The European Union is about to launch a new environment in the name of strict law for the world system: it is a limit emissions of carbon dioxide in addition to pollutants emitted by vehicles.
fact, carbon dioxide, while the greenhouse is not a pollutant, but, more importantly, however, is emitted from a burning!
Let's take a simple example, consider an engine "ideal" that uses methane (CH4) as fuel and pure oxygen (O2) as combustion, the combustion of the formula is:
CH4 + 2 O2 -> 2 H2O + CO2
As you can see, carbon dioxide (CO2) is part of the combustion products of this "ideal".
So what has this nortmativa??
plans to limit the quantity (in grams) of carbon dioxide emitted for each kilometer route (g / km). From simple chemical relationship
written here above it is obvious that the only way to reduce the amount of CO2 emissions is to limit the fuel (natural gas, or as in gasoline, natural gas, LPG, etc..), Or reduce consumption of vehicles !
For this reason the new legislation is percipi more positively by the buyers of vehicle manufacturers, who enjoyed EuroX output of the new legislation to force people to buy the latest models, but now we see that (finally) forced to do everything possible to reduce consumption of their cars to list!
legislation has not yet been completed but in any case come into force in 2012, and will stipulate that a certain percentage (perhaps 65%) of vehicles made by each car emits no more than 130 g / km. That percentage should reach 100% within a few years (probably by 2015), after which the limit of 130 g / km will be further lowered (probably at 95 g / km).
Well, after the numbers change, which many would say little or nothing, do a bit 'of examples to understand how severe is this legislation.
report some models of famous cars, including the kind of engine, and its CO2 emissions.

2996 cc petrol engine (6 cylinder) from 272 hp
CO2 emissions: 244 g/CO2
BMW X5 xDrive 30d
from 2993 cc diesel engine (6 cylinder) from 235 hp
CO2 emissions: 214 g/CO2
BMW M6 4998 cc petrol engine (10 cylinders) from 507 hp
CO2 emissions: 352 g/CO2
Toyota
Prius 1.5 Hybrid Engine (1497 cc petrol and electric) 115 hp
CO2 emissions: 104 g / km
Honda Civic Hybrid
hybrid engine (1339 cc petrol and electric) to 116 HP
CO2 emissions: 109 g / km
Lexus RX450h hybrid
Engine (3310 cc six-cylinder petrol and electric) from 272 hp
CO2 emissions: 192 g / km
As you can see only the cars smaller, less powerful and equipped with latest-generation engines are able to meet the CO2 limit of 130 g / km.
A 600 with a 54 hp gasoline engine alone, but not the latest, it is not already in able to meet the limit!
please note that the only cars suitable for a family able to meet the new regulations are the Toyota Prius and Honda Civic, both equipped with hybrid engines!
This is a summary of the future of cars: by 2012 all manufacturers realizzerranno ibrdi models, as it is the only way to be within the limits imposed, and, of course, to save fuel!
It is estimated that by 2020 all cars built will be driven by a hybrid engine!
For those who did not believe, know that Porsche has already announced a hybrid version of the Panamera!
