An aerodynamic guiding arrangement for a vehicle that includes a forward gap enclosure with an upper element and a lower element. The gap enclosure is configured to be positioned and attached proximate a forward end of the vehicle. The guiding arrangement includes a gap closure mechanism for automatically moving the forward gap enclosure from an open position to a closed position, and from a closed position to an open position, based on speed of the vehicle. Another aerodynamic guiding arrangement includes a windscreen with a top, a bottom, and a center of curvature. The windscreen curves smoothly rearward with increasing distance from a central plane, and has a reverse slope such that over a majority of the windscreen the top is farther from the center of curvature than the bottom.
