Hy-Wire car is without hydraulic and mechanical linkage end engine. Instead of these it contains a fuel cell stack and a drive by wire system. It is fully automated future car. In future it will have a wide application. The problem with fuel consumption and pollution can be minimize to certain level.
Two basic elements largely dictate car design today: the?? internal combustion engine and mechanical and hydraulic linkages. If you have ever looked under the hood of a car, you?? know an internal combustion engine requires a lot of additional equipment to function correctly. No matter what else they do with a car, designers always have to make room for this equipment. The same goes for mechanical and hydraulic linkages. The basic idea of this system is that the driver maneuvers the various actuators in the car (the wheels , brakes, etc) more or less directly? by manipulating driving controls connected to those actuators by shafts, gears and hydraulics. In a rack and pinion steering system. For example, turning the steering wheel rotates a shaft connected to a pinion gear which moves a rack gear connected to the car?s front wheels. In addition to restricting how the car is built, the linkage concept also dictates how we drive. The steering wheel, pedal and gear shift system where all designed around the linkage idea.
In this seminar, we will look at one interesting vision of the future, General Motors remarkable concept car, the Hy-wire.
From last many years we have been facing the problem of pollution and environmental disaster. Much of the pollutants come under the category of vehicular pollution. Therefore we need to evolve a method to eliminate or at least decrease this problem.

The Hy-wire (Hydrogen drive-by-wire) is a concept car from General Motors originally introduced in January 2002. The car runs on hydrogen fuel cells and uses a drive-by-wire system, meaning that the car is controlled electronically. Due to hydrogen fuel cell drive system used by the Hy-wire, the conventional car layout has been revamped. Without the need for a conventional engine block and transmission system coupled to the steering column and pedals through mechanical linkage the car's power system and single electric motor are built into a flat skateboard configuration.
Since a fuel cell propulsion system is about twice as efficient as an internal combustion engine, a fuel cell vehicle could provide twice the fuel efficiency of a comparably sized conventional vehicle, and an optimized fuel cell vehicle like Hy-wire would be even more efficient. Since the reaction through which the power is generated is 2H2+O2=>2H2O the only bi-product formed is water, which is a non-pollutant. Since there is no burning or other oxidation process in the releasing of energy harmful components like nitrogen oxides, hydrocarbons, carbon oxides and other unburnt products are not produced. Hence these cars are highly eco-friendly.
Of course, this is a concept car. GM will use ideas from this in future autos, so it?s entirely possible that someday soon you'll drive a car with a front window that reaches from your toes to the roof, while you steer the car with a joystick set in the arm of a comfortable chair.
