Renault Twizy, the concept is built on a “skateboard” chassis, with a choice of two interchangeable “pods,” in either a passenger compartment or cargo compartment configuration.

Rinspeed plans for the “pods” to last as long as conventional car bodies, with the “skateboards” being decommissioned, recycled and replaced once they reach the end of their useful life.

Toyota

Toyota revealed its plans for a new accident avoidance system called “Guardian.” Unlike systems from Audi and Volvo, which can take control of the vehicle’s brakes and steering to mitigate accidents independent of the driver, Toyota stresses that its system will be primarily used to improve the driver’s ability to avoid accidents, requiring them to be in full control at all times.

The system will be based on “blended envelope control.” Instead of a black and white scenario in which either the driver or computer are in control, the Guardian system is designed to work collaboratively with the driver, providing minimal corrective assistance only when it senses the driver’s inability to correct an impending collision.
