BATWInG is an acronym for Baro Active Technology Wave Inducing Guide, a system created to enhance aerodynamic efficiency. The BATWInG system measures forces along the rear aerodynamic foils, then calculates and modifies the geometry of the foils in real-time to induce air pressure waves which reduce the overall wake and drag of the moving vehicle. It's a lot of math. Each wheel is propelled by a dedicated 400 HP electric motor.
To commemorate the sad end of Lego's DesignByMe,
here is the LDD development file for this model. There are small differences between the physical model and the LDD plan: The front tires are low profile, the lights are transparent pieces, and 1x2 slopes are used instead of 1x1 slopes. As of today, you can buy the bricks and elements in the LDD plan directly from Lego and make your own Electric BATWInG Batmobile, or use Lego Digital Designer to examine the model more closely and make changes to create your own custom version.
