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 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 wants improved crash scores with midcycle facelifts

The performances of some Toyotas in the Insurance Institute for Highway Safety's (IIHS) regimen of crash tests leave something to be desired. Consider the small overlap frontal crash test: only six Toyota, Lexus and Scion vehicles have undergone the new test, yet all but one of them received a poor rating. Osama Nagata, CEO of Toyota Motor Engineering & Manufacturing North America Inc., says midcycle vehicle updates are in the works to address the safety issues brought to light by the IIHS test, Automotive News reports. He confirmed that the RAV4 is getting safety updates following its crash test performance last month, but he didn't name any other models.
All three Toyotas that were tested - 2013 RAV4, 2012-2013 Prius V, 2012-2013 Camry - received poor ratings. The 2007-2012 Lexus ES 350 and 2006-2013 IS 250/350 also received poor ratings. The only other Toyota Motor Corp. vehicle to score better than poor is the 2014 Scion TC. It received an acceptable rating in the small overlap frontal crash test and is the only recent vehicle in Toyota's line-up to get the IIHS Top Safety Pick+ rating.
The small overlap front crash test measures the safety of a car when its front left corner is strikes an object during an accident, bypassing traditional crumple zones, which deform in a way to protect passengers. In 2009, automakers were alerted to the forthcoming addition of the test, which was first implemented last year, IIHS spokesman Russ Rader says. They responded with differing intensity, he says, pointing out that Subaru and Honda started incorporating design changes early on so their cars would perform well in the tests.
