The Ford Model T (colloquially known as the "tin Lizzie", "leaping Lena", "jitney" or "flivver") is an automobile produced by Ford Motor Company from October 1, 1908, to May 26, 1927. It is generally regarded as the first affordable automobile, which made car travel available to middle-class Americans. The relatively low price was partly the result of Ford's efficient fabrication, including assembly line production instead of individual hand crafting.
The Ford Model T was named the most influential car of the 20th century in the 1999 Car of the Century competition, ahead of the BMC Mini, Citroën DS, and Volkswagen Type 1. Ford's Model T was successful not only because it provided inexpensive transportation on a massive scale, but also because the car signified innovation for the rising middle class and became a powerful symbol of the United States' age of modernization. With 16.5 million sold, it stood eighth on the top-ten list of most sold cars of all time, as of 2012.

Introduction
Although automobiles had been produced from the 1880s, until the Model T was introduced in 1908, they were mostly scarce, expensive, and often unreliable. Positioned as reliable, easily maintained, mass-market transportation, the Model T was a great success. In a matter of days after the release, 15,000 orders had been placed. The first production Model T was built on August 12, 1908 and left the factory on September 27, 1908, at the Ford Piquette Avenue Plant in Detroit, Michigan. On May 26, 1927, Henry Ford watched the 15 millionth Model T Ford roll off the assembly line at his factory in Highland Park, Michigan.
Henry Ford conceived a series of cars between the founding of the company in 1903 and the introduction of the Model T. Ford named his first car the Model A and proceeded through the alphabet up through the Model T, twenty models in all. Not all the models went into production. The production model immediately before the Model T was the Model S, an upgraded version of the company's largest success to that point, the Model N. The follow-up to the Model T was the Ford Model A, rather than the "Model U". The company publicity said this was because the new car was such a departure from the old that Ford wanted to start all over again with the letter A.
The Model T was Ford's first automobile mass-produced on moving assembly lines with completely interchangeable parts, marketed to the middle class. Henry Ford said of the vehicle:
I will build a motor car for the great multitude. It will be large enough for the family, but small enough for the individual to run and care for. It will be constructed of the best materials, by the best men to be hired, after the simplest designs that modern engineering can devise. But it will be so low in price that no man making a good salary will be unable to own one – and enjoy with his family the blessing of hours of pleasure in God's great open spaces.
Although credit for the development of the assembly line belongs to Ransom E. Olds, with the first mass-produced automobile, the Oldsmobile Curved Dash, having begun in 1901, the tremendous advances in the efficiency of the system over the life of the Model T can be credited almost entirely to Ford and his engineers.
Characteristics
The Model T was designed by Childe Harold Wills, and Hungarian immigrants Joseph A. Galamb and Eugene Farkas. Henry Love, C. J. Smith, Gus Degner and Peter E. Martin were also part of the team. Production of the Model T began in the third quarter of 1908. Collectors today sometimes classify Model Ts by build years and refer to these as "model years", thus labeling the first Model Ts as 1909 models. This is a retroactive classification scheme; the concept of model years as understood today did not exist at the time. The nominal model designation was "Model T", although design revisions did occur during the car's two decades of production.
Engine
The Model T has a front-mounted 177-cubic-inch (2.9 L) inline four-cylinder engine, producing 20 hp (15 kW), for a top speed of 40–45 mph (64–72 km/h). According to Ford Motor Company, the Model T had fuel economy on the order of 13–21 mpg‑US (16–25 mpg‑imp; 18–11 L/100 km). The engine was capable of running on gasoline, kerosene, or ethanol, although the decreasing cost of gasoline and the later introduction of Prohibition made ethanol an impractical fuel for most users. The engines of the first 2,447 units were cooled with water pumps; the engines of unit 2,448 and onward, with a few exceptions prior to around unit 2,500, were cooled by thermosiphon action.
The ignition system used in the Model T was an unusual one, with a low-voltage magneto incorporated in the flywheel, supplying alternating current to trembler coils to drive the spark plugs. This was closer to that used for stationary gas engines than the expensive high-voltage ignition magnetos that were used on some other cars. This ignition also made the Model T more flexible as to the quality or type of fuel it used. The system did not need a starting battery, since proper hand-cranking would generate enough current for starting. Electric lighting powered by the magneto was adopted in 1915, replacing acetylene and oil lamps, but electric starting was not offered until 1919.
The Model T engine was produced for replacement needs, as well as stationary and marine applications until 1941, well after production of the Model T had ended.
The Fordson Model F tractor engine, that was designed about a decade later, was very similar to, but larger than, the Model T engine.

Transmission and drive train
The Model T is a rear-wheel drive vehicle. Its transmission is a planetary gear type billed as "three speed". In today's terms it is considered a two-speed, because one of the three speeds is reverse.
The Model T's transmission is controlled with three floor-mounted pedals and a lever mounted to the road side of the driver's seat. The throttle is controlled with a lever on the steering wheel. The left-hand pedal is used to engage the transmission. With the floor lever in either the mid position or fully forward and the pedal pressed and held forward, the car enters low gear. When held in an intermediate position, the car is in neutral. If the left pedal is released, the Model T enters high gear, but only when the lever is fully forward – in any other position, the pedal only moves up as far as the central neutral position. This allows the car to be held in neutral while the driver cranks the engine by hand. The car can thus cruise without the driver having to press any of the pedals.
In the first 800 units, reverse is engaged with a lever; all units after that use the central pedal, which is used to engage reverse gear when the car is in neutral. The right-hand pedal operates the transmission brake – there are no brakes on the wheels. The floor lever also controls the parking brake, which is activated by pulling the lever all the way back. This doubles as an emergency brake.
The three pedal controls of the Model T
Although it was uncommon, the drive bands could fall out of adjustment, allowing the car to creep, particularly when cold, adding another hazard to attempting to start the car: a person cranking the engine could be forced backward while still holding the crank as the car crept forward, although it was nominally in neutral. As the car utilizes a wet clutch, this condition could also occur in cold weather, when the thickened oil prevents the clutch discs from slipping freely. Power reaches the differential through a single universal joint attached to a torque tube which drives the rear axle; some models (typically trucks, but available for cars, as well) could be equipped with an optional two-speed Ruckstell rear axle shifted by a floor-mounted lever which provides an underdrive gear for easier hill climbing. The heavy-duty Model TT truck chassis came with a special worm gear rear differential with lower gearing than the normal car and truck, giving more pulling power but a lower top speed (the frame is also stronger; the cab and engine are the same). A Model TT is easily identifiable by the cylindrical housing for the worm-drive over the axle differential. All gears are vanadium steel running in an oil bath.

Body
Although Ford classified the Model T with a single letter designation throughout its entire life and made no distinction by model years, enough significant changes to the body were made over the production life that the car may be classified into several style generations. Among the most immediately visible and identifiable changes were in the hood and cowl areas, although many other modifications were made to the vehicle.
1909–1914 – Characterized by a nearly straight, five-sided hood, with a flat top containing a center hinge and two side sloping sections containing the folding hinges. The firewall is flat from the windshield down with no distinct cowl.
1915–1916 – The hood design is nearly the same five-sided design with the only obvious change being the addition of louvers to the vertical sides. A significant change to the cowl area occurred with the windshield relocated significantly behind the firewall and joined with a compound-contoured cowl panel. In these years electric headlights replaced carbide headlights.
1917–1923 – The hood design was changed to a tapered design with a curved top. The folding hinges were now located at the joint between the flat sides and the curved top. This is sometime referred to as the "low hood" to distinguish it from the later hoods. The back edge of the hood now met the front edge of the cowl panel so that no part of the flat firewall was visible outside of the hood. This design was used the longest and during the highest production years, accounting for about half of the total number of Model Ts built.
1923–1925 – This change was made during the 1923 calendar year, so models built earlier in the year have the older design, while later vehicles have the newer design. The taper of the hood was increased and the rear section at the firewall is about an inch taller and several inches wider than the previous design. While this is a relatively minor change, the parts between the third and fourth generations are not interchangeable.
1926–1927 – This design change made the greatest difference in the appearance of the car. The hood was again enlarged, with the cowl panel no longer a compound curve and blended much more with the line of the hood. The distance between the firewall and the windshield was also increased significantly. This style is sometimes referred to as the "high hood".
The styling on the last "generation" was a preview for the following Model A, but the two models are visually quite different, as the body on the A is much wider and has curved doors as opposed to the flat doors on the T.
