• 10.3.B.4 Each seat must have a back and a head restraint per Reg 10.3.A.13. The distance from the hip point to the top of the head restraint must be at least 800 mm for front seats and those of a single occupant solar car and at least 750 mm for rear seats.
• 10.3.B.5 Each occupant’s heels must be below their hip point.
• 10.3.B.6 The angle between each occupant’s shoulders, hips and knees must be more than 90 degrees.
• 10.3.B.7 Any additional seat padding must be positively secured to the seat.
• 10.3.C.3 The driver’s head must be above and behind the driver’s feet. The seat must be appropriately constructed with a solid base and back rest.
• Seat mounts are a critical area

Goals:

• Occupant heels will rest below heel point
• Seat padding will be foam epoxied to bell pan and backrest for driver comfort
• Angle does between occupant shoulders, hips, and knees appears to be less than 90 degrees.

Steering Wheel:

Constraints:

• 10.7.A - Must have continuous perimeter, Must be sufficiently strong to withstand loads driver may impose on it.
• 10.3.C.2 - Must be designed to minimize risk of injury to driver
• 9.4.I - Horn should be permanently mounted and operate from steering wheel
• Appendix A - Upper part above 2/3 and/or lower part below 2/3 of the circumference of steering wheel may be flat

Goals:

• Made of water-jetted 6061-T6 Aluminum should be strong enough to withstand loads.
• 3-D printed grips for driver comfort 
• Location of horn button does not interfere with steering
• Upper part above 2/3 of circumference of steering wheel is flat

Dashboard

Constraints:

• 8.6.B: BPS Fault Dash Indication The driver is to have an illuminated dash indication of a BPS fault to provide warning of an automatic opening of the Main Power Switch.
• 8.6.A.3 The power switch control location must be within easy reach of the driver and clearly labeled with the words “POWER”, “ON” and “OFF”. All letters must be 10 mm tall or larger. 
• 9.5.E.2 If equipped: the camera and view screen shall be fixed in position such that road bumps and vehicle vibration will not alter the viewing angles. 
• 9.5.E.3 If equipped: the view screen shall be positioned such that the driver shall be able to see the view screen while seated in normal driving position.

Goals:

Belly Pan

Constraints:

• 10.3.D - The cockpit must be equipped with a full belly pan to isolate the occupants from the road.
• 10.3.D - The belly pan must be strong enough to support the full weight of each occupant.

Goals:

• Isolates occupant from the road and supports driver weight.
• Matches bottom frame profile to fully separate driver from the road. Cutouts to account for seatbelt mounts.
• Plate is 1/16'' thick 4130 chromoly steel (weight considerations) 

Ballast Box

Constraints:

• 9.7.B.1 Each solar car must have one (1) ballast box for each occupant.
• 9.7.B.2 Each Ballast Box shall have a lid which is secured closed for carrying ballast. The Ballast Box(s) must be securely fastened to a structural member of the solar car and/or be demonstrated to hold the ballast fixed in the event of an impact. Each occupant’s Ballast Box shall be located within a 300 mm horizontal distance of the occupant’s hip location
• 9.7.C.1 Teams entered in the Single-Occupant class may elect to use a Common Ballast. The Common Ballast provision does not apply to drivers or passengers in MOVs.
• 9.7.C.2 Should a team elect to use a Common Ballast, then each solar car driver shall have one (1) individual ballast bag and the Common Ballast bag. The sum of the two (2) ballast bags shall be equal or greater than the ballast required to bring the driver’s weight up to 80 kg as per Reg. 11.2.
• 9.7.C.3 Teams that plan to use a Common Ballast must equip their cars with a Common Ballast Box that complies with 9.7.B.2. This box may be located anywhere within the vehicle. The Common Ballast bag will be sealed within the Common Ballast Box at the start of the event.

Goals:

• Both ballast Boxes will be Aluminum 6061-T6. One will be the common ballast.
• Integration/attachment plan: In between frame and shell. Attached to the frame via a routing clamp. The fasteners must meet minimum requirements (SAE grade 5 bolt); Ballast Box is a critical area
