1. A torque box for a vehicle, the torque box comprising: first and second clamshells joined to each other at respective top and bottom edges and configured to form at least first and second enclosures with an inner joint in between, the first and second enclosures configured to provide top and bottom shear planes at the top and bottom edges, respectively, and at least first and second shear planes at the inner joint, the torque box having a socket at one end thereof, wherein the socket faces forward in the vehicle and is configured to receive an end of a crush rail of the vehicle, or an adapter for the crush rail. 2. The torque box of claim 1, wherein the inner joint is formed by a ridge on at least one of the first and second clamshells, the ridge facing another of the first and second clamshells. 3. The torque box of claim 2, wherein the inner joint comprises a substantially vertical surface separating the first and second enclosures. 4. The torque box of claim 1, wherein at least a central portion of the first enclosure has a substantially rectangular cross-section, and wherein the first shear plane is formed by a bottom of the substantially rectangular cross-section. 5. The torque box of claim 1, wherein at least a central portion of the second enclosure has a substantially rectangular cross-section, and wherein the second shear plane is formed by a top of the substantially rectangular cross-section. 6. The torque box of claim 1, wherein the respective top edges of the first and second clamshells form a top joint that traverses the top shear surface. 7. The torque box of claim 6, wherein the top joint has an angle on the top shear surface. 8. The torque box of claim 6, wherein the top joint traverses the top shear surface essentially from a corner to a diagonally opposite corner. 9. The torque box of claim 1, wherein the respective bottom edges of the first and second clamshells are arced. 10. The torque box of claim 9, wherein the bottom shear plane is formed by only one of the first and second clamshells. 11. The torque box of claim 10, wherein the one of the first and second clamshells is positioned inward in the vehicle. 12. The torque box of claim 1, further comprising an additional inner plane strengthening at least one of the first and second clamshells. 13. The torque box of claim 12, wherein the additional inner plane is attached to at least one from the group consisting of: the top shear plane, the first shear plane, the second shear plane, and the bottom shear plane. 14. The torque box of claim 1, further comprising an attachment at another end thereof, the attachment configured to attach the torque box to a side sill of the vehicle. 15. The torque box of claim 1, wherein the first and second clamshells are joined at least by an adhesive at the inner joint. 16. The torque box of claim 15, wherein the first and second clamshells are joined at least by an adhesive at the respective top and bottom edges. 17. The torque box of claim 1, wherein the respective top and bottom edges comprise flanges. 18. The torque box of claim 1, wherein the first and second clamshells are cast from aluminum. 19. The torque box of claim 1, further comprising at least one additional plane, the additional plane partially traversing the first or second enclosure. 20. The torque box of claim 1, wherein the first and second enclosures are essentially parallel to each other in extending between front and ends of the torque box. 21. The torque box of claim 1, wherein the torque box has a rear end towards a side sill, wherein the first clamshell forms a first end surface facing toward the side sill in a direction, and wherein the second clamshell forms a second end surface facing toward the side sill perpendicular to the direction.
