Alas, the only car that comes close to fitting my requirements (cargo space, chargeable + hybrid tech) is the Audi A3 e-tron, which isn't available in the States yet (and it's really only a hatchback). The only other (distant) contender IMO is the Lexus RX450h, which, while roomy enough, isn't chargeable, gets not-too-stellar mileage, and is priced absurdly.
Those of us who need a commuter car with extra space that has the option (not the requirement, the option) of running on battery power for a decent stretch have been left behind. The Volt's technology would be awesome in a small SUV form factor.
Why hasn't anyone bothered to look into this?
