Выпуск "Model F" - улучшенной версии "Model С" продолжался приблизительно до июня 1906. Хотя технически "Model F" относится к линии "1906" года, на самом деле эта модель была только переносом с 1905 и была заменена новой Моделью "N" с четырьмя цилиндрами. Новая "Model K" была первым (и последним до конца 1940-ых) "Фордом" с шестью цилиндрами. Достоинства шестицилиндрового мотора описываются в нижеприведённом тексте.

  The line of cars offered this year by the Ford Motor Co. embody the usual Ford ideas. It is Mr. Ford's desire to build a car that will not be out of date next year, nor the next year, nor the year after that. The idea of an automobile user thinking he has to change cars every year is as absurd as it would have been for the owner of a carriage to feel that a rig of that character was only good for one season.
  Four points must be conquered and satisfactorily settled—power, comfort, maintenance, cost.
  We invite your most careful inspection of the cars herein described, as well as a practical demonstration from our various agencies and branch houses.

MODEL K

  The constant study of the automobile situation since its inception, the experience secured from manufacturing and marketing thousands of successful motor cars, has enabled Mr. Ford to present a line of cars this year that will be accepted as a standard type of design for years to come. A car of this character could not be designed or built by anyone who had not had years of practical, successful experience.
  While the car abounds with radical features, not one is an experiment. Every one has been tried out at the expense of the Ford Motor Company. Every feature is along advanced ideas and is in the direction toward which all other manufacturers are tending.
  This car does not merely embody the carrying into execution of an idea of some one important phase of automobile construction, but is the careful evolution and development of every detail of the car, and it is these minute details that make the Ford Model "K."
  It is difficult to call your attention to the most important feature of this car, for of what value is simplicity of transmission if the ignition system is faulty? Of what benefit is the six-cylinder engine of wonderful power, when a weak rear axle drops your car in the road forty miles from home? What satisfaction can the automobilist get out of the fact that his oiling device is perfect after his steering equipment has gone back on him at .a critical moment? So, a car is only as strong as its weakest part, and, therefore, it must be a well-balanced car.

  The six vertical cylinders are cast separately with integral head, valve chamber and jacket. The interchangeable, mechanically operated valves are placed on one side, thus necessitating but one camshaft, one set of gears, simplifying the casting, and exposing less cylinder wall to the heat of the burning gas. The cylinders are made of a special east iron, carefully bored and reamed.
  The pistons, piston rings, wrist pins and crank-shafts are machined, then ground to size, which insures an absolutely perfect fit.
  The crank-shaft is a solid drop forging with a bearing between each cylinder. The bearings in the crank case are very large and long and that fact, together with the special fitting and adjustment received at factory before shipping, causes the wear to be so slight that the motor will run for years without attention to its bearings.
  It is not a difficult matter to make an engine so powerful that it will, with muffler cut out and full lead on the engine, snort up most any hill that is not perpendicular, even if you do not like the rattle and bang and repair bills resulting from the weight and vibration of an engine so heavy. Nor would it tax a designer, or even a bright machinist, to build a car that would not work up a big repair bill, but with so little power that it fails entirely when mud and sand and hills are encountered.

  So we see that it is not only necessary to have power but it is necessary to have the proper design and light construction and serviceability. The demand is for more power. It is a rational, sensible and reasonable demand.
  All prominent motor manufacturers acknowledge a limit in the size of a four-cylinder motor, beyond which trouble arises from added weight, decrease of motor speed, loss of motor flexibility, and increase of vibration due to the powerful impulses and heavy reciprocating parts. In the six vertical cylinders a happy solution of the question is found. The driving force is divided into six power strokes. The six cylinders develop light impulses in rapid sequence—in fact, before one impulse ceases the next begins. This applies the power so constantly and so uniformly to the driving shaft that no pulsations and no vibration is felt. This continuous, unbroken application of force, this constancy of torque, gives a smoothness of running, closely approaching the electric dynamo or steam turbine. The over-lapping impulses raise the pressure to a very high average, which greatly accentuates the gain in power.

Ignition

  The ignition is by high-tension magneto with an entirely independent and separate system in reserve fed by battery. This double system will be appreciated by experienced automobilists. The magneto works on an entirely new system and is far superior to any magneto yet constructed. One of the special features lies in the fact that the permanent magnets build up in use instead of weakening, as is the case with all other devices of this character. It produces a spark 3/8 inches long at fifty revolutions per minute, and three inches long at six hundred revolutions. Oil on the sparking plugs does not seem to affect the ignition owing to the high voltage of the secondary current. When cars are wired for both magnetos and storage batteries, the operator changes from magnetos to storage or from storage to magnetos by throwing a switch.

Transmission

  The Ford cars are designed with the idea of traveling over all ordinary roads, up and down the steepest grades, through long stretches of deep sand, etc., without touching the change speed lever. A light car and ample power permits traveling on direct drive practically all the time, so seldom is a lower gearing necessary. It is, therefore, obvious the simpler the device the more satisfactory it will be. The Ford system of planetary transmission is beyond question the most practical, most substantial and simplest arrangement of gears ever incorporated into the mechanism of an automobile. It absolutely does away with any possibility of confusion in operating the car. There are not two or more levers to operate, each depending upon the proper manipulation of the other. With the Ford system of control every motion is one which the operator would instinctively make. It requires little thought. If the wrong lever is applied the only possible result would be the stopping of the car. The Ford system of control is designed with especial effort to carry to the extreme that mostly desired, but often neglected, feature of a motor-car-Safety.
  Compare the necessary operations of the sliding gear system with the simple, yet powerful, planetary system as perfected in the Ford car. On direct drive no gears are used, no gears revolving idly in a bath of oil; no resistance or frictional loss in the Ford transmission.
  The Ford transmission, giving two forward speeds and one reverse, consists of a train of hardened steel gears, of extra wide face, always in mesh, and contained in a strong iron case and well protected. On the direct drive the gears are locked and the case revolves and acts as added flywheel weight. No more simple, efficient or positive arrangement could be devised. On the low gear a friction band holds the case stationary, thus putting into action a speed-reducing train of gears which are equally as efficient and powerful as the best system of sliding gears. The reverse is obtained by a friction band holding a disk connected to the reverse gear within the case. The adjustment of all speeds is very simple, consisting of adjusting nuts on each device, which are very accessible. The train of gears within the case are constantly submerged in a bath of oil, which is introduced through a small plughole in the outer circumference of the case.

  The direct drive is engaged through a multiple disk clutch, the most satisfactory mechanism yet devised. This clutch takes hold softly and does not jerk the car when applied. So gently does this clutch engage, Ford cars can be started from a standstill on the direct drive, without calling into action the gears of the low speed.
  To those unfamiliar with the construction of a multiple disk clutch we will explain it briefly. Consider several large bronze disks between each of which is placed a smaller steel disk. If the small disks are connected to a shaft and the larger disks to the transmission case, then when the disks are pressed tightly together it is clear that the large area of frictional surface would make an ideal coupling, easy to operate, quick to release and require little, if any, adjustment after long, continued service.

Controlling Levers

  A small horizontal throttle lever just beneath the steering wheel regulates the quantity of explosive mixture leaving the carburetor this variable quantity controlling the speed and power developed by the motor. This lever is on the left side of the steering column. On the right side is another small lever which regulates the time the charge on the cylinder is ignited. These levers are practically all that are used in the 1906 Ford cars, and control the car from the beginning of a trip to the end, regardless of hills, sand, mud or congested traffic.
  A vertical lever at the right of the seat controls, with the least possible inconvenience to the operator, the direct and low gear, the former being engaged at the extreme forward position of the lever, the latter at the extreme rear position, the mid position being neutral, the motor being disconnected. The reverse pedal is on the footboard. A second pedal on the footboard operates the powerful emergency brake on the driving shaft. A second vertical lever to the right of the seat operates the internally-expanding hub brakes on the rear wheels. There are, therefore, counting the reverse, three brakes available.

Axles

  The rear axle of the six-cylinder Ford touring car is, we firmly believe, the strongest, best supported axle ever constructed for automobile use. The outer sleeve is 3 inches in diameter. The spring perches are substantially pinned and then brazed. Hyatt Roller Bearings are used throughout this axle, and are extra long and large. This axle will last for years without trouble.
  The front axle is a one-piece steel drop forging of I-beam section, being extra heavy near the spring supports, the point of greatest strain.

Body

  Special attention has been given to the body of Model "K" to make it of most pleasing design. It is of the Victoria type with swelled panels and graceful in every line, yet eminently distinct in design. The seats are large, roomy and handsomely upholstered with buffed leather, rolling well back over the top edges and tufted over coil springs and curled hair.

Springs

  The springs of Model "K" have been given careful study. The rear springs are of the full-elliptic pattern while those in front are half-ecliptics, the front end of front spring being hinged directly to the extension arm of the frame and the rear end connected through swinging shackles to supports fastened to the steel side frame. These springs are extra long, and are made of a specially fine quality of steel which gives great strength and elasticity.

Wheels

  The wheels are of the wood artillery pattern, built of thoroughly seasoned second-growth hickory with spokes slightly dished, giving extra strength and flexibility and especially well designed to withstand extreme side-strains when turning corners at fast speed. All four wheels are 34 inches diameter, and are equipped with four-inch clincher tires.

Steering Gear

  Upon no part of the car does more responsibility rest than the steering mechanism. The new steering device on the Ford cars has received more favorable comment from mechanical engineers and automobile experts than any other device brought out this season. It is without back-lash or lost motion; cannot bind or stick. The reduction gears are of planetary principle and are housed in small brass drum just beneath the steering wheel. This construction allows of a solid construction at the lower end of the shaft, and makes it possible to steer the car with a minimum of effort.

Carburetor

  The carburetor is of the latest approved, automatically compensating type and supplies a perfect mixture to the motor regardless of engine speed or position of the throttle.

Frame

  The frame is of pressed steel, channel section, carefully designed to give ample strength to sustain the load without "sagging"; of sufficient rigidity or stiffness to withstand the strains over rough or uneven road surfaces.
