What You'll Learn
Ethanol is cheaper per gallon than regular gasoline
The price of ethanol is not always better than the price of gasoline except by volume. Biofuel groups have disputed that ethanol will lead to higher gas prices, and it is true that ethanol is often cheaper than gasoline—in about a third of the months since January 1982 when the Department of Agriculture first began collecting data, ethanol has been cheaper. However, ethanol advocates who describe it as cheaper than gasoline are usually overlooking the fact that ethanol is cheaper by volume but not by energy content.
Ethanol is made from ingredients such as cane sugar and corn, and corn is the primary source of ethanol. This makes ethanol a good alternative to purchasing foreign oil, and it is often cheaper than gasoline. However, ethanol requires a significant energy input, such as fertilizer from natural gas and diesel fuel for farm equipment. Therefore, there is a correlation between oil and gas prices and the price of ethanol.
E85 is a blend of 85% ethanol and 15% gasoline that can be used in vehicles designed to run on it, as well as regular gasoline. E85 is cheaper than gas and its prices have been falling, but it might not save you money to fill up your car with it because of the lower mileage per gallon.

Flex-fuel vehicles have similar mileage to regular fuel-powered vehicles
The flex-fuel system, also known as flexible fuel, is an alternative fuel made of a combination of gasoline and methanol or ethanol. Flex-fuel vehicles are those that have internal combustion engines designed to run on more than one type of fuel. While some experts assert that flex-fuel vehicles have similar mileage as regular fuel-powered vehicles, others claim they have lower gas mileage.
One of the main concerns about driving a flex-fuel car is its gas mileage. While some experts assert that flex-fuel vehicles have similar mileage as regular fuel-powered vehicles, others claim that due to ethanol's lower energy content, flex-fuel vehicles will have lower gas mileage. Ethanol does raise a vehicle's octane level, but it contains less energy, meaning it will take 1.5 times more to provide the same energy levels. As a result, you will get fewer miles per gallon using ethanol. However, ethanol costs less than regular gasoline, so the savings should more than offset the mileage loss.
The benefit of a modern flex-fuel vehicle is that you can use any combination of gasoline and ethanol, whether it's 100 per cent unleaded gas or 85 per cent ethanol. Modern flex-fuel cars can contain 10 to 85 per cent ethanol. Thanks to the technology it's equipped with, your vehicle will determine the most efficient proportions. Many flex-fuel vehicles run on ethanol, which is sustainably produced from ingredients such as cane sugar and corn. This makes ethanol a good alternative to purchasing foreign oil.
While flex-fuel vehicles have some differences, such as larger fuel pumps and injectors due to the lower energy density qualities of high ethanol mixtures, they are virtually identical to gasoline-only models. There are no special repairs or maintenance concerns when you own a flex-fuel vehicle. For the most part, the flex-fuel system parts even cost the same to repair or replace.

Flex-fuel vehicles are virtually identical to gasoline-only models
Flex-fuel vehicles are designed to run on gasoline or a blend of gasoline and ethanol. They are equipped with electronic sensors that gauge the blend of fuel and make the necessary adjustments for optimal fuel injection and combustion timing. This technology was first introduced in the early 1990s and has been used in mass-produced vehicles since then.
Flex-fuel vehicles have some differences in the areas of the engine and fuel system that come into contact with the fuel. These include larger fuel pumps and injectors, as well as corrosion-resistant fuel pumps, fuel lines, fuel injectors, and fuel tanks. Additionally, cylinders, pistons, valves, and other internal engine components are coated with a special material to resist the corrosive properties of ethanol. Despite these modifications, flex-fuel vehicles are considered to be virtually identical to gasoline-only models.
The main advantage of flex-fuel vehicles is their ability to use different types of fuel, including standard pump gasoline and ethanol blends such as E85 (a blend of 85% ethanol and 15% gasoline). This flexibility provides drivers with more options when it comes to fuelling their vehicles and can be particularly beneficial in areas where E85 is more readily available or where ethanol is produced locally.
While flex-fuel vehicles offer greater fuel choice, they may experience reduced fuel efficiency when using ethanol blends due to the lower energy content of ethanol compared to gasoline. This means that vehicles using E85 may travel fewer miles per gallon, resulting in higher costs to cover the same distance. However, the lower price of E85 compared to regular gasoline can offset the reduction in miles per gallon, making it a cost-effective option in certain situations.
In terms of performance, flex-fuel vehicles do not experience any loss in performance when operating on E85. In some cases, they may even generate more torque and horsepower when using ethanol blends. Additionally, flex-fuel vehicles do not have any special repair or maintenance requirements, and the parts for the flex-fuel system typically cost the same to repair or replace as those for gasoline-only vehicles.

Flex-fuel vehicles can burn any proportion of fuel mixture
The cost of a flex-fuel car is relative to the make and model of the vehicle. However, flex-fuel vehicles are not necessarily more expensive than their gasoline-only counterparts. In fact, flex-fuel vehicles are virtually identical to gasoline-only models, except for a few modifications to the engine and fuel system.
The ability of flex-fuel vehicles to burn any proportion of fuel mixture provides several benefits. Firstly, it allows for greater flexibility in fuel choice, as users can choose the blend that best suits their needs and budget. Secondly, it helps to improve the vehicle's performance, as the sensors and microprocessors ensure that the engine is always operating at optimal levels. Additionally, ethanol burns cleaner than gasoline, emitting lower levels of greenhouse gases and carcinogens, making flex-fuel vehicles a more environmentally friendly option.
However, there are also some drawbacks to consider. One of the main concerns with flex-fuel vehicles is their gas mileage. While some experts claim that flex-fuel vehicles have similar mileage to regular fuel-powered vehicles, others argue that they have lower gas mileage due to ethanol's lower energy content. As a result, flex-fuel vehicles may get fewer miles per gallon, which can offset the savings from ethanol's lower cost.
In conclusion, flex-fuel vehicles offer the advantage of being able to burn any proportion of fuel mixture, providing flexibility and improved performance. However, the potential for lower gas mileage due to ethanol's lower energy content is a consideration when choosing a flex-fuel vehicle.

Flex-fuel vehicles are eligible for tax credits
Although I could not find explicit information on tax credits for flex-fuel vehicles, there are a few tax incentives related to alternative fuels that may be relevant. These include:
Alternative Fuel Excise Tax Credit
The Alternative Fuel Excise Tax Credit is available to tax-exempt entities, such as state and local governments, that dispense qualified alternative fuels from an on-site fuelling station for their vehicles. To be eligible, entities must be registered with the Internal Revenue Service (IRS) and must first take the incentive as a credit against their alternative fuel tax liability. Any excess over this fuel tax liability can be claimed as a direct payment from the IRS.
Alternative Fuel Vehicle Refuelling Property Credit
The Alternative Fuel Vehicle Refuelling Property Credit is available to individuals and businesses that install qualified refuelling or recharging property for clean-burning fuel or electric vehicles. This includes charging stations for electric vehicles and bidirectional charging equipment for two- and three-wheeled electric vehicles. To qualify, the refuelling property must be installed in a qualifying location, such as a low-income community or non-urban census tract.
Now, regarding the cost of flex-fuel vehicles, there doesn't seem to be a standard price difference between regular fuel-powered cars and flex-fuel vehicles. In general, flex-fuel vehicles are designed to run on multiple types of fuel, including regular gasoline and ethanol blends. Modern flex-fuel vehicles can contain anywhere from 10 to 85% ethanol, with the rest being unleaded gasoline. While there may be some minor modifications to the engine and fuel system, flex-fuel vehicles are largely similar to their gasoline-only counterparts in terms of performance and maintenance.
The main consideration when discussing the cost of flex-fuel vehicles is the fuel efficiency and availability of flex fuels. Ethanol has lower energy density than gasoline, resulting in lower miles per gallon. However, ethanol is often cheaper than gasoline, and the savings can offset the loss in mileage. Additionally, the availability of flex fuels, such as E85 (a blend of 85% ethanol and 15% gasoline), may vary depending on your location, with a higher concentration of filling stations in certain regions, like the upper Midwest. Therefore, when considering the cost of a flex-fuel vehicle, it's important to factor in the fuel efficiency, fuel prices, and the availability of flex fuels in your area.
