Battery: This is the centerpiece of the Volt 2.0. Significant improvements in battery technology, cooling, heating and packaging is enabling GM to offer the Volt 2.0 in two different versions:
- A five-seat version (unlike the Volt 1.0, which was only available with four seats) with a 16 kWh battery. This uses the same T-shaped battery as the Volt 1.0, but there is a "cut-out" for a fifth passenger, effectively dividing the battery into two clusters -- one between the front seats, and the other under the rear seat. Viewed from under the car, it would look identical to the Volt 1.0, however. A four-seat version, just like the Volt 1.0. By filling in this space in the "tunnel," battery capacity increases from 16 kWh to 20 kWh. This version would also be a "spare part" that would also fit inside the Volt 1.0, proving the long-term upgradeability of the Volt. The battery enclosure would be identical to the Volt 1.0, preserving long-term upgradeability and spare part economics.
