The Chevrolet Volt is essentially a plug-in hybrid, meaning it has the ability to run much faster and farther under electric power alone than a normal hybrid. In the Volt's case, this means up to 100 mph and anywhere from 25-50 miles without using a drop of gasoline., , Once you run out of battery juice, the gasoline-powered inline-4 engine kicks in, producing electricity for the motor and actually powering the wheels in some circumstances, stretching the Volt's range by as much as an additional 300 miles., , The electric motor is rated at 149 horsepower (111 kilowatts) and 273 pound-feet of torque. Drive force is sent to the front wheels through a specialized planetary gearset. Standard feature highlights include a full complement of airbags, stability control, OnStar, automatic climate control, a split-folding rear seatback, a six-speaker sound system and GM's MyLink system that includes Bluetooth streaming audio, voice controls and enhanced smartphone integration. Options include a rearview camera, parking sensors, leather upholstery, heated front seats, a navigation system and a Bose sound system. Volt owners can monitor the car's status and set charging times through an online Web portal or a mobile phone app., , In our reviews, we've found that the Chevrolet Volt has satisfying zip at low speeds thanks to its electric motor, which offers abundant torque. Although the Volt corners surprisingly well due to its low center of gravity, the overall driving experience is as bland as one would expect from a car designed to maximize energy efficiency. But the Volt certainly isn't a laggard, and overall performance is similar to what you'd get from a normal four-cylinder-equipped family sedan. Acceleration is the same whether or not the gas engine is in use, but there is a noticeable (though not really objectionable) increase in noise., , Inside, the Chevy Volt features a unique dashboard layout that's part spaceship, part iPod -- and pretty darn cool. There's a high-tech gauge readout behind the steering wheel and a swoopy center stack that looks like an oversized high-end electronic device. Unfortunately, the touch-activated "buttons" can be difficult to pick out at a glance, and sometimes don't respond on first press. This is definitely an instance of form over function., , The rear seat is adequate for two average-sized adults, but there's no middle seat thanks to the T-shaped battery pack, which occupies this slot as well as part of the trunk. Cargo capacity is limited due to the Volt's rakish roof line and that hefty battery pack, though the rear seatbacks do fold down.
