Beta #1 was created specifically to test and refine the suspension and drivetrain. Note that it has a partial body, a roll cage, non-Aptera seats and a conventional radiator. The first image shows the new, multi-link rear suspension (Beta #1 is AWD), the third image shows the front-wheel motor controllers and the coolant manifold, the fourth image is of the new Aptera-specific in-wheel motor features optimized connection points for power and coolant as well as showing the improved cable and hose routing.
