Cadillac Converj Concept
The four-passenger Converj concept is intended to show how GM’s electric propulsion technology – called Voltec – can power a luxury coupe. The technology enables up to 40 miles of petrol and emissions-free electric driving with extended-range capability of hundreds of miles.
Cadillac’s extended-range electric vehicle (E-REV) concept has a new body style that is an evolution of the brand’s traditional Art and Science design theme, with an aggressive forward-leaning arc profile dominating the design.
The concept’s Voltec electric propulsion system is made up of a 16-kWh, T-shaped battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car. A thermally managed battery pack contains more than 220 lithium-ion cells that provide the primary power to drive the Converj electrically up to 40 miles without using fuel or producing tailpipe emissions. The battery is integrated into the Converj’s chassis and stores electricity from the grid when the vehicle is plugged in. It takes less than three hours to recharge the battery at 240V, or about eight hours from a 120V outlet.
