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.

Lexus LC 500 stands apart from the go-fast sport luxury crowd

We at Autoblog, by and large, love the LC 500. For its concept-car looks, derived almost verbatim from the 2012 LF-LC concept. And for the charming V8, which growls and burbles appropriately but doesn't subscribe to the faux-backfire trend. Our Editor-in-Chief, Greg Migliore, perfectly summarized the LC 500's appeal when he drove it recently: "Evening walkers cast curious glances. A guy in an old pickup almost sideswiped me as he gawked while taking the corner fast. It's a celebrity car. It also sounds good; the 5.0-liter V8 growls and rumbles. Style and muscle. An excellent execution." I just spent a week in it, my first encounter with the car, and it made me think most about how it's positioned in the Lexus lineup. Notably, it's not positioned as the performance extreme. This is refreshing, because not every car needs to attempt a Nurburgring time. If you want to hunt road-course records in this day and age, it takes massive power and massive traction. We're getting to the point, perhaps well beyond it, where that is doing the stopwatch more favors than the driver. Part of this is decades of marketing putting the sportiest variant of a particular vehicle above the most luxurious in the pecking order of regular vehicles, which doesn't make a ton of sense if you think about it. In the 1960s, the ultimate Mercedes-Benz was the 600 Grosser limousine, which was built like a Rolex bank vault. It had a huge engine, but the point was to move the massive thing around, not for the sheer pleasure of it. Ironically, the Grosser's engine made its way later into the 300 SEL 6.3, turning a large and luxurious sedan into a surprisingly capable bruiser, and then into the Rote Sau race car. Arguably, this was an impetus for the sort of sporty arms race I'm decrying. (Now, when you talk about supercars, or ultimate luxury cars like a Bentley or Maybach, this distinction makes less sense. But let's limit our discussion to vehicles the well-heeled average consumer could actually purchase — things at the upper end of the ranges of normal car manufacturers.) This takes us to the Lexus LC 500. Unlike Mercedes, whose Mercedes-AMG cars are on top of the regular car pecking order, Audi's RS line, BMW's M Division, and Porsche's various Turbos, the LC 500 is simply a large, powerful car. It's comfortable, it looks interesting, and it has more than enough grunt to get out of its own way. There are Sport and Performance options packages, but there's no LC F or F-Line trim available.

The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.
