Neither Chevrolet nor Nissan have felt proud enough of their EV sales numbers to list them on their latest press releases, but our colleagues over at Autoblog Green have dug those numbers up anyhow. They make for dispiriting reading if you're an electric car well-wisher, as the Volt's sales declined from January's tally of 321 to an even less impressive 281, while the Leaf closed February with only 67 US sales, down 20 on last month. Upon seeing their previous numbers, we postulated that both cars are suffering from constrained supply, which is likely still the case, but it feels ironic to us that electric vehicles, whose driving experience offers instant torque, are taking their sweet time to rev up their sales.
