Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

Anti-EV, pro-hybrid ad from Lexus gets a whole lot wrong

Tell us if you're surprised that Toyota (through its Lexus brand) is putting out some questionable information about electric vehicles. While it's one thing for company executives to be anti-EV, it's quite another to put out obviously false information when you speak ill of plug-in vehicles, especially when you also sell them. The automaker offers the RAV4 EV and Prius Plug-In, albeit in limited numbers, First, let's look at what Lexus is saying. On the company's consumer site, in the hybrid section, there are a number of slick videos. In one ("Hybrid Overview"), Lexus makes it look like charging an EV takes four hours. That may be true in some situations, but the video shows an anonymous driver plugging a Nissan Leaf into something that looks like a AeroVironment DC fast charger, which takes around a half hour to charge. Granted, the site has a disclaimer that says, the "charge time represents the average time to charge from empty to full using typically available 240V commercial charging stations," but in everyday use, that's not something EV drivers often do. Charged EVs mentions two previous studies that show how most EV charging is done at home. Lexus knows all this, of course, but doesn't mention it. Lexus says that there are 20 states with an "established infrastructure" for hydrogen. Another video on the site, one that talks about future alternative powertrain technologies, says that there are 20 states with an "established infrastructure" for hydrogen and 37 with the same for electric vehicles. It also blatantly says that we need to consider all of the emissions from the fossil fuels used to make electricity (carbon monoxide, sulfur dioxide, etc.) but does not say anything about the fossil fuel emissions used to make hydrogen. You can see some screen grabs in the gallery or watch the video yourself. It's all blatantly one-sided, especially since the official numbers from the Department Of Energy say that there are Level 2 public EV chargers in literally every state except Alaska and only 11 public hydrogen stations in the US. Ten of them are in California, the other is in South Carolina. A Lexus spokesman told AutoblogGreen it will ask TeamOne, its ad agency, and the Lexus marketing department for clarification on where the data in the videos comes from. We will update this post when we hear back.

Jaguar solution to keyless start could save lives

UPDATED: An earlier version of this story indicated the Jaguar keyless start function was meant as a safety feature, when in fact, it is meant as a convenience one and will not work as described if automatic stop/start is not engaged. Today, The New York Times published an article about more than two dozen deaths related to drivers accidentally leaving their cars running, closing their garages and later succumbing to carbon monoxide that flooded their homes. The reason has been identified as "keyless start" features, or proximity entry and push-button start, where owners don't need to physically handle a key or fob to gain entry into the vehicle or start it. It is the latest, and deadliest, issue raised with this system after those related to security and simple inconvenience (for instance, leaving the car at a valet or car wash with the fob in your pocket). From my personal perspective, The New York Times had a rather harsh "evil carmakers" tone throughout the article. This is not a matter of a known faulty component, as with the GM ignition switch recall. This has as much to do with user error where people leave their car without pressing the "off" button and without noticing the engine is still running. About half of the cars in question are produced by Toyota and Lexus, brands that have offered keyless start longer than most. They are also brands with high rates of elderly owners, who seemingly made up a majority of reported deaths and injuries. One fire department in Florida even started a campaign alerting those in the area of the dangers of leaving your car running when it noticed a correlation between an increase in cars equipped with keyless start and calls related to carbon monoxide poisoning. I see several contributing issues at play, most of which go well beyond this particular issue. First is insufficient training of owners by dealers and/or owners not paying close enough attention during this training. Cars are complicated, but you should at least know how basic functions work. Second, woefully inadequate driver training in this country. Third, and with apologies to the AARP, insufficient testing of elderly drivers and/or insufficiently low standards for elderly drivers. If you don't know you have to shut the car off or cannot hear that an engine is running, perhaps you shouldn't be driving. Fourth, re-examining keyless start systems.
