2018 Technology of the Year Award | We chat with Lexus about the LC 500h's hybrid system

Every year, Autoblog editors test dozens and dozens of the newest vehicles available, sometimes even before they're available. From those vehicles, we select the ones we think provide the most innovative technology in the industry. Then we pare the list down to the very best, test them again, and vote on our winner for Technology of the Year. This year, Lexus's multi-stage hybrid system — as tested in the LC 500h — came out ahead of the rest of the finalists. We chose the 2018 Detroit Auto Show to hand over the award to Lexus Group Vice President and General Manager Jeff Bracken. He was kind enough to sit down with Autoblog Senior Editor Alex Kierstein and Green Editor John Snyder at the Lexus stand to talk about the hybrid system, what it does, and what it means for the future of Lexus and Toyota. Check out the video above, and follow along for all our coverage from the 2018 North American International Auto Show in Detroit, where we are taking a look at all of the new cars and technology that we'll see in the near future. Perhaps the next winner of Autoblog's Technology of the Year award is sitting somewhere on the Detroit show floor.

Toyota recalling 20k 2014 and 2015 cars and CUVs with 3.5L engines

Toyota has announced a recall of roughly 20,000 vehicles covering the 2014 Avalon, Camry, Highlander (pictured) and Sienna, as well as the 2015 Lexus RX luxury crossover. The affected vehicles are all powered the 2GR-FE engine, which in layman's terms, is Toyota's well-regarded 3.5-liter V6.
According to Toyota's statement, a parts supplier might not have welded "the end cap on the right-hand fuel delivery pipe in the engine compartment" correctly, meaning fuel could leak. Leaking fuel, of course, increases the chance of an engine fire. That said, no fires, crashes or injuries have been reported due to the issue.
Owners will be notified to report to dealers, where techs will check the fuel delivery pipe and fit a replacement part as necessary.

The real reason automakers are giving away free hydrogen

Just like Hyundai did with its Tucson fuel cell, Toyota is offering free hydrogen fuel with the $57,500 Mirai H2 sedan. Toyota is being a bit vague about the details, saying simply that Mirai drivers will get, "complimentary hydrogen fuel for up to three years." Turns out, the reason that the hydrogen avant-garde will not be paying anything at the pump isn't because the automakers want to give them a boost or because the OEMs are kind. Instead, it's simply impossible to accurately charge people for hydrogen right now. It's simply impossible to accurately charge people for hydrogen right now. At an in-depth hydrogen seminar this week as part of the Mirai preview, three representatives from various hydrogen organizations revealed that the current hydrogen stations (most of which are in California) are not set up to accurately measure the hydrogen that is dispensed. Without this little bit of information, you can't charge customers for the fuel they use. Toyota is well aware of this, and Toyota Motor Sales' national manager of environmental, safety and quality communications, John Hanson, said that, "There are no set standards, so there is no way to charge people for anything." Alberto Ayala, the deputy executive officer for the California Air Resources Board, said CARB is in the middle of developing a way to sell a given amount of hydrogen, "which up to this point doesn't exist. If you think about it, it's a real simple yet real practical challenge. If you're going to pay for X amount of hydrogen, you're actually getting that amount of hydrogen." Ayala said it's not a difficult technical problem to measure the hydrogen as it goes into the car, but "we just have not done it. We are at a point where we are solving multiple remaining questions [with hydrogen infrastructure], and that just happens to be one of them." The National Institute of Standards and Technology says that there has been a discussion to change the current tolerance of two percent up to 10 or 20 percent, but that new technology should be able to measure accurately to within one percent. Air Liquide is working with Toyota to launch the Mirai in the US and Air Liquide CEO Ole Hofelmann told AutoblogGreen that being able to charge customers will be key to the technology's success. "We need to make sure we accurately measure the gas," he said.
