Fuel Alternatives

The latest wave in automotive engineering has brought about rapid innovations in the development of alternative fuel vehicles. Under pressure from consumers as well as government mandate, vehicle manufacturers large and small have launched a new generation of versatile, efficient models designed to run on renewable energy.

From Toyota and Honda to Ford and GM, most of the major auto lines now sport at least one version of flex-fuel in several major classes, and the trend will very likely sweep the industry. Unlike traditional gasoline engines, flexible fuel sedans, trucks and, most recently, sport utility vehicles, are able to fill up on either gasoline, a biofuel such as ethanol, or some mixture in between.

When combined with electric hybrid capabilities, these vehicles truly do go the extra mile, getting the fuel ratio of a light compact in the body of an SUV, which so recently was the mechanical symbol for wasteful eco-villainy among critics of oil-based energy policies.

Also referred to as FFV’s, flex-fuel vehicles retain the option of using regular gasoline when alternatives are not available, making them an attractive option for drivers who are wary of committing to a fuel for which the supply is irregular.

The majority of FFV’s are designed to make use of 70-85% ethanol blends known commercially as E85. This mixture has been used with great success for several years in Brazil, which prompted US automakers to hit the assembly lines with refits to their standard models in order to meet the domestic and foreign demand.

As with all budding technology, what holds back consumers from taking the flex-fuel plunge is the price tag. Despite tax rebates, buyers of FFV’s face stiff sticker shock in a time when the economy is lagging and going green is a luxury many strapped families feel they can do without,

Those who do let their conscience override their accountant may have to quest a bit to locate reliable sources of their alternative-often coping with irregular hours and shortages. The reality is that auto manufacturers have rapidly moved ahead of alternative fuel deployment, and until the supply surges to meet demand, it may still be a rough road for those who want to drive and promote clean air as well.
