There is a clear and vocal demand in Spring and nationally for a reduction in air pollution and our dependence on fossil fuels. This is what is driving the TX market for alternative fuel vehicles. There are a number of these vehicles on Houston area roads today, and many more being developed. Yet each of these vehicles has its own advantages and disadvantages. Spring motorists should learn what these advantages and disadvantages are before running out and purchasing one of these alternative fuel vehicles at your nearest Houston dealership.
Houston car owners should carefully research the car care before buying an alternative vehicle, as it may or may not coincide with the standards for gasoline vehicles. You should look at costs and MPG as well: these vehicles may help save our environment here in Spring, but that might not represent a savings to your wallet. You’ll need to decide what you can afford, and what will work for your lifestyle. Also, your choice of vehicle may be affected by what fuels are available in your Houston area. Switching to an alternative fuel vehicle is not a bad decision, but it should be a carefully considered one.
Flex Fuel Vehicles
Flex fuel vehicles can run on gasoline or on a combination of 85% ethanol and 15% gasoline. Because of the 85% ethanol content, this fuel is commonly called E85 in TX.
Ethanol is made from corn. So flex fuel vehicles lessen our dependency on fossil fuels. But they also raise the price of corn, which is a basic foodstuff in some areas of the world. Whether replacing fossil fuels with corn is a good idea is hotly contested right now.
Flex fuel vehicles do have lower harmful exhaust emissions than gasoline-powered vehicles. And in Houston, E85 is usually lower in cost than regular gasoline. When gasoline prices fall in TX, however, they can drop below the price of E85. This is to Spring auto owners’ advantage, since the vehicle can run on either fuel, but it negates the benefits of lowered exhaust emissions and lower consumption of fossil fuels.
One piece of C&A Transmission & Auto Repair auto advice before we move on: do not put E85 into your family car unless it has an engine designed for flex fuels. Because of the high ethanol content in E85, engines need special seals and gaskets to function properly on this fuel. Running an ordinary engine with E85 can lead to gas leaks and fires.
Diesel engines are nothing new on TX expressways, and many get great MPG. Diesel fuel can now be made from vegetable oil and other renewable sources. A diesel fuel made from algae will soon be on the market in Houston.
Natural gas is less expensive than gasoline in Spring and burns more cleanly. Also, gasoline engines can be adapted to run on compressed natural gas, and many natural gas vehicles are already on Tomball roads. You can even install a special pump in your home gas line to use to fuel your vehicle. If you are interested in converting your gasoline engine to run on CNG in Spring, ask your C&A Transmission & Auto Repair tech about it.
On the other hand, an engine running on natural gas is not as powerful as one running on gasoline, and it will get lower MPG. Also, the tank you need to store natural gas is large—it takes up nearly the entire trunk of your car. Further, refueling stations are still few and far between in some TX areas, or even unavailable, in many parts of the country.
Another alternative fuel that has enjoyed a lot of hype in Houston is the hydrogen cell. The natural appeal is that the only exhaust is water vapor. In other words, hydrogen represents a truly clean-burning fuel. But hydrogen vehicles won’t come into widespread use until refueling stations become widely available here in Spring and around the country.
Electric vehicles were all the rage in TX some years ago. But their limitations were quickly realized by Spring motorists. These vehicles won’t come into their own until we find ways to improve their batteries. Currently, the cars have a short range before their power runs out, and can only be realistically used close to home. However, they are easy to recharge, since they can be plugged in at home, and there are many researchers working on improving the battery technology in these vehicles. They may yet be the vehicles of the future.
Hybrids have been one of the most successful alternative fuel vehicles here in Spring and throughout the county. A hybrid gets its name because it has both a gas or diesel engine and an electric motor.
There are two types of hybrids. The full-hybrid relies on the electric motor for power, but the gas (or diesel) engine generates power for the battery. Thus, while still consuming fossil fuels, it uses less of them than a standard automobile, and also reduces harmful pollutants. Also, it overcomes the range problem of the strictly electric vehicle.
In a mild hybrid, the electric motor assists the gas or diesel engine in powering the car. Thus, it uses more gasoline or diesel than full hybrids and has higher emissions. But mild hybrids are available in larger body models like full-size pickups and SUV’s.
A Note of Caution about Hybrid and Electric Vehicles
One last note before we leave the subject of alternative fuel vehicles. The battery in an electric or hybrid vehicle is not as tame as the one in a standard vehicle. They carry enough voltage to kill you. These are not do-it-yourself vehicles when it comes to preventive maintenance or car care. Only a trained technician should work under their hoods.
