I think it was in Evo or some other mag, but I read an interesting theory on the environment and modern cars. Basically, modern cars are a dam site more heavier than there counterparts 20 years ago (im no expert so ill let someone more anorack-ish than me post kerb weights of comparible cars (Fox, e90 vs e30 please )), all weighted down by additional comforts and luxuries and safety features. These means they are all less economical because of the extra weight they are carrying around. Compare this to large 4x4's that already weight 2 tonnes and adding these luxuries has much less of an effect on weight. But the small euro boxes and family hatchbacks outnumber the massive 4x4's by a sizeable margin. So are these so called small economic cars actually that, or when you add in the sheer number of them, your talking about hundreds of thousands of small cars pulling around 25% more weight than they need to with EU safety equipment and creature comforts, burning all that extra fuel in the proccess, while the 4x4 gas guzzlers pumping out the evil CO2 are in comparitively minute numbers. Are the hoards of Fiesta and Polo and Hyundai drivers actually doing more to damage the environment in there masses than the comparitively small number of people who choose to drive around in 4x4's....? Discuss.
