“Less fuel, more performance”, this was the opening line at the presentation of BMW’s new eco-friendly 5 Series – the Active Hybrid 5. BMW is well known for its efforts to improve fuel consumption and lower CO2 outputs under the banner of EfficientDynamics. While such endeavours are laudable, there comes a point where a company has to take the next step towards eco-friendly motoring, beyond improving combustion. Aerodynamics and reducing weight is not enough –hybrid technology is the next step.
