Pakistan First self made Hybrid Car
A hybrid vehicle is a vehicle that uses two or more distinct power sources to move the vehicle.

The term most commonly refers to hybrid electric vehicles (HEVs), which combine an internal
combustion engine and one or more electric motors.
The students of nust university made a beautiful Hybrid car
This is a asian's first student self made hybrid car ,
Student of engneering decide to make the hybrid car as their project .
This car is assembled under limited resources , inspite of that it is very nice one.
speed of the car is 35 kilomerter per hour
and it capability is 110 kilometer per liter
in this car mechanical and electrical energies are combined and due to this reason it can travell more in small quantity of petrol with respect to other vehicale.
160 kg by weight and 1.25 meter long this car is very amazing to its construction .
in Malysia car got fame but at the returning to Pakistan , it is still on Karachi port .
May be few people are familiar with hybrid technology in Pakistan .
Hybrid car is economically very attractive . In this technology fuel consumption can be reduced .
Feature of Hybrid Car
Fuel consumption and emissions reductions The hybrid vehicle typically achieves greater fuel economy and
lower emissions than conventional internal combustion engine vehicles (ICEVs), resulting in fewer emissions
being generated. These savings are primarily achieved by three elements of a typical hybrid design:
* relying on both the engine and the electric motors for peak power needs, resulting in a smaller engine sized more
for average usage rather than peak power usage. A smaller engine can have less internal losses and lower weight.
*having significant battery storage capacity to store and reuse recaptured energy, especially in stop-and-go traffic,
which is represented by the city driving cycle.

*recapturing significant amounts of energy during braking that are normally wasted as heat. This regenerative braking
reduces vehicle speed by converting some of its kinetic energy into electricity, depending upon the power rating of the motor/generator;

Other techniques that are not necessarily 'hybrid' features, but that are frequently found on hybrid vehicles include:
*shutting down the engine during traffic stops or while coasting or during other idle periods;
*improving aerodynamics; (part of the reason that SUVs get such bad fuel economy is the drag on the car.
A box shaped car or truck has to exert more force to move through the air causing more stress on the engine
making it work harder). Improving the shape and aerodynamics of a car is a good way to help better the fuel
economy and also improve handling at the same time.

economy and also improve handling at the same time.
*using low rolling resistance tires (tires were often made to give a quiet, smooth ride, high grip, etc.,
but efficiency was a lower priority). Tires cause mechanical drag, once again making the engine work harder,
consuming more fuel. Hybrid cars may use special tires that are more inflated than regular tires and stiffer
or by choice of carcass structure and rubber compound have lower rolling resistance while retaining acceptable
grip, and so improving fuel economy whatever the power source.

*powering the a/c, power steering, and other auxiliary pumps electrically as and when needed ;
this reduces mechanical losses when compared with driving them continuously with traditional engine belts.

These features make a hybrid vehicle particularly efficient for city traffic where there are frequent stops, coasting and idling periods.
In addition noise emissions are reduced, particularly at idling and low operating speeds, in comparison to conventional engine vehicles.
For continuous high speed highway use these features are much less useful in reducing emissions.
