Fairly pitiful, I think.

Ouch, that's pretty bad. But I wish they had published a table for analysis. That led me to this :

The Volt will achieve its 40-mile range while using only half the energy contained in its battery pack, or 8 kwh, the equivalent of the energy contained in about 1 quart of gasoline, which speaks to the efficiency of electric-drive technology. GM expects that competitive advantage in the electric-car arena will derive from a combination of battery technology and the control systems that manage the way in which batteries discharge, recharge and perform. GM has opted to produce its battery packs internally, using cells made in Korea by LG Chem. That company's U.S. subsidiary, Compact Power, won out in competition with A123 based largely on Compact Power's chemistry and safety technology.

That makes me happy because it matches my specu-calculation :



8.8 kWh = 0.24 Gallons => 4 quarts = 1 gallon.
