Algae slime makes good “Fuel” for moviegoers

For an alternative perspective on the future of the automobile, it may help to look at an alternative film. “Fuel” by Josh Tickle is a thought-provoking documentary that examines America’s addiction to oil and what we can do about it.
 
Tickle does a good job of keeping the serious subject rather upbeat and hopeful, as he travels the world in his so-called Veggie Van, fueled by used vegetable oil. The film is engaging and friendly, cajoling audiences into sympathy with its message, not browbeating them.
 
Tickle is a fan of biodiesel, and a lot of the movie is focused on that fuel. Biodiesel is a promising alternative that until recently had problems only with scalability. It worked terrifically for the few consumers who made the commitment to use it, but it looked difficult to supply enough to fuel more than a million or so of America’s roughly 240 million cars. (Read “Diesel vs. biodiesel vs. vegetable oil.”)
 
“Fuel” also documents the growth of the algae biofuel movement, which promises to create economies of scale that biofuels have not had before. (We’ll look into this fuel movement and share our own findings later.)
 
Statistics on alternative fuels are notoriously squishy. Different studies show different advantages. But as a student of these studies, Tickle’s numbers are within the range of those cited by neutral sources, unlike those of some other documentaries on the automotive industry.
 
That’s not to say the movie doesn’t occasionally paint a rosy picture. As with other documentaries, its problems are more of omission, rather than commission. Framing the discussion around biofuels results in a myopic exclusion of any discussion of fuel cells, batteries, or the micro-level economics fundamental to most American families.
 
For example, after it spends a significant amount of time interviewing officials and citizens of some European countries moving off of oil, and noting how they may pay less for biodiesel than for petroleum-based fuel, it fails to mention that consumers in the United States almost always pay more.
 
And “Fuel” misses the point that the government is now heavily subsidizing the development and distribution of electric cars and plug-in hybrids to wean the U.S. off of oil. And while it touches on the future of wind and solar power, it never mentions the fact that these alternatives also need advanced batteries that can piggy-back off the development of new batteries for cars.
 
One amazing statistic in the film compares the cost of funding wars in Iraq and Afghanistan (to protect American access to oil, the film posits) with the cost of providing enough solar panels to meet the electricity needs of every household in the United States. Based on our check of government and solar industry figures, the cost would be about $350 billion, or about three years of averaged war funding. (Admittedly, the issue is more complex than pure dollars, but it is an interesting bit of trivia, nonetheless.)
 
Accepting the biodiesel emphasis for what it is, leaves an informative and engaging documentary. It raises interesting questions worth considering, and it’s worth seeing even for those who consider themselves pretty well informed on alternative fuel issues.

Audi, MIT develops dashboard robot AIDA as a mobile assistant

Lots of people talk to their cars—even if few admit it. So far those conversations are pretty one-sided, with the exception being a voice-recognition navigation system. That may one day change. Exploring the potential for future man-machine interaction, Audi has teamed with the Massachusetts Institute of Technology to develop an interactive robot that not only talks back, but can also learn your driving habits, help you navigate, and even warn you of danger approaching.
 
Nicknamed AIDA, for Affective Intelligent Driving Agent, this robot  sprouts up from the top of the dashboard, smiles, frowns, and tilts its “head” to convey emotion. It is like having your own in-car Wall-E. So if the MMI isn’t enough of a distraction, here comes AIDA.
 
Researchers at MIT say that within a week of driving AIDA will learn where you live, where you work, and the route you take in between. If that route is congested, it will suggest alternate routes. If the car is low on gas, it will suggest you travel through the cheapest gas station along the route. Within a month, it will learn where you like to shop, and can route you by the grocery store.
 
AIDA can be more than a frivolous companion, though. Using forward radar, electronic stability control and other sensors, AIDA can warn of possible collisions and advise you on how to avoid them. The system’s virtual eyes merge into a cyclops – a single circle of dots surrounding a red warning triangle. And by choosing the shortest routes and avoiding traffic, it can save gas.
 
Having your car look after you, however, strikes some as “nannying.” Further, depending on how well AIDA can keep secrets, there may be a way for others to know where you’ve driven, including a spouse or car thief.
 
Should mobile assistant technology advance, those old jokes about the car knowing its own way on familiar routes may become all too true. However, AIDA is unlikely to appear on production cars any time soon.
 
Would you want AIDA for a copilot? Share your thoughts in the comments.

Video: Taylor Swift SNL spoof mocks bad parent drivers

Teens deservedly get a lot of flack for distracted driving, especially talking on the cell phone and texting, but they aren’t the only ones who engage in bad driving behavior. In a recent Saturday Night Live episode, teen musician Taylor Swift (yes, the same Taylor Swift who swept the Country Music Association Awards Wednesday night) did a very funny sketch on the show about bad parent drivers. In the skit, Taylor plays a 15-year-old who campaigns against her parent’s bad driving habits with such topics as “Driving While Arguing with the GPS” and “Driving While Trying to Get Something Out of Your Purse,” plus a number of other real life, relatable parent/teen discussions. Check out the clip of the show.


We all know about the dangers of distracted driving and it not only affects teenagers, but all drivers. This is a real danger, even though the skit is thoroughly funny and entertaining, the subject is no joke. 

Distracted driving is a national issue that has jumped onto the government stage at the recent Distracted Driving Summit and more states are instituting driving while texting bans. With the addition of Rhode Island this week, there are now 19 states that have enacted bans and another five states will have their laws in place in the coming weeks. Parents are stretched to the limit now more than ever and often multitask in the car to get everything done. However, it is especially important to teach kids good driving habits, remembering that they learn by example.

While the SNL skit brings back flashbacks of the awkward and embarrassing teen years, it also highlights, some driving offenses many of us are guilty of on a daily basis. Let’s all have a chuckle, then rededicate ourselves to not making the same mistakes.

Chrysler’s business plan: The Fiat platforms

Chrysler-fiat-platformsFiat-based platforms will have a big influence on Chrysler’s small and midsized products, based on a multi-hour presentation given today to the industry, media, and anyone else who wanted to monitor. Chrysler currently has no small cars, but by 2014, they will have three models based on two Fiat platforms, one being the 500.
 
The biggest platform shift is in the larger segments. According to Chrysler, this now has eight different platforms: 
Click the links above for model overview pages featuring ratings and road tests, available to online subscribers.

By 2014, nine different products will stem from just two platforms – and one of those platforms is exclusive to the Wrangler. The Wrangler’s product line and reach will be extended, with major product modifications in both 2010 and 2011. Wranglers have an iconic image, they sell well, and their low-tech design is likely provides a handsome profit. While they perform well off-road, Wrangler’s don’t perform well on the road or in CR’s Ratings; the Wrangler is currently our lowest-scoring vehicle.

Wrangler aside, this means that eight products, covering vital products like midsized sedans and small and crossover SUVs, will all come from one Fiat Group platform. (Given that Dodge said that the Viper will be redesigned, perhaps this slide shown here from the presentation is short a platform for that low-volume street rocket.) While the decision isn’t finalized, the midsized Dakota may move to a unibody platform, like the Honda Ridgeline.
 
Moving to larger products, things remain pretty much status quo. Those platforms will continue to be sourced from Chrysler, with a large sedan platform (300, Charger, Challenger), a minivan platform, and another midsized SUV platform (Grand Cherokee, Durango). The Ram brand keeps its own platform—no surprise.
 
The first domestic-badged Fiat-based product is expected in 2012, a compact sedan sold by Dodge. That year will also bring Ram-badged large and small commercial vans, filling the big hole left from the Mercedes/Freightliner-shared Sprinter.

How to stop a runaway car: Don’t pump the brakes

Despite a massive recall by Toyota of 3.8 million vehicles to address sudden runaway acceleration, National Highway Traffic Safety Administration (NHTSA) is still investigating the exact cause of this problem. They are concerned that the accelerator pedal getting stuck by the floor mat – the purpose of the recall - is not the exclusive cause, according to the New York Times.

Whatever the cause of unintended acceleration, the best defense is to know how to safely regain control of the car should it happen to you. In a previous post, we wrote that putting a car in Neutral might save your life. Our latest tests show that pumping the brakes at full throttle can make a bad problem even worse, as demonstrated this video from ABC News. (See the report "Owners of Toyota cars in rebellion over series of accidents caused by sudden acceleration" at ABCNews.com.) 

A NHTSA report released this week points out that some drivers can “react by applying the brake pedal multiple times, depleting the braking system’s (vacuum based) power assist.
 
Testing theory at the track

We decided to find out just how quickly you could lose power brakes with a stuck throttle. Using our test track and several test vehicles, we accelerated to 60 mph and hit the brakes with the accelerator still floored. Once the brakes were applied, the vehicles began fighting us. The transmissions downshifted trying to maintain speed.
 
Instead of holding the brakes, we tried pumping them. This test confirmed that pumping the brakes is a really bad strategy. Power brakes rely on engine vacuum to provide additional brake pressure. At full throttle, the engine doesn’t generate any vacuum. So as soon as we removed and reapplied pressure to the brake pedal, the power assist disappeared and stopping the car became hopeless. “There was no way I could push hard enough on the brakes to slow the car down when the engine was fighting me,” said Sr. Automotive Engineer Jake Fisher.
 
Bottom line
The best strategy to stop a runaway car is to press and hold the brakes and shift into neutral. Modern cars have rev limiters, which will protect the engine from over-revving. Even if your car doesn’t, don’t worry about your engine’s life—worry about your own.

Video: Diesel comparison - BMW, Mercedes-Benz, Volkswagen

For buyers looking for a fuel efficient car, diesels provide an alternative to hybrids. Popular in Europe for years, more diesels are making their way to the U.S. market.

Modern diesels escape many of the liabilities of earlier designs. They are quieter, burn cleaner, and have much improved acceleration. Fuel economy is considerably improved over gasoline-powered versions.

But buying a diesel usually means paying more up front. Finding a diesel pump isn't quite as easy as locating gasoline, and diesel fuel prices recently have fluctuated widely. Except for Volkswagen, diesel vehicle availability is also limited to high-price luxury brands.

In this video, we take a look at four diesels—Mercedes-Benz GL320 Bluetec, BMW 335d, BMW X5, and the Volkswagen Jetta TDI—and their pros and cons.

2009 Annual Auto Reliability Survey: Domestics vs. the imports

Asian vehicles continue to lead in car reliability, but a number of domestic and European automakers are showing improvements. Of the 48 models with top reliability scores, 36 are Asian—Toyota accounts for 18; Honda, eight; Nissan, four; and Hyundai/Kia and Subaru, three each. The rest come from Ford with eight; Mercedes-Benz, one; Volkswagen, two; and Volvo, one.

European brands continue to improve in reliability with a significant rebound from Mercedes-Benz and improvements from Volkswagen and Audi. Most Volvo and Porsche models have also done well in our survey.

Ford leads the domestics with about 90 percent of models scoring average or better in our survey. Overall 20 of the 48 GM models have average reliability, but only the Chevrolet Malibu V6 has above average reliability in our survey. Last year, we couldn’t recommend any Chrysler product due to low test scores and poor reliability, but this year the 4WD Dodge Ram did well in our tests and has average reliability. However, more than one-third of Chrysler products are much worse than average in reliability.

The graphs below show the percentage of models that rate above average, average, and below average for Asian, European, and American brands.

Video: How to choose the best tires

At a glance, all tires look alike. They are black, round, and ringed with tread patterns. But there are significant differences in how they perform and how they wear. Since tires are the only part of the car that touches the road, it is crucial that you make a smart, informed decision about what tire is right for you. And we can help.

As demonstrated in this tire buying video, Consumer Reports runs a comprehensive, year-round tire testing program to ensure it can deliver the advice and ratings you need. To evaluate all aspects of a tire, we put it through a number of objective and subjective tests in the most comprehensive tire-test program of any American magazine or Web site.

We test braking and lateral grip on dry and wet surfaces, handling in our emergency-avoidance maneuver, and hydroplaning resistance, which measures how well a tire maintains contact with the road in standing water. We evaluate how easily a tire can accelerate on moderately packed snow and we rent a local skating rink to test braking on ice. Outside labs evaluate tread life and rolling resistance which is a function fuel efficiency . To ensure consistency, we buy each tire model in the same size and mount them on the same test cars.

Check out our video to see the details on how we conduct these tests. Then see our car, SUV and truck, and winter tire ratings (available to subscribers) to find the models that score well in the areas that matter most to you. All site visitors can access our free buying advice for tips on getting started, types of tires we test, features that are important in making a tire purchase, and general tire care. Also, be sure to check out our TireTalk forum to interact with our tire engineers and other drivers.

Video: Cell-phone navigation apps vs traditional navigators

Navigational aid is increasingly available on cell phones, giving consumers a choice between purchasing software for their smart phone or buying a dedicated portable navigation device (PND). The Consumer Reports GPS testing team has been conducting tests to compare these two scenarios, pitting cell phones against PNDs. So far, PNDs have a clear advantage in accuracy and ease of use, though software-based solutions are rapidly improving. In fact, with iPhone applications we have been quite frankly challenged to keep up with the perpetual updates, which can outpace our rigorous test procedures.
 
We have tested eight iPhone apps thus far, and we have found that they do a decent job of mimicking the abilities found in traditional devices. In fact, GPS-makers Navigon and TomTom have entered the fray with apps that feel quite familiar to our staff.
 
Generally, the initial apps were a bit rough around the edges, lacking iPhone integration and some common, or at least recommended, navigation features. This is improving over time, though in our experience, accuracy remains an inherent challenge for the iPhone.
 
This video highlights the trade offs in choosing a phone-based solution, though we encourage you to dig deeper in our articles and reviews to determine which is best for you.
