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 RZ battery electric crossover teased

Lexus has dropped a teaser video glimpsing the brand's first fully electric vehicle to be sold in the U.S. Called the Lexus RZ, it features the angular styling we've come to expect from Toyota's luxury marque, but underneath the sheetmetal we're probably getting a foundation we've seen quite a bit of in recent weeks. That's because the Lexus RZ is a third version of the battery-electric crossover co-developed by Toyota and Subaru, recently unveiled as the confusingly named Toyota bZ4X (it always requires a double check of the alphanumeric sequence) and the much better named Subaru Solterra. All three are built on the e-TNGA platform that will underpin several EV models. However, the Lexus RZ signals a more significant departure from the bZ4X and Solterra, whose differences were quite limited. They looked almost indistinguishable, the only things setting them apart being a mild reshape of the front fasica and taillights, painted wheel arch cladding on the Toyota, and an option for a single-motor 2WD drivetrain on the bZ4X.

Right away, the lack of gray cladding around the wheel wells is apparent. There still appears to be some, but much slimmer than that of the bZ4X and Solterra. A strong character line flows from the leading edge of the front wheel arch to the rear door, where it's picked by another upturned character line leading into a blacked out C-pillar. Naturally, the front features a large Lexus spindle grille shape (there doesn't appear to be an actual open radiator intake, unnecessary for an EV) and unique headlights branded with "L" fishhook DRLs. The rear offers a much sleeker appearance as well, with slim taillights that don't droop downward into the bodywork. A solid light bar features the word "Lexus" printed across rather than the traditional L-in-a-circle logo. No details or interior images were shown, but we'd guess that the cabin is quite a bit nicer than the decent but run-of-the-mill cockpit of the bZ4X and Solterra. Lexus has stated it will not offer the single-motor option. However, its Direct4 all-wheel-drive system is a departure from Subaru's, and the Lexus is said to be capable of 402 horsepower and 442 pound-feet of torque. Those figures completely blow the bZ4X and Solterra out of the water.

Toyota Camry, Lexus RX to get aluminum parts

Ah, aluminum. The lightweight, strong material has long held a following within the premium ranks, but as Ford prepares to launch an aluminum F-150, the material is gaining acceptance among more mainstream automakers. Toyota is one such brand, with a new report indicating that the Japanese giant will add aluminum bits and bobs to some of its upcoming vehicles.
These won't be full, aluminum-intensive treatments like the F-150, however. Automotive News reports that an aluminum hood and liftgate will be coming to the 2016 Lexus RX, and following that, the Camry will get a bonnet built from Element 13 for model year 2018.
As AN points out, Toyota is no stranger to aluminum, using it in Japanese-built models like the Prius and Scion FR-S. The RX and Camry, though, will mark the first time the company's North American factories will use the material, and they'll do so on a significantly larger scale, owing to the higher volumes that the Camry and RX represent.
