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.

Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota recalls 370k Sienna minivans, 10.5k Lexus GS models over separate issues

The year of the recall continues, but this time it isn't from General Motors. Toyota is announcing two, separate recalls affecting a pair of its models.
First, Toyota is recalling 370,000 Sienna minivans from the 2004 to 2011 model years that are registered or originally sold in cold-weather states. The problem is that the spare tire carrier assembly cable can be splashed by water contaminated with road salt and cause corrosion. There is a splashguard in place to prevent this, but it sometimes gets lost in "normal usage," according to the company. If the cable does break, then "the spare tire may separate from the vehicle."
This is actually the second repair for this problem for some of these vehicles. In 2010, Toyota issued a recall on 600,000 Siennas from the 1998 to 2010 model years. At the time, it installed a new splashguard and sprayed the area with an anti-rust chemical. However, according to Toyota spokesperson John Hanson speaking to Autoblog, the campaign worked for the 1998 to 2003 models but wasn't sufficient for the newer ones. For the latest recall, the vehicles are getting the entire cable replaced with a stainless steel unit and a new splashguard.
