US patent No. 8,011,274 disclosed above 1,000 multi-speeds gearbox apparatus designs. One provides: (1) to increase speeds number without additional gears number, (2) to cut up to 80%motor volume of excessive energy is added in motor, (3) to reduce                       motor cost and side, (4) to improve driving                                        safety by cutting  time of wheels changing speeds and stopping but they save time more on higher speed,     (5) to improve        city road traffics

Do you want to check how your car uses excessive motor power ? You can put maximum load on the car. The motor power is too much and transmission with "1", "2" etc is not need. if your car is moved from stop by using direct speed or "D" 
At 1886, the first world’s car with 779 power-to- weight ratio was pushed by the land friction force that defined motor size equal 0.75 HP from stop in Germany (Carl Benz’s patent #37435).

Archimedes (circa 287-212) said: “Give me a point of support and I will turn around the Earth by a lever” more than two thousand years ago.
At 1886, the first world’s car inventor Carl Benz proved that land friction force pushed his car with 779 power-to- weight ratio from stop that defined motor size equal 0.75 HP in Germany (patent #37435). It is fit today.
However, at 1908, car manufactures begun to use the motor INTERIOR ACCELERATION SYSTEM that requested increasing motor power up to 20 HP and more that eliminates to need using additional torque of any transmission that fulfills other function is the second brake.to acceleration system for additional energy consumption.
The use of shift gearbox as levers was too unconventional. There was “horse riding” time with much lower technical and sciences, education levels in condition of smaller human population, few machines in use and interest of “easy” money. 
Unfortunately, the tradition from over 100 years is to focus only to motor development with interior acceleration system took place at 21nd Century where, for example, over one billion of vehicles. The acceleration system requests up to 80% of additional steam, gas or electromagnet field to the motor standard consumed volume for too slowly acceleration of its shaft then machine wheels, propeller, spindle, etc. However motor shaft standard highest torque is reduced proportionally increased speed that requests increasing a motor size.
In results: 1) too huge motor directly joined to: a)wheels (locomotive), b) propeller (helicopter, ship, submarine, propeller airplane), c) spindle (CNC machine tool) ; 2) excessive motor torque eliminates to need additional transmission torque because shift gearbox was replaced by two clutches as are said automatic transmission of torque converter and continuous variable. They work also as brakes to motor acceleration system for its additional energy consumption at lightweight vehicle; 3) heavy-duty equipment use energy inefficient planetary and hydraulic transmissions, and 4) fossil fuel-burning plant continue to use steam as force for mechanical system of electricity generation.  
 The multi-speed gear-transmission is used only property by heavy-duty truck with up to 80,000 lbs. weight that is accelerated by gas too.. When a state-of-the-art gearbox apparatus installed and eliminated to use the acceleration system, the existing motor that produce 500 horsepower (HP) may be replaced with motors able to produce less than 100 HP with similar wheel torques capabilities to move vehicle at similar speeds with less time of acceleration by realizing wheels brake pedal. .
Modernization of fossil fuel burning power plant for reducing to use steam is installed state-of-the-art mechanical system between turbine and generator. Other way it is installed instead boiler and between electric motor with battery and turbine for eliminating to use steam as force. A battery is charged by wind or solar technology or both.  

At 1908, car manufactures begun to use the motor INTERIOR ACCELERATION SYSTEM that requested increasing motor power up to 20 HP and more that eliminates to need using additional torque of any transmission.
Today a state-of-the-art shift gearbox apparatus with nine shafts can  increase/reduce the torque shaft or power of motor  in up to 5x5x5x5x5x5x5x5=390,625 times
