Frame member 412 curves outward in the front-to-rear direction to create a larger passenger space toward the rear of operator area 150, thereby increasing space for the driver and passenger (e.g., increasing second width W2 at B-pillars 112 and 128 increases shoulder room for the driver and passenger).

[0122] See again Figures 28 to 29, the second frame member 420 includes a first portion 422, a second portion 424, and a third portion 426. In some embodiments, the first portion 422 can be coupled to and extend forward from the lower B-pillar member 116 of the B-pillar 112, the third portion 426 can be coupled to and extend rearward from the lower A-pillar member 110 of the A-pillar 106, and the second portion 424 can be coupled between the first portion 422 and the third portion 426.

The first panel 432 includes a first edge 434 and a second edge 436, and the second panel 438 includes a first edge 440 and a second edge 442. In some embodiments, the first panel 432 is coupled to each of the first frame member 412 and the second frame member 420 on an inner side adjacent to the operator area 150, and the second panel 438 is coupled to each of the first frame member 412 and the second frame member 420 on an outer side opposite the operator area 150. In some embodiments, the first edge 434 is coupled to the first edge 440, and the second edge 436 is coupled to the second edge 442. In some embodiments, the gusset assembly 431 is assembled and coupled to the first frame member 412 and the second frame member 420 using one or more of adhesives, fasteners (e.g., bolts or rivets), and welding. The gusset assembly 431 increases the strength of the first door frame 132 by increasing the torsional strength of the first door frame 132.

[0124] Still see Figures 28 to 29 , a frame member 428 may be coupled between the upper A-pillar member 108 of the A-pillar 106 and the third portion 418, and a frame member 430 may be coupled between the third portion 418 and the lower A-pillar member 110 of the A-pillar 106. Paired diagonal plates 444 may be coupled between the frame member 428 and the third portion 418, and between the frame member 430 and the third portion 418, respectively.

[0125] See again Figures 28 to 29, a first lamp 446 and a second lamp 448 are coupled to the A-pillar 106. A first bracket 450 is coupled to the upper A-pillar member 108 of the A-pillar 106, and a second bracket 452 is coupled to the upper A-pillar member 108 of the A-pillar 106 and is vertically taller than the first bracket 450. In some embodiments, the first bracket 450 defines a hole 451, and the second bracket 452 defines a hole 453. In some embodiments, a fastener (not shown) extends through the hole 451 on the first bracket 450 and the first lamp 446 to couple the first lamp 446 to the A-pillar 106. In some embodiments, a fastener (not shown) extends through the hole 453 on the second bracket 452 and the second lamp 448 to couple the second lamp 448 to the A-pillar 106. In some embodiments, the first lamp 446 includes an adjustment assembly 454, and the second lamp 448 includes an adjustment assembly 456. In some embodiments, the adjustment assemblies 454, 456 allow the lamps 446, 448 to rotate upward and downward about a first axis A1 (e.g., a horizontal axis) to adjust the angle of the light beam (not shown) generated by the lamps 446, 448. In some embodiments, the lamps 446, 448 can rotate about a second axis A2 (e.g., a vertical axis perpendicular to the first axis A1) to adjust the angle of the light beam generated by the lamps 446, 448.

[0126] In some embodiments, the third lamp 447 ( Figure 1 ) and the fourth light 449( Figure 1 ) is coupled to the A-pillar 122 in a manner substantially similar or identical to the manner in which the first and second lamps 446 and 447 are coupled to the A-pillar 106 ( Figure 1 ).

[0127] Now see Figures 30 to 31 Frame member 464 includes a mounting portion 466, a first leg 468, and a second leg 470. A first bracket 472 is coupled to first leg 468, and first bracket 472 defines an aperture 476. A second bracket 474 is coupled to second leg 470, and second bracket 474 defines an aperture 478. A third bracket 480 is coupled to mounting portion 466, and a fourth bracket 484 is coupled to mounting portion 466 offset from third bracket 480. Third bracket 480 defines aperture 482, and fourth bracket 484 defines aperture 486.

[0128] Still see Figures 30 to 31, a bracket 488 is coupled to the member 184 of the rear frame portion 74, and the bracket 488 defines an aperture 490. A bracket 492 is coupled to the frame member 180 of the rear frame portion 74, and the bracket 492 defines an aperture 494. In some embodiments, a fastener 496 extends through the aperture 476 on the bracket 472 and the aperture 490 on the bracket 488 to couple the first leg 468 to the bracket 488 of the member 184. In some embodiments, a fastener 498 extends through the aperture 478 on the bracket 474 and the aperture 494 on the bracket 492 to couple the second leg 470 to the bracket 492 of the frame member 180.

[0129] Still see Figures 30 to 31 , the driver's rear fender 50 of the body assembly 16 is coupled to the frame member 464. In some embodiments, the driver's rear fender 50 includes a pair of holes (not shown), a fastener (not shown, such as a screw, bolt, or other fastener) extends through the hole 482, and a fastener (not shown, such as a screw, bolt, or other fastener) extends through the hole 486 to couple the frame member 464 to the driver's rear fender 50.

[0130] In some embodiments, the frame members 464 are formed from a tubular material (eg, light gauge steel), and the brackets 472 , 474 , 480 , 484 are coupled to the tubular material by welding, adhesives, fasteners, or other methods.

[0131] During operation, the vehicle 2 may be moved quickly around sharp corners and may come into contact with trees, rocks, or other obstacles that may contact, scrape, dent, or otherwise damage a body panel (e.g., body panel 50) of the body assembly 16. In some embodiments, a body panel (e.g., body panel 50) may become snagged on a tree branch or other obstacle and have a tendency to become dislodged from the vehicle 2. The frame member 464 acts as a "fuse" between the body panel (e.g., body panel 50) and the frame 14 so that when the body panel becomes snagged on an obstacle (e.g., a tree branch), the body panel separates rather than transferring force through other adjacent members (e.g., adjacent frame members or adjacent body panels). In some embodiments, under a predetermined force, one or more brackets 472, 474, 480, 484 can separate from any of the mounting portion 466, the first leg 468, or the second leg 470 to allow the driver's rear fender 50 to separate from the frame member 464, or to allow the frame member 464 to separate from the frame member 14. In some embodiments, fasteners 496 , 498 (or fasteners coupled between the frame member 464 and the driver's rear fender 50 ) may have a predetermined shear force to break to allow the driver's rear fender 50 to separate from the frame member 464 , or to allow the frame member 464 to separate from the frame member 14 .

[0132] Now see Figures 32 to 33 The vehicle 2 includes a stabilizer bar assembly 500 coupled between the left rear suspension 30 and the right rear suspension 32. The stabilizer bar assembly 500 includes a bar member 502, a first link 504 coupled to the left rear suspension 30, a second link 506 coupled to the right rear suspension 32, a first coupling member 508 coupled between the first link 504 and the bar member 502, and a second coupling member 510 coupled between the second link 506 and the bar member 502. A first mounting member 512 is coupled to the frame 14 on a first side of a longitudinal centerline L (e.g., substantially on the left side of the vehicle 2), and a second mounting member 513 is coupled to the frame 14 on a second side of the longitudinal centerline L opposite the first side (e.g., substantially on the right side of the vehicle 2). In some embodiments, each of the first and second mounting members 512, 513 defines a hole 514, within which the rod member 502 is positioned, and the rod member 502 is supported by the frame 14 via each of the first and second mounting members 512, 513. In some embodiments, a bushing or elastic member 516 is positioned within each hole 514, and the rod member 502 is positioned within and supported by each elastic member 516. In some embodiments, the first mounting member 512 is positioned laterally above the upper shock absorber mounting point 550 ( Figure 34 ), and the second mount 514 is positioned laterally outboard of the upper shock absorber mounting point 552 of the right shock absorber 62. In some embodiments, the first mount 512 is positioned laterally intermediate the lower shock absorber mounting point 554 and the upper shock absorber mounting point 550 of the left shock absorber 62, and the second mount 514 is positioned laterally intermediate the lower shock absorber mounting point 556 and the upper shock absorber mounting point 552 of the right shock absorber 62.

[0133] Still see Figures 32 to 33 Rod member 502 can be generally cylindrical, having an outer diameter, an inner diameter, and a wall thickness. Rod member 502 includes a first or middle portion 518 and a second or outer portion 524. Outer portion 524 defines a third portion 526 and a fourth portion 528, with fourth portion 528 positioned laterally outward from third portion 526. In some embodiments, first portion 518 defines a wall thickness 520 and an outer diameter 522, third portion 526 defines an outer diameter 530 and a wall thickness 532, and fourth portion 528 defines an outer diameter 534 and a wall thickness 536. In some embodiments, the wall thickness 536 of fourth portion 528 is less than the wall thickness 532 of third portion 526, and the wall thickness 520 of first portion 518 is less than the wall thickness 532 of third portion 526. In some embodiments, the outer diameter 522 of first portion 518 is less than the outer diameter 530 of third portion 526, and the outer diameter 522 of first portion 518 is less than the outer diameter 534 of third portion 526.

[0134] In some embodiments, an outer surface 538 of the outer portion 524 defines a plurality of splines (not shown), an inner surface 540 of the first coupling member 508 defines a plurality of corresponding splines (not shown), and the splines of the rod member 502 can be coupled with the splines of the first coupling member 508, such that the first coupling member 508 is rotatably coupled to the rod member 502. In some embodiments, due to reduced stress experienced at the fourth portion 528, the wall thickness 536 of the fourth portion 528 can be less than the wall thickness 532 of the third portion 526. Additionally, the wall thickness 520 of the middle portion 518 can be less than the wall thickness 532 of the third portion 526 because the third portion 526 may experience greater bending stress at the first mount 512 and the hole 514 during movement of the stabilizer bar assembly 500, and the middle portion 518 may experience greater torsional stress. In some embodiments, the stabilizer bar assembly 500 extends across a width 542 between the first coupling member 508 and the second coupling member 510, and the bar member 502 is suspended between the first mounting member 512 and the aperture 514, spanning the width 544 defined by the distance between the first mounting member 512 and the aperture 514. Each of the first mounting member 512 and the aperture 514, respectively, is positioned toward a laterally outward extent of the stabilizer bar assembly 500 to increase the amount of space available for other components (e.g., cooling system, powertrain, or other vehicle components) toward the middle of the vehicle 2 (e.g., adjacent or closer to the longitudinal centerline L). That is, the bar member 502 is suspended between a laterally outward point of the upper shock absorber mounting point 550 of the left rear shock absorber 62 and an outward point of the upper shock absorber mounting point 552 of the right rear shock absorber 62.

[0135] Now see Figures 34 to 35Shock absorber 62 extends between upper shock absorber mounting point 550 and lower shock absorber mounting point 552. In some embodiments, eyelet 570 is positioned at the upper extent of shock absorber 62. Mounting member 558 is coupled to each of frame member 180 and cross member 198. In some embodiments, mounting member 558 is a casting that defines a body 559 including: a first extension 560; a second extension 562 that is generally parallel to first extension 560; and a third extension 572 that is generally perpendicular to each of first extension 560 and second extension 562. In some embodiments, third extension 572 is coupled to each of first extension 560 and second extension 562. In some embodiments, each of first extension 560, second extension 562, and third extension 572 defines a recess 568. In some embodiments, first extension 560 defines hole 564, second extension 562 defines hole 566, eyelet 570 extends between first extension 560 and second extension 562 and is located within recess 568, a fastener (not shown) extends through holes 564, 566, and eyelet 570 around upper shock absorber mounting point 550, and shock absorber 62 is coupled to mounting member 558. In some embodiments, third extension 572 defines hole 574.

[0136] Still see Figures 34 to 35 Strap 576 may extend between trailing arm 30 and mounting member 558. Strap 576 may include a buckle 578 defining an aperture 580, and a fastener (not shown) may extend through aperture 580 and aperture 574 to couple strap 576 to mounting member 558. That is, in some embodiments, mounting member 558 includes couplings for each of shock absorber 62 and strap 576. In some embodiments, strap 576 includes a bottom buckle (not shown) located at a bottom extent, and the bottom buckle is coupled to trailing arm 30. In some embodiments, strap 576 is a stopper and prevents shock absorber 62 from extending beyond a predetermined length or travel, thereby preventing or limiting damage to shock absorber 62 during operation of vehicle 2 (e.g., during an aerial event when trailing arms 30, 32 drop under their own weight and shock absorber 62 extends to its full length). In some embodiments, strap 576 is formed from an elastic material, a high-tensile material, or other suitable material.

[0137] Still see Figures 34 to 35 , a mounting member 558 and a strap 576 are shown relative to a rear shock absorber 62 (e.g., the left rear shock absorber 62). In some embodiments, each shock absorber (e.g., the right front shock absorber 60, the left front shock absorber 60, the right rear shock absorber 62, the left rear shock absorber 62) includes a mounting member 558 and a strap 576. In some embodiments, at least one shock absorber 60, 62 includes a mounting member 558 and a strap 576.

The half-shaft 592 can be pressed toward the first bracket 582, and the first nut 596 is screwed onto the first end 598 and abuts the plate 588, coupling the half-shaft between the first bracket 582 and the second bracket 586 and preventing the half-shaft from moving during vehicle operation. However, the nut 596 can be removed with a wrench, and the half-shaft 592 can be removed to replace one of the half-shafts 234, 236. In some embodiments, the nut 594 can be located within the recessed portion 584. In some embodiments, the second end 600 is inserted into and passed through the cup 584, and the nut 594 is screwed onto the second end 600 to secure the second end 600 to the first bracket 582.
