Has Nissan released the LEAF's drag coefficient? The Versa Hatchback's DR is 0.31, so it should be much better than that.

On the Leaf, the spoiler is not designed to create turbulent flow - otherwise it'd stick up. It's designed to create a clean edge for air traveling off the roof to separate from, minimizing drag. Look up "Kammback".garygid said:On the car, the "spoiler" basically serves the same purpose, creating turbulent flow at the LEAF's rear end.
No, it won't make a difference at all. It does not stick up at all, thus does not introduce any turbulence. It simply extends the roof-line a bit. Not to mention that the angle of the rear window is far too steep to cause any significant reduction in wake due to the introduction of turbulence. Look at the vortex generators on the roof of a Mitsubishi Evo which are specifically designed to introduce turbulence which reduces the amount of wake and thus drag - but even then the reduction in drag was minimal and the primary goal was to increase airflow to the large rear wing and increase rear downforce at speed.garygid said:The LEAF's spoiler will help create increased turbulance over the sloped back window, etc.
