Built for change, but how much change?

Early in Chevy Volt production, many things were possible. For instance, GM suggested a non-plug-in Volt, a Volt that utilized super-capacitors rather than batteries, as well as a Volt that replaced its electric range extending engine with a range extending fuel cell. Likewise, different amounts of electric range have also been contemplated.
And according to recent outside analysis of the Volt, much room for change was intentionally built into the Volt platform, such as room for new advanced electronics — possibly a path to increased electric range for less money.
So, how would you change Volt 2.0?
There was a time when Frank Weber, one of the Volt’s original lead engineers, claimed that Volt electric range would always be 40 miles. Of course, Mr. Weber was later transferred and subsequently left GM altogether. Still, EV range seems a key focal point.
While GM might stick to 40 miles of range as its baseline, perhaps a new battery management system could ensure that the Volt achieves 40 miles of electric range, even in extremely hot or cold weather. Or maybe, 40 miles of EV range can eventually be squeezed out of a smaller and cheaper battery pack, thanks to advanced electronics.
Then again, should GM even stick to 40 miles?
Would reducing range to 20 miles, or increasing it to 50 miles, lift sales significantly? For instance, if a consumer averages 10 miles each one way trip and has the ability to charge between trips, such as at work, why 40 miles of range? Not only is such a consumer paying for far more battery than needed, but all that battery also weighs down fuel economy during those longer weekend trips that necessitated gasoline range extending functionality in the first place.
Therefore, might not range flexibility be the key to the Volt’s long term success?
Couple that range flexibility with a non-plug-in version and the Volt begins to take on the Prius family at all levels. I know GM has the Cruze and the Volt helps sell the Cruze, but I believe that hybrid cars like the Prius have only just scratched the surface of their potential, and eventually, the Prius will outsell cars like the Cruze and the Corolla, at least in the US. Consequently, a non-plug-in Volt could be a great way to scale up GM’s battery production and Volt family sales.
Besides, since at least 50 – 60 percent of US consumers don’t have the option of off-street parking, GM, at least I believe, will eventually need to offer choices with greater fuel efficient possibilities — 50 mpgs+ in city fuel economy — but those options can’t be limited to those with plugs when so many have no ability to regularly and easily recharge.
Of course, maybe the Volt doesn’t need any major powertrain changes. Instead, maybe the only way to make the Volt more successful is a major battery breakthrough that reduces price significantly. Until then, maybe it’s all about cosmetic changes, new telematics, or a host of new amenities.
