A new Toyota MR2? We want to believe

In the wake of a busy Geneva auto show, the rumor mill is churning, and the latest grist involves one of the most beloved Toyota sports cars of all time. EVO reports that Tetsuya Tada, the chief of the Scion FR-S/Toyota 86 project and a hard-liner about sportscar priorities (light and nimble, but with modest horsepower), wants a third vehicle for Toyota's nascent sporty lineup. Currently, we know there's a Supra-like vehicle in the works, being co-developed with BMW, and the 86 is sticking around. Tada said he'd like a third sportscar to compliment the two we know about, and that he wants it soon. A quick bit of history: Toyota's classic sporty lineup had three components. The most visible was the Supra, whose power and prestige grew as the car evolved from a cushy personal tourer to a high-horsepower, high-technology icon. The Celica was its Clark Kent, more mild mannered but also more accessible and affordable. The third was the MR2, a mid-engined go-kart that lasted for three distinct generations. Each had its charms, and all have their fans. When Tada says that he wants three sportscars in the lineup, we already know about the Supra successor, and the 86 is already filling the Celica's role, so the blank is easy to fill. It doesn't sound like Tada spoke the word "MR2" to EVO, or hinted that the car would be mid-engined, but Tada doesn't seem to say anything without purpose. Whatever the layout, this third car – if it comes to fruition – will probably play a role similar to the MR2 in relation to its stablemates. To translate: it'll likely be even lighter and more nimble, and probably less powerful, than the 86. The closest real-world analogue to the pure MR2 ideal is the Honda S660, a mid-engined Kei roadster that's on sale in Japan right now. It's light, small, and powered by a 0.66-liter inline-three. Toyota could decide to directly compete with the S660, borrow an engine from its small-car specialist subsidiary Daihatsu, and produce a mid-engined MR2. Another possibility, even simpler from Toyota's perspective, would be to adapt the existing Daihatsu Copen roadster. Sure, it's front-engine and front-wheel drive, but it's a small, light roadster. And even better, it sells abroad with a larger 1.3-liter engine. Restyle it slightly, perhaps to resemble the S-FR concept of a couple years ago, and it's an off-the-shelf solution. The S-FR itself is a third possibility.

400-hp Toyota Hybrid-R Concept gets second teaser

Toyota has released a second teaser of its Hybrid-R Concept, along with an estimation of the show car's power output. Using technology that's "similar to that used by Toyota Racing's TS030 Hybrid race car," the concept is expected to deliver over 400 horsepower.
The press release also mentions that the new concept is based on a current production model. While it's difficult to tell from the sole teaser image of the car's body, rumors are flying that it's related to the Yaris. If that's the case, though, it's difficult to know what to make of this concept. The teaser image is quite dark, but we played around with the exposure and came up with an image that reveals more details about the new concept. Take a look at the related gallery, below, to see the high-exposure image. We'll find out for certain what the Hybrid-R is in a few weeks at the Frankfurt Motor Show. Let us know what you think Toyota's newest concept is in the comments.

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.
