How Toyota's Le Mans racer may make its next Prius even better

The supercapacitor technology in the Toyota TS040 "offers great possibility for production car use." – Amanda Rice, Toyota Pop-culture junkies familiar with 1980s touchstone movies will hear the word "capacitor" and think Back to the Future. But the concept of supercapacitors being used in upcoming production models is being pushed by Toyota, not DeLorean. And because of that push, the future might look a little brighter for the Prius. The Japanese automaker will likely apply electric-motor technology used in Toyota's 24 Hours of Le Mans entry – the TS040 – in future versions of the world's best-selling hybrid, Australian publication Drive.com.au says, citing an interview with Toyota Motor Sports' Yoshiaki Kinoshita. Specifically, the racecar uses supercapacitors because they're effective at storing energy created when the vehicle is under braking, only to quickly redistribute it on demand for rapid acceleration. Kinoshita said Toyota may apply this technology to the Prius within the next five years. While declining to comment on specifics, Toyota spokeswoman Amanda Rice tells AutoblogGreen that the Le Mans vehicle "represents an advanced vehicle laboratory for hybrid vehicle and component development. The supercapacitor technology used in this vehicle with its fast charge and discharge capability offers great possibility for production car use." In her email, Rice added that the next-generation Prius will have smaller electric motors with greater power density and thermal efficiency, so let's add that to what we know or think we know about the fourth-generation model. Toyota entered two vehicles in this year's Le Mans race, and one of them had secured the pole-position and was leading much of the race before calling it quits 15 hours in because of electrical issues. Audi ended up winning the race, marking its 13th victory in the history of the French endurance contest.

The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.

Toyota hits 10 million Camry models sold in US

This year marks 30 years of sales for the Toyota Camry in the US, and in that time, it has amassed more than 10 million sales. In its first year on the market, the Camry sold 52,651 units, but it has gone on to become the best-selling car in the US for the last 11 years.
Toyota says that "virtually all" current Camry models sold in the US are made here, and three-quarters of all Camry contents are domestically sourced. Scroll down for the official press release from Toyota, and be sure to check out our gallery of images showing every model year and bodystyle of the Camry since it first went on sale in 1983.
