Does the Toyota Prius still matter?

Toyota remains incredibly proud of its green halo car, the Prius. On the company website, it calls the gas-electric car, "The hybrid that started it all." Chances are, if someone tells you to think of a hybrid car today, your first thought is going to be the Prius. Now a cultural icon, the Prius changed a lot of attitudes about what an efficient car is able to achieve. But the car is aging, despite numerous refreshes and model tweaks over the years, and sales dropped 11.5 percent last year. It's taken Toyota 25 years of ups and downs to get the Prius to where it is today, and we started wondering if that's too long for the car to remain viable in an era of 40+ mile-per-gallon non-hybrid cars and a plethora of plug-in competitors for the green car crown (we're not the only ones). Plus, Toyota is rapidly shifting its green focus away from the Prius and towards the hydrogen-powered Mirai fuel cell car. But if you ask Toyota representatives if the Prius is still a vital car in 2015 – and we did – you'll find that there's still a lot of love for the car that went before. For example, Geri Yoza is a Toyota national manager who spent years traveling all across the US teaching people about the Prius. The veteran of countless customer education sessions told AutoblogGreen that it took a long time for the Prius to "cross the technology chasm," and that it wasn't until about a decade after launch that the car became a common sight outside of the initial popularity hotspots. "It takes a while for people to become confident in the technology, to understand that it's been proven," she said. Now that the hybrid is ensconced in the public mind, it's time for the next step. "I think the Prius, the whole idea 'to go before,' was to go before the Mirai." Part of that precursor status is due to the fact that a lot of the Prius' powertrain technology has made the jump to the Mirai. When we asked Bob Carter, Toyota's senior vice president of automotive operations, if the Prius still matters, he had a clear answer: "My goodness, yes." "We've been selling hybrids for 25 years," he said, "but when you go back, we had said that the Prius and hybrid technology were a bridge to the future and we were very clear that it's going to be a very long bridge. Essentially, and I'm not an engineer, the Mirai takes the technology from the Prius and takes the ICE engine out and puts a fuel cell stack in.

How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Toyota Recalls 1.9 Million Prius Hybrids

TOKYO (AP) - Toyota is recalling 1.9 million hybrid Prius cars globally for a software glitch that could cause the vehicle to stall. Toyota Motor Corp. said Wednesday that 997,000 Prius cars in Japan, some 713,000 in North America, another 130,000 in Europe and the rest in other regions are being recalled for a problem in the software to control the hybrid system. No accidents or injuries have been reported related to the problem. The software could cause transistors to become damaged, causing warnings lights to go off, driving power to be reduced or the car to stop. The recalled vehicles were manufactured between March 2009 and February 2014. The Japanese automaker suffered massive recalls starting in 2009, affecting more than 14 million vehicles for problems including floor mats, gas pedals and brakes. Affected vehicles include: 2010-2014 Prius vehicles, 2012 Toyota RAV4, 2012-2013 Toyota Tacoma and 2012-2013 Lexus RX 350 vehicles sold in the United States.
