8 things you should know about the Lexus LC 500h powertrain

Lexus unveiled the LC 500h today in The Netherlands, and I got to take a look inside its new hybrid system. On one hand it seems like a box of magic – it combines two seemingly incompatible transmission types into one package. But that's also the ingenious simplicity of the thing. We don't have all of the details on how it all works yet, but here's a rundown of the high points.Efficient business in front, low-key party in the back. What makes it all work is the mullet of transmissions. For the new hybrid transmission, Lexus used the Toyota Hybrid Synergy Drive/Lexus Hybrid System – which consists of an e-CVT with a planetary gearset and two electric motors (one for charging the battery, the other for motivation and regen) – and grafted a conventional four-speed automatic onto the back. The two units actually coexist in one package, with the e-CVT making things efficient and the automatic expanding the capabilities. So at the low end, the system can deliver more torque, and the engine can also run at lower rpm on the highway. It's all thanks to those fixed gear ratios, and it's surprisingly simple.Except it's not that simple. This is where the virtual gear ratios come in. Like current Lexus hybrids, the system has ratios it can call up with the e-CVT. In this case, there are six virtual ratios to complement the four real physical ratios, for a total of 10 "gears" at the transmission's disposal. (Not coincidentally, the V8 LC 500 coupe has a 10-speed automatic.) One of the four fixed gears is always engaged when the car is moving, so the 10 ratios come about from combinations of what the e-CVT in front and the automatic in the back are doing. In other words, all 10 ratios are variations on the four fixed gear ratios, which means that all 10 gears could be considered virtual.It won't use all the gears all the time. In Eco mode, the car will start off on electric power and skip the first couple of "gears." When it's set to Sport or Sport +, the engine will be engaged from a stop and the transmission will select the lowest ratio. The sportier modes will also ignore the top couple of gear ratios.It can drive faster with the engine off. In a Lexus GS 450h with the Lexus Hybrid System, for example, at speeds above 62 mph or so the engine has to start up. This is because something needs to take up some slack from the battery-charging motor-generator or else it will start spinning too quickly.

Toyota aims to build autonomous car around 2020 [w/videos]

The race is on to get increasingly sophisticated forms of autonomous driving technology on the road, and brands like Tesla are bringing these solutions to some drivers now. But as one of the world's largest automakers, it's no surprise to see Toyota competing in the field, as well. By 2020, the company thinks a person could be largely unnecessary for freeway trips. With a suite of tech called the Highway Teammate, a modified Lexus GS is already showing what's possible. Using a combination of millimeter wave radar, LIDAR, and cameras, the GS gets a full view of the road, and software processes all of the info to make decisions. The result is a ride on the freeway without human interaction. The system can merge, change lanes, make passes, take curves, and maintain a safe distance from other vehicles. Accurate map data is a necessity to make this work, so the system currently only being tested on Tokyo's Shuto Expressway. While Highway Teammate might not be the best name, it accurately communicates the way Toyota thinks of the tech. The company is making big investments in artificial intelligence to assist drivers, not completely replace them. You can see the system in action in the video below, and the second clip's gravely serious narrator explains the company's idea of having a fully connected road someday.

New Toyota Test Vehicle Paves the Way for Commercialization of Automated Highway Driving Technologies Toyota City, Japan, October 6, 2015-Toyota has been testing a new automated driving test vehicle called Highway Teammate, with the aim of launching related products by around 2020. In addition to demonstrating the capabilities of next-generation safety technologies, the vehicle represents Toyota's view of the evolving driver-car relationship in the age of artificial intelligence. Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out. Toyota refers to this approach as the Mobility Teammate Concept, and Highway Teammate represents an important first effort to give form to this concept.

Toyota's future fuel cell vehicle lineup revealed?

Being an Olympic sponsor from 2017 through 2024 puts Toyota in the international limelight, and the company is preparing a fleet of efficient, cutting-edge vehicles just in time for the Tokyo games in 2020. At least eight new models could be on the way, according to Automotive News citing Best Car from Japan. Three of those might make use of the hydrogen fuel-cell powertrain developed for the Mirai. While many of these fuel cells are going into Japan-only vehicles, one of them could come here. Reiterating earlier rumors, Automotive News reports a hydrogen-powered Lexus LS is set for 2018. It could be even lighter than the current hybrid model, too. A similar version of the Toyota Crown would launch there in 2019 and possibly an FCEV Estima minivan, too. Beyond fuel cells, Toyota also intends to put the JPN Taxi Concept from the 2013 Tokyo Motor Show into production in time for the games, according to Automotive News. For 2017, the brand's flagship Century is also expected to adopt a hybrid V8 to replace the current V12, as well. Plus, many of its Japanese-market vans are also due for updates. All of this is certainly a massive undertaking to be ready in time, but Tokyo want to use the games as a chance to show the city as an innovative, international destination. Automotive News predicts Toyota could supply thousands of vehicles to haul all of the athletes and dignitaries around. In addition, the Japanese government wants 6,000 fuel cell vehicles on the road and 35 refueling stations up an running for the games. Related Video:
