A description of
the various fuels used to power some of
the most popular Cars
Petrol Cars
Petrol
engine cars are the most common car
available. They are generally cheaper
than their diesel counterparts to buy.
Petrol powered cars release carbon
dioxide into the atmosphere and burn
non-renewable energy sources. We all
know this is bad for the environment but
there are obviously some petrol cars
which are less harmful (greener) than
others.

Diesel Cars
Diesel
cars sales are on the rise in the UK as
consumers are more cost conscious and
demand more efficient vehicles. Across
Europe, diesel sale amount to nearly
half of all new vehicle sold. Diesels
operate on average 30% more fuel
efficiently than petrol powered vehicles
by using higher compression ratios and
higher combustion temperatures.

Compressed Natural Gas
Compressed
Natural Gas is a fossil fuel sourced
from reserves deep under the Earth's
surface. It has lower CO2 emissions
compared to petrol/diesel but is still a
greenhouse gas.

Bio-Diesel
Biodiesel is produced from renewable
energy sources such as rapeseed,
sunflower or soybean oil. Biodiesel is
green as it has the potential to be
carbon-neutral, that is to say all the
carbon dioxide emitted during use of the
fuel when emitted from the vehicle is
balanced by the absorption from the
atmosphere during the fuel crop’s
growth.

Ethanol Cars (E85)
Ethanol,
also known as grain alcohol is produced
from plants, usually sugar cane. The
fuel has a high octane rating which in
turn means increased engine efficiency.
Ethanol is widely used globally as a
fuel and is increasing in popularity in
Europe. A number of manufactures have
developed flexi-fuel vehicles (FFVs)
currently available on from Ford, Saab
and shortly Volvo cars.
