Toyota unveils two new small displacement engines

Toyota introduced a pair of brand-new engines in Japan today, that it says will eventually spawn 14 different variants by 2015. Where these two engines stand out in today's world, is that neither mill boasts direct injection, and both are naturally aspirated.
The larger of the two is a 1.3-liter, while the smaller engine, a 1.0-liter, was developed in collaboration with Daihatsu. What makes these two unique is that they both use the Atkinson cycle. Now, we aren't going to bore you by explaining just what this is - there's Google for that. Suffice it to say, Atkinson engines are highly efficient, but that efficiency comes by sacrificing power. That's why they're so popular in hybrids, which can offset the power losses.
This focus on fuel efficiency extends throughout the new engines, which also benefit from tweaks like a cooled exhaust gas recirculation system and a trick intake port, while the 1.3 employs Toyota's iE variant of variable valve timing. Both engines can be fitted with stop-start tech. According to Toyota, when fitted with stop-start the 1.3 should provide around a 15-percent bump while the 1.0-liter will increase economy around 30 percent, when they arrive on the road.

Toyota's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

Toyota gives up more information on Frankfurt-bound Yaris Hybrid-R concept

Toyota has undeniably carved out a niche for itself as the industry's leader in hybrid propulsion. What started out with the original Prius in 1997 has, over the past sixteen years, ballooned to what Toyota reports as a global hybrid portfolio of 23 models. But few (if any of them) are particularly exciting.
That's where the Yaris Hybrid-R concept comes in. Set to be showcased along with the rest of Toyota's hybrid and fuel-cell lineup at the upcoming Frankfurt Motor Show next month, the concept starts with one of the Japanese auto giant's least exciting models and upgrades it to more enticing territory. Toyota Motorsport GmbH - the same Cologne, Germany-based division that operated the company's F1 team, currently runs its Le Mans program and gave us that bonkers 650-horsepower Lexus LS - has slotted in a version of Toyota's new 1.6-liter Global Race Engine and paired it with a couple of electric motors for hybrid propulsion and through-the-road all-wheel drive.
Like the TS030 Hybrid LMP1, the Yaris Hybrid-R concept uses a super capacitor (instead of a conventional battery) to store the regenerated brake energy and give it upwards of 400 horsepower. That's about all Toyota is revealing at this point, but this is the first time it has confirmed the project is based on a Yaris, of all things, and the confirmation comes with the solitary teaser rendering you see above. Check out the press release after the jump and watch this space for more as Frankfurt fast approaches.
