1. Hybrid Cars
Presentation of Netta Laczkovics

2. Personal Introduction
 Netta Laczkovics
 BME Mechanical Engineering
 BSc in Industrial Design Engineering
 Second year

3. Introduction
 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 combines an internal combustion engine and one or
more electric motors.

4. The spread of Hybrids
 Problems -Harmful effects on the Earth’s environment
-Dependence of fossil fuels
-High fuel prices
Electric cars ar not the answer: while electric vehicles are qualified as Zero
Emission, they are not quite practical. Only ideal for short trips around town,
but not so good for cross-country trips…
…This is where hybrid technology becomes key!

5. Types of hybrid cars
 Electric hybrids: use the electric motor as their alternative energy source
 Plug in
 Rechargeable energy storage system (RESS)
 Hydrogen hybrids: extract the element from water and add the hydrogen to
the fuel-air mixture of the vehicle
Power sources for hybrid vehicles:
 Gasoline or Diesel fuel
 Hydrogen
 Compressed air
 Liquid nitrogen

6. Environmentally friendly
 Hybrid cars can play a significant role in solving major problems faced by the
world such as,
1. Climate change
2. Air pollution
3. Oil dependence

7. How it works

8. ADVANTAGES DISADVANTAGES
 Lower emmision
 Better mileage
 Very quiet
 Consume less fuel
 Environmentally friendly
 Warranted
 Money saved
 Expensive
 Producing them still harms the
environment /carbon footprint/
 Shorter range
 More weight due to heavy battery
packs

9. Timeline
 1839, First electric vehicle
 1890-1910 Significant improvement in battery technology (lead acid, nickel
iron)
 1997, the first modern hybrid electric car, the Toyota Prius, was sold in Japan
 1999 Honda Insinght released in US
 2000, Toyota Prius available in US
 2002, Honda Civic introduced
 2004, Toyota Prius II introduced, Ford Escape Hybrid introduced

10. Today….future?
 The future for Hybrids looks bright with rapid developments in hybrid
technology to improve engine efficiency
 Due to Regenerative Braking Technology, the batteries need not to be
charged anymore by an external source.
 Hybrids help reduce the dependency on fossil fuels
Do You think hybrid cars are the way of the future?

11. Why hybrid cars
 Concern that the battery-operating engine would not last 8 years and
batteries cost $2000-$3000 to replace
Honda & Toyota both offer 10 years warrenties on the electric motor
 Tax incentives for buying hybrid vehicles (in the US)
If you were given the choice between a hybrid car and a conventional car and they were
the same price which one whould you choose?

12. Conclusion
 Still the hybrids might be in the cradle locks but as the technology increases
gradually „The Hybrids” would be replacing „The Conventionals” in order to
be fuel efficient and act as a Helping Hand to the Environment.
 Although costly in the market but having a long term vision for the hybrids is
profound to hit the causes of helping Fuel Draught that might occur in the
near future.
