NEW YORK ( TheStreet) -- It's being called "the world's best car" by many people who drive it -- including me -- but can it handle a 1,100 mile high-speed dash through the deserts and mountains of the American West? I'm writing about the Chevrolet Volt, the electric car with a gasoline engine as range-extender.I'm one of the still relatively few people who have put thousands of miles in the all-new Chevrolet Volt, and people often ask me: Can it handle going at a steady 73 miles per hour for over one thousand miles, up and down the hills? So I set out to prove it. The Volt is driven primarily by a combination of two electric motors, but when the battery charge has come down to 25% and you're driving fairly fast and at a steady speed, the 1.4 liter four-cylinder gasoline engine can also help provide some power, apart from its function to charge the battery. The question is whether this arrangement is enough to drive the Volt comfortably at high speeds for long periods of time, sometimes heading up mountains.
