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 GX and LX future may be in doubt

With the debut of an all-new RX, Lexus is in a position for continued strong sales in the luxury SUV arena. The fourth-generation RX has grown, making room for the new NX model beneath it. But further up the ladder, things could change for the GX and LX. In an interview with Autoblog at the 2015 New York Auto Show, Lexus executive vice president Mark Templin gave some hints at the future of his brand's SUV lineup. "With NX and RX, we have a really good one-two punch in the crossover segments, and we think we can cover most of the markets with that," he said. As for the larger, three-row GX and LX models, which are built on a traditional ladder-frame chassis, things aren't so clear. Templin noted the the success of both models all over the world – the LX is the best-selling Lexus in Saudi Arabia. The same is true for sales here, he said: "We do very well with those products in the United States – GX has been a great product for us in the US for the last couple of years since its initial introduction. But the future of those vehicles longer term is in doubt because of regulations that are being driven by governments all over the world." Don't start stockpiling LX 570s in anticipation of shortages just yet. Templin didn't give any specifics; he just notes that tightening fuel economy and emissions regulations could affect product planning. In our analysis, if and when GX rides off into the sunset, Lexus still needs a midsize, three-row SUV to fill that gap. The most likely candidate for that is some variation on the RX. Whether or not that's the case, don't expect a BMW-like proliferation of body styles from Toyota's luxury division. "It creates problems. It creates complexity, that's hard for every step of the process," Templin said, nothing that too many models stresses the design department, manufacturing, and even dealers inventory selection. As for the bottom end of the lineup, Templin wouldn't comment on a compact SUV below the NX, saying "I think there are more potential options for us in the future, but we're not trying to grow the number of models we have in our lineup. It's not really what our core business is about." For now, Lexus and Templin are focused on launching the RX, which accounts for three of every 10 Lexus models ever sold. The 2016 model, available in RX 350 and RX 450h hybrid versions, goes on sale by the end of the year. Related Video:

Lexus previews LF-LC GT Vision Gran Turismo

Hot on the heels of the Alpine Vision Gran Turismo, the next in line to showcase its concept for GT6 is Lexus. Dubbed the LF-LC GT Vision Gran Turismo, the design is apparently based on that of the Lexus LF-LC concept that debuted at the 2012 Detroit Auto Show in red, reappeared in blue at the Australian Motor Show and is tipped to reach production as the LC 500. The virtual reality concept appears to encompass many of the same design cues, but in racing guise – not unlike the treatment Lexus applied to the RC F GT3 concept last year and with a similar white paintjob. More than that we couldn't tell you, but Polyphony Digital – the game studio responsible for the Gran Turismo franchise – says the official unveiling will follow soon.
