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, Lexus recall 460,000 vehicles for stability control issue

Toyota and its luxury subsidiary, Lexus, are recalling 460,000 electrified models produced for the 2020-2022 model years to address an issue that can cause the vehicles' stability control systems not to activate on startup. If you drive a new Toyota or Lexus and it has at least one electric motor in it (or it's the new LX 600), there's a better-than-even chance you'll be hearing from your dealer in the coming months. The good news for owners is that the issue is one of compliance, rather than something which may immediately endanger a vehicle occupant.  "A software error can cause the Vehicle Stability Control system (VSC) not to default to ON the next time the car is started under certain circumstances. This can result in a noncompliance with applicable regulations in the U.S," Toyota said in its announcement. "For all involved vehicles, Toyota and Lexus dealers will update the software of the Skid Control ECU free of charge to customers." Included in the campaign are the 2020-2022 Toyota Venza, Mirai, RAV4 Hybrid, RAV4 Prime, Sienna Hybrid, and Highlander Hybrid. On the Lexus side, it hits the LS500h, LX600, NX350h and NX450h+. Notably absent here are the Tundra-based trucks with the new iForce Max hybrid, though Toyota may have addressed the issue in those models before they went on sale. On the other side of the coin, the LX 600 — a purely ICE model for the time being — managed to stumble into the defect pool.  Toyota says owners should receive notices before the end of June.

Lexus LF-C2 Concept shows polarizing looks are here to stay

Well, that's one question answered. When Lexus released the first teaser for its LF-C2 Concept, we figured it'd be one of two things - either it'd be a convertible based on the LF-LC Concept car or it'd be a thinly veiled concept version of the RC Convertible. Turns out, it's kind of both.
The LF-LC styling straddles the wilder, concepty looks of the LF-LC and the still wild, but more grounded, looks of the RC. That doesn't mean it's not a polarizing piece of design, with Lexus styling trademarks like the dominating spindle grille and separate LED running lights. Lexus' knife-edge cuts and folds in the bodywork have been toned down relative to past concepts, but the overall look here, particularly in the rear fenders, is rather busy.
"The LF-C2 concept shows what's in store for our brand's future design direction," Lexus boss Jeff Bracken said. "This concept shows consumers around the world Lexus' devotion to emotional designs as well as our passion for an exceptional driving experience."
