Can the Cadillac Converj diversify Voltec drive?

Twice the price of the Volt?

I've had conversations with many people whom already believe that the Chevy Volt is too expensive for what it offers. Thus, it appears it will, minimally, be a few generations to bring the Volt's costs down to a more mainstream figure.

Consequently, it isn't surprising that GM would try to add more models to the Flex Drive, now known as Voltec, to help spread costs. Hence, the Cadillac Converj concept.

Yet, how much can Converj help spread costs?

It's obviously a fantastic looking vehicle and it should achieve similar performance to the Volt, yet can GM really move many of these vehicles? Does the Converj offer much momentum to Voltec economies of scale?

Ultimately, I don't think so. More important, if there is a kink in Voltec, what else will GM have to offer in the interim, especially if fuel economy again reigns supreme? Full size dual mode hybrid SUVs?

Considering that there are countless things that could cause an immediate spike in gasoline prices within the next few years, is Voltec really a short-to-midterm solution? As ground breaking as the Volt is, a cheap, small 50+ mpg hybrid might have far more legs than the Volt for several more years, even a decade.

Furthermore, with the release of Ford's new electrification plans, and what we've known of Toyota's plans, the Volt and its Voltec drive are appearing less and less revolutionary each year, in addition to less comprehensive in terms of overall fleet fuel economy. And, with almost two years until the Volt officially debuts, can Voltec really be enough?
