2012 Chevrolet Volt: A declaration of less dependence

By Warren Brown, Special to The Washington Post

Nature has a way of showing the interdependency of things, of bringing to naught man’s boasts of innovative triumph and, at the same time, highlighting the need for creative thinking and nobility of human spirit.

And so it happened that an unusually forceful storm roared through a wide swath of the United States late in June, toppling trees, severing branches, damaging homes and cars, and consigning several souls to eternity.

I and mine were lucky. The only thing we lost was electricity. But it was a dysfunction that lasted long enough to highlight the genius and shortcomings of the 2012 Chevrolet Volt extended-range plug-in hybrid electric car.

The Volt is a midsize four-door hatchback whose front wheels are driven by an electric motor delivering the equivalent of 149 horsepower and 273 foot-pounds of torque. The car can travel at speeds up to 100 mph for 35 to 50 miles — depending on driving style and conditions — on battery power alone.

At about 70 percent of battery discharge, the Volt’s 1.4-liter four-cylinder gasoline engine automatically takes over to keep the electric motor humming and the drive wheels turning for an additional 300 miles.

Recharging the Volt’s lithium-ion battery pack (16kWh) can take three to 15 hours — depending whether you use an available quick-charge system (240 volts) or regular house current (120 volts).

But there was no electricity at my house after the storm. I had earlier discharged the Volt’s battery pack on a meandering drive through suburban Virginia, thinking that I could recharge overnight using regular house current. But the wind and rain came and the lights went out.

The morning after, the Volt’s dashboard information screen showed “0.1 mile” of effective battery power left. I didn’t panic. The car’s information screen also showed 233 miles remaining in the Volt’s 9.3-gallon fuel tank, which requires premium gasoline.

The Volt can be driven gasoline-only as long as you’re willing to buy the gas — and as long as there is gasoline to be bought, which can be a problem if there is no electricity.

Service stations’ fuel pumps are powered by electricity. If there is no electricity, there is no gasoline. If there is no gasoline, the Volt’s generator won’t be able to generate anything to keep the Volt moving.

Suddenly, the circle of energy use and generation was completed in my mind. If there is no coal, oil or nuclear power to run electric power plants, there is no electric power. If there is no electric power, from either power plants or batteries, there isn’t much of anything else. It is a circle of dependency, of which the Volt and cars like it are an increasingly important part.

Frankly, I’d rather save oil to run the power plants, without which everything goes to pot. The Volt can help us do that, affording 35 to 50 gasoline-free driving miles in daily commuting without sacrificing longer-range trips.

There’s another thing: batteries — robust, heavy-duty, quiet-running, long-lasting batteries. Here is where creativity born of crisis comes in.

Companies such as Mitsubishi, Samsung, and East Penn Manufacturing in Lyon Station, Pa., are working on such batteries. Had they been in position at storm-struck homes and businesses, a lot of food would not have gone sour, stores would not have had to close their doors for lack of electricity, there would have been more service stations pumping gas to keep the Volt’s generator and other generators going.

Note that fossil-fuel-fed generators are great for stepping in temporarily for failed power plants. But they are absolutely noisy and, thus, lousy neighbors. Batteries that can temporarily handle heavy loads are more amenable to peaceful living.

Maybe that will be the ultimate outcome of our experiments with battery power in personal transportation. Maybe we will develop batteries that can do much, much more than power automobiles.

Bottom line: I’ve driven one pre-production and two full-production models of the Volt — in 2010, 2011 and 2012. My bottom line remains the same: It is an essential effort in the development of personal transportation that has more long-range importance than it does immediate payoff. That might make it less appealing in the marketplace considering its rather hefty price. But the payoff with this one could be more than dollars and cents.

Ride, acceleration and handling: The ride is a tad hard. But it’s adjustable with Normal (softer feel), Sport (hardest feel) and Mountain settings. Acceleration is surprisingly fast — but only to those who don’t understand that an electric motor means instant torque at the drive wheels. Whoosh! Handling is quite decent.

Head-turning quotient: This one has sharp, appealing styling. It turned heads everywhere.

Body style/layout: The Chevrolet Volt is an electrically powered, plug-in, front-wheel-drive midsize four-door hatchback. It is designed to handle most local and regional commuting on battery power only. An onboard 1.4-liter four-cylinder gasoline engine helps it to generate electric power for longer trips.

Power system: Think of it this way: Lithium-ion battery plus front-drive electric motor assisted by an internal-combustion engine to help generate electric power for longer trips. Maximum total output is equivalent to 149 horsepower and 273 foot-pounds of torque. The power system is linked to a one-speed direct-drive transmission.

Capacities: Seats for four people with tight space in the rear cabin. The fuel tank holds 9.3 gallons — premium gasoline is required.

Mileage: It depends on you. The Volt can be driven for months without using an ounce of gasoline. Stay within the 35-to-50-mile battery-only commuting range. Plug in post-commute. Resume. Gasoline alone yielded nearly 41 miles per gallon city-highway in my real-world driving.

Safety: Standard equipment includes front and rear ventilated disc brakes, four-wheel anti-lock brake protection, emergency braking assistance, electronic brake-force distribution, electronic stability and traction control, side and head air bags, and OnStar emergency communications system with trial subscription.

Price: Base price on the 2012 Chevrolet Volt is $39,145. Dealer’s invoice price on that model is $37,549. Price as tested is $43,675, including $3,680 in options (onboard navigation, rearview camera, Bose premium sound system) and an $850 destination charge. Dealer’s price as tested is $41,669. Consumer’s price can be offset by possible federal and state tax rebates up to $7,500.
