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.

Lexus IS sedan refreshed and restyled in Beijing

The current IS with its polarizing sheetmetal has been for sale since 2013, and Lexus has now updated the styling, turning it up a notch. The new IS has a mouth that is perhaps even more gaping than the outgoing model's front end. The intakes have been enlarged, making the front bumper more aggressive even on the IS200t base model. Along with a reshaped spindle grille, the headlights have been redesigned and now feature L-shaped daytime running lights. The checkmark-shaped "light guides" underneath them have also been made more pronounced. Lexus says they have reached for a design that would make the car look like it's in constant motion even when sitting still – perhaps a design cliche, but often attempted, and the character line on the sides has been enhanced for that reason. Did they succeed? You be the judge. Inside, the central information display has grown from 7 inches to 10.3, along with getting higher resolution. Otherwise, the interior remains much as it was. There are small touches here and there, including a redesigned gauge cluster, but mostly it's all about new color choices. On the engine front, the lineup continues to rely on three engine choices. The IS200t carries on as the downsized base four-cylinder option with a twin-scroll turbo charger and cycle-shifting Variable Valve Timing-intelligent Wide – still good for 241 horsepower. The IS300 gets a 255-horsepower V6 and the top-rung IS350 offers up 306 ponies from its 3.5-liter V6. Related Video: This content is hosted by a third party.

New Lexus IS Debuts at the 2016 Beijing Auto Show BEIJING (April 25, 2016) -- A daring new styling direction, exciting performance and innovative technology defined the completely new Lexus IS that was introduced in 2013. Since then, sales of the luxury brand's entry-level sedan have surpassed expectations, outselling the previous-generation model, which was very popular in its own right. At the Beijing Auto Show today, Lexus has taken the covers off the new IS, armed with a fresh new look and a number of important changes. Because the original styling of the current IS has proved so popular, Lexus has kept the essence of car's exterior appearance intact; however, the entire front fascia of the new model has undergone a transformation, highlighted by new headlamps, large air intakes in the front bumper and an evolution of Lexus' spindle grille.

Toyota reveals latest autonomous tech test bed

Toyota revealed its latest autonomous technology effort Friday, a sophisticated Lexus LS 600hL prototype that showcases its plans to advance in the emerging field. The Lexus is the first developed entirely by the company's in-house Toyota Research Institute and it will focus on the car's ability to learn and see behavior on the road. Toyota is showing the car at the Prius Challenge event at Sonoma Raceway. The Lexus uses Lidar, radar, and sensors, which potentially reduce reliance on mapping. The prototype advances Toyota's last concept vehicle shown at the Consumer Electronics Show in 2013. This one is said to be more flexible and it will focus on Toyota's two autonomous tech pillars, called Guardian and Chauffeur. Guardian is meant to improve safety features, while Chauffeur moves toward full autonomy. "We believe Guardian can probably be deployed sooner and more widely than Chauffeur, providing high-level driver-assist features capable of helping mitigate collisions and save lives, sooner rather than later," Toyota Research Institute Gill Pratt said in a statement.
