CCS/GM E-Flex project

Cadillac V-Flex Evan Mai Evan Mai presented the Cadillac V-Flex, a mid-engine electric race car that uses GM's E-Flex platform in a new configuration and advances Cadillac's art & science design language.  The race inspired proportion and layout of the V-Flex draws heavily from Le Mans prototype and F1 cars. Power would come from an electric motor with a range extending internal combustion engine. The Li-ion battery placed in the bottom center of the vehicle could be swapped from underneath the car during pit stops. Aluminum heat sinks in the rear efficiently dissipate heat away from the motor and battery while performing as a rear spoiler.  The front grille serves to communicate the Cadillac design philosophy and also serves as a functional aerodynamic enhancement.
