Engineers are working on hybrids (micro and full), electric vehicles, alternative fuel vehicles, and improvements to current powertrains all to help us reduce CO2 emissions and improve fuel economy. For example, stop/start systems are being introduced on vehicles so that the engine is shut down when the vehicle is just idling. The stop/start technology on its own is moving forward quickly. Hybrids use this feature to not only shut the gasoline engine down during idling, but also during cruising.
The driver has a large part to play in achieving good fuel economy. Automobile manufacturers have recognized this and are trying to help drivers to understand how they can improve. For example, some manual vehicles have shift indictor lights to help the driver know when to shift into a higher gear. Also, some vehicles monitor the driving patterns and provide ratings and feedback to the driver to help them improve.
New vehicle technology will certainly go a long way in helping us all be “greener,” but you do not have to wait for your next vehicle purchase to save on fuel. You can do it in your current vehicle by taking some simple actions.
The most important of these is to take steps to improve your driving style and to stay within the post speed limits. Emission levels are at their lowest for your vehicle when it is travelling between 40 and 60 mph. Use smooth transitions and anticipate upcoming traffic movements to avoid making harsh or aggressive stops and starts. Also, drive your car in as high a gear as possible to improve fuel economy.
Another tip is to keep your car well maintained. Your car needs to be serviced regularly to make sure it is running efficiently. It should be inspected at least once a year by a qualified technician. Also, you might want to consider monitoring your car’s fuel economy. A sudden change in your car’s fuel economy could mean that there is a mechanical problem the needs attention.
Also, purchase fuel with the gas octane rating that is recommended in your owner’s manual to keep your car running its best. Your car’s engine was designed around this octane level. If your car requires a higher octane level and you put a lower one in the tank, the engine will not run as efficiently has it could. Likewise, you do not need to buy premium gas if your manual does not recommend it. It will only cost you extra money, and you will be unlikely to see any extra fuel economy benefits.
Finally, make sure your tires are inflated to the recommended tire pressure. Tires that are under inflated have a higher rolling resistance and therefore require more energy, i.e. fuel, to keep them rolling forward. Also, remember that tire pressure changes with temperature, so you might have to check the pressure more often than you think.
The latest eco-friendly vehicle technology is very interesting and exciting. However, there are simple things that we all can do to make our current cars “greener” while we are window shopping for our new vehicles.
