An automotive vehicle has a door adapted to pivot about a generally horizontal pivot axis, with the door including a shell defining a space surrounded by the shell. The door is pivoted upon bearings located at each end of the door. A full floating torsion bar is provided and includes a first end rotationally grounded to the door shell and a second end engaged with and rotationally locked with a bearing inserts so that the torsion bar will be subjected to torsional loading as the door is pivoted. At least a portion of the torsion bar extends along an external recess defined by the door's inner and outer panels.

An automotive vehicle according to claim 1, wherein said shell of said door comprises an outer panel joined with and spaced from an inner panel, with said inner panel defining an external recess at a lower portion of said door, and with said torsional reaction section of said torsion bar extending outside said shell along at least a portion of said external recess.3. An automotive vehicle according to claim 2, wherein said external recess extends across the entire lateral width of said door.4. An automotive vehicle according to claim 2, wherein the entirety of said torsional reaction section of said torsion bar extends outside said shell and along at least a portion of said external recess.5. An automotive vehicle according to claim 4, wherein said torsional reaction section of said torsion bar extends through a hinge bracket interposed between said shell and said hinge bearing retainer.6. An automotive vehicle according to claim 2, wherein said first end of said torsion bar is rotationally grounded to an external portion of said shell.7. An automotive vehicle according to claim 3, wherein said external recess has at least one raised section and at least one lowered section, with said torsional reaction section of said torsion bar extending not only outside said shell along at least a portion of said external recess, but also through an internal portion of said shell extending above said at least one lowered section.8. An automotive vehicle according to claim 7, wherein said first end of said torsion bar extends into and is rotationally grounded within an internal portion of said shell extending above one of said at least one lowered section.9. An automotive vehicle according to claim 7, wherein said first end of said torsion bar is rotationally grounded to an external portion of said shell.10. An automotive vehicle according to claim 1, wherein said first end of said torsion bar comprises a crank arm extending into said interior space of said shell.11. An automotive vehicle according to claim 10, wherein said crank arm is secured by a clamp mounted within the interior space of said shell.12. An automotive vehicle according to claim 1, wherein said first end of said torsion bar is rotationally grounded to said shell of said door by a mounting structure secured to said first hinge half.13. An automotive vehicle according to claim 1, wherein said mounting structure secured to said first hinge half comprises a pinch block attached to a hinge bracket incorporated in said hinge half.14. An automotive vehicle according to claim 1, wherein said mounting structure secured to said first hinge half comprises a pinch block formed integrally from a hinge bracket incorporated in said hinge half.15. An automotive vehicle according to claim 1, wherein said second pivot post slidingly engages a mating non-circular bore formed in said bearing insert.16. An automotive vehicle comprising:a vehicle body; a plurality of roadwheels located under said vehicle body; a closure panel for said body, with said closure panel comprising: a door adapted to pivot about a generally horizontal pivot axis, with said door having a shell comprised of an outer panel joined with and spaced from an inner panel, with said inner panel defining an external recess at a lower portion of said door; a hinge half attached to a first end of said door shell; a first pivot post rigidly attached to said body and operatively engaged with said hinge half; a hinge bearing retainer attached to a second end of said door and having a bearing insert housed therein; a second pivot post rigidly attached to said body, with said second pivot post engaging said bearing insert such that said second pivot post and said bearing insert are rotationally locked; and a full floating torsion bar comprising: a first end rotationally grounded to said shell of said door; a second end engaged with and rotationally locked with said bearing insert such that said torsion bar will be subjected to torsional loading as said door is pivoted; and a torsional reaction section mediate said first end and said second end, with at least a portion of said torsional reaction section extending along said external recess. 17. An automotive vehicle according to claim 16, wherein said external recess has at least one raised section and at least one lowered section, with said torsional reaction section of said torsion bar extending not only outside said shell along at least a portion of said external recess, but also through an internal portion of said shell extending above said at least one lowered section.18. An automotive vehicle according to claim 16 wherein said first end of said torsion bar comprises a crank arm extending into an interior space of said shell defined by said outer panel and said inner panel.19. A method for providing a mechanically assisted door for the body of an automotive vehicle, comprising the steps of:fabricating a door shell comprised of an outer panel joined with and spaced from an inner panel, with said inner panel defining an external recess at a hinge portion of said door; providing a hinge half attached to a first end of said door shell, with said hinge half engaging a first pivot post rigidly attached to said body; providing a hinge bearing retainer attached to a second end of said door and having a bearing insert housed therein, with said bearing insert engaging a second pivot post rigidly attached to said body such that said bearing insert is rotationally locked with respect to said body; and providing a full floating torsion bar comprising: a first end rotationally grounded to said door; a second end engaged with and rotationally locked with said bearing insert such that said torsion bar will be subjected to torsional loading as said door is pivoted; and a torsional reaction section mediate said first end and said second end, with at least a portion of said torsional reaction section extending along said external recess. 20.
