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.

Next Toyota Prius may get optional all-wheel drive

We've been hearing rumors about the next generation of the Toyota Prius for the last couple of years on a pretty regular basis. From the expectation of lithium-ion battery packs with more capacity for electric-only miles to wireless charging and more emotional styling, there's been no shortage of talking points for the car that's expected to see its first light of day at the very end of 2015 (we hope). But one thing we've yet to hear about, until now that is, is all-wheel drive. According to a report from Automotive News, Koei Saga, senior managing officer in charge of powertrain development of the Prius, said in an interview last week, "I think we will possibly do [all-wheel drive]" for the car's next generation. There isn't any further indication on how the AWD system would work, but we'd put our money on something similar, at least in principle, to the E-Four system that just debuted on the 2015 Lexus NX 300h, which uses an electric motor mounted at the rear to power the car's back wheels when the front wheels lose traction. The AN report also repeats a rumor we've heard before – that Toyota may offer two different battery pack options in its next Prius, one using lithium-ion chemistry and one using the nickel metal hydride technology that the Prius has featured from its very beginning. While the automaker has yet to talk efficiency, it's natural to expect more capacity for EV driving from newer lithium-based technology over that of nickel-based packs to go along with what we'd also expect would be a somewhat higher price. We're sure you're just as curious about the next Prius as much as we are, and so we'll leave you with these words, again from Saga: "The batteries will be renewed. Everything will be revised. And I think we will come up with a fuel economy that will surprise everyone."

2014 Toyota Corolla debuts with more power, interior space

Depending on who you ask, the best-selling car in the world is either the Ford Focus or Toyota Corolla. Not surprisingly, Toyota claims it's the Corolla. Either way, we're talking around a million individual units per year, and over 40 million over the car's lifetime on the market, so the redesign of Toyota's compact sedan is big-time news for the Japanese automaker that it needs to get right.
The Toyota Corolla was last redesigned way back in 2008, meaning the 2014 model is a long-overdue update to the C-segment sedan. Its age shows when compared to newer rivals like the Honda Civic, Chevy Cruze, Hyundai Elantra and the aforementioned Ford Focus when comparing technology features, fuel mileage and interior roominess. In an effort to solve those demerits, Toyota has added nearly four inches to the 2014 Corolla's wheelbase and will offer a new continuously variable transmission with seven simulated gear ratios.
Engine choices consist of two available 1.8-liter four-cylinder units, one with 132 horsepower and 128 pound-feet of torque, and another more efficient version that uses Toyota's new Valvematic technology to offer 140 horses and 126 lb-ft of torque. Eco and Sport modes will be selectable by the driver.
