LPG

The following guide explains the visions, aims and principles of the various behaviour changes and propulsion technologies currently being developed to reduce our dependance on fossil fuels, cut congestion and reduce emissions in the hope of a better quality of life.

LPG (Liquefied Petroleum Gas) is manufactured during the refining of crude oil, or extracted from oil or gas streams as they emerge from the ground. When LPG is used to fuel internal combustion engines, it is often referred to as autogas. In some countries, it has been used since the 1940s as an alternative fuel for spark ignition engines. More recently, it has also been used in diesel engines.

Up until very recently, whether or not a car is "green" was less important to most British motorists than the actual colour of the paint. However, the most important factor was, and still is, price. BCA - the UK's largest used car seller, has provided proof that motorists are now making the connection between the two by discovering that there is a strong demand for hybrid/electric and LPG powered cars in the used car market. In fact they are selling well above the market price for their petrol and diesel counterparts.

Our panel of expert judges used the e-factor: energy, efficiency & enthusiasm to decide on the greenest vehicles and drivers. Exhaust emissions were measured by VOSA and the driver's skill was tested in the eco-driving simulator provided by the Energy Saving Trust.
