A dual fuel car is a regular petrol-run car that is modified to run on two types of fuel, such as petrol and LPG or compressed natural gas. The two types of fuel are stored in separate tanks and the driver can switch from one system to another as needed.

What You'll Learn
Regular petrol-run cars modified to run on LPG or CNG
A dual-fuel car is a regular petrol-run car that has been modified to run on Liquid Petroleum Gas (LPG) or Compressed Natural Gas (CNG). The two types of fuel are stored in separate tanks and the engine runs on one fuel at a time. The driver can switch from one system to another as needed.
The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG). It is used mainly in Europe. The advantages of dual-fuel cars are that LPG is cheaper than petrol, so running costs are lower, and the range of the car is extended because you have two tanks of fuel, one petrol and one LPG, allowing you to drive further between refills.
The engine burns gasoline and a volatile alternate fuel such as natural gas (CNG), LPG, or hydrogen. Bi-fuel vehicles switch between gasoline and the other fuel, manually or automatically.
The Toyota Prius is a hybrid car that could be argued to be a dual-fuel car because the battery power source still feeds the car’s engine.
Dual-fuel cars are expensive to modify and require a large additional fuel tank to be fitted (usually in place of a spare tyre). However, LPG prices are only a little over half that of regular petrol, so for some buyers, the fuel savings could be substantial.

Independent fuel systems allowing the driver to switch between petrol and LPG
A dual-fuel car is a vehicle that can run on two types of fuel simultaneously. The two types of fuel are petrol and LPG (Liquid Petroleum Gas). The dual-fuel car has independent fuel systems, which means the driver can switch from one fuel system to another as needed.
The advantages of dual-fuel cars are that LPG is cheaper than petrol, so the running costs are lower, and the range of the car is extended because you have two tanks of fuel, one for petrol and one for LPG, allowing you to drive further between refills.
The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG).
The Toyota Prius is a hybrid car that could be considered a dual-fuel car because the battery power source still feeds the car’s engine.
Dual-fuel cars are slightly modified to run on LPG, or in some cases Compressed Natural Gas (CNG). Although it is a costly modification that requires a large additional fuel tank to be fitted (usually in place of a spare tyre), the fuel savings could be substantial.

Increased range due to two fuel tanks
Dual fuel cars are regular petrol-run cars, but are slightly modified to run on Liquid Petroleum Gas (LPG), or in some cases Compressed Natural Gas (CNG). LPG prices are only a little over half that of regular petrol, so for some buyers the fuel savings could be substantial.
Dual fuel cars have independent fuel systems, and the driver can switch from one system to another as needed. The range of your car is extended because you have two tanks of fuel, one petrol and one LPG, allowing you to drive further between refills.
The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG), followed by natural gas (CNG), and it is used mainly in Europe.
Dual fuel cars are not just utes. They are regular cars that can run on both petrol and LPG.
The Toyota Prius is a hybrid car that is not a dual fuel car because the battery power source still feeds the car’s engine.

Multifuel engines burning gasoline and an alternate fuel
A dual-fuel or bi-fuel car is a vehicle with a multifuel engine capable of running on two fuels stored in separate tanks. The two most common alternate fuels are Autogas (LPG) and natural gas (CNG). The engine runs on one fuel at a time, and the driver can switch between the two fuels manually or automatically.
The most common technology and alternate fuel available in the market for bi-fuel gasoline cars is Autogas (LPG), followed by natural gas (CNG), and it is used mainly in Europe.
The advantages of dual-fuel cars are that LPG is cheaper than petrol, so your running costs are lower, and the range of your car is extended because you have two tanks of fuel, one petrol and one LPG, allowing you to drive further between refills.
The Toyota hybrid Prius is a related concept to dual-fuel vehicles. It is a hybrid car that uses a battery as a power source to feed the car’s engine. The battery power source is a reusable resource, unlike petrol, diesel, or LPG.
Dual-fuel cars are regular petrol-run cars that are slightly modified to run on Liquid Petroleum Gas (LPG), or in some cases Compressed Natural Gas (CNG). Although quite an expensive modification to make and one that requires a large additional fuel tank to be fitted, LPG prices are only a little over half that of regular petrol, so for some buyers, the fuel savings could be substantial.

A dual fuel car is a regular petrol-run car that is modified to run on two types of fuel, Liquid Petroleum Gas (LPG) or Compressed Natural Gas (CNG).
The dual fuel car has independent fuel systems and the driver can switch from one system to another as needed.
The advantages are that LPG is cheaper than petrol, so your running costs are lower, and the range of your car is extended because you have two tanks of fuel, one petrol and one LPG.
Bi-fuel vehicles are vehicles with multifuel engines capable of running on two fuels and the two fuels are stored in separate tanks. The dual-fuel vehicle must burn both fuels in combination.
It is a matter of debate whether you could truly call Toyota’s hybrid Prius a dual fuel vehicle. Battery power is a reusable resource, unlike the other alternatives.
