Such a design might allow tall, boxy vehicles to optimize aerodynamics while allowing for better brake cooling when needed.

Tesla has fitted the prototype with basic aero covers, likely hiding upgraded brakes underneath. The refreshed Model Y’s launch will likely start with standard trims before the Performance variant.

When it comes to all-electric vehicles, wheels and tires make a huge difference: low-resistance tires and aerodynamic wheels increase range, and grip, and reduce noise performance. Tesla uses ...
