LPG Prius Concept Car

Clean@auto reports from Monaco that the French Propane and Butane Federation (CFBP) and the World LP Gas Association (WLPGA) are showcasing a Prius hybrid modified to burn Liquefied Petroleum Gas (LPG) in its engine.

RM Gaz worked with the CFBP and the French Petroleum Institute (IFP) in building the Prius LPG-electric hybrid. The car delivers comparable range to the conventional hybrid, but with fewer emissions.

After all factors are considered, LPG use consumes about 5% more fuel for equivalent performance to gasoline (but it costs less).

In general, LPG yields about 50% less carbon monoxide, 40% less hydrocarbons, 35% less nitrogen oxides (NOx) and 50% less ozone forming potential compared to gasoline. The Toyota Prius LPG prototype emits only 92 g/km of CO2—11.5% less than the gasoline version.

LPG is the generic name for mixtures of propane and butane gases. The chemical composition of LP Gas can vary. Autogas—automotive LPG—generally ranges from a 30% to 99% propane mix. According to Shell, for example, in the UK autogas is predominantly propane, but the rest of Europe more commonly uses a mixture of butane and propane.

LPG is derived from crude oil refining or from natural gas or oil production. Currently, more than 60% of global LP Gas supply comes from natural gas processing plants, but the share varies substantially among regions and countries. In the US, the figure is closer to 70%. With both processes, LP Gas must be separated out from the oil product or natural gas streams.

it brings a smile to my face to finally hear toyota come out with an lpg vehicule,though i don´t understand why hybride. i live in dominican republic,where a great variaty of vehicles and models are being used with lpg do to high gas prices. i would like very much for the automobile industry to explore deeper into lpg and the great future i believe exists for all matters. i understand ford,bmw,gmc among others already have lpg motors in their line assembly but i don´t see much promotion or sales. hope this beginning won´t be slow.

Lp gas powered automobiles ,particularly three wheelers which we call in India as auto-rickshwas must be converted into lp gas for economical as well as employment and reducing air polution aspects.Unfortunately it is not being projected properly and not being understood clearly

its good to use this gas but can you give the chemical composition of auto gases so that the customer will be better understand the advantages of these gases.

good information
thank you
