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 jumps head first into turbocharging with its 2015 NX 200t

If Lexus is going to stay competitive, it needs to turbocharge sooner rather than later.
If there's anything that Lexus is experienced with, thanks in large part to its corporate parents at Toyota, it's hybrid powertrains. The automaker has hybridized tiny little four-cylinder engines, massive honkin' V8s and everything in between. So synonymous are hybrids and Lexus that it would be a shock to see a brand-new model released without an accompanying version with blue badging and a little "h" appendage to its name.

Lexus gets new boss, and he's a designer

A reshuffle in the uppermost ranks of Lexus could see the Japanese luxury brand further energize its recent focus on design. Tokuo Fukuichi, Toyota's global design boss, is the new head of Lexus International.
Fukuichi will retain his role as the overall head of design for Toyota, Lexus and Scion, and will assume his new position at the head of Lexus and on its board on April 1 (no fooling). This is going to be an interesting move for fans of design to watch, as Fukuichi has repeatedly been mentioned as a designer that enjoys pushing the edge of the envelope and experimenting. He is, after all, the man responsible for designing the most awesomely odd minivan of the 1990s, the mid-engined, rear-drive Toyota Previa, and more recently, he signed off on the controversial Lexus LF-NX concept, which is said to presage a new production small crossover.
"Regarding changes in design, no one has 100 percent confidence," Fukuichi told Forbes back in January 2013. "No one can really say with pure certainty that, 'In two years, this will sell well.'" As Akio Toyoda continues to demand more assertive, edgier designs, it's that point of view that should make Fukuichi a valuable addition to Lexus, as it continues to challenge the competition from Germany.
