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.

Is this the fourth-gen Toyota Prius? [w/video]

A new video has appeared on Prius Chat of a camouflaged hatchback that just might be the next Toyota Prius. There's nothing here that concretely proves what we're looking at is the fourth-generation model of the world's best-selling hybrid, but upon first glace, the Prius guess makes sense. In an ironic twist, the car was caught because it needed gas. Prius Chat user Savior1974 says that the car was spotted on a drive between Las Vegas and California in Baker, CA. Savior1974 wrote, "As we are leaving we see a car dressed as it were being road tested. Upon further inspection it looks like it might be a Prius. I took a quick video as I drove by but it's not the best quality." The launch of the next-gen Prius has been delayed because of more work that was needed to make the car more efficient and to improve the styling. Work on getting the Prius to work well with the new Toyota New Global Architecture platform also needed more time. Last summer, we heard rumors that the Prius' new design would be finalized in November 2014. There are a few points to keep in mind that might point to this being something other than the next Prius. First, the all-black, electrical-tape-style camo is not the normal wrap that the Toyota Technical Center uses for testing (compare with these early shots of the Prius C and these other fourth-gen Prius spy shots). Second, the Baker grade between Las Vegas and California (where the video was shot) is full of vehicles being tested by any number of automakers. Nonetheless, the lines of this car do look like a Prius, so we leave you with a gallery of stills from the video and, of course, the video itself, above.

2019 Toyota Avalon vs. full-size sedans: How they compare on paper

Full-size sedans aren't exactly in great demand at the moment, and at least one of the vehicles in this comparison has been rumored to be on the endangered species list. Yet, we've just had our first drive in the 2019 Toyota Avalon, and if anything has a chance of rejuvenating the segment a bit, it's an all-new version of what has long been the segment's benchmark. To see how the new Avalon compares, we've put together the below spreadsheet featuring the Avalon's primary apples-to-apples rivals, the Buick LaCrosse and Chevy Impala. We also included the Nissan Maxima, which is comparable in price, sales and non-luxury badge, and which offers the sort of increased driver engagement promised by the new Avalon XSE and Touring trim levels. We also included the outgoing Avalon for reference as well as that car's luxury cousin, the Lexus ES, which can definitely be cross-shopped with the luxuriously trimmed Avalon Limited. You can use our Compare Cars tool to create your own comparison, such as one featuring the rear-wheel-drive Chrysler 300, Dodge Charger or even Kia Stinger. Alright, enough chit chat. On to the spreadsheet. Performance and fuel economy The GM sedans may come standard with four cylinders, including a mild hybrid system in the LaCrosse, but puh-lease. The V6 is the name of the game in this segment, with outputs now surpassing the 300-horsepower mark. The LaCrosse is the horsepower and torque champ, though it also weighs a bit more than the new 2019 Avalon, so acceleration is likely to be comparable. The Impala weighs a lot more and has only a six-speed automatic, so despite having a wee bit more power, one should expect it to be pokier (not a good sign for a car rumored to be on the chopping block). One would expect the Maxima's 300 hp and lowest curb weight to result in the quickest acceleration, but then it's also strapped to a CVT, which despite being better than ever, is still a CVT. Things get worse for Chevy when you consider the Impala's base four-cylinder gets the same 25 mpg combined as the Avalon's V6 — once again a segment best. Now, should you really prioritize fuel economy, the 2019 Toyota Avalon Hybrid really stands out with a 43 mpg rating (or 44 with the base XLE trim) that bests the outgoing Avalon Hybrid. Honestly, after driving this new Hybrid, it actually seems like it would be the best bet for most buyers. There's sufficient power, and it only costs $1,000 more than the comparable V6 version.
