The panoramic front window has a predetermined configuration that minimizes drag. ## Claims ### Claim 1 A bus including a forward cab section and a rear passenger section connected to the forward cab section with a partition wall between said sections having an enlarged central opening therein, said forward cab section having a driver compartment comprising opposed sides connected by a roof and a front cab window having an upper horizontally oriented edge having a predetermined width, said rear passenger section having a passenger compartment and a window cap unit forward of the passenger compartment that overlies the roof of the driver compartment, said window cap unit including a rearward slanted, forward-facing window that has a predetermined height of at least 18 inches and a first horizontally oriented edge that has a width dimension that is greater than a second opposed horizontally oriented edge that has a width dimension equal to or at least 90 percent of said predetermined width of said upper horizontally oriented edge of the front cab window, said forward-facing window being positioned so that said forward-facing window's second edge is adjacent the upper edge of the front cab window and is aligned centrally along a common central reference line with the front cab window to form a panoramic front window, said passenger compartment having a floor supporting seats for the passengers and a doorway on a side of the passenger section with at least one step to assist passengers to enter the passenger section, said floor positioned with respect to the panoramic window, and said predetermined height of the forward-facing window and said enlarged opening in the partition wall are all sufficiently large to enable a passenger when seated in a seat or standing on the floor and looking towards the driver compartment to see into the cab section and into the window cap unit and through the panoramic front window. ### Claim 2 (depends on 1) The bus of claim 1 where the front cab window's upper horizontally oriented edge is contiguous with or spaced from the forward-facing window's second edge by a distance no greater than 6 inches. ### Claim 3 (depends on 1) The bus of claim 1 where the enlarged opening has a top portion and a bottom portion, and the top portion is positioned with respect to the window cab unit and the bottom portion is positioned with respect to the driver compartment to enable a passenger to simultaneously look through both the window cab unit and driver compartment and see through both the front cab window and the forward-facing window. ### Claim 4 (depends on 1) The bus of claim 1 where the enlarged opening has a predetermined height and width with said height being greater than said width. ### Claim 5 (depends on 1) The bus of claim 1 where the front cab window is trapezoidal in shape and slanted rearward at an angle of from 20 to 60 degrees. ### Claim 6 (depends on 1) The bus of claim 1 where the forward-facing window is trapezoidal in shape and slanted rearward at an angle of from 40 to 60 degrees. ### Claim 7 (depends on 1) The bus of claim 1 where the forward-facing window has a convex exterior surface comprising a compound curvature with a radius of curvature along a longitudinal central axis of the front wall is from 150 to 190 degrees and along a latitudinal central axis of the front window is from 50 to 95 degrees. ### Claim 8 (depends on 1) The bus of claim 1 where the front cab window has a single curved exterior surface with a radius of curvature along a longitudinal central axis of the front wall is from 100 to 150 inches. ### Claim 9 A bus including a forward cab section and a rear passenger section separated by a partition wall having an enlarged central opening therein, said forward cab section having a driver compartment comprising opposed sides connected by a roof and a front cab window that is trapezoidal in shape and is rearward slanting, said rear passenger section having a passenger compartment and a window cap unit forward of the passenger compartment that overlies the roof of the driver compartment and has therein a forward-facing window that is trapezoidal in shape and is rearward slanting, said cab section window and said window cap unit window positioned with a shortest width dimension of each said windows adjacent each other and said windows aligned centrally along a common central reference line and forming a panoramic front window, said passenger compartment including seats for passengers positioned with respect to the panoramic window to enable a passenger when seated in a seat to see simultaneously through the enlarged opening into the cab section and into window cap unit and through the panoramic front window. ### Claim 10 (depends on 9) The bus of claim 9 where the windows are each slanted rearward at an angle of from 20 to 60 degrees. ### Claim 11 (depends on 10) The bus of claim 10 where exterior surfaces of the windows make an obtuse angle ranging from 150 to 210 degrees. ### Claim 12 (depends on 11) The bus of claim 11 where the window cap window has a convex exterior surface comprising a compound curvature with a radius of curvature along a longitudinal central axis of the front wall is from 150 to 190 degrees and along a latitudinal central axis of the front window is from 50 to 90 inches. ### Claim 13 (depends on 12) The bus of claim 12 where the front cab window has a single curved exterior surface with a radius of curvature along a longitudinal central axis of the front wall from 100 to 150 inches. ### Claim 14 A bus including a forward cab section and a rear passenger section including a forward window cap unit that overlies a roof of the forward cab section, said sections connected to enable a passenger in the rear passenger section to see into the cab section and into window cap unit and through a panoramic front window form by a rearward slanting window in a front of the cab section that has a perimeter including an upper horizontally oriented edge, and a rearward slanting window in a front of the window cap unit and located above the cab section window that has a perimeter including a lower horizontally oriented edge, said cab section window and said window cap unit window are positioned so their horizontally oriented edges are adjacent each other and said windows are aligned along a common central reference line to form said panoramic front window, the horizontally oriented edges being contiguous with or spaced from each other by a distance no greater than 6 inches, and said combined perimeters of said windows forming in outline of an hourglass shape. ### Claim 15 (depends on 14) The bus of claim 14 where the perimeter of each window is trapezoidal in shape, slants rearward at an angle of from 20 to 60 degrees, and said windows each have an exterior surface which make an obtuse angle with each other ranging from 150 to 210 degrees. ### Claim 16 (depends on 15) The bus of claim 15 where the window cap window has a convex exterior surface comprising a compound curvature with a radius of curvature along a longitudinal central axis of the front wall is from 150 to 190 inches and along a latitudinal central axis of the front window is from 50 to 95 inches, and the front cab window has a single curved exterior surface with a radius of curvature along a longitudinal central axis of the front wall is from 100 to 150 degrees.
