Nothing beats a Hot Wheels toy car in terms of efficiency – if you’ve got a finger to push it with, there’s no need for gas, hydrogen, or even electric power. It’s one of those overstyled little gems that comes to mind when viewing the four-passenger Chevrolet Volt, with its oversized alloy wheels, aggressive stance characterized by bulging wheel wells and nearly nonexistent overhangs, its crimefighter-ish cropped roofline, and its chiseled face. In totality, the Volt appears as a precursor to future sports or muscle cars, and may be the last thing people expect when they hear electric vehicle or hybrid. The Volt is based on a modified version of the Chevrolet Cobalt architecture.
