Since Buick is intended to be a more upmarket brand than Chevrolet, it seems plausible that GM could create a version of the Excelle using the Voltec (formerly E-Flex) powertrain that will propel the Volt. Most likely, GM will simply focus on the Volt and Opel/ Vauxhall Ampera for a couple of years. An ER-EV version of the Excelle will likely have to wait until the second-generation Voltec system arrives. If GM does build a Voltec based Buick will they finally revive the Electra name for it?
