Nope. |
Why not? The grill is big and flat, and has huge holes in it. It looks like maybe the Jeep was designed for a lot of flow through the grill, past the motor, and out the bottom of the engine compartment and/or the wheel wells. So blocking the grill would stop that flow, resulting in a big high pressure area sitting in front of a planar surface, which could result in more drag. It isn't like a passenger car, where the grill is smaller, and the front of the car more aerodynamic to start with.
