For the next generation of cars, the Honda Company is working on active aerodynamics and within a period of five years it will bring in the technology.

Active aero would be launched to get away from the high, cut off tail that typifies cars such as the Insight and forthcoming CR-Z, said Nobuki Ebisawa, Honda’s R and D managing director.

Further, for improving air flow over the roof and rear of the car this is the finest shape.

However he added that there were other solutions to reducing drag and improving aerodynamic efficiency that wouldn’t have such an upshot in the appearance of the car.
