Review of the model:

It will be a shame not to add the Tucker 48 car to ones collection, as this piece of history is vital to understand how auto motor companies can struggle to launch a newly foresighted car that took a look in to the future. In the 1:18 scale, the maker of the Yatming Group, Lucky Die-Cast has made the glorious Tucker 48 in many colors.

I choose the gold metallic as this suit the model well. When the parcel arrived and got unpacked, I was surprised over how big this car is! – 1948 was way before the longer, wider, lower was in  fashion! We have seen before, that the model cars from Lucky Die-Cast sometimes have trunks that can not be opened, but in this case the trunk and hood open fine. Furthermore this is a true sedan with four doors, that open fine. High-five to Lucky Die-Cast. The door arrangements is suicide doors, were the back doors open backwards. That gives a good look inside the interior. The inside of the model is okay in this price range, but the steering wheel is made of a too plastic/toy-like material, so I painted it in a more realistic color. The special gear shifter that protrudes out right of the steering pillar was missing, so I made a new one in styrene plastic.

The engine compartment lay in the back of the car and the Franklin flat straight six, is well made and I painted the Tucker name on the motor red. The grill has black paint in the holes, but the vertical trim lines in the mesh need some liquid chrome. On the lid we see a fine Tucker emblem in gold; a feature that indicates the maker care on details. Let’s go up front of the car and open the big trunk. This revealed surprisingly a nicely detailed interior, with spare wheel and 3 big suitcases. The models chrome parts is as always in good quality from Lucky Die-Cast, and this is also present in this model, just look at the fine hood ornament. Up here in the front, the grill is also well made and painted, but again the vertical trim parts need some extra chrome.

The wheels of the car are well molded and have fine hubcaps, with molded emblems in the center. To give the model a more realistic appearance, I painted the hubs red and the emblems black with gold ornament. Not a heavy workload to upgrade this model.
I must say this model is well made just out of the box. The window glass parts are clear and look realistic and the headlights lenses have mesh like moldings as the real car.
The paintwork on the model is flawless and always applied with high standard – sometimes surpasses the more expensive model out there. The most pronounced cons of the model are the “pupil effect” on the headlights and the gabs around the doors. Otherwise Lucky Die-Cast has made a fine model car of an historic vehicle.

What color shall your Tucker 48 have?
 

I will give this model 3 out of 6 stars  ******

History:

The Tucker 48 (named after its model year) is an automobile conceived by Preston Tucker and briefly produced in Chicago in 1948. Only 51 cars were made before the company ceased operations 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 the allegations were proven baseless and led to 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. 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".

Development
After World War II, the public was ready for totally new car designs, but the Big Three Detroit automakers had not developed any new models since 1941. This provided great opportunities for new, small automakers, which could develop new cars more rapidly 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 flat-6 rear engine, disc brakes, four-wheel independent suspension, fuel injection, the location of all instruments within reach of the steering wheel, seat belts, and a padded dashboard.
Even 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. 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. Lawson was named the Tucker Corporation's "chief stylist" in February 1946, immediately upon the company's formation.

In December 1946, Lawson resigned from the company after a disagreement with Preston Tucker, and shortly thereafter, now-famous 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. 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. 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. 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.

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. 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.

The Tucker automobile was originally named the "Boi," 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. 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.

Innovative design features
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 sub frame 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. 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. It had large pistons built of aluminum and magnesium castings with steel-plated cylinder linings. 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.

Troubled premiere
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. 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.

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. 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.

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.

Engine
Tucker had promised 150 hp (110 kW; 150 PS), but his innovative engine was not working out. The valve train proved problematic and the engine only produced approximately 88 hp (66 kW). The high oil pressure required a 24-volt electrical system, up to 60 volts to get it started, and a long cranking time at start-up. Additionally, the oil pressure required to maintain valve function was not achieved until the engine was turning at higher RPMs and Tucker's engineers struggled with keeping the valve train working at idle and lower speeds/RPMs. Having wasted nearly a year trying to make the 589 work, Tucker started looking for alternatives.

The company first tried the Lycoming aircraft engine, but it would not fit in the car's rear engine compartment.

An air-cooled flat-6 engine, the O-335 made by Air Cooled Motors (and originally intended for the Bell 47) fit and its 166 hp (124 kW; 168 PS) pleased Tucker. He purchased four samples for $5,000 each, and his engineers converted the 334 cubic inches (5,470 cc) engine to water cooling (a decision that has puzzled historians ever since). The Franklin engine was heavily modified by Tucker's engineers, including Eddie Offutt and Tucker's son Preston, Jr. at his Ypsilanti machine shop. Using an aircraft engine in an automotive application required significant modification; thus, very few parts of the original Franklin engine were retained in the final Tucker engine. This durable modification of the engine was tested at maximum power for 150 hours, the equivalent of 18,000 miles (29,000 km), at full throttle.

Tucker quickly bought Air Cooled Motors for $1.8 million to secure the engine source, and then canceled all of the company's aircraft contracts so its resources could be focused on making automotive engines. This was a significant decision, since at the time of Tucker's purchase, Franklin held over 65% of post-war U.S. aviation engine production contracts. The loss of income was substantial.

Transmission
With the horizontal, between the wheels 589 motor and its double torque converter(s) (and no reverse) drive system out; Tucker now needed a transmission to mate with the Franklin O-335. This motor was also horizontal, but its driveshaft pointed towards the front of the car. It was discovered, after a few sketches were made, that it was theoretically possible to adapt a previous transmission design intended for front-engine/front wheel drive use. This transmission served as a temporary "fix" for a very real problem for the success of the Tucker.

Pre-Selector Manual Transmission
Cord-Auburn Gear-Bendix Unit- It was discovered that the Cord 810/812's Auburn Gear, front-wheel-drive; 4-speed transmission, with the Bendix "Electric Hand" electro-vacuum shifting mechanism, fit the immediate design requirements needed to get the cars built, and on the road; until a future automatic (Tucker Built transmission) was worked out. This transmission was designed originally behind a standard V-8 engine, and pointed forward towards the front of the car, for the front wheels. That said, all wasn't adding water and mix to the end result. In this transmissions first iteration, was maligned by several factors; in it previous usage in the Cord Automobile. In fact, in 1936, when the Cord 810 made its debut at the New York Automobile show, because the transmissions were so problematic, were all mostly shown WITHOUT any transmission installed. And problems abound until the last Cord was produced in 1937. The Cord transmissions, even with refurbishing, could not handle the power and torque of the O-335 engine. Aside from a lack of proper lubrication (which also plagued it in a Cord as well), the main shaft thru the transmission was too long. This allowed the shaft to bend under load, causing gears to pop out of play, and gear-teeth were quite weak as well. So while a fix, it wasn't a GOOD fix. For the Tucker, this worked PERFECTLY for the engine configuration now in place, and it provided an adequate (if not fragile) transmission WITH a reverse gear. The company then sent several of its staff, including Preston Tucker Jr. on a buying spree acquiring these early CORD units. All told, (22) transmissions, were found by scouring junkyards, and used car lots. These transmissions were taken to Ypsilanti to the Ypsilanti Machine And Tool Company. After needed refurbishment, several were mated to the O-335. And it worked. 4 speeds forward and reverse. This was the harbinger in the earlier converter drive. It was decided, that this design, nearly 12 years old, HAD to be the "manual transmission" for the 1948 and beyond Tucker automobiles. Around 8 to 10 were found to be usable out of the 22, and were used until production versions were ready. Several of the original CORD based units are still today installed in the completed Tucker cars, as not enough of the Y-1's was ever completed.

Ypsilanti Y-1 Transmission
Ypsilanti Machine and Tool Company, which was tapped to recondition the Cord unit's, began immediately re-designing the transmission for mass production for Tucker. This new design, which had few similar parts to the Cord transmission, still used to same basic, indirect transmission design, but had all new gearing, shafts and, electro-vacuum controls. Tucker and his engineers modified it, installing stronger gears and lengthening the case. The modified Cord transmission was named the Tucker Y-1 (Ypsilanti-1) and was installed in a few Tuckers. Both again used a Bendix designed electric vacuum shift mechanism, with no mechanical linkage to the steering column shift lever. These EVS's had problems of their own, with electrical connections and vacuum leaks that hindered shifting, so a new fully mechanical shift design would have been needed, had the Tucker made it into 1949, and beyond.

Tucker-Matic Drive
To solve the transmission problems with a new final transmission design, Warren Rice, creator of the Buick Dynaflow transmission, was consulted. A unique continuously variable transmission called the "Tucker-Matic" was designed, which was strong enough to handle the Franklin O-335's power and torque. It was a simple but effective design, with double torque converters and only 27 basic moving parts, which was about 90 fewer than normally required for a contemporary automatic. The double torque converters allowed a continuously variable drive ratio with only one forward gear and one reverse gear which used the torque converters to vary the transmission ratio based on load and engine speed.

The only surviving car with a Tucker-Matic installed had a standard column shift lever, with a three position quadrant on the steering column. UP was reverse, the middle was neutral, and down was drive. Due to the Tucker-Matic's design, no low gear, or lower gears were necessary. Hence no need for multi gated selector like other automatics.

Three versions of the Tucker-Matic were made, the R-1, R-1-2, and R-3, (R for Warren Rice, its designer). The first version, the R-1, was not installed on any of the final cars. It required the engine to be off in order to select a gear. The R-1-2 was improved by adding a layshaft brake to allow gear selection while the engine was running. This version was installed on cars #1026 and 1042 only. The R-3 version had further improvements including a centrifugal clutch to help shifting between forward and reverse even further, but it was never installed in any of the final cars.

Because the two torque converters on the Tuckermatic made the engine-transmission unit longer, the fuel tank in the Tucker '48 had to be moved from behind the rear seat to in front of the dashboard for all Tuckers from car #1026 forward, even though only two of them actually had the Tuckermatic installed. This had the added advantage of improving weight distribution in the car.

Other Drives, contemplated for the Tucker 48
A Borg-Warner based, 3-speed automatic was supposedly tested and was installed on car #1048 at some point when the company was in business. Although no histories written ever mentioned such a drive. That said, Tucker ultimately wanted to design his own transmission for the final car, which came to fruition with the Tucker-Matic discussed below. In 1949, #1048 was sold at the receivership auction WITHOUT a transmission installed. Today, #1048 has the 4 speed pre-selector transmission that was used on ALL but 2 of the Original 50 pilot models. It is likely this transmission was installed privately after the auction transpired. Further likely that the unit was the Ypsilanti Built Y-1 transmission.

Suspension and body
Suspension designs, especially the front suspension, had to be changed throughout development. Rather than steel springs, Tucker used an elastomeric (rubber) 4-wheel independent suspension similar to what was used on the race cars he developed with Harry Miller at the Indianapolis 500. The rubber elastomers were developed with assistance from the Firestone Tire Company and used a special Vulcanization process to produce a specific spring rate.

Tucker's suspension designs were plagued with severe stiffness throughout development, which, while good for handling, caused front-wheel corner lift when cornering on uneven surfaces. The test bed and the prototype had a double-rubber disc type front and rear suspension, similar to Miller's race cars, which was too weak for the weight of a passenger car. On cars #1001 and 1002 the rear wheels could not be removed without removing the fender or suspension due to the stiffness of the suspension and the rear wheel arch fender design. From car #1003 on, the rear fender shape was changed so the tire could be removed easily. Aside from the fender changes, the rear suspension remained the same from car #1001 on.

Three versions of the front suspension were installed in the cars (aside from the rubber-disc style used on the prototype). Cars #1001–1002 used a rubber torsion tube design, which suffered from severe toe-in during heavy braking. Tucker then switched to a rubber sandwich type suspension (with a rubber block sandwiched between the upper and lower A-arms) on cars #1003–1025, however, this type was severely stiff. Starting on car #1026, Tucker finally settled on a suspension design with a modified version of the rubber torsion tube with the toe-in braking problem corrected.

Funding and publicity
Having raised $17,000,000 in a stock issue, one of the first speculative IPOs, Tucker needed more money to continue development of the car. He sold dealerships and distributorships throughout the country. Another money maker was the Tucker Accessories Program. In order to secure a spot on the Tucker waiting list, future buyers could purchase accessories, like seat covers, radio, and luggage, before their car was built. This brought in an additional $2,000,000.

With the final design in place, Preston Tucker took the pre-production cars on the road to show them in towns across the country. The cars were an instant success, with crowds gathering wherever they stopped. One report says Tucker was pulled over by a police officer intent on getting a better look at the car.

To prove the road-worthiness of his cars, Tucker and his engineers ran several cars at the Indianapolis Motor Speedway in several endurance tests. During this testing, car #1027 was rolled three times at 95 miles per hour (153 km/h), and the driver (chief mechanic Eddie Offutt) walked away with just bruises. During the crash, the windshield popped out as designed; verifying Tucker's safety features were effective. Afterwards, upon replacing a damaged tire, the car started up and was driven off the track.

SEC investigation and demise of Tucker Corporation
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.

Tucker '48 cars
The first Tucker produced was a prototype sedan, known as the "Tin Goose". Fifty-eight 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 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. 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.

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 while Tucker #1043 went for $2.915 million at auction in 2012.
