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.

2015 Lexus NX offers bold design, compact luxury

Meet the all-new NX, Lexus' entry into the space occupied by the likes of the BMW X1 and Mercedes-Benz GLA. Based off the LF-NX Concept and sharing much of the design language seen on the polarizing IS sedan, the NX looks to be a rather sporty Lexus crossover.
The big news here is under the hood: the NX will be the first Lexus to use a turbocharged engine. That's right, a 2.0-liter, turbocharged four-cylinder can be found in both the NX 200t and NX 200t F Sport. There will also be an NX 300h, and if Lexus' nomenclature remains consistent, we already know all about that one. As of right now, there aren't a lot of details on either powertrain, although with the NX's Beijing debut still over a week away, here's hoping we know more soon.
As for that design... well, we're waiting to see it up close. The initial reaction from the Autoblog team has been mixed so far. Like the IS, there are plenty of sharp angles, while the front is dominated by the brand's spindle grille. Lexus' designers have refined the shape of the headlights, giving them a cleaner overall look than on the pioneering IS. In back, LED taillights come standard. According to Lexus, 17-inch wheels are the base rollers, while 18s are optional.

Toyota to suspend 18 assembly lines as production restarts post-quake

TOKYO - Japanese manufacturers began restarting production at plants in the country's quake-hit northeast, but Toyota Motor Corp said it plans to idle 18 assembly lines for a few days next week due to a shortage of parts from suppliers. It had suspended operations at three factories due to the quake and sees lost production of 20,000 units due to the stoppages. Toyota has already cut its global production target due to the ongoing chip shortage. The suspension will cut heavily into Toyota's domestic production. Impacted product lines include the Toyota RAV4, Land Cruiser, Harrier and Yaris and virtually every Lexus. Toyota did not say whether these shutdowns could extend to U.S.-based production lines, but the possibility exists if they receive parts from the same suppliers.  On one hand, the limited damage caused by the magnitude 7.4 temblor has highlighted Japan's success in building resilience against the frequent tremors that shake the archipelago. But the quake has sparked concerns of further disruptions to a pandemic-hit supply chain for precision components vital to electronics and autos production and in which Japanese manufacturers play a leading role. Murata Manufacturing Co Ltd, the top global supplier of ceramic capacitors used in smartphones and cars, said it restarted production on Friday at two stopped plants with the remaining two idled plants to restart next week. A fire that broke out at a factory which produces chip inductors caused some damage to equipment. Renesas Electronics Corp, which makes nearly a third of the microcontroller chips used in cars globally, said it has restarted production after stopping it at two factories with a partial stop at a third. All three factories, including the Naka factory where fire broke out last year, are expected to return to pre-quake capacity by Wednesday, Renesas said. Power has mostly been restored across the northeast, which suffered Japan's biggest earthquake 11 years ago. Areas of Tokyo lost power for nearly three hours after the latest quake, in which three people died and 183 were injured. The blackout has forced the disposal of some COVID-19 vaccines held in cool storage, the Yomiuri newspaper reported. Tech conglomerate Sony Group Corp is in the process of gradually restarting production at three factories in the quake-hit area, a spokesperson said.
