Gene and the Machine: The shocking truth about the electric Volt

Post columnist Gene Weingarten test-drives the Chevy Volt.

So, here I am, behind the wheel. I depress the accelerator with roughly the force that I'd use to put my Honda Civic into a slow roll. The Volt bolts. Just rockets forward.

"Whoa," I blurt.

"Yeah, that's low-end pep. Electric motors hit full torque right off the bat."

This is my friend Brady Holt, who is sitting beside me. I arranged to meet him in secret minutes after picking up the car. Brady reviews automobiles for Examiner.com.

(I may be a dolt, but I am a conniving dolt.)

Unlike internal-combustion engines, Brady explains, electric motors don't need to work their way up to maximum horsepower; they deliver it instantly, giving a distinctive mettle to the pedal at start-up speeds.

Brady is staying professionally reserved, but it's clear he is thrilled at getting extended time in this intriguing, hard-to-find car. One reason it's clear is that he has a small camera and is furtively taking pictures, like the Russian ambassador from "Dr. Strangelove" who finds himself momentarily unsupervised in the Pentagon's War Room.

The car rides low and stolid, like a limo, probably because its main battery, which runs the length of the chassis (and bifurcates the rear seat, limiting the likelihood of three passengers or recumbent teenage sex) also weighs as much as a fully stocked Maytag refrigerator.

A stylized icon of that battery dominates the dashboard display. Below it is a number, which is, at the moment, "21." That number provides a constant update of how many miles remain before the battery power is exhausted and the engine kicks in.

I'm getting excited. The battery readout had been "24" exactly 1.4 miles ago. This seems to be a huge discrepancy in accuracy, suggesting a battery with only half the advertised road range -- ergo, a brazen lie, a metastatic neoplasm right at the heart and soul of the machine!

"No, it's not," Brady says.

Those figures, he says, are just momentary guesstimates that fluctuate with temperature and terrain, and that self-correct over time. GM, he says, would neither miscalculate nor misrepresent something this critical to promised performance and this easily debunked.

In a few minutes, the numbers do, in fact, align.

Rats.

Rats.

I try recoiling the wire around the crayon counterclockwise. Doesn't help. Lubricating the axle doesn't help. Powering up by subbing a nine-volt for a D-cell creates sparks but still no spin.

Rats. Rats, rats, rats.

I'm heading out to Criswell Chevrolet in Gaithersburg for a photo op. Criswell will be handing a new Volt to its first Maryland buyer. On my radio, a commercial comes on. It begins: "This is a car that is destined to change the world!"

I listen. Turns out the car it is talking about is your old clunker. It is an ad for donations to the Melwood academy.

The Volt's ad campaign, by contrast, has actually been under-selling the novelty of the car, emphasizing that the buyer is not sacrificing utility for uniqueness. Rather than touting its alternative nature, the Volt's official motto almost apologizes for it:

"It's More Car Than Electric."

Why the humility? I'm thinking maybe GM is feeling guilty because it knows a more honest slogan would have been:

"Powered by Coal."

In the mainstream media's coverage of the rollout of the Volt, the merits of electric fuel have mostly been accepted as a given, as though electricity were magic fairy dust; seldom has this attitude been subjected to the rigorous scrutiny that might be applied by, say, a grumpy reviewer with an ax to grind.

Ecologically, electric power is not, when you get right down to it, all that clean. The single largest source of America's electric power grid -- at 44.5 percent -- is coal. The second largest is another fossil fuel, natural gas. So just how green is that snazzy new Volt -- with its electric butt-warmer seats -- that's charging up in your garage?

Basically, it depends on where that garage is. If it's in California, which is big on nuclear power, your Volt is practically pristine. If it's in Pennsylvania, in coal country, not so much.

To be fair, studies have shown that even dirty coal is kinder to the atmosphere than is gasoline. And while the electric power grid is getting cleaner year by year, gasoline isn't. So the "Powered by Coal" issue isn't a huge one, except for the fact that you probably shouldn't be reading about it here for the first time. There has been more than a bit of unquestioning, rah-rah, home-team nationalism to some of the media coverage of this car.

Speaking of which, I've now arrived at Criswell Chevrolet, and the handoff of the first Volt is proceeding splendidly. There's a reporter and camera crew from Fox 5 News.

Whether by design or accident, the new owner could not have provided better PR for GM. Chuck Rogers, 63, is lanky and laconic, a no-nonsense, cowboy-squinty kind of guy. Chuck ordered the car eight months ago and has driven 70 miles from Pennsylvania to get it -- not because he's a trend junkie or a publicity seeker but because he's a retired electrical engineer. He knows.

In Channel 5's report the next day, the news anchor will blithely misinform the viewers that the Volt is the "world's first electric vehicle" before handing off to the reporter, whose enthusiastic, upbeat segment will end with Chuck Rogers driving the car away, happy as a clam.

Alas, the reporter left too soon. There was a problem with the brakes. Chuck Rogers turned the car right around and drove back into the service bay. The mechanics couldn't fix it. Chuck went home that day carless.

Washington Post writer Phil McCombs once described a cave as having "a silence so utter, so austere, you can hear the crackle of neck gristle as your head turns." It's oddly like that in the Volt when it's on pure electric power. The silence is the first thing you notice. Then, that neck gristle. You hear ambient sounds you could never make out over the noise of an engine. I'm on the George Washington Memorial Parkway, heading toward the airport, and I can hear the movement of the steering column.

New technologies often involve awkward transition. Early TV news reports read like newspaper copy with sound bites weirdly introduced by a clipped "He said." In the early days of the auto industry, a company in Michigan designed a car, called the Horsey Horseless, in which the front-mounted gas tank was a full-size, realistic horse's head. The idea was that horses wouldn't be spooked by seeing this come up beside them. (It's not clear whether this car was ever actually built, but its design survives.)

There's some of that transitional silliness in the Volt. When you start the car, there is an artificial engine noise, to make the moment seem familiar. Most peculiarly, GM has outfitted the turn-signal lever so that if you pull it back toward you, it utters a little bleat to tell unwary pedestrians an otherwise silent car is approaching. Actually, calling this a bleat is unfair to sheep; it's more like someone with a head cold clearing his sinuses.

Hork snork, it proclaims. Volt driver coming through!

Remember before the Microsoft era, back when the archetype of the computer engineer was not that of a laid-back, semi-cool, scruffy geek but that of a strait-laced, uptight, button-down IBM company man with a company haircut? Ever wonder what happened to that archetype? It's still around in the auto industry!

I'm in a room full of these guys at the monthly meeting of the Washington Automotive Press Association at a luncheon near Reagan National Airport. The journos have invited executives from GM, and from the automotive and energy-technology industries, to talk about the Volt. The place is thick with car jargon understandable to everyone but me. ("OEMs," I learn, means "original equipment manufacturers," which means "car companies.")

Someone raises an interesting point: If it is indeed possible to drive this car for months on end without using a drop of gas, might the gasoline degrade in the tank and wind up damaging the engine?

The room is silent for an instant. This is apparently a very savvy question.

Then the Volt guy answers:

"Actually, we deal with that. ..."

Impressed heads nod, mine among them.

It turns out that after many months, the Volt senses when the gas is getting too old and alerts the driver so he can have the old gas siphoned out and the tank refilled.

On the way back home, on the highway, something absolutely amazing happens: nothing. Nothing whatsoever occurs at the moment the Volt makes that apocalyptic leap from all-electric power to gas. I know it has happened because the stylized battery icon suddenly is replaced by a stylized gas-pump icon. But there is no change in ride, no discernible handoff from one power source to another. And still no sound of an engine. That comes a minute or two later -- a quiet purr, much lower than you'd expect on a highway, and, curiously, it doesn't vary as you speed up or slow down. That's because the engine isn't driving the car, it's feeding the battery at a constant rate.

It all seems so ... elegant.

This would be a good time to address an issue I'd hoped would be pivotal: This car is designed to annoy people like me, by which I mean obnoxious, proselytizing proponents of clutch-and-stick driving.

I consider Americans' love affair with the automatic transmission to be a national disgrace, symptomatic of our softness as a people. This preference is lazy, unsophisticated and dumbed-down -- as I see it, philosophically inextricable from our lard-butted, couch-potato affinity for junk food, junk TV and celebrity gossip.

The Volt doesn't come with a stick shift option. I was poised to hate it for that reason alone, if necessary -- my fallback position -- until I learned that the car, basically, has no transmission at all.

That's the nature of an electric motor drive train: It speeds up and slows down smoothly without the need for "torque mediation," a term I just made up because I don't understand the actual physics. The Volt motors are almost always operating at one gear speed. The Volt's acceleration is smooth and steady; you don't experience that familiar, momentary, squishy ebb in power during automatic-transmission gear changes.

Disrespecting this car because it doesn't have a clutch seems churlish and off-point, like disrespecting dogs because they don't have gills.

Rats.

Chuck Rogers, the guy who didn't drive away with his new Volt, finally did, four days later. Jubilantly, he informs me by phone that he made the half-electric, 70-mile trip home on one gallon of gas -- exactly, mathematically, what the Volt promises for such a trip. He loves the car. Handles like a dream, he says.

Grimly, I set off for a prearranged meeting. It is my last shot at real dirt, and I am leaving nothing to chance.

My Volt is parked in a nondescript parking garage in downtown Rosslyn. A car approaches in spooky silence, a silence that is amplified -- if such a paradox is possible -- by the close quarters. The driver parks his silver Volt next to mine.

The man is wearing a trench coat and a cowboy hat, details I would have made up if this were fiction. He has a mild face; powerful people often do. This man once guarded our nation's biggest secrets. I assure him that I will never reveal his identity to anyone. If subpoenaed for it, I say, I'll go to prison and rot there.

"I don't mind if you identify me."

Dang.

Okay, this is James Woolsey, a director of the CIA under Bill Clinton. Woolsey is one of a handful of ordinary citizens who were selected by GM months ago to test-own the Volt and privately report back to the company. They were chosen for sundry reasons, some practical, some promotional. Chef Bryan Voltaggio of Frederick got one because he owns a restaurant named Volt. Woolsey is a venture capitalist in the field of alternative energy.

This handful of people has two combined qualities no one else on Earth does: 1) extended driving experience in the Volt and 2) no financial connection to GM. They can be honest, if they feel like it.

I want this guy to feel like it. So I tell him why I've brought him to this particular place.

"We are standing in the precise location where Bob Woodward used to meet Deep Throat. This is hallowed ground, a citadel to truth. It would be sacrilege to lie to a journalist in this place, or even to withhold information."

Woolsey smiles tightly. "I can see that."

"Good. Now dish the dirt."

He looks at the car, then at me.

"Okay, there is something," he says. I nod encouragingly in my best Woodwardian manner.

"When I reach to change the radio station, if my finger grazes the dashboard, it puts the radio in 'seek' mode. They have to fix that."

My pen is poised over my notebook.

"And?"

"And that's it."

What follows is a 24-minute disquisition on the evils of our dependence on fossil fuels and on the transcendent wonderfulness of the Volt. Woolsey plans on leasing a Volt for the next two years, then buying the 2013 model, which he has been told will have an engine that can run mostly on ethanol.

Pathetically, I try one last question:

"Does the expression 'follow the money' apply here?"

"Yes," he says, "but it's kind of the opposite! Many really good new ideas lose money when first implemented. The Prius did, and the Volt will. But GM was following the short-term money for years. The Japanese invested in quality and, over time, ate their lunch. With the Volt, GM is listening to people with a longer-term view. Bravo!"

Swell.

Woolsey gets in his Volt, soundlessly starts it up and whooshes away. On his rear bumper is a sticker: "Osama bin Laden hates this car."

Sigh. I don't.

I tried my best, but I can't. What I can do, though, is leave no stone unturned. So I make an extraordinary request to GM. I ask to speak to a man seldom heard from: Andrew Farah, the chief engineer of the Volt. GM put him on the phone.

There are no restrictions on what I can ask or what he can disclose.

It's a real opportunity. In a sense, I feel I am representing not only The Washington Post, and American journalism, but also you, the consumer.

"So," I say, "I've been trying to build this electric motor. ..."

Farah listens patiently to my methodology. Finally:

"My guess is, you need to get the timing right on the brushes, the commutation point."

"Where the axles go through the safety pins?"

"Yeah, that's going to be your problem area, right there. It requires precise angular tuning."

Dubiously, I redo those contacts, but this time aligning them fanatically with a magnifying glass and tweezers, as instructed.

The motor whirs into life, a blur right from the get-go, an explosion of low-end pep. It's purring, like a Volt.
