Why Toyota's fuel cell play is one big green gamble

Imagine going to the ballet on Saturday evening for an 8 pm performance. The orchestra begins warming up shortly before the show, but it turns out the star performer isn't ready at the appointed time. The orchestra keeps playing, doing its best to keep the audience engaged and, most importantly, in the building. It keeps this up until the star finally shows and is ready to dance ... which turns out to be ten years later. That's a Samuel Beckett play. It's also how many observers, analysts, alt-fuel fans and alt-fuel intenders feel about the arrival of hydrogen fuel cell vehicles (FCVs) – the few of them who are still in the building, that is. Toyota's hydrogen development timeline rivals that of the US space program. In fact, within the halls of Toyota alone, research on FCVs has been going on for nearly 22 years, meaning that one company's development timeline for FCVs rivals that of the US space program – it was 1945 when Werner von Braun's team began re-assembling Germany's World War II V2 rockets and figuring out how to launch them into space and it wasn't until 1969 when a man set landing gear down on that sunlit lunar quarry. The development of the atom bomb only took half as long, and that's if we go all the way back to when Leo Szilard patented the mere idea of it, in 1934. Carmakers didn't give up on hydrogen in spite of the public having given up on carmakers ever making something of it, so there was a good chance that hydrogen criers announcing the mass-market adoption of periodic chart element number two one would eventually be right. Now is that time. And Toyota, not alone in researching FCVs but arguably having done the most to keep FCVs in the news, isn't even going to be first to market. That honor will go to Hyundai, surprising just about everyone at the LA Auto Show with news of a hydrogen fuel cell Tucson going on sale in the spring. The other bit of thunder stolen: while Toyota's talking about trying to get the price of its offering down to something between $50,000 and $100,000, Hyundai is pitching its date with the future at a lease price of $499 per month ($250 more than the lease price of a conventional Tucson), free hydrogen and maintenance, and availability at Enterprise Rent-A-Car if you just want to try it out. We've seen and driven Toyota's offering and we all know its success doesn't depend on cross-shopping, showroom dealing and lease sweeteners.

Toyota recalls 1.37 million more vehicles for Takata airbags

Toyota is expanding its passenger-side Takata airbag inflator recall campaign by an additional 1.37 million vehicles in the United States. The models covered under this broadened recall are the 2003-2007 Corolla, Matrix, and Lexus SC430; the 2005-2006 Tundra; and the 2005-2007 Sequoia. In total, Toyota says that this expansion brings the number of its vehicles covered under the Takata inflator recall in the US to 2.915 million. For these latest models, owners will be notified by mail soon. The move is similar to a recent decision by Honda to broaden its recall list. As with millions of other vehicles covered under these recalls, it's possible for exposure to moisture to cause the inflator to ignite too quickly in an airbag deployment. This can cause shrapnel to be sprayed at occupants. At least seven deaths have been potentially linked to these ruptures worldwide. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALL TORRANCE, Calif., June 16, 2015 – Toyota Motor Sales, USA, Inc. today announced that it is expanding its recalls involving Takata front passenger airbag inflators. Based on recent information from Takata and the National Highway Traffic Safety Administration (NHTSA), Toyota will recall approximately 1,365,000 additional 2003-2007 Corolla and Corolla Matrix; 2005-2006 Tundra; 2005-2007 Sequoia; 2003-2007 Lexus SC430 vehicles. This brings the total number of Toyota and Lexus vehicles covered by Takata recalls in the U.S. to approximately 2,915,000. In the involved vehicles, the front passenger airbag inflators could potentially be susceptible to rupture when deployed and seriously injure vehicle occupants. "Toyota's focus remains on the safety and security of our customers, and we will continue to respond promptly to new developments so we can resolve issues for them as quickly, conveniently and safely as possible," said Dino Triantafyllos, chief quality officer, Toyota Motor North America. Multiple investigations into the root cause of the potential for inflator rupture are taking place, including by Orbital ATK, an independent engineering firm commissioned by an industry-wide joint testing initiative comprised of the ten automotive manufacturers conducting Takata-related recalls. All known owners of the affected Toyota / Lexus vehicles will be notified by first class mail to return their vehicles to a Toyota / Lexus dealer. The dealer will replace the airbag inflator with a newly manufactured one.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
