Auto-Future's public service: Eco labels

Lately we noticed, particularly in Europe, that several manufacturers are using Eco labels and making special editions of cars that are frienly to the environment. Examples: ECO2; Ecomotion; Econetic; bluemotion... We would like to warn the interested consumer about these labels and a general lack of real improvements, unless at the expenses of safety and/or driver enjoyment.
For example, Renault uses the ECO2 label for cars with emissions of CO2 lower than 140g/km, amongst other features. Is that a really big improvement?... many cars from the competition achieve better emissions than 140g/km and don't use any Eco label...
Other example: the VW Passat bluemotion gets better fuel consumption and 136g/km by using a diesel 105hp engine(!)... wow, better call this thing the Passat blue-slowmotion...
A particular worrying example is concerned with safety: recently, tyre manufacturer Continental suggested that new low rolling resistance tyres could have bigger stoping distances loosing on safety in order to achieve lower emissions. We checked the target of these statements, the new Michelin energy saving tyres, and had a look at recent comparative tests of the Peugeot 308, one of the first cars to have the new Michelin tyres. And guess what, the Peugeot 308 performed really well in both handling and braking tests being amongst the best of its class. So, not to be worried about Michelin energy-saving tyres, but be worried about Continental's Public Relation stunts...
Finally, a word of advise on this new ECO-movement. Be carefull of claims and check the facts, as exposed with the unfortunate Continental statements. And be ready to wait a litlle bit until real energy saving technology becomes cheaper... many of the stuff BMW is using in their "Efficient dynamics" portfolio is really good and provides lower consumption and emissions without loosing driving pleasure... but it's expensive! However, expect during the next two years for several of BMW's pioneered technology to be available in mainstream cars as prices go down.
