Cadillac has surprised the Detroit show with its Converj concept, an electric luxury coupe.
Designed by Brit Simon Cox, the Cadillac Converj uses the same propulsion system as the Chevy Volt. The so-called Voltec system means that the wheels are always battery powered, offering a 40-mile range which can then be extended with a four-cylinder petrol engine charging the lithium-ion battery.
GM's product czar Bob Lutz said that the Cadillac Converj concept proves that the blueprint laid down by the Volt can be scaled up or down. In the Converj it delivers 273lb ft of torque, 120 kW of power and a 100mph top speed.
Fuel saving is further enhanced by an all-glass roof incorporating solar panels and a design that promises very good aerodynamic efficiency.
"This is proof that Cadillac can produce a smaller product" Simon Cox told Autocar. "It’s more relevant to the needs of owners without losing any presence.
"We wanted an aerodynamic profile and the cab-forward design is a very different look for Cadillac. Fuel-efficient cars don’t have to look boring and undynamic.’
