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.

With a top speed of 187 mph Bentyaga will be the fastest production SUV on the road when it hits the market. Eventually, Bentley intends to launch a seven-seat version, a higher performance Speed model, and more efficient diesel and hybrid variants of its new luxury SUV. Dawn is the new four seater convertible from Rolls-Royce. While the car looks to the past for its name it boasts lots of modern tech including Rolls-Royce's Zed F eight-speed automatic transmission for imperceptible gear changes and a silently operating, six layer, canvas top. The launch of Toyota's latest Prius marks the fourth generation of the popular hybrid. Prius has gone from a niche product to one of the industry's most important vehicles. Toyota hopes its new Prius will redefine the category it helped to pioneer. We're expecting fuel economy to increase by 10 percent and this is the most tech laden Prius ever. Those are the highlights from the week that was. Be sure to check out my full recap this Saturday. Plus, some insight on the new Cadillac XT5. For Autoblog, I'm Greg Migliore.

Toyota Yaris Hybrid-R is road-going version of brand's racing technology [w/video]

Did you know that the Yaris is Toyota's best-selling vehicle in Europe? That may help explain to us Americans why the car that's lowest on the company's totem poll here in the US got turned into an all-wheel-drive hybrid track monster for the 2013 Frankfurt Monster Show.
Called the Toyota Yaris Hybrid-R, this three-door pocket rocket isn't just a hybrid making a lot of horsepower - it incorporates technology from Toyota's TS030 Hybrid racecar that competes in the FIA World Endurance Championship series, including the 24 Hours of Le Mans. The Yaris Hybrid-R packs a 300-horsepower, turbocharged, 1.6-liter four-cylinder engine under its hood, which should be enough for most speed freaks, but Toyota pairs it with two 60-hp electric motors at each rear wheel (the same ones used in the production Yaris Hybrid that's sold in Europe). That makes total system output an insane-for-this-size 420 hybrid horsies.
But that's not all, as the Yaris Hybrid-R forgoes the traditional battery pack below the rear seats in favor of a supercapacitor, which can both hold more energy and has a much faster power charge/discharge speed than traditional batteries. Paired with the supercapacitor is a third 60-hp electric motor/generator positioned between the engine and six-speed sequential transmission. Its job is to feed the super capacitor energy during deceleration and direct its power to the rear electric motors when more grip and oomph is needed.
