Since the very beginning of GM’s reinvention of the electric car, we’ve known that the automaker would eventually launch a whole range of vehicles based around its common ‘Voltec’ range-extended electric drivetrain. The first car, of course, being the new 2011 Chevrolet Volt, which is on its way to dealerships all across the country as you read this.

While any additional electric cars from GM may still be a couple of years away, we’ve already been treated to several possibilities with the striking Cadillac Converj and XTS concepts, as well as the more recent Chevrolet MPV5 concept.

Additionally, GM’s European chief, Nick Reilly, recently revealed that a group of three range-extended electric vehicles using the Voltec powertrain will eventually replace the single five-door Ampera model (Opel’s version of the Chevy Volt). These were to include a sedan, hatch and compact crossover.

Now, Car and Driver is reporting that the next-iteration of the Voltec phase-in will occur at next month’s 2011 Detroit Auto Show, where GM will reportedly unveil a new compact crossover or MPV range-extended electric car dubbed the Chevrolet Amp.

Adding further fuel to the speculation fire, earlier this month GM filed trademark applications for Chevrolet Amp and Chevrolet Strobe along with a filing for Chevrolet Sonic, which we saw was the name chosen for the Aveo’s replacement.

The story doesn’t end there as GM has also registered the domain names,,, and, the latter two being purchased just this past October.
