Details about next-gen Toyota Prius emerge

The Toyota Prius is undeniably the king of the hybrid market in the United States, with a 39.4 percent market share in 2013. With the next-generation Prius likely to go on sale in 2015, Toyota is trying to build an even more efficient hybrid to keep its control of the market.
Keeping cost down will be one of the major concerns of the new Prius. The next generation will ride on the new, modular Toyota New Global Architecture platform. The lighter underpinnings will improve efficiency and will reduce production costs by allowing for more shared components among vehicles. Toyota will not reveal how many vehicles will use the new platform. But even with the cheaper platform, price will remain a concern. Toyota is still deciding whether all versions of the next Prius will use lithium-ion batteries or whether some models will stick with the heavier nickel-metal hydride batteries to keep cost down.
Of course, the reason most people buy the Prius is because of its great fuel efficiency. Toyota will aim for at least an 8 percent improvement in fuel economy in the next Prius, which would increase it to 58 miles per gallon city and 52 mpg highway.

NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.

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.
