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 and Lexus recalling 235,000 hybrid CUVs and sedans over separate issues

When it rains, it pours. Toyota has announced a pair of separate but voluntary North America recalls covering approximately 235,000 vehicles built between 2006 and 2011. The larger of the two recalls targets Toyota's hybridized crossovers, the Lexus RX400h and Toyota Highlander Hybrid. 133,000 units, including 2006-2010 Highlander and 2006-2008 RX crossovers are covered in the campaign. The other recall affects 102,000 IS350 sedans, IS350C convertibles and GS350 sedans built between 2006 and 2011.
With the CUVs, the faults in the parallel circuits of the transistors can cause heat damage in the inverter assembly, triggering an abundance of warning lamps and sending the vehicle into limp mode. The Lexus sedans are being recalled due to loose bolts on the variable valve timing controller. Detected by unusual underhood sounds on startup, the issue can cause the engine to stop while driving. The inverter issue is also triggering similar recalls in Japan and Europe.
At the moment, it's unclear if any of these issues have caused any crashes or injuries. Toyota says it plans to notify owners of the recall via snail mail. Additional information for owners can be found on the recall sites for Toyota and Lexus or by calling Toyota's customer service line, at 1-800-331-4331.

2022 Lexus IS 500 F Sport Performance brings back the V8

The 2022 Lexus IS 500 F Sport Performance revives the dormant IS F formula, bringing V8 power back to the compact luxury Japanese sport sedan for the first time since 2014 and confirming rumors of a new series of V8-powered performance (small p) cars from Lexus. Very little surprises us these days, especially in the luxury segment, but if you'd told us a month ago that we'd be confirming a V8-powered Lexus IS and a new, all-four-cylinder lineup for the Mercedes-Benz C-Class in the same week, we'd have called you crazy. Parent company Toyota's presence in Texas may have rubbed off on Lexus, though, because after a years-long hiatus, the V8-powered IS sedan returns. That's right. A V8. In a brand-new compact sport sedan. In 2021.  The new sport sedan will pack a 472-horsepower, 5.0-liter V8 with 395 pound-feet of torque, making it the spiritual successor to the discontinued Lexus IS F. For those keeping track at home, yes, that's the same V8 Lexus has utilized elsewhere in recent years. It currently powers the RC F coupe and, until last year, was also found under the hood of the larger GS F sedan. Like the BMW M3 it matches for power, the Lexus will come standard with rear-wheel drive and a limited-slip differential, making it a true performance machine. Power will go to the rear end by way of the same eight-speed automatic Lexus uses elsewhere as well. Sorry, folks, there's no stick, but hey, the IS F didn't have one either, so let's not get too picky. The original IS F also offered just 416 horsepower and 371 lb.-ft. of torque, so remember, this is all upside here. The original also launched without the LSD, if you'll remember; that came later.  2022 Lexus IS 500 F Sport Performance View 26 Photos The other significant edge the IS 500 F Sport Performance will have over its two-generations-removed predecessor will be the benefit of almost a decade's worth of interior development. While the IS platform was not significantly overhauled for the 2021 "re-imagining" (as Lexus puts it; we prefer the term "remodel"), the interior was, and the IS 500 F Sport Performance will benefit from all of the base sedan's upgrades, including a thoroughly overhauled infotainment system, which is night-and-day better than what was offered previously.
