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.

What does a million-mile car really tell us?

A million miles. Nearly every car brand and motor oil company plays the million-mile marketing racket at some point. The typical recipe is to take a car that experienced a ton of low-stress highway miles, and make it a rolling testament to the long-term qualities of whatever reputation you're trying to prop up. Saab, Lincoln, Toyota, Honda, Ford, Chrysler. It's a tired game that I would normally just consider one of the pointless ranking exercises of our time. But the truth is, when it comes to a car's longevity, it's almost always the owner that makes the real difference, not the brand. Like a pitcher at a baseball game, the owner mostly determines the victories and the defeats for his car. Some specific models are the basement dwellers of our time – I'm looking at you, Chrysler car with the 2.7-liter engine! But a lot of cars and trucks hit right around the average that is a powertrain whose longevity is mainly determined by that person who turns the key and hopefully learns that patient art of long-term ownership. The best owners are the ones who deserve the attention. So with that in mind, let me introduce you to Matt Farah's Million Mile Lexus. This content is hosted by a third party.

This Lexus could be written off as another cynical marketing exercise in this business, performed by those who didn't do the real driving in the past and have no plans at all on doing the bulk of the driving in the future. Matt's actually doing a few things that are genuinely cool, though. Letting other auto journalists and enthusiasts drive it along the way and giving Regular Car Reviews a crack at it. Focusing on the rare virtues of the first-generation Lexus, which, to be frank, can out-diesel a diesel. There is a great story to be had with this car. This isn't a car that was "going to the junkyard" and magically given the kiss of life. That story is far more vast than a guy who bought a high-mileage car in great overall condition. This isn't a car that was "going to the junkyard" and magically given the kiss of life so that it can endure the ages. This Lexus, like all other high-mileage models worthy of our love, has been given one hell of a good maintenance regimen by the prior owners. It was taken care of and primarily maintained at the dealership, where it probably received the best parts and service, thanks in enormous part to owners who were willing to pay that exorbitantly high bill.

Google shares more details on self-driving car accidents

Google has pledged to release monthly reports on the status of its self-driving car program, and says these updates will include information on accidents involving the vehicles. But the company won't release the actual accident reports, a sore point for activists who recently have clamored for the company to be more transparent in the way it tests this promising technology on public roads. "Google is dribbling out bits of information in the hope to silence legitimate calls for full transparency," said John Simpson, privacy director for Consumer Watchdog, a nonprofit that has asked Google to release reports from the 12 accidents the company says it has been involved in over the past six years. "They are testing on public roads, and the public has a right to know exactly what happened when something goes wrong." Under California law, the accident reports are not considered public records. Google has attributed all accidents to human error, and says drivers of the other cars involved caused 11 of the 12 accidents. In eight of those, the Google cars were rear-ended, and the autonomous vehicles were sideswiped in two other crashes. One of the accidents occurred at an intersection when a human driver failed to yield at a stop sign, and in one incident, a Google driver accidentally rear-ended another car while manually driving. Google had previously provided those details. The first monthly report installment sheds new light on which types of self-driving vehicles were involved, directions of travel, locations, and whether the cars were operating in autonomous or manual mode. Update: Google says this information comes directly from the OL 316 forms used to report accidents involving autonomous cars in California, though it has "edited the summaries lightly to protect other drivers' information." But Google still will not release the original OL 316 forms, nor the "traffic collision report" forms used in California to report accidents. Another company that has been involved in a single self-driving car accident, Delphi Automotive, has released this information, which verified its car was not at fault. Regarding Google, Simpson said, "We now know a few more details of what happened. The problem is that it's Google's version and they want us to take their word for it." The Google self-report adds information that goes beyond accidents, with further details on the company's overall program.
