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.

Did Lexus make a BMW? Or did BMW make a Lexus? This and other 2017 surprises

It's that time of year again. The calendar is about to reach its end, Star Trek Cats 2018 is about to take its place, and I'm reflecting about all the cars that graced my driveway this year or summoned me to exotic places. You know, like Stuttgart or Phoenix. In 2017, I drove at least 57, and as I perused the list of them, I started to notice a common refrain: "This car surprised me." Most were pleasant surprises, but there were a few head scratchers and facepalms for good measure. In both cases, it was generally the result of car companies seemingly trying to break out of an existing mold. Nowhere was that more apparent than the pair of Lexuses slathered in Infrared paint: The LS 500 that left me this week and the LC 500 that was my favorite car of 2017. Though Lexus has been trying to shake its crusty, gold-packaged reputation for some time now, its efforts always seemed like an old man choosing Hollister to redo his wardrobe after realizing it hasn't been updated since 1987. I fell in love with the LC, genuinely floored by its near-perfect take on the GT. It's characterful in sound, appearance and tactility. It was at home in the city, in the mountain and on the open road. It was both comfortable and thrilling, and after driving the mechanically related LS 500, I can report that the LC's talents aren't an outlier. The LS 500's turbo V6 may make different noises than the LC's naturally aspirated V8, but it nevertheless invigorates the cabin when the car is placed in Sport+ mode. The steering is truly communicative, body motions are kept in miraculous check, and I absolutely forgot I was in an enormous luxury limo ... and a Lexus one at that. It was everything that the BMW 530e was not. I drove that on the exact same roads and was utterly bored the entire time. Generally doughy, lifeless steering, more distant than Planet 9. And no, the plug-in hybrid powertrain had nothing to do with that. At least it shouldn't. The Porsche Panamera S e-Hybrid I also drove this year proves that, as do the Hyundai Ioniqs, which are surprisingly adept and fun little cars regardless of what powers their wheels (Hyundai + hybrid = fun really blew me away). I would drive that Lexus LS F Sport over the BMW 5 Series any day of the week, which seems like a shocking thing to say in relation to either car. While Lexus is seemingly breaking out of its old crusty mold, BMW seems to be climbing into one.

Lexus exploring PHEV, full EV and fuel cell versions of LS flagship

After four years of rumors about a Lexus LS powered by a hydrogen fuel cell, the chief engineer of the flagship sedan says the carmaker's working on even more options. Toshio Asahi told Australia's GoAuto that three alternative powertrains — plug-in hybrid, full electric, and hydrogen — are "all on the table" for consideration. Asahi wouldn't give any timeframes, but whenever they arrive, additional drive options would fill out the LS range to better contend with the Germans. Years of reports predicted this fifth-generation LS would get hydrogen power. A Motoring article at the end of 2014 forecast a fuel cell LS to arrive by 2017. In 2015 Japan's Nikkei newspaper reported that Lexus was considering a fuel cell option to arrive in 2020, around the time of the Tokyo Olympics. Later that year, at the Tokyo Motor Show, Lexus showed off the LF-FC concept, powered by a cell and stack arranged for "optimum front-rear weight distribution for a sporty saloon." GoAuto said that during that show, a Lexus executive said an FCEV powertrain would end up in production "sooner than you think." The following year, Autocar reported we'd see a production version of the LF-FC "on sale before 2020" as a replacement for the LS, and last year, Lexus trademarked the name "LF-FC Concept." The intel gets murkier regarding plug-in hybrid and full electric versions. We now know Lexus is working on a more powerful hybrid system. The current hybrid produces a total system 354 horsepower and 258 pound-feet of torque using the same 3.5-liter V6 in the standard car as a base, though the standard car adds two turbos for 415 hp and 442 lb-ft. The coming hybrid will likely use the twin-turbo setup and could achieve two important ends: Smoothing out noted issues of powertrain refinement, and at least matching the power specs of Mercedes-Benz and BMW flagship plug-in hybrids. That hybrid LS would still miss out on the all-electric driving of its rivals. If there really is an LF-FC coming in the next two years, it would seem a perfect time to retire the conventional hybrid and introduce a plug-in version embodying the velvet sophistication Lexus is known for. The battery electric LS is a big question mark outside of Lexus HQ. Last year Toyota announced a breakthrough in solid state battery technology, the carmaker announcing it wanted such batteries on the market by 2022.
