triple the power of a normal starter. 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. 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.
