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 LC Convertible Concept is likely headed for production

The Lexus LC works quite well as a stunning halo car for the Japanese brand, and we're big fans of the coupe's design, both inside and out. So we're excited by the prospect of the car you see above, which Lexus will officially unveil in just a few days at the 2019 Detroit Auto Show. As it sits, the Lexus LC Convertible is a concept vehicle, but judging by statements from company executives, production is practically a foregone conclusion. "This concept takes the unmistakable design of the LC coupe and reimagines it as a future convertible," Tadao Mori, chief designer of the LC Convertible concept, hints in the press release that accompanied this announcement. He adds, "A production version of this concept would be exhilarating in many different ways." Even if this concept is little more than an LC Coupe with its roof lopped off, the result is still very pretty. The droptop sits low to the ground on 22-inch wheels. Inside, elegant white leather dramatically contrasts with yellow stitching and dark-colored trimmings. The automaker isn't saying what's under the hood, but we'd guess a production version would offer both gasoline-fueled and hybridized powertrains similar to the coupe. Stay tuned for live images from the show floor in Detroit. Related Video:

Lexus takes to Pikes Peak in RC F GT Concept

Lexus is gearing up to take on Pikes Peak with the RC F GT Concept you see here, developing the new racing prototype for the venerable hillclimb event. Different from the more extreme GT3 and GT500 racing concepts we've seen to date, the new GT concept is more closely based the road-going RC F. Only it's leaner and meaner and ready to take on the grueling 12.4-mile race to the clouds and all its 156 turns. The RC F GT packs the same 5.0-liter V8 and eight-speed automatic transmission as the production model. The major difference is that it weighs some 800 pounds less, thanks largely to the widespread use of carbon fiber body panels and polycarbonate windows. It also incorporates a more aggressive aero kit and rolling stock, and allows the technicians to tune the engine for competition applications. To tackle the Peak, Lexus is handing the keys over to none other than Justin Bell, the former GT2 class winner of the 24 Hours of Le Mans and the FIA GT Championship. He'll be fielding the RC F GT in the Time Attack class for production-based vehicles, while providing Lexus engineers with valuable performance data and the chance to develop components for future applications. Two years ago, the IS F CCS-R prototype competed in the same event, and served as a test bed to develop the powertrain that went into the RC F that followed.

(June 22, 2015) – On June 28th, Lexus will compete in the Time Attack class of the Pikes Peak International Hill Climb. The luxury automaker will be campaigning the all-new RC F GT Concept, a vehicle that builds upon the legacy of the IS F CCS-R vehicles that last competed at Pikes Peak in 2013. This historic event, now in its 93rd running, is a race against the clock that tests man and machine with the changing elements, altitude, and a treacherous 12.42 mile, 156 turn course that winds up the peak from 9,390 feet up to the 14,115 foot summit. The new Lexus will be piloted up the mountain by British driving ace, 24 Hours of Le Mans winner, and automotive media personality Justin Bell. "With very little time behind the wheel, the RC F GT Concept has already proven fast and easy to drive, very much like the production models, actually.
