Auto industry efficiency – Mercedes achieves 92 gCO/km with their new A
For a couple of years now I’ve been talking about about the power of the magic metric: a single environmental performance indicator focused on the biggest impact of a product. And how good policy based on that metric can drive a race between manufacturers to re-design their products.
Here are the latest race results in the car industry. Mercedes, a major player in auto industry efficiency, has launched its A model with Blue efficiency technology, achieving 92kgCO2/km, quite an achievement.
How they got there
* Lowering of the Cd value
* Partial covering of the upper section of the radiator grille
* Aerodynamically shaped spring link coverings improve the flow of air along the underbody at the rear axle
* Suspension lowered by 15 millimetres.
* Longer gear ratios in the higher gears (for the manual transmission model)
