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: Let's Play

Lexus opted to air a second ad during the 2015 Super Bowl, this time featuring its 2015 RC350 coupe. There is much drifting, both with a remote-controlled RC (yes, an RC RC, which is kind of the whole joke) and the full-sized, 306-horsepower coupe. It's a fairly creative spot and entertaining spot, so give it a look. You can check out our impressions of the new RC in our comprehensive First Drive.

Lexus RZ electric SUV will be shown (with a yoke) on 4/20

Lexus will reveal its production RZ electric SUV on April 20, the company announced Tuesday, steering well clear of April Fool's Day with a teaser package that would be right at home in Elon Musk's Twitter feed. And yes, there's a yoke. If it weren't for the fact that we already knew about the Lexus RZ, coupled with confirmation from Toyota that the bZ4X's yoke is the real deal, we'd be highly suspicious of this early-April announcement from a traditionally conservative manufacturer. Welcome to 2022, when none of that really seems to matter anymore.  We already suspected that the RZ was based on Toyota's bZ4X, so the indication of an available yoke is not that surprising, really.  In the Toyota, it's paired to a variable-ratio, steer-by-wire system. Toyota says it also improves steering feel and ensures road and tire vibrations don't make their way to the driver. The latter seems obvious since there's no physical connection between the wheel and road, but whether that makes for an "improvement" in steering feel is not something with which we're inclined to automatically agree.  Lexus offered no further info apart from the reveal date and time (6 a.m. EDT April 20) and these new teaser photos. The psychedelic lighting job on the car seems a bit on-the-nose for something debuting on 4/20, but again, this isn't a Tesla, so clearly somebody just thought it would look cool. Fortunately, we have the bZ4X's spec sheet to go on. The 4,232-pound Toyota is powered by a single electric motor with 201 horsepower or a dual-motor setup with 214 horses (107 per motor). Clearly, getting all-wheel drive into the equation mattered more than performance, as Toyota says it'll still take 7.7 seconds for the bZ4X to hit 60.  Regardless of motor count, the bZ4X gets a 71.4-kilowatt-hour lithium-ion battery pack said to deliver about 310 miles of maximum driving range in the front-wheel-drive model and 285 miles in the all-wheel-drive version based on the Japanese testing cycle. It's not outrageous to think the RZ might get a more potent powertrain, but we'll just have to wait and see what Lexus has in store.  Related video: This content is hosted by a third party.
