Lexus NX rolls on wheels made of ice

To create this rolling ice sculpture, Lexus teamed up with London-based Hamilton Ice Sculptors, which fitted the compact luxury crossover with wheels and tires crafted from ice. The sub-zero craftsmen then deep-froze the entire vehicle, stored it at -22 degrees Fahrenheit, and drove it around London – pleasantly surprised to find that it started on the first try. As far as publicity stunts go, the finished product looks even cooler than the cardboard IS that Lexus had crafted a few months ago or the biometric glow-in-the-dark RC F from this past summer. The project took three months of research, design, and testing to carry out. The wheels replicate the alloys on the NX with millimetric precision, right down to the tread pattern, and each one took a team of four craftsmen 36 hours of work to complete. Of course, blocks of ice would have a hard time supporting the weight of the vehicle – especially while in motion – so the frozen wheels were reinforced with clear acrylic discs. And to make it all glow, they were also fitted with in-wheel LED lighting. This isn't the first time we've seen ice sculptors apply their skills to automobiles, following the frozen Canadian Tire pickup, Toyota Land Cruiser, Nissan Cube, and Saab Aero-X we've seen in recently years. But this one is at least as cool, in one sense or another. Scope out the results in the video above, and the process that went into their creation in the making-of video below.

LEXUS NX RIDES ON THE WORLD'S COOLEST WHEELS – CRAFTED IN SOLID ICE The concept of driving on ice has taken on a whole new meaning for Lexus, which has crafted the world's first set of working wheels and tyres made from frozen water. Brussels, Belgium - True to its mission of "creating amazing" and inspired by the craftsmanship that goes into every vehicle it makes, Lexus commissioned a team of ice sculpture specialists to explore how ice could be used in place of conventional alloy metal and rubber. After three months' research, design and testing, the finished wheels were fitted to a Lexus NX for the ultimate ice drive. The car itself was deep-frozen, stored for five days at -30°C (it started first time) before being driven off down a London road. The addition of in-wheel LED lighting added an extra dramatic dimension to the cutting-edge contemporary styling of the NX.

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.
