    The first decade of 21century introduced the world with a lots new technologies
     in the world of Automobile Industry. These sudden changes brought about the
     dawn of a new era in the world of vehicles. Today’s cars are much more
     complicated than they were just one generation ago. The very sudden changes in
     field of technology has taken the transportation to new heights. The automobile
     is a technology that has changed society dramatically over the last century. But
     not only society changed, the technology of the motorcar itself has changed
     significantly. The larger research project to which this paper belongs deals with
     changes in automotive technology from 2001 to 2011. The technology today
     has made journey more Safer, Simpler, Comfortable, Less Time Consuming and
     eco-Friendly. The technological development we are talking about is
     Performance, Durability, Cost, Assembly Feasibility, Safe Engineering & Fuel
     Economy. These were the foremost demands of people and there wishes have
     come true with the development in technology.
 The history of automobiles comes into frame from 1885 when “Petroleum
 Reitwagen/ Motorwagen” the first four-stroke cycle gasoline engine was
 invented by KARL BENZ in Germany. This invention brought about a new
 change in the world of transportation.
 In early days the engines were just simple 4-stroke engines, Hydraulic Brakes
 were used, engines were less efficient, fuel economy was not good, the models
 were bulky, there was a compromise with safety and comfort as well. The
 previous century technology did not had as equipments as of today.
 In early days of automobile industry it took a long time in the process of
 building and manufacturing due to lack of machines.
 So in order to remove all this these drawbacks there came a revolution in the
 field of developing technologies as it is purely said that “Necessity is the
 Mother of Inventions” and this is well proved in the field of automation.
   The Engine Control Unit normally contains a 32-bit, 40 MHz processor; this is very
    small compared to a normal PC with a 500 – 1,000 MHz processor.
   ECU- controls engine functions
   Airbag Module- controls airbag deployment
   Body Controller- controls interior lights, door locks, windows, seats, etc
   Driver's Door Module- communicates commands from switches on drivers door to the
    body controller
   Cruise Control Module- Regulates speed while in cruise control
   Climate Control Module- Monitors interior temperature and controls the heating and
    cooling systems
   Transmission Controller- controls automatic transmission
   ABS Module- controls anti-lock brakes and may handle the traction-control and stability-
    control systems
   Power Distribution Box Module- controls relays in the power distribution box
   Instrument Panel- Controls gauges, and indicator lights using data from the
    communications bus
   V-10 & V-12 Engines.
Electric Concept
   An electric car is an automobile which is propelled by electric motor(s), using
    electrical energy stored in batteries or another energy storage device.
   Electric cars have several potential benefits as compared to conventional internal
    combustion automobiles that include a significant reduction of urban air pollution.
