The sprung weight illustrated will differ from the sprung weight in HVE. In HVE the program only subtracts the wheel weight and axle weight(if solid axle) from the total weight to calculate sprung weight. We use vibration testing to estimate the total unsprung weight. This results in the sprung weight in HVE being larger than ours. E Sprung inertia is the input when building an HVE vehicle. The total inertia presented in our datasheet will differ a small amount from the value you see in HVE. When HVE calculates total inertia, it utilizes the sprung weight CGz it had calculated which per note A,B differs a small amount from sprung weight CGz in our datasheet 3 of 22

"Race Car Vehicle Dynamics" S.A.E. 1995 p 581) Wheel Center Rate that we utilize in the vehicle model is the average of the left and right side wheel positions for the front and rear.

Suspension - Auxiliary Roll Stiffness Measurement Auxiliary Roll Stiffness is the roll rate contribution by the anti-roll bar (sway bar). If the auxiliary roll stiffness is measured then the value used in the vehicle model is an average of the test values for the front and rear. If no anti-roll bar is present, auxiliary roll stiffness is assumed to be. If the auxiliary roll stiffness was not measured then it is calculated by measuring the geometry and calculating the installation ratio. This is the same procedure and formula as used by EDC Auxiliary Roll Stiffness: Front 157.5 in-lb/deg Rear 75.2 in-lb/deg Sway Bar Diameter: r1: 14. in 21. in r2: 4.5 in 6. in r3: 9.5 in 6.3 in r4: 9.5 in 15. in L: t: 24. in 62.5 in 26. in 61.8 in Aux Roll Front Rear 16 Roll Stiffness (ls/rad) 14 12 1 8 6 4 2 1 2 3 4 Test Number 9 of 22

Suspension - Damping Rate Calculation HVE uses a damping rate at the wheel. To estimate the damping rate at the wheel we first calculate the critical damping rate for the wheel. We then estimate the damping coefficient using a constant displacement vibration tester. The damping rate we use is calculated by multiplying the critical damping rate times the damping coefficient Left Front Right Front Left Rear Right Rear Damping at wheel (for HVE) 7.369 lb-s/in 7.369 lb-s/in 4.53 lb-s/in 4.53 lb-s/in Damping at Individual Wheel: 7.795 lb-s/in 6.943 lb-s/in 4.749 lb-s/in 4.256 lb-s/in Tire Rate: 3131.382 lb/in 253.83 lb/in 3131.382 lb/in 253.83 lb/in Wheel Hop Frequency: 15.8 Hz 15.6 Hz 15.7 Hz 15.8 Hz Wheel (Tire and Rim) Mass: 46.9 lb 46.9 lb 46.9 lb 46.9 lb Unsprung Mass: 132.7 lb 111.6 lb 131.5 lb 16.1 lb Sprung Mass: 982.6 lb 965. lb 691.7 lb 7.4 lb Damping Coefficient: Critical Damping Rate:.386 2.2 lb-s/in.386 18. lb-s/in.277 17.1 lb-s/in.277 15.4 lb-s/in Adhesion (%) 1 9 8 7 6 5 4 3 2 1 Adhesion ƒ hop 5 1 15 2 25 Frequency (Hz) LF Test 1 LF Test 2 LF Test 3 Hop Calculation Procedure: Unsprung Mass (m u ) Critical Damping Rate (C cr ) = 2 * Sqrt[ ((k t +k s )*(m t ))] = (k t +k s ) (2*π*f hop ) Phase LF Test 1 LF Test 2 LF Test 3 Hop Phase (rad) 2.5 2 1.5 Damping Coefficient (ζ) = 1 (2*π*f hop ) * θ Δω 1.5 5 1 15 ω(rad/s) Damping at Wheel = ζ * C cr Note: Data for Left Front Wheel is shown only F - Our damping rates will be lower than a similar vehicle's damping rate calculated by EDC since vehicles produced by EDC assume the vehicle is critically damped. 1 of 22

Suspension - Change in Half-Track vs. Jounce/Rebound Vehicle #3921 Chevrolet Equinox (2CNALBEW8A6XXXXXX) As the suspension moves through the jounce and rebound phase, the wheels could move inboard or outboard relative to the chassis. This results in a change in the track width. HVE uses half of the track width (half-track) to define this motion.

Suspension - Damping Rate Calculation Parameter Value Description Tire Rate: Appendix See White Paper HVE-WP-212-2. Wheel deflection is measured during the ride rate test using a laser sensor. Wheel Hop Frequency: Wheel (Tire and Rim) Mass: Unsprung Mass: Sprung Mass: Damping Coefficient: Critical Damping Rate: See White Paper HVE-WP-212-2. This is the frequency at which a minimum adhesion occurs between the tire and ground plane during our suspension vibration test. This is used in the calcuation of damping coefficient and unsprung mass. Wheel removed from vehicle and weighed. See White Paper HVE WP-212-2. by: (Total mass measured at the wheels) minus (unsprung mass at all four wheels) Based on the phase slope measured during our suspension test. This methodology is known as the phase-slope method. by the Equation: 2*SQRT[ (Tire Rate + Wheel Center Rate)*1)* Total Mass at the Wheel] Suspension - Camber vs. Jounce/Rebound Parameter Value Description Camber at Ride Height: using a computerized 3D wheel alignment system.

Steering - Steering System Measurements Parameter Value Description Max Wheel Angle Turns Lock to Lock: Ackermann Steering Max Steering Wheel Angle Appendix using a computerized 3D wheel alignment system. The maximum wheel angle is recorded with vehicle steered fully to the left and fully to the right. by measuring the steering wheel rotation at maximum left and right turns and dividing this by 36 degrees. The percentage of the measured total toe to toal toe based on the outisde wheel calculated with full(1%) Ackermann. Maximum steering wheel angle is measured when the steering wheel is turned lock to lock.
