The Toyota Camry has been the best-selling car in America for nearly 15 years, its reputation for reliability keeping it on top even when the carmaker was hurt by major safety recalls.
But its lead has shrunk dramatically. Feeling the pressure, Toyota unveiled the 2012 Camry on Tuesday, its first redesign of the sedan in five years. While Toyota hopes to create buzz by lowering the Camry's price, improving its fuel economy and adding new features, it may not be enough to keep the Camry No. 1 in the increasingly competitive market for midsize sedans.
"The Camry is not a slam-dunk by itself anymore," says Jesse Toprak, vice president of industry trends and insights for car pricing site TrueCar.com.
Toyota showed off the new Camry on the Web and at events in California and elsewhere. It has given the car a sharper, more pointed hood, a quieter and roomier interior and more trunk space. It's also offering Entune, a system that lets drivers access internet services like Pandora from their mobile phones using voice commands or an in-dash touch screen.
But critics say the styling is bland compared with edgier rivals like Nissan, Hyundai and Kia, and that Toyota saved money by using cheaper interior materials.
"There's nothing fundamentally wrong with it, but is that good enough nowadays? No, it's not," Toprak says.
The new Camry is due to arrive at dealerships in early October. A basic version will cost just under $22,000 and get 35 mpg on the highway.
Toyota has sold more than 15 million Camrys worldwide since it introduced the car in 1983 to compete with the Honda Accord. It quickly became a big seller in the U.S. because of its reputation for reliability and good gas mileage. The Camry outsold the Ford Taurus in 1997 and has been the best-selling car in America every year except for 2001, when it was eclipsed by the Accord. Even Toyota's embarrassing series of safety recalls last year and earthquake-related shortages this spring didn't knock it down from No.1.
Toyota's U.S. sales chief Bob Carter says the company aims to keep things that way, in part by being aggressive on price.
A basic Camry will now start at $21,955, which is $710 more than the current model. But most other versions will cost less than current ones. The top-of-the-line version, for example, will start at $24,725, or $2,000 less. The hybrid Camry, which starts at $25,900, is $1,150 less.
At that starting price, the Camry will cost a little more than some of its competitors, such as the $19,200 Kia Optima. But Carter says the car includes a lot for the price, including the most air bags — 10 — in its class.
Toyota has also tweaked the Camry's engines to get better fuel economy. The four-cylinder engine, which makes up the bulk of Camry's sales, will get 35 miles per gallon on the highway, up from 32 in the 2011 Camry. The hybrid version will get a combined 41 miles per gallon in city and highway driving. Those numbers make the Camry one of the most fuel efficient sedans among its competitors.
But it remains to be seen whether Toyota can draw back buyers who started shopping other brands after Toyota was hit by huge recalls that involved sticky accelerators and floor mats that trapped gas pedals. Customers also ran into shortages this summer after Japan's earthquake disrupted production.
Toyota's lead has been slipping the last four years. In the first seven months of 2007, the company sold more than 282,000 Camrys, trouncing what was then its closest competitor, the Honda Accord, by more than 62,000. Camry sales were more than double the Nissan Altima's, and more than three times those of the Ford Fusion, Chevrolet Malibu and Hyundai Sonata.
Now the Camry's top five rivals are within striking distance. The Altima was only 21,000 behind through July, and the Fusion just 23,000 back.
Toprak and others say the Hyundai Sonata is most worrying to Toyota. Its fuel economy equals the 2012 Camry but it has more horsepower, and its styling is more daring. Its starting price is also $2,300 lower than the Camry's. Camry sales were down 8 percent through July, while the Sonata's were up 21 percent.
Aaron Bragman, an analyst with IHS Automotive, thinks the new Camry will probably win over many of the 6.8 million people already driving the car in the U.S. But he's unimpressed by the vehicle's cheaper looking hard plastic surfaces and knobs, and he thinks some shoppers will be, too.
"I don't think it's going to bring anybody new to the brand," he says.
But Camry has proven its staying power before. And while analysts also criticized the cheaper materials used on the new Volkswagen Jetta sedan, Jetta sales were up 75 percent through July.
Toyota Motor Corp. President Akio Toyoda visited the Georgetown, Ky., plant where the Camry is made Tuesday, underscoring the car's importance. Toyoda said he personally tested the new car until he was satisfied that it outperforms its competition.
"This car has become a symbol of Toyota's success," he said. "This is an opportunity to show the world again what Toyota is all about."

Practical Invisibility Cloaks: Printing technique yields large sheets of light-bending materials
Technology Review
Aug 23, 2011
Results: Researchers have developed a stamp-based printing method for generating large sheets of metamaterials, a new class of materials that interact with light in ways not seen in nature. They've used it to make sheets of a metamaterial that measure nearly nine centimeters per side, orders of magnitude larger than was previously possible. Tests showed that this material, which bends light backward, actually has better optical properties than materials made using more complex methods.
Why it matters: Small-scale experiments suggest that metamaterials might be used to make invisibility cloaks, superhigh-resolution microscopes, and other exotic optical devices. But so far researchers have been unable to create such devices at a practical scale because metamaterials are difficult and time-consuming to make. Slow, precise methods such as electron-beam lithography have typically been used to carve intricate nanoscale patterns into the layers of metals and other components that make up these materials. The largest pieces previously produced were only a couple of hundred micrometers long.
Methods: The researchers started with the design for a metamaterial that others had produced a few years ago, using slower methods. They made a hard plastic stamp patterned with the grid stipulated by the design. Then they "inked" the stamp in an evaporation chamber by depositing several thin films: first a sacrificial layer, then layers of the metal and dielectric materials that make up the metamaterial. Finally, they set the stamp on a surface and chemically treated it to dissolve away the sacrificial layer, freeing the metamaterial from the stamp. The stamp was pulled away, leaving the metamaterial on the surface. Each stamp is reusable and inexpensive to make.
Next Steps: The researchers expect that by using more than one stamp, they will be able to make much larger metamaterial sheets. The method can also be adapted to work with other metamaterial designs, but the researchers hope other scientists will use it to make large amounts of this particular material for cloaking and other applications.
Transparent Batteries
Electrodes with features smaller than the eye can resolve could lead to see-through electrical devices

Proceedings of the National Academies of Sciences, published online July 25, 2011
Results: Researchers have made fully transparent batteries and used them to power a light-emitting diode. The prototypes can store as much energy as a nickel-cadmium battery of the same volume.
Why it matters: Transparent batteries are the last missing component needed to make transparent displays and other see-through electronic devices. Researchers have previously made transparent variations on other major classes of electronics, including transistors and the components used to control displays.
Methods: The researchers designed electrodes made from a mesh in which all the lines are on the order of 50 micrometers—smaller than is visible to the human eye, so the result appears transparent. To make the electrodes, they first used lithography to carve a silicon wafer into a mold with a raised grid pattern. Liquid PDMS, a clear, squishy polymer, was poured over the mold and peeled away once it solidified. Researchers then dropped a solution containing standard materials for lithium-ion electrodes onto the grid of narrow channels on the surface of the PDMS sheet. Capillary action pulled the materials into the sheet until all the channels were filled, creating the mesh. Finally, the researchers sandwiched a clear gel electrolyte between two electrodes and encased the entire system in a protective plastic wrapping.
Next Steps: The researchers want to improve energy storage by an order of magnitude—to about 200 watt-hours per liter—by reducing the thickness of the polymer substrate and deepening the trenches that hold the electrode materials.

Breakthrough in Ricardo Kinergy ‘second generation’ high-speed flywheel technology
Ricardo Press release
Aug 22, 2011
The subject of nine Ricardo patent families in application, Kinergy represents a step-change advance in mechanical energy storage technology. It is based on a high-speed carbon fibre flywheel operating within a hermetically sealed vacuum chamber at speeds of up to 60,000 rev/min. But unlike current devices in which energy is imported and exported via a drive shaft operating at flywheel speed, Kinergy transfers torque directly through its containment wall using a magnetic gearing and coupling system. This new breed of high-speed flywheel technology offers the prospect of enabling the unit to be sealed for life, thus avoiding the need for high-speed seals and a vacuum pump, and hence reducing costs and maintenance requirements. The consequent weight and space saving potential provides for a competitive packaging envelope, while the ability of the efficient magnetic coupling to incorporate a high gear ratio makes the input and export of torque significantly more manageable than would be the case in a more conventional direct driven high speed flywheel design.
This first Kinergy prototype has resulted from a fast-track engineering development process intended to deliver the unit that will be at the core of the Flybus high-speed flywheel mechanical hybrid powertrain demonstrator vehicle. Following precise balancing of the flywheel rotor during construction and assembly, the unit was installed on a specially constructed dynamometer for development testing. Successive tests have been carried out at increasing speeds and compared with the results of engineering simulations of performance and efficiency. A major thrust of that development has been the elimination of stray magnetic losses in the coupling, and breakthroughs have been made that are critical to the success of the technology.

Ford and Toyota Team on Hybrid System
Engineerblogger
August 22, 2011
You might think that automakers always have one another in the crosshairs. But it turns out there can be opportunities for collaboration, especially when it comes to advanced technology and bringing it to the public sooner and more affordably than one automaker could do alone. Case in point? Ford and Toyota, the two leading manufacturers of hybrid vehicles, have signed a Memorandum of Understanding with the intent to jointly develop a hybrid system for light trucks and SUVs.
The two will potentially bring the best of their independently developed hybrid powertrain technology and knowledge to a new co-developed hybrid system, which may be used in rear-wheel-drive light trucks. Ford and Toyota have been working separately on similar new rear-wheel-drive hybrid systems aimed at delivering higher fuel economy in light trucks and SUVs. When the two companies began discussing this potential collaboration, they discovered how quickly they were able to find common ground.
While the proposed rear-wheel-drive hybrid system may share significant common technology and components, Ford and Toyota will individually integrate the system into their own vehicles. Each company also will determine the calibration and performance dynamics characteristics of their respective light pickups and SUVs.
“This is the kind of collaborative effort that is required to address the big global challenges of energy independence and environmental sustainability,” said Ford President and CEO Alan Mulally.
In addition, as telematics plays an increasingly more important role in the in-car experience, both companies have also agreed to collaborate on standards and technologies needed to enable a safer, more secure and more convenient in-car experience for next-generation telematics systems. The telematics collaboration relates only to standards and technologies, and each company will continue to separately develop their own in-vehicle products and features.
“We have unique and very good solutions today with SYNC® and MyFord Touch™. Working together on in-vehicle standards can only enhance our customers’ experience with their vehicles,” said Derrick Kuzak, Ford Group Vice President, Global Product Development.
