"For instance, the LPG-powered Chevrolet Matiz S 0.8, which is available in several European countries, has a CO2 output of only 119 g/km and is among
In addition, LPG is cheaper than regular gasoline, with costs for an LPG model or for installing an LPG system, to be recovered within a few years. Chevrolet claims its models are capable of developing exactly the same power when running on LPG compared to those on fuel, so engine performances are basically the same.
The only thing that may be indeed disturbing is the LPG tank which reduce a bit the overall trunk volume. However, Chevrolet says LPG tanks are 100 percent safe, as they "undergo numerous safety and crash tests and withstand even the strongest mechanical and technical strain." In addition, an LPG tank "can withstand 2.5 times the regular gas pressure, has an pressure relief valve and overfill prevention at 80%."
There's still no information on the price difference between the LPG and gasoline/diesel versions, but keep in mind that several countries are already offering incentives and tax reductions for multiple types of less-polluting models.
