Vehicles: 
Meaning, Merits, 
and Demerits
Introduction
A flexible-fuel vehicle or dual-fuel vehicle is 
an alternative fuel vehicle with an internal 
combustion engine designed to run on more 
than one fuel, usually gasoline blended with 
either ethanol or methanol fuel, and both 
fuels are stored in the same common tank.

FLEX FUEL BENEFITS
3
Cleaner for the 
Environment
A flexible-fuel vehicle or dual-fuel vehicle is 
an alternative fuel vehicle with an internal 
combustion engine designed to run on more 
than one fuel, usually gasoline blended with 
either ethanol or methanol fuel, and both 
fuels are stored in the same common tank.

Burning Facility
One of the greatest advantages of a flex-fuel 
vehicle is that is can burn whatever 
proportion of fuel mixture is in the 
combustion chamber. The car is equipped 
with electronic sensors that gauge the 
blend, and its microprocessors adjust the 
fuel injection and timing.

Advanced 
Technology
Flex-fuel vehicles are built using advanced 
technology such as electronic sensors. As 
mentioned, these technological advances 
allow your car to adjust the way it's 
operating, including detecting the fuel blend 
and making any necessary adjustments. 
Modern flex-fuel cars can contain 10 to 85 
percent ethanol.

Sustainably 
Produced
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.

Improved 
Performance
While some might argue that using an 
alternative fuel source can negatively 
impact a vehicle's performance, it can have 
the opposite effect. Flex-fuel vehicles don't 
experience a loss in performance when 
using E85 fuel.

DISADVANTAGES OF FLEX 
FUEL
9
Sole Crop Use
While it's great that flex fuel can be 
sustainably produced using corn and sugar, 
its production comes with a downside. Crops 
designed to be used for flex-fuel production 
can't be allocated to other sources. This 
could potentially drive up the price of animal 
feed.

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 they have lower gas 
mileage.
