This document discusses and compares specifications for the Honda CR-V, Honda Accord, and Chevy Equinox gas vehicles. It then discusses gas, hybrid, and hydrogen vehicle types and compares their advantages and disadvantages. Key points covered include the fuel economy and engine details for the vehicles listed, as well as the environmental impacts, infrastructure requirements, costs, and performance differences between gas, hybrid, and hydrogen technologies.

2. Honda CRV

redjar's photostream

3. Specifications for
Honda CR-V
• gets 22-27 miles per gallon.
• it’s a lower rpm vehicle so it burns less gas
• this would explain why the Honda CR-V
gets such a good fuel economy rating.
• 2WD models get better gas mileage
because the vehicle doesn’t need to put out
as much power the drive wheels.

4. Honda Accord
• Picture by:
Buster Benson's photostream

5. Specifications for
Honda Accord
• gets 20-25 miles per gallon.
• it has a lower center of gravity, which
increases aerodynamics.
• 4WD versions are not available.

6. Chevy Equinox

7. Specifications for
Chevy Equinox
• gets 19-20 miles per gallon.
• AWD models get lower fuel economy because all
wheels are turning all the time.
• 2.4L is the only motor available in this model
vehicle.
• Hybrid versions have no advantages over gas
models because of the size of the vehicle

8. Gas Vehicles
• 98% of americans use regular gasoline in
their vehicles.
• the first self-powered road vehicle was
powered by steam engines.

9. Hybrid Vehicles
• Hybrid vehicles require battery packs
• over time, batteries will lose power and will
need to be replaced.
• averages anywhere from $2,000- $2,500 to
replace the batteries.

10. Hydrogen Vehicles
• it’s an alternative fueled vehicle that uses hydrogen
for it’s onboard fuel for motive power.
• power plants convert the chemical energy of
hydrogen to mechanical energy by either burning
hydrogen in a internal combustion engine, or they
make it react with oxygen in a fuel cell to power
electric motors.

11. Disadvantages of Gas
Vehicles
• when ran they give off harmful emissions
into the ozone.
• there is no unlimited supply of oil, so we
will one day run out.
• fuel costs can differ from day-to-day.

12. Advantages of Gas
Vehicles
• there is less maintenance required.
• better towing and hauling capabilities.
• better vehicle life.

13. Hybrid vs. Gas
• you can travel further distances with hybrid
models vs. gas models.
• When the batteries are engaged in the hybrid,
there are less emissions given off.
• hybrids are more eco- friendly.

14. Disadvantages of
Hybrids.
• battery packs are costly.
• power is very limited.

15. Advantages of Hybrids.
• fuel milage is increased from gas models.
• when ran on batteries only, there are no
harmful fumes given off.

16. Hydrogen vs. Gas
• both hydrogen and gas vehicles are
internally combustion engines.
• when hydrogen is mixed with fuel it creates
NOx.
• hydrogen motors do not need a catalytic
converter to pass inspection.

17. Disadvantages of
Hydrogen
• decreases 5 horsepower from overall
horsepower from the engine.
• to convert gas stations to hydrogen filling
stations, the U.S. would have to create a
whole knew infrastructure to support the
switch from gasoline to hydrogen.

18. Advantages of
Hydrogen
• what is lost in horsepower is gained back in
miles per gallon.
• the only emissions that would be created
would be water vapor.

19. Hydrogen vs. Hybrid
• hydrogen doesn’t need to be plugged in
overnight for it to be charged.
• hybrids don’t require a large tank for liquid
fuel to be used.
• hydrogen vehicles in terms of range are like
gasoline care were about 40 years ago.
