Although the French Minister of Economy complained about the reduction in taxes when the bonus/malus system started in France, the whole scheme is only now getting some changes. How does the system work? When you purchase a car, you have to pay an additional tax (malus) if the car produces too much CO2, or you might get money back from the state (bonus) if it's below a certain amount.
You might remember that France has a tax rebate system (bonus/malus) for vehicles depending on their CO2 emissions. As in the UK and in Spain, car sales in the first trimester of 2008 have been remarkably affected. For instance, 50 percent of car sales are of vehicles under four meters long.
