Bucks Blog: Tips for Buying and Servicing a Used Hybrid Car

A 2007 Toyota Prius.Associated Press A 2007 Toyota Prius.

Like any used car, a used hybrid vehicle can save you money, both on the purchase price and on the insurance you carry. But there are special factors to take into account when shopping for a hybrid, beyond what you’d look for when buying a traditional used car, says John O’Dell, the “green car” editor at the automotive site Edmunds.com.

More than 2 million “conventional” gasoline-electric hybrid cars (those that don’t plug in to recharge the battery) have been sold since they first came on the market, more than a decade ago. Now, more hybrids are becoming available as used cars, offering the chance for buyers to own a fuel-efficient model at a lower price. There are an estimated 415,000 used hybrids on the market right now — mostly Toyota Prius models, since the Prius has accounted for about half of new hybrid sales, according to Edmunds.

As with any used car, it’s important to have a mechanic inspect the vehicle — but finding a mechanic knowledgeable about hybrids is critical, because the cars employ some complex technology. One source for finding knowledgeable hybrid technicians: the Auto Career Development Center, which lists qualified hybrid repair shops.

You shouldn’t assume that dealerships have trained hybrid mechanics, he said; it’s best to ask. “If they say ‘no,’ move on,” he advises.

One plus: Because hybrid cars use the electric motor to help slow the car down, a hybrid’s brakes usually last longer than those on conventional cars, Mr. O’Dell said. If maintenance records indicate frequent brake jobs, the hybrid may have been driven hard by its prior owner — so you should make sure other mechanical parts aren’t worn excessively, too.

One potential cost is a replacement battery pack for hybrids. All hybrids are required by federal regulations to carry a minimum of a 100,000-mile, eight-year battery warranty; some states, like California, require even longer warranty periods. But some tests have shown that the batteries used to power the hybrids’ electric motors last much longer. “They can last for a long time,” said Mr. O’Dell. So if a car is less than five years old and has fewer than 100,000 miles on it, battery life shouldn’t be a concern, he said.

If the car is older than five years and has more than 100,000 miles on it, you might want to factor in the potential for a battery replacement. Right now, a new replacement battery for Toyota’s 2004-9 Prius models sells for less than $2,200, Edmunds found. Honda sells replacement batteries for the 2005 to 2011 Civic hybrids for $1,700, while a replacement for a Nissan Altima hybrid runs about $4,900. However, Consumer Reports notes that battery packs can be purchased from auto salvage yards for as little as $500.

Prices for used hybrids vary by market, depending on the supply available. In Southern California, where cars are relatively plentiful and demand is strong, listings include a 2006 “base” model Prius with 58,000 miles for $16,000, and a 2008 “touring” Prius with 83,000 miles for $15,000, Mr. O’Dell says.

A new 2013 Prius, meanwhile, starts at about $24,000 and can go to about $32,000, depending on trim levels and options.

Russia Skips Hybrids in Push for Natural Gas Cars

MOSCOW — Igor A. Samarsky of the southern Russian city of Krasnodar gets fuel economy on his 1998 Lada sedan that would make a Prius owner green with environmental envy.

For all of 120 rubles — about $3.80, or a little more than a gallon of regular unleaded fuel in the United States — he can drive 140 miles. The Toyota hybrid would need three gallons of gas to drive that distance.

The only drawback in Mr. Samarsky’s mind is his wife’s lingering fear that the car, which runs on methane gas, will explode on the way to the grocery store. “My wife was afraid, but I didn’t mind,” Mr. Samarsky, a mechanic, said of the methane fuel kit he installed himself by placing a high-compression tank in the trunk and a hose snaking to the engine.

“She said, ‘I won’t drive this car, it will blow up.’ But then she saw the savings, and she calmed down.”

Gazprom, the state-owned energy monopoly better known for heating houses and powering factories in Europe, is making a bet that natural gas cars are an alluring market for future growth, at home in Russia and in other European countries that have bought its gas. All the ingredients are in place for adoption of natural gas vehicles in Russia, the world’s second-largest gas producer after the United States, with economic and environmental payoffs.

Economically, it’s no contest at the pump compared with gasoline because natural gas, whose main component is methane, is so abundant and cheap in Russia. It costs about $2 a gallon less than gasoline. (For such comparisons, compressed gas is measured by its cost for a volume containing the same amount of energy as a gallon of gasoline.)

Lax regulations in Russia have already provided a foothold for natural gas for cars. Even before the auto industry officially joined in, do-it-yourself kits were readily available. Unlike the hybrids and plug-ins produced by brand-name automobile companies, many of the natural gas cars in Russia are aftermarket conversions. In Russia, a complete system can be bought for less than $1,000 at a roadside repair shop in parts of the country where natural gas is commonly used, like the region around Krasnodar.

Natural gas fuel systems in the United States, in contrast, are handled with extraordinary care. High standards are set for the tanks of compressed gas.

An advocacy group, Natural Gas Vehicles for America, estimates certified aftermarket kits are available for about 40 models of cars and trucks and cost $12,000 to $18,000. Four factory-equipped natural gas and dual-fuel cars are for sale in the United States today: the Honda Civic NG, the Dodge Ram 2500, the Chevy Silverado and the Ford F-250.

Long-haul truckers, fleet car operators and railways are adopting methane, Dave McCurdy, president of the American Gas Association, said in a telephone interview.

In Russia, natural gas has been adopted by lower-income and rural drivers, along with farmers and operators of light-duty trucks, said Yevgeny N. Pronin, director of the National Gas Motor Association of Russia, and also an executive at Gazprom in charge of marketing gas for transportation.

Gazprom, though, would like to see wider adoption. A large Russian carmaker, Russian Machines, this year announced a policy, endorsed by Gazprom, to include natural gas systems as standard on buses and light utility trucks, like the Gazelle.

The Russian government and Gazprom, though, are just now pressing aggressively for a switch to natural gas at home, where prices are about tied with the United States as the lowest in the world.

The wholesale price for natural gas at the Henry Hub in Louisiana, a standard contract for gas in the United States, was $3.33 per million British thermal units in February; the government-set domestic natural gas tariff in Russia this year is expected to average $3.87 for the same quantity.  

This is about one-quarter of the wholesale price of natural gas in other industrialized countries, like Britain or Germany, according to a study of Russia’s gas market released by Bank of America Merrill Lynch in February, meaning vehicle owners in Russia and the United States have the most to gain from converting to natural gas from gasoline or diesel.  

The biggest issue in Russia, as it will be in any country that tries a conversion, is where drivers can refuel.

In both the United States and Russian conversions, a dashboard switch allows a driver to choose the fuel type, and most drivers keep their gasoline tanks filled as a reserve.

Green Blog: Making a Boeing 737 More Like a Prius

Green: Science

Just as some hybrid cars move at low speeds solely on electricity, Boeing 737s can be made to do the same, reducing fuel burn and emissions, according to a company called WheelTug.

An electric motor system can drive a plane to and from the airport gate, reducing fuel emissions.WheeltugAn electric motor system can drive a plane to and from the airport gate, reducing fuel emissions.

On Monday, the company announced a tentative deal to equip 20 jets of the Israeli carrier El Al with a motor system that eliminates the need for a tug to pull the plane away from the airport gate.

The company sells a pair of electric motors embedded in the aircraft’s nose wheel that can be used to back the plane away from the gate, eliminating “pushback,” and then enable it to taxi out to the runway at a speed of up to 28 miles per hour.

The motors in the nosewheel run off electricity from a small engine in the back of the plane called the auxiliary power unit, which is generally used to keep the lights on and keep the plane ventilated when the main engines are turned off.

Isaiah W. Cox, the company’s chief executive, said the savings come from not having to use one or both of the main engines to taxi; each of those burns about 13 pounds of fuel per minute, or about two gallons. The auxiliary power unit burns about 4 pounds per minute, or a little more than half a gallon. In most cases, the auxiliary power unit is running anyway, he said.

Planes can leave the gate faster if they do not have to wait for a tug. The company says that engines will sustain less damage by running less when the plane is on the ground. In taxiing, planes sometimes suck in foreign objects that damage engine blades.

Airports are often major sources of air pollution, and reducing the use of diesel-powered tugs could help reduce that as well, experts say.

Work on the system began in 1994, and the concept was tested extensively last winter at the airport in Prague. The company, which is based in Gibraltar, hopes to get certification from European and American aviation regulators in early 2013.

To lure the airlines, which are often reluctant to accept new technology, WheelTug is offering to lease the equipment and split the savings. The fuel savings will easily pay for the lease, and the savings in reduced time on the ground and less engine damage will be obvious as months go by, the company says.
