Toyota engineer warns automous cars could increase fuel use, urban sprawl

An increasing number of people are starting to consider the potential downsides of a transition to autonomous cars. The FBI is already looking at them for the potential ill effects on law enforcement, and a scientist for Toyota is raising the possibility that driverless vehicles could actually be detrimental to the environment over the long term.
Ken Laberteaux, who studies future transportation for Toyota, thinks that autonomous cars could lead to more pollution, not less, says Bloomberg. However, Laberteaux's theory isn't so much based purely on science as it is considering behavioral and historical trends. "US history shows that anytime you make driving easier, there seems to be this inexhaustible desire to live further from things," said Laberteaux during a presentation at the Automated Vehicles Symposium in San Francisco, CA, cited by Bloomberg.
Laberteaux's belief is that if commuters can make their drives easier, then they will be more willing to live farther away from the cities where they work. The end result would be more urban sprawl and increased pollution from the longer travel times.

Consumer Reports says Toyota, Ford, Honda and Chevy are big winners in brand perception survey

According to Consumer Reports, the automotive brands that stand out in the minds of car buyers are, in order: Toyota, Ford, Honda and Chevrolet. This news comes after the magazine polled its readers, asking them to take into account vehicle quality, safety, performance, value, fuel economy, design/style, and technology/innovation - which are the factors that car shoppers are most influenced by.
It's important to note that this award is only about perception. In other words, it's perceived quality, not actual quality. "Often, perception can be a trailing indicator, reflecting years of good or bad performance in a category, and it can also be influenced by headlines in the media," said Jeff Bartlett, Consumer Reports deputy automotive editor.
The brand that made the biggest jump in perception amongst Consumer Reports readers is Tesla, which posted an impressive 47-point gain to finish in fifth place. Subaru is also notable for finishing in the top 10, despite being one of the smaller manufacturers doing business in the US.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further.
