• No harness attachments on SIS diagonal

• MHB-MHBS miter required

• 60C module structure testing option

• Notice of future rules development

• Phasing out side view tubes

• Reference point change

FMEA can capture the dangerous things cars may do when put in an unsafe state, and can help the team verify they meet and exceed safety regulations and requirements.

• Ride Height, Impact Attenuator, Impact Structure Heights

• Use Eyes For Harness Clips

• EV Rear Diagonal Requirement

• Get External Items off the Main Hoop and Main Hoop Braces

• High temperature knockdowns for composite and structurally bonded tractive batteries

• LV Batteries and Pressurized Cylinders must be inside the chassis

• No engine mounts on the Shoulder Harness Bar or Braces

• Maximum static ride height should be <= 75mm

Methods for a detached wheel to disable High Voltage:

• De-pin and separate outboard communication connector

• Break communication cable

• Mechanically pull apart inboard communication cable

• Steering Rack Protection

• HV Side Minimum Height

• Half-Monocoque Attachment

• Monocoque Details

They made a whole host of small changes that were almost imperceptible to the eye but aerodynamically significant. They also gave the car a nose-down rake by lowering the front suspension and raising the rear, both ever-so-slightly. All of the changes made the car significantly safer to drive at high speed. But the Ford Indigo was never going to be driven at high speeds as a show concept car – right?

• Standard Honeycomb IA

• FH Angle and Head Restraint Protection

• Tougher Monocoque Modulus and Harness

• Max 2 Tractive Battery Attachments Per Tube

• And more…

The most common barrier between your team and your performance goals is reliability. These design best practices are intended to help you create strong, stiff, and light mechanical designs. Every design requires tradeoffs, and this list is not intended to be a set of absolute rules; but it will help you identify common design strategies to follow, pitfalls to avoid, and will inform your design decision making.

Crash safety considerations beyond the frame and impact attenuator.

State of charge, cooling, and water-based extinguisher information to minimize the chances of battery pack overheating, fire, or explosion.
