A vehicle has a body and at least two trailing arm suspensions, one proximate each side of the body. Each trailing arm suspension has a swing arm pivotably mounted at one end to the body and a fluid suspension extending between the swing arm and the body. A wheel is rotatably mounted to a free end of each swing arm. A power plant is provided for powering each wheel and a control system is provided for controlling a volume of fluid in each fluid suspension. The vehicle may have a longitudinally extending body with a sliding side door riding along a track configured such that said door has an open position extending transversely of said body. The vehicle may have a monocoque body with at least substantially planar sides and at least one parcel shelf extending along an inside of, and attached to, each of the sides for stiffening the sides and resisting torsion.

What is claimed is: 1. A vehicle having a pair of front wheels; a longitudinally extending body with a driver's cab extending forwardly of said front wheels and an opening forward of said front wheels for a side door; a rearwardly opening split side door for said opening comprising: an upper sliding door section above said front wheels, said upper sliding door section having a downward projection toward a forward edge thereof; an upper track extending rearwardly of said side door opening, said upper sliding side door section riding along said upper track, said track configured so that said upper sliding side door section extends longitudinally of said body both in a door closed position and in a door open position; a lower sliding door section extending below a top of said front wheels, a forward edge of said lower side door hinged to said downward projection, said lower sliding door section riding along a lower track configured such that said lower sliding door section has an open position extending transversely of said body. 2. The vehicle of claim 1 wherein said lower sliding door section is hinged at a forward end to said downward projection of said upper sliding door section. 3. The vehicle of claim 2 wherein said upper sliding door section rides along a linear track such that said upper sliding door section has an open position extending longitudinally of said body directly over said front passenger-side wheel and wherein a rearward end of said lower sliding door section rides along said lower track and said lower track is a J-shaped track. 4. A vehicle having: a pair of front wheels; a longitudinally extending body with a driver's cab extending forwardly of said front wheels and an opening forward of said front wheels for a side door; a rearwardly opening split side door for said opening, said side door comprising: an upper sliding door section above said front wheels, said upper sliding door section having a downward projection toward a forward edge thereof; an upper track extending rearwardly of said side door opening, said upper sliding side door section riding along said upper track, said track configured so that said upper sliding side door section extends longitudinally of said body both in a door closed position and in a door open position; a lower door section extending below a top edge of said front wheels, a forward edge of said lower door section attached to said projection such that opening said upper sliding side door section opens said lower door section. 5. The vehicle of claim 4 wherein said lower door section is hinged to said downward projection. 6. The vehicle of claim 5 wherein a rearward end of said lower door section rides along a J-shaped track having a forward leg extending longitudinally of said body and a rearward leg extending transversely of said body such that said lower door section has an open position extending transversely of said body. 7. The vehicle of claim 6 wherein said upper track is linear and has a length such that said upper sliding door section has an open position extending directly over said front wheels. 8. The vehicle of claim 4 further comprising a lower linear, longitudinally extending, track for guiding a front edge of said lower door section. 9. The vehicle of claim 4 further comprising a lower linear track extending below said lower door section, said downward projection projecting to said lower linear track so as to be guided by said lower linear track. 10. The vehicle of claim 4, further comprising: at least two rearward trailing arm suspensions, one proximate each side of said body, each rearward trailing arm suspension comprising a swing arm pivotably mounted at one end to said body and a fluid suspension extending between said swing arm and said body; for each rearward trailing arm suspension, a rear wheel rotatably mounted to a free end of said swing arm; a power plant for powering each said rear wheel; and a control system for controlling a volume of fluid in each said fluid suspension. 11. The vehicle of claim 10 wherein a wheel well for each said rear wheel has a sufficient height and said fluid suspension provides each said swing arm with a sufficient stroke such that said fluid suspension may allow each said rear wheel to retract until a portion of said body contacts the ground. 12. The vehicle of claim 10 wherein said fluid suspension is an air bag. 13. The vehicle of claim 10 wherein said power plant for powering each said rear wheel comprises an electric motor mounted to each said swing arm. 14. The vehicle of claim 13 wherein said at least two trailing arm suspensions comprise a driver's side rearward trailing arm suspension to which a driver's side rear wheel is mounted and a passenger's side rearward trailing arm suspension to which a passenger's side rear wheel is mounted. 15. The vehicle of claim 14 further comprising, for each rearward trailing arm suspension, a drive train between an output shaft of said electric motor supporting a pinion meshing with a face gear joined to a hub of said wheel. 16. The vehicle of claim 14 wherein each pivot mounting one end of one said swing arm of one said rearward trailing arm suspension to said body, at least while each said rearward trailing arm suspension maintains said body in a generally horizontal orientation, lies on or proximate a line between a ground contact point of each said rear wheel of said vehicle and a point of intersection of (i) a vertical line passing through a centreline of front wheels of said vehicle and (ii) a horizontal line passing through a centre of gravity of said vehicle intersects. 17. The vehicle of claim 14 wherein said body is a monocoque body. 18. The vehicle of claim 17 wherein said monocoque body has at least substantially planar sides. 19. The vehicle of claim 18 further comprising at least one parcel shelf extending along an inside of, and attached to, each of said planar sides for stiffening said planar sides and resisting deflection and torsion. 20. The vehicle of claim 17 wherein said body has a planar bottom section, a top surface of said bottom section acting as a floor. 21. The vehicle of claim 20 wherein said floor is a planar uninterrupted floor from a vehicle side door through to a vehicle rear door. 22. The vehicle of claim 20 further comprising a fin extending from a rearward edge of said planar bottom section. 23. The vehicle of claim 22 wherein said fin is pivoted at said rearward edge of said planar bottom section. 24. The vehicle of claim 23 wherein said fin has at least one wheel projecting beyond its outer edge and projecting rearwardly of a pivot axis of said fin. 25. The vehicle of claim 20 further comprising a steering linkage having a link arm and wherein said body comprises stiffening bars below said bottom section and one or more of said stiffening bars is provided with a through bore through which said link arm extends. 26. The vehicle of claim 10 wherein said body has a rear door. 27. The vehicle of claim 26 wherein said rear door opens upwardly.
