GM unveiled another extended range electric vehicle concept—the Cadillac Converj Concept—at the North American International Auto Show in Detroit. The four-passenger Converj concept is intended to show how GM’s extended range electric propulsion technology—which the company now calls “Voltec”—can power a luxury coupe. The Converj offers up to 40 miles of all-electric driving.

Like the Chevrolet Volt, the Cadillac Converj’s Voltec electric propulsion system comprises a 16-kWh, T-shaped lithium-ion battery, an electric drive unit, and a four-cylinder engine-generator. It uses electricity as its primary source to drive the car.
A liquid-cooled battery pack contains more than 220 lithium-ion cells. Recharge time is less than 3 hours at 240V, or about 8 hours from a 120V outlet.
The front wheel electric drive unit delivers 120 kW of power, and 370 Nm (273 lb-ft) of torque. Top speed is 100 mph.
