Six years after the release of the Honda Insight — the bullet-like two-seater that was the first gasoline/electric hybrid vehicle available in the United States — high gas mileage without compromise is here to stay. Praised by motorheads and environmentalists alike, hybrids represent the most exciting advancement in personal transportation since, well, the internal-combustion engine. Spearheaded by the Toyota Prius, hybrids’ popularity surge shows that a rapidly growing number of people want to be on the cusp of the hybrid revolution. Furthermore, with skyrocketing gas prices and dwindling global oil supplies, hybrids are becoming an increasingly wise investment.
In 2004, more than 83,000 hybrids were sold. In just the first half of this year, more than 90,000 were sold; final 2005 sales may eclipse 200,000. Right now, hybrids account for less than 1 percent of the automobiles sold in the United States. But given their growth rate and the dozens of new models that will be available in the next several years — Toyota alone plans to introduce 10 more hybrid models within the next seven years — hybrids will soon have a significant share of the auto market. Already there are more hybrids in more size categories than most thought possible when the Insight arrived. Meanwhile, sales of large sport utility vehicles and trucks are dwindling.
Car-buyers also are willing to pay extra for hybrids — anywhere from $1,000 to $10,000 more than conventional vehicles. But with tax incentives for hybrids and the rising cost of gas, it’s possible to make up the low end of that hybrid premium in about five years. For example, compare a conventional vehicle with the average U.S. gas mileage of 21 miles per gallon to a 46-mpg hybrid (the average of the Accord, Civic, Escape, Insight and Prius hybrids). Assume you pay $2.20 a gallon for gasoline, with that price rising 10 cents annually (a modest estimate; inflation alone will increase prices by at least 5 cents a year). After five years, you’ll save $4,658 with a hybrid; after 10 years, $10,287. (See "Hybrid Payback," below, for more examples.)
Still, the hybrid premium can be intimidating at first glance. In a survey conducted by the Polk Center for Automotive Studies, 61 percent of those polled said the extra cost would be a deterrent to buying a hybrid. But if we’re willing to pay hundreds or thousands extra for options such as larger engines, four-wheel drive or leather seats, why not invest in a technology that will actually pay dividends for years to come?
“There are a lot of features that aren’t worth the extra cost, but people pay for them because they want those features,” says Terry Penney, technology manager for advanced vehicle technologies at the National Renewable Energy Laboratory (NREL). Penney and his team have worked to develop and improve hybrid systems since the early 1990s. “You have to take the longer view, the real cost of gas and the environmental consequences of pollution. People have recently seen how gas prices can be volatile. Oil is now about $60 a barrel — where’s it going to stop?”
At the heart of every hybrid is the tandem of an internal-combustion engine (powered by gasoline) and an electric motor (powered by batteries). In conventional vehicles, automakers size gas engines to provide enough power for peak acceleration, but that level of power isn’t needed most of the time. The addition of an electric motor allows for a smaller gas engine that uses less fuel and can run more often at its peak efficiency.
In most hybrids, when the vehicle idles, the gas engine shuts off and the electric motor is the sole source of power. The electric motor also powers the hybrid at low speeds and supplements the gas engine with extra oomph when the driver accelerates quickly.
To recharge their batteries, hybrids capture kinetic energy as the vehicle slows down, a process called regenerative braking. In conventional vehicles, this energy is lost as heat when brakes apply friction. But in hybrids, the electric motor helps slow the car and transfers some of the kinetic energy to the batteries, which store the power for future use. Hybrids’ conventional brakes kick in when needed, such as with sudden stops. Because hybrids recharge themselves, there’s no need to plug them into an electrical outlet overnight.
The 10 hybrid models available today utilize these characteristics in different ways and to varying degrees. There are gray areas among the different types, but the foremost distinction is whether or not the electric motor can operate independently from the gasoline engine. In full hybrids, the gasoline engine remains off for short periods at low speeds and the electric motor alone powers the vehicle. The net effect significantly boosts city fuel economy, and while moving in electric-only mode, these hybrids release almost zero tailpipe emissions. Full hybrids available today are those from Ford — the Escape Hybrid and the Mercury Mariner Hybrid — and those from Toyota — the Prius, Highlander Hybrid and Lexus RX 400h.
Mild hybrids have all the hybrid features except electric-only drive. The gasoline engine kicks on once the vehicle begins to move and continues running until the driver turns off the ignition. The electric motor lightens the gas engine’s load and boosts power when needed. Two of Honda’s hybrids — the Insight and Civic Hybrid — are in this category. The 2006 Civic Hybrid, though, will be a full hybrid — it will include electric-only drive at low speeds.
Some hybrids do not have smaller gasoline engines in conjunction with their electric motors. These muscle hybrids deliver improved horsepower and acceleration, with slightly improved fuel economy. They also have idle-off and regenerative braking. The main example is the Honda Accord Hybrid, which has a six-cylinder engine and delivers up to 255 horsepower with fuel economy estimates of 29 mpg in city driving and 37 mpg in highway driving. The nonhybrid Accord with a six-cylinder engine has 15 less horsepower and achieves about 21/30 mpg. Some consider the Highlander Hybrid and RX 400h muscle hybrids because of their six-cylinder engines.
Described by some as hollow hybrids, the Chevrolet Silverado Hybrid and GMC Sierra Hybrid have the most limited hybrid characteristics. These trucks do not have electric-only drive, but they do have idle-off and regenerative braking. However, their regenerative braking only recharges the batteries — the batteries do not store extra kinetic energy for use with hard acceleration. The batteries do help power on-board accessories, such as air conditioning, and plug-in devices, such as electric tools. These trucks have a net fuel economy increase of about 10 percent over their conventional counterparts.
A year ago, long waiting lists greeted those who wanted to buy just about any hybrid model. Some shoppers remained in limbo for six months or more. Demand was intense and supply was limited — looking for a hybrid became a year-round version of shopping for the hottest, hard-to-find toy of the Christmas season. Production of hybrids, though, is constantly increasing in an effort to keep up with demand. Although unsold hybrids are rare on dealers’ lots — most are spoken for before they arrive — wait time is usually just a few weeks.
High demand also has driven up the price of hybrids. Odds are you won’t successfully haggle dealers for a bargain — in high-demand areas, hybrids frequently sell for several thousand dollars more than their retail prices. Some used hybrids, especially recent years of the Prius, sell for as much or more as they cost when brand-new. That’s at least a good sign for resale value — most new cars sharply decline in value as soon as they leave dealers’ lots. To get the best deal on a hybrid, be patient and search high and low. Arm yourself with knowledge so you don’t get gouged; several Web sites list prices recently paid for automobiles. Two examples are HybridCars.com and Kelley Blue Book. Also read about others’ hybrid-buying experiences in the numerous Internet blogs and forums devoted to hybrids.
If you buy a hybrid before 2006, you can take a $2,000 deduction on your federal income taxes. Basically, this deduction will reduce your federal taxable income by $2,000. For hybrids bought after Jan. 1, 2006, the recently enacted energy bill set up tax credits — ranging from $250 to $3,400, depending on the vehicle’s fuel economy. The credit would go toward your tax liability, the amount you owe before any withholdings.
Over the long term, the credit will be more advantageous to those who buy newer hybrid models and less helpful to those who buy better-selling hybrids such as the Prius. The energy bill established a complex formula to reduce the credits once an automaker sells more than 60,000 hybrids after Jan. 1. Hybrid buyers in 14 states also can take advantage of state-level incentives, including tax credits and exemptions from sales tax. Hybrid buyers in Colorado, for example, are eligible for tax credits of more than $4,500. There also are nonfinancial incentives — such as being allowed to drive in lanes for high-occupancy vehicles and park without paying meter fees.

Owning a hybrid should be a worry-free experience — don’t believe naysayers who claim they come loaded with extra maintenance costs. Their regular maintenance needs are no different than gasoline-only vehicles, and the Honda Civic Hybrid and Toyota Prius have earned the highest ratings for reliability and owner satisfaction from Consumer Reports. In a now-famous quote within the hybrid community, Toyota mechanic Gus Heredia told the Los Angeles Times, “I’d go broke if the Prius was all I worked on.”
Hybrids also are backed by the same warranties you’d expect with any new automobile. Additional warranties cover the hybrid systems and typically last for eight years or 100,000 miles. The hybrid components do not require any routine maintenance, and the batteries will work for about 200,000 miles or more. When they do expire, they can be recycled.
Tune-ups and routine service for hybrids probably should be handled by a dealer-based mechanic — unless you know and trust an independent mechanic with hybrid experience. Dealers’ higher rates probably are worth paying to keep your hybrid in knowledgeable hands. Expect, though, to save some money on brake maintenance — regenerative braking reduces the use of mechanical brakes, extending their life.
In terms of safety, hybrids pose no more danger in a collision than any conventional vehicle. In fact, many hybrids offer the best in newer safety technologies, such as stability control, anti-lock brakes and side air bags. Here’s more good news: given those safety features, you may even save money on insurance for a hybrid, especially if you’re upgrading from an older vehicle and have a good driving record.
Initially, some hybrid owners find that their actual gas mileage doesn’t live up to what’s advertised. For many, the effort to improve their fuel economy becomes a diligent pursuit. Once drivers understand how hybrids work, they can adjust their driving habits to improve their mileage — for example, learning just when to press and release the accelerator to maximize coasting on the electric motor helps improve miles per gallon.
Consider, though, that the advertised fuel economy numbers may be slightly exaggerated. The Environmental Protection Agency (EPA) uses a 30-year-old methodology for calculating fuel economy. The tests do not account for modern influences on gas mileage such as air conditioning and speeds greater than 60 mph. The final numbers can be inflated by as much as 10 percent. (See Green Means Go.)
Properly driven hybrids, though, will match their EPA-rated fuel economy more closely than nonhybrids, according to Amory Lovins, senior author of Winning the Oil Endgame and chief executive officer of Rocky Mountain Institute, an independent, nonprofit think tank devoted to energy and resource efficiency.
Lovins recommends “pulse” driving: “When you see that you’ll need to slow or stop, start braking gently and as early as possible so you can recover the most braking energy for later use. If you brake too late — hence too hard — the mechanical brakes will override, and they simply turn motion into useless heat.”
Hybrids also are a justified excuse to accelerate with vigor. “Contrary to what we were taught in high-school driver’s education, when you’re accelerating up to cruising speed, do so briskly,” says Lovins, who owns a Honda Insight that gets 63 mpg. “The engine is most efficient at high speed and torque, so you’ll use less fuel accelerating aggressively for a short time than accelerating slowly for a long time.”
Also, take advantage of hybrids’ computerized monitors that show which components are delivering power and report your fuel economy. “Consistent with attentive driving, keep an eye on the real-time mpg display and use the feedback to improve your driving habits,” Lovins says.
Exactly how much your fuel economy will improve by driving a hybrid depends on numerous personal factors, but compared to gasoline vehicles, today’s hybrids generally get 20 percent to 25 percent better fuel economy in highway driving, and 40 percent to 100 percent better mileage in city driving. Gas mileage in high-speed driving can improve if you avoid short trips and take a road with at least some hilly sections — the electric motor will kick in with steep inclines, aiding the gas engine’s efficiency. For example, Penney — who drives a Prius — gets better results when he’s on highways in Colorado’s mountains than when driving through the city of Golden to reach the NREL office.
But stop-and-go driving does have the statistical edge. “It’s generally true that stop-and-go driving is better [for hybrids’ fuel economy] because you get regenerative braking, and that’s always better than no regenerative braking,” Penney says. “So if a hybrid is better for someone, it’s for someone who does a lot of starting and stopping.”
Translation: everyone. The bottom line is that driving a hybrid can be empowering — a personal, patriotic and environmental rush. The next time you spend $20 to $30 at the gas station, imagine not returning for another 500 miles.
