Competitive Intelligence
Doing research, reverse engineering, setting design targets. Additional insight for teams thinking about making the EV transition.
Brake Bias And Stability
The very best drivers can go up to but not over the maximum lateral capability during braking and corner entry. As they smoothly come off the brakes, the lateral limit increases due to both the friction circle, and more balanced loads front/rear.
Tractive Force Graphs
This is a logic path for understanding the performance of your car in straight line acceleration. Understand the impact of gearing and power and torque curves.
Differential Effects On Vehicle Dynamics
Definitions of limited slip differential types and performance, focusing on yaw moments due to combined cornering and acceleration or braking.
Lithium-Ion Thermal Runaway
State of charge, cooling, and water-based extinguisher information to minimize the chances of battery pack overheating, fire, or explosion.
