Car leasing - End of an era?

Carleasingkeys_2 Desperate to cut their recent 10-figure quarterly losses, several companies announced this week that they are abandoning or partially withdrawing from the leasing market. Chrysler announced on July 29th that it was bailing out of leasing altogether. The same day, Ford told some dealers it would raise the prices on truck and SUV leases, as reported by the Wall Street Journal. And BMW announced it would tighten terms on its leases, which account for 60 percent of the company’s sales in the U.S., according to Bloomberg.

Lease contracts depend on forecasting the trade-in (aka residual) values of vehicles at the end of the lease term. And high gas prices have accelerated the depreciation on larger models in a way lessors could not have forecasted just a few years ago. Also, some models have had incentives packaged into their financing plan, known as subventing, artificially inflating residual values. As a result, many vehicles coming off lease are worth much less than the residual value resulting in massive losses for finance companies such as GMAC and Ford Motor Credit.

Chrysler notes that its dealers will still be able to offer leasing through other financial institutions. However, on the same day, JPMorgan Chase announced it would also no longer offer leases on any Chrysler models, according to the Detroit Free Press. These changes do not affect current lessees, and Chrysler says it will provide loyalty incentives to those customers who purchase a new Chrysler, Dodge, or Jeep vehicle.

So, what does this mean?
For many customers, leasing has been a means to get lower payments and afford larger, more premium vehicles than they could otherwise. Lease payments cover only the predicted amount of depreciation on a car for the duration of the lease, plus a finance charge.

Consumers will have fewer finance options going forward. While leases will still exist in some form, they may not be as readily available or marketed with the incentives that have been common.

As a result, it will be more difficult for car shoppers to extend their reach to more expensive vehicles. This creates the temptation to take on loan terms of six or seven years to afford payments on a dream car. This shifts the depreciation risk from the automaker to the consumer. Today, 60-month loans are common, stretching longer than many warranties. Pushing loan terms out further increases the likelihood customers will want to trade-in before the loan is paid, and add the debt from one car into the next, essentially leaving them paying off two cars. They also risk that if the car is stolen or destroyed, their insurance payment won’t cover the amount they still owe.

Off-lease cars have also been a valued source for used car shoppers. Off-lease models are typically in excellent condition and are usually run through a detailed inspection process. The best part? A three-year-old vehicle has already taken its greatest depreciation hit. But with fewer leases, the cars that reach used-car lots will likely become older and arguably less desirable.

What to do?
Current lessees can celebrate that they may not be paying the full cost of their vehicle’s depreciation. But, when it comes time to acquire the next model, buyers should take care to understand the true financial implications. Very likely, people will have to keep their cars longer either to pay off a longer-term loan or to accumulate a larger down payment than they might have needed in the past. And they may have to look for a car that merely meets their needs, rather than one that satisfies their wants.

As before, it pays to select your next ride based on Consumer Reports testing, reliability, safety, fuel economy, and other key factors that can be readily researched at ConsumerReports.org. (And quickly, too, using the New Car Selector.) But we also encourage shoppers to carefully consider the owner cost data, available on the model pages, which reveal the complete economic forecast, including depreciation, fuel costs, loan interest, insurance, and other factors. Then, take the time to read through either our new- or used-car buying advice. Admittedly, this is a bit of homework, but with the changing economic environment and automotive market, the car-buying test has gotten harder.

Personal picks: Small SUVs, part 2

Continuing our staff's personal insights into the August-issue small SUVs test group. (Read: Personal Picks: Small SUVs, part 1.)

Gabe Shenhar:
I really like the new turbocharged Subaru Forester 2.5XT Limited. The car marks a big step forward over the original Forester, which is not something that can be said for every redesign these days. The new Forester provides effortless acceleration, a great ride, lots of room, a quiet cabin and lots of agility. As soon as I brought it home for the first time, I showed it to my wife and made sure it fit in the garage. It would really make a nice family vehicle for us, with enough rear seat room for two growing boys—which wasn’t the case with the original Forester. But after we finished testing it, I realized that it only got 20 mpg overall (on premium to boot). The excitement suddenly waned, which is too bad.

That brings me back to the Toyota RAV4. I’ve always had a soft spot for the RAV4, ever since it pioneered the segment in 1996. Although the design is two years old now, the current generation is still a standout. It looks good, rides and handles well, has many thoughtful interior features, and is roomy inside without being bulky. Even with the V6, I won’t have to feel guilty -- it gets 22 mpg on regular. Being quick, smooth and quiet, is the icing on the cake. So, if I were shopping for one of these today, the RAV6, as we call it here, would be my top contender.

Mike Quincy: I’m in three-row seat mode right now. Every car I look at or envision taking a permanent spot in my garage has to have this feature. Why? Well, like most households, if Mom’s happy, everybody’s happy. (Likewise, if Mom’s not happy… well, you get the picture.) Mom’s not too happy right now. See, we have two small boys who like to bring friends with them when they go places. My wife drives a Camry sedan. To keep everybody safe, all the kids ride in the backseat. Hence, with two boys and only three seating positions, only one can bring a friend. Also, Mom wants a dog. And Mom wants to build a garden. And Mom likes to buy antiques. So we need a vehicle that does everything: carry people, dogs, stuff. We don’t need to go off-road and, with a set of winter tires, we don’t need AWD. And, like everybody these days, it has to get good fuel economy and can’t break the bank. She’d love a Toyota Highlander Hybrid, but they’re simply too pricey (nearly $40,000 with the third row).

What’s the best choice here? The Mazda5. It’s not a minivan, it’s not an SUV, and it’s not a wagon. But it can get done what Mom wants in her hectic life. Even a top-level Grand Touring model tops out at $24,000 (thousands less than most in the small SUV group when popularly equipped), and still gets 23 mpg overall. Exciting to drive? Well, she’s been driving that Camry for several years, which isn’t exactly a carnival on wheels, so the Mazda5 will likely feel like a new beginning. So, as it turns out, this isn’t exactly my personal pick, but it’s the pick for domestic harmony.

Clocking the Murano - Nissan, do I have permission to continue?

Nissanmuranoclock Recently, on my way to work in our Nissan Murano, I realized the clock was off by 18 minutes. I could leave it alone, but I’d rather not do math to calculate my arrival time while driving in rush-hour traffic and monitoring traffic reports. Let’s see, 7:15 plus 18 minutes means… bumper to bumper traffic on the route I just took because I missed the radio report. Arrrgh!

So, just a simple adjustment and I’d be content in the knowledge that I am not significantly late for work. Based on recent experience driving our Infiniti EX35 and Murano, I know can adjust the radio, iPod controls, climate system, and even the trip computer when moving. Other than the integrated iPod controller, these functions don’t even require using the multifunction controller and its attendant bank of buttons. So far, so good.

But adjusting the clock? Not so fast—it’s buried deep within the vehicle settings menus, and the ability to adjust it is locked down when the vehicle is in motion. Hit “Settings” and… “Clock selection” is dim until you stop. Makes total sense.

Radio and iPod: Safe to adjust when moving. The clock: Not so much.

Nissan, why is it considered appropriate to navigate through the detailed iPod menu, browsing folders and songs, while driving at 65 mph, yet a simple clock adjustment is so convoluted that I’m not allowed to do it when driving? Sure, I change iPod tracks a whole lot more frequently than I adjust the clock’s time. (The need exists at least twice a year to adjust the clock and possibly more often, as I recently discovered.) You made redundant and simple hard keys for almost everything else, and our Murano doesn’t even have navigation, so why not just drop the mobile dashboard desktop look, sadly de rigueur for a luxury car, in favor of the luxury of simplicity? Or, just let me adjust the clock with the current, high-tech setup.

Personal picks: Small SUVs

Smallsuvsroadtest In the August issue, we tested several right-sized SUVs that represent where many buyers are heading: smaller and more fuel efficient. Among this group, the empirical standout was the redesigned Subaru Forester. It not only bested the other small SUVs in this month's small SUV Ratings (available to subscribers), its turbocharged and nonturbocharged versions also leapfrogged over the six- and four-cylinder versions of the Toyota RAV4.

We also tested the new Nissan Rogue and the four-cylinder Mitsubishi Outlander, plus we evaluated a couple old-school SUVs, the Kia Sorento and the redesigned Jeep Liberty.

To look behind the published ratings and road test, we offer personal insights on our picks for downsized SUVs:

Tom Mutchler: Even though I’m a big fan of wagons and hatchbacks, the Forester makes all of those cars in Subaru’s line-up redundant. (Same goes for the less-than-optimized Tribeca SUV.) The Forester has more room inside than an Outback wagon, and if you forego alloy wheels and heated seats, it’s less money than the smaller Outback Sport. You’re not giving up much in fuel economy or driving characteristics, either.

The Forester appeals to me because it is a refreshingly honest car. It stresses substance— like fantastic visibility, the ride/handling balance, interior space, and crash-test results— over flash. No, it doesn’t get the fuel economy of a Toyota RAV4 and it’s not as well trimmed as a Honda CR-V. But I’ll take the savings and get the more practical Forester.

One more thing: this month’s test revealed an overlooked player in this market, the Mitsubishi Outlander. It got me to the airport in an early morning snowstorm without any drama, and the huge interior easily swallowed a large laundry dryer, aided by its clever little tailgate. The steering is tuned toward sporty, and the newly-available four-cylinder is willing (if not overly powerful). While it’s likely to depreciate more than a three-year-old RAV4/ CR-V/Forester, the Outlander could make be a used-car bargain down the road.

Rick Small: The popular small SUV market is growing rapidly. These right-sized vehicles have many advantages over the older truck-based models, such as better ride, handling, and fuel efficiency. They’re also very roomy for their size; folding rear seats only add to there usefulness. Some offer third-row seats but they are mostly for small kids. The new Subaru Forester is larger and much improved over the previous model. The turbo version is more responsive and better equipped than the base, but gets two fewer mpg. Subarus all come with standard AWD, so they get less mpg than most base vehcles in this class —almost all competing models also offer FWD version. The Honda CR-V is reliable and gets better fuel economy. But I need a 3,500-pound towing capacity, which leaves the four-cylinder models off my list. The Hyundai Santa Fe and Toyota RAV4 offer V6s that will tow and the new Mitsubishi Outlander has a standard V6 that can also tow the weight I haul. Of these, the Outlander is the sportiest of the group and it fits my 6' 3" frame the best as well—although my wife complains about the lack of leg room. The RAV4 is a good choice and gets good mileage even with the V6 (22 mpg), but the driver’s seat is a bit small and flat for me. My favorite, though, is still the Nissan Murano (admittedly a bit more expensive). But it’s quicker, bigger and sportier than most of these and still manages to get 19 mpg. The new redesign is not quite as sporty as the old one, but it rides better and has more safety features.

Life in the car pool lane

Car pool city traffic With elevated gas prices, many commuters are looking at alternatives to save money.  Some people are opting to downsize their vehicle to a smaller more fuel-efficient car, others are moving to two-wheeled transportation such as motorcycles and scooters, and many other commuters are choosing to forfeit the car and take public transportation.  However, for those who can’t change their means of transportation or don’t have access to public transit, a car pool can be a great way to save money by sharing gas and toll costs, providing driving companionship, and, when you alternate driving, saving wear and tear on your car.

To gauge the impact gasoline prices have had on American motorists, the Consumer Reports National Research Center recently conducted a random, nationwide Auto Pulse survey. Among the findings, drivers have modified their transportation patterns to save money, reporting they have: Walked or bicycled more  (31%), carpooled more (24%), and worked from home (18%). Many more, at 59 percent, said that have driven slower, more smoothly. To save at the pump, combining these elements could significantly lower fuel expenses. While many drivers may not have the flexibility to walk to the office or work from home, driving more smoothly and carpooling are viable options.

What is your PMPG?
There’s a new buzzword that is being used for carpoolers to calculate the fuel savings, called Person or Passenger Miles Per Gallon (PMPG), which determines how many people are in the car compared with the vehicle’s miles per gallon. So, if your vehicle gets 22 mpg, and there are four people in your car pool, your PMPG would be significantly better than driving alone at 22 mpg—though it wouldn’t truly be four times better, as the extra passenger and possibly cargo weight will decrease fuel economy. 

If you decide that a car pool is for you, here are some tips to ensure a successful ride share.

  • Establish an efficient route and pickup/drop off times.
  • Decide who will drive and how often, setting a daily, weekly or monthly schedule.
  • Be on time or decide how long you will wait for a passenger.
  • Establish policies such as smoking or non-smoking, music and volume, food and drinks, and cell-phone use.
  • Determine the purpose. If the ride share is for commuting purposes, don’t make unscheduled stops or errands.
  • Keep your vehicle in good condition by maintaining your car and keeping the interior clean and comfortable.
  • Determine the method and frequency of payment for tolls and gasoline up front. Consider alternating driving days to ensure vehicle wear and tear is fair for all.
  • Discuss contact methods if a car pooler or driver is sick or on vacation.

There are a number of Web sites that offer ride share programs that match you with others in your area. Some examples are NuRide.com, eRideShare.com, and RideSearch.com. Just Google "car pooling" and you’ll find a number of sites from which to choose.  Also, check with your company’s HR department to find out if they have a car pooling program or company van for employees.

Comparing mileage: Not all mpg's are created equal

Fuel_pump When thinking about saving gas, it's useful to remember that not all mpg's are created equal.

Among very fuel-efficient cars, the incremental savings for every extra mpg is small. However, among very inefficient cars, even a 1 mpg savings can be significant.

Researchers at Duke University Fuqua School of Business recently released a study showing that consumers often make poor decisions when it comes to fuel savings.

For example, consider a family that owns a Chevrolet Tahoe as a family vehicle and a Toyota Camry as a commuter car. The Tahoe gets 14 mpg and the Camry four-cylinder gets 24 mpg, according to Consumer Reports testing. (Mileage figures used to illustrate the mpg mathematics are based on late-model cars.) Assume each vehicle is driven the national average of 12,000 miles per year. In an effort to save fuel, the family might be tempted to buy a high-mileage hybrid. To maintain the convenience of the Tahoe, they consider trading in the Camry for a Honda Civic Hybrid that gets 37 mpg—a 13 mpg improvement. This transaction would save them 176 gallons of fuel a year. At $4 a gallon, that would be a savings of about $700 in gas alone.

MPG Gallons per 100 miles Fuel cost for 12,000 miles Cost savings from 5 mpg gain
10 10 $4,800
15 6.67 $3,200 $1,600
20 5.00 $2,400 $800
25 4.00 $1,920 $480
30 3.33 $1,600 $320
35 2.86 $1,371 $229
40 2.50 $1,200 $171
45 2.22 $1,067 $133
50 2.00 $960 $107

But the savings could be even greater if they considered replacing the Tahoe with a Toyota Highlander that still seats seven and gets 18 mpg. While that’s only a 4 mpg improvement, the total savings in replacing the gas-guzzling Tahoe would be 190 gallons a year, or $762 in fuel.

While the Civic Hybrid might yield better bragging rights, differences of a few miles per gallon are amplified with cars that get poor fuel economy, while cars that get good fuel economy face diminishing returns for each additional mile per gallon. Of course, when considering downsizing, it is important to look at the complete owner cost situation, as trading in too soon (say, mid-way through a loan term) may not be the best deal in the long run. (Read “When to downsize your car.”)

To help consumers make better comparisons, the Duke researchers propose comparing fuel consumption—gallons per mile—rather than fuel economy in miles per gallon. This would help consumers make more direct comparisons between fuel costs, emissions, and a car’s contribution to global warming or global oil consumption.

In addition to our fuel economy measurements, Consumer Reports also translates that into annual fuel consumption and costs in our model pages, available through pulldown menus on the major Cars pages and through the New Car Selector.

The chart embedded in this post illustrates the numbers, based on rounding the current national gasoline price average of $4.06. To look at this in a different way, try the university's "The mpg illusion" interactive quiz.

This Duke study shows the importance of knowing how numbers translate into real dollars and supports the notion that it is key to factor the total owner costs when considering buying a new vehicle, especially if pain at the pump is the prime motivator. Ultimately, every gallon saved helps not only your wallet, but also aids national conservation and benefits the environment. Just make sure you understand the full picture before you buy that next car.

Small pickup truck crash tests - Some results are dismal

Coloradocrashtestside For the first time, the Insurance Institute for Highway Safety (IIHS) has tested side-impact protection on small pickup trucks and the results are not favorable. (Learn about how the IIHS crash tests cars.) The Toyota Tacoma was the only pickup to earn the highest rating of good in the side test for occupant protection. The Dodge Dakota, Mitsubishi Raider, Ford Ranger, Mazda B Series, and Nissan Frontier all rated marginal; the Chevrolet Colorado and GMC Canyon rated poor in the side test, which simulates a side impact from an SUV or pickup.

The side-impact tests are important as it’s the second most common type of crash fatality. Side air bags are standard on more than 65 percent of new models and manufacturers are working to make them standard by the 2010 model year. A federal mandate on side air bags goes into effect for the 2015 model year.

Dodgedakotafrontcrash Small pickups have the highest driver death rates of all vehicles and most occur in single-vehicle crashes and rollovers. Electronic stability control (ESC) is a key proven safety feature that can help prevent crashes and save lives, but the Toyota Tacoma and Nissan Frontier are the only pickups in this group that offer optional ESC. The 2009 version of the Tacoma, Colorado, and Canyon will come with standard ESC.

Getting the most out of that new car, part 2

2008fordfocusnew_2 In the first installment, we offered tips for new-car owners to help them get the most from their shiny new vehicle, starting with initial inspection, studying the owner's manual, and essential road gear. Here, we continue with advice on proactive car care and maintenance schedule to ensure the car continues to look and run like new.

Pamper your car
Extending brake life. Like any wear item, brake pads and components will last a lot longer if you don't use them more than necessary. Stay at least three seconds behind the vehicles ahead (that's one-one thousand, two-one thousand, etc.). At this distance, you can react calmly to changes in traffic speed and have enough space to manage an abrupt stop, if necessary. Lift your foot off the gas pedal when you see a red light in the distance or cars bunching up, rather than accelerate till the point you must brake. Keeping a safe distance from other vehicles will save gas, reduce your chances for a front and rear collision, lower the number of stones and other flying debris hitting your hood and windshield, and eliminate those herky-jerky motions that make your passengers wish they had taken the bus.

Avoiding dings. When heading to the mall or supermarket, scout out a parking location where your vehicle isn't going to be battered by shopping carts and car doors. That usually means parking well away from other vehicles. The extra walk will do you good, and you won't risk tearing off your bumper as you try squeezing in between that SUV and a Winnebago.

Preserving tires and rims. Hitting a curb can do wonders for those fancy, $500 factory alloy rims and $300 tires. So be extra careful when parking and making U-turns, or at minimum, you'll face the shame of a scratched rim.

Don't skimp on maintenance
It's a lot easier keeping your car looking and running like new than it is to resurrect it once it's a rusting hulk.

Clean everything. When washing the car, don't forget the bottom of the car and the wheel wells. Occasionally wipe the door sills clean too and the inside of the gas filler door. And don't let corrosive bird droppings linger. Beyond being unsightly, they can damage the paint.

Going after the small things. Attack the smallest of stains immediately with automotive seat and rug cleaners. For deep scratches, use a sparse layer of touch-up paint. Once dry, try blending it with the adjacent finish by rubbing with a liquid auto scratch remover. For about $100, a professional paintless dent repair shop can literally massage away door and fender dings—as long as the paint isn'€™t damaged. Do-it-yourself kits are cheaper, though less-effective.

Maintenance matters. Scheduled maintenance is critical for preventing problems and for catching little ones before they require expensive repairs. But be wary of dealer-promoted "generic" maintenance packages. There's no need to pay $389 to make sure you have plenty of windshield washer fluid. Also, the packages sometimes replace required procedures with unnecessary ones. Instead, consult the maintenance schedules in your vehicle owner's manual. Make of list of the big items you can't do yourself and then get quotes for just those. You don'€™t have to have a dealer do the work. And be sure to keep receipts.

Do-it-yourselfers should considering buying a shop manual written specifically for their vehicle, either by the manufacturers or an aftermarket publisher such as Haynes. Owners of brand-new models may have to wait several months for a comprehensive consumer manual to be written.

Technical Service Bulletins. While you're happily driving around, your car's manufacturer is collecting grizzly details about all the components that will likely break, clunk, rattle, leak, peel, or simply fall off prematurely. Though safety-related issues trigger recalls, manufacturers use so-called technical service bulletins to quietly communicate the other problems to dealers. You can see a list of these for your car and order free copies at the National Highway Traffic Safety Administration's Web site. TSBs can give you an idea about what to watch for during the warranty period, and these are items to discuss with your mechanic to ensure your vehicle is up to date with after-sales fixes.

Dangers of hot cars

Summer is in full swing and that means it's not only hot outside, but the temperature inside your car can be life-threatening. Each year, an average of 36 children die from hyperthermia after being left inside a hot car. At least 20 infants and children have died so far this year, according to a recent study by San Francisco State University (SFSU). In 2007, there were 35 fatalities. The ages range from infants to 13 years old, but the average age is about 24 months old. From 1998 to 2007, more than half of the incidents were caused by caregivers who forgot a child in the vehicle.

Hotcartemperature A car can heat up quickly even when it's relatively mild outside. On a summer day, temperatures inside the vehicle can climb more than 40 degrees in just an hour. The SFSU study points out that heatstroke occurs when a person's body temperature exceeds 104 degrees F. At just a few degrees more, 107 degrees F, cells are damaged and internal organs shut down, which can result in death. Children are particularly vulnerable, as their bodies are not as efficient as adults' bodies at managing temperatures. As a result, kids warm up much more rapidly.

Tips to help prevent these deadly accidents:

  • Never leave a child or pet unattended in a vehicle.
  • Check the car to make sure that all occupants leave the vehicle or are carried out when unloading. If you lock the door with a key, rather than with a remote, it would force that one last look in the car before leaving it.
  • Always lock your car and keep keys and remotes away from children.
  • Keep a stuffed animal in the passenger seat as a reminder of a child in the backseat.
  • Have a plan that your childcare provider will call you if your child does not show up.
  • For additional information on keeping your children  safe in and around motor vehicles, visit the Kids and Cars Web site.  Also, check out our car safety video above and learn more about hot cars. And do take extra care during the summer months to ensure that children and pets are not left behind.

    Premium gas can be a waste of money

    Premiumrecommended Many people use premium gasoline thinking that it’s better for engines than regular. That can be a costly misconception.

    Regular gas typically has an octane rating of 87, while premium is rated at 91 to 93. But octane grades don't represent "good, better, best"; they simply measure a fuel's resistance to pre-ignition (pinging or knocking), a condition in which gasoline burns uncontrollably in the engine’s combustion chambers, possibly leading to engine damage. The higher the octane rating, the more resistance it provides.

    Most engines are designed to run fine on regular gas. Using premium in them doesn’t improve performance; it only costs more money.

    Even many cars for which premium is recommended can use regular gas without a problem. That’s because most modern engines can detect the presence of pre-ignition (which usually occurs under high-load conditions) and automatically make adjustments to eliminate it. The tradeoff when that happens is a slight decrease in power and gas mileage, but most people probably won’t notice it.

    Generally, if your owner’s manual says "premium recommended," you can safely use regular gas.

    Some engines do require premium gas. They’re typically more powerful ones used in sports and luxury cars. Those engines use a higher compression ratio, which can make them run hotter and make them more vulnerable to pinging. The high octane fuel helps them resist the condition. So if the manual says "premium required," follow it.
