Vehicle History

• They do not make them like they are.

first cars

• first cars were nothing more than a buggy and motor (General fix blacksmiths and carpenters. These cars were very expensive, that only the rich could afford it)
  
• Model T was the first automobile mass production on an assembly line in 1908 (Ford's vision was to produce an affordable car the average person can buy)
  
• Model T came in black only to costs. (Price dropped an assembly line was provided, but in 1908, the price of the Model T began at $ 825. By 1913 the car's price down to $ 550)

Cars in 1960

cars have the same basic way through the 60's

• in the body frame
  
• rear-wheel drive (the same concept, but the cars are very large, bulky and heavy)

In addition, people in the 60-ies wanted SPEED! They reached the Big Block Motors, which has created a lot of horsepower. (The Birth of Hotrods, Rat Fink, flames and pin striping).

cars in 1970

• Government place stringent fuel and emission control laws
  
• Customers demanded cars with increased fuel
  
• New laws and requirements of customers began to automotive engineering explosion of ideas and changes in the automotive industry

Changes in accordance with the requirements and laws

• Less powerful cars and smaller engines
  
• Aerodynamics (Increase Fuel Mileage)
  
• lighter cars using different materials and designs
  
• More work hardened areas resulting in the formation of the panel (body line)
  
• Security

The construction of interstate highway speed limits + high + more high performance cars = more accidents and

deaths from car accidents

Federal laws were passed to regulate safety. These laws are:

• Set the seat belts
  
• Safety glass windshield
  
• Headrests
  
• In 1979, the first driver side airbag was introduced
  
• Airbags are mandatory in cars manufactured after 1990
  
• Unibody torque boxes: Allow controlled twisting and crushing
  
• Crush zone: Built on collapsed during a crash (that acts as an absorber, absorbing the impact)

modern day Cars

• carbon fiber parts
  
• aluminum parts
  
• More plastic parts
  
• high strength steel
  
• Boron Steel
  
• Unibody Construction
  
• Space Frame construction
  
• computer
  
• Hybrid Cars

Now they even have a car that will tell you when you lost, where to turn, parallel park for you.

Conclusion

While today's cars that are cheap and insecure, they are actually designed to crush or collapse, while the transfer of energy around the taller passenger cabin to protect occupants from injury.

There is much more damage modern car during a crash than older vehicles, which gives the impression that "they do not seem to get used to." However, in reality, cars are a leading influence, rather than passengers.

The lesson is designed to give you a little history, but also emphasize that only a hammer, a dolly and some keys are not going to fix today's cars. We need highly trained technicians and automotive repair today's vehicles.
