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.

Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Recharge Wrap-up: Minnesota first to require biodiesel, maglev in Israel, Toyota FCV in Aspen

A new Minnesota law that requires biodiesel blends goes into effect in just a few days, says KELO. Diesel drivers in Minnesota will be pumping soybeans into their tank beginning July 1. Every year, diesel will be sold as a B10 blend (ten percent biofuel) from April through August, and will scale back to a cold-hardy B5 blend from September through March. The biofuel largely comes from soybean crops grown within Minnesota, and the biodiesel industry pumps more than $900 million into the state economy every year. According to the National Biodiesel Board, using the B10 and B5 blends will reduce greenhouse gas emissions by 1,342,000,000 pounds every year. Minnesota is the first state to require diesel to be sold as a biofuel blend. In Japan, Isuzu Motors and Japanese biotech venture Euglena are teaming up to create biodiesel using algae, according to Bloomberg Businessweek. The goal is to create a new type of fuel that doesn't need to be mixed with light oil to be used in engines. "As long as we use light oil for diesel engines, emissions of carbon dioxide are inevitable," says Isuzu president Susumu Hosoi. Euglena has also been using algae to develop jet fuel with airline operator ANA Holdings. Isuzu and Euglena hope to have the new biodiesel developed by 2018. Aerial maglev transportation is coming to the campus of a defense contractor in Tel Aviv, Israel, Wired reports. The SkyTran personal rapid transit system uses small pods on an elevated magnetic track to move people from place to place. The pilot program will see SkyTran come to the corporate campus of Israel Aerospace Industries as soon as next year. The pods are hailed by phone, and carry passengers along the magnetic rail system at speeds of up to 44 miles per hour. The passive magnetic system levitates the pod attachment a centimeter above the rails, while a burst of electricity propels the pod forward. If the test at the campus goes well, SkyTran could spread to Tel Aviv at large, moving up to 12,000 people per track per hour with top speeds of 150 mph. The pre-production prototype of the Toyota FCV will make its North American debut at the 2014 Aspen Ideas Festival on Friday, June 27. The hydrogen car's finished exterior was revealed in Japan on Wednesday along with its nearly $70,000 price tag. It will go on sale in Japan by April of next year, and will come to Europe and California in the summer of 2015.
