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 500 Aviation adds some aeronautic flair for 70 lucky owners (in Japan)

In our experience, there's a notable overlap between enthusiasts of fine automobiles and aviation. Lexus seems to think so too, which is why it is releasing a plane-themed version of its flagship sport coupe. The Lexus LC Aviation will come in both LC 500 and LC 500h form, and features an aeronautic-inspired centerpiece on the rear decklid. That would be a curved carbon fiber reinforced plastic (CFRP) spoiler that follows the trailing edge arc of the trunk, with two downturned winglets on either end. Lexus says the winglets are functional, generating a vertical vortex that smooths out the turbulence generated from airflow along the car's flanks. The result is improved yaw and steering response, comfort, and stability at high speed. The wing itself is made by craftsmen from the LFA project, which famously created and used a 3D carbon-fiber loom to weave parts of the V10 supercar's body. Part of the development was conducted with Yoshihide Muroya, an acrobatic pilot and winner of the 2017 Red Bull Air Race Championships. The rest of the package includes beautifully slim, black, 21-inch split-spoke wheels that you won't find on the standard LC. The trademark "spindle" grille has been blacked out as have the side vent moldings, and head and taillight garnish. The cabin comes in an exclusive color Lexus calls Aviation Black, while other tidbits, like an Alcantara steering wheel, shift knob and door trim, as well as saddle-colored highlights, finish off the cabin. There are no powertrain upgrades.  The only three colors are available are silver, white, and black. Alas, only 70 units will be produced for the Japanese market. It goes on sale Jan. 6, 2021.

Lexus' LFA Works now making carbon fiber bicycles... kind of

The LFA Works that produced the Lexus LFA hasn't had too much to do since the 500th example of the V10 supercar left the plant on December 15, 2012. So what are a bunch of carbon fiber experts meant to do with their time when they have some of the world's most advanced CFRP machinery but no engine to wrap it with? Why, make a bicycle, of course - and not just any bicycle, but the kind that costs one million Japanese yen ($10,000 US) and of which only 100 will be made.
Only they didn't really "make" it - the carbon fiber frame was sourced from Takumi, in Taiwan. On the face of it that's a shame, but it makes sense; when you've got a company like McLaren assisting bike manufacturer Specialized produce a road bike, it's clear that 'pushies' have got so advanced that a company can't just hop in and mold a $10K bike in six months. Beyond that frame it's got a Shimano Dura-Ace Di2 group with electronic shifters, and it weighs 15 pounds.
However, the Lexus crafstmen did polish each frame for three hours, and the bike is said to embody the "principles and philosophy" of the supercar, while the brochure for the bike says it represents "a new chapter in Lexus history." That chapter is still all about rarity, though, since there's only one bike headed for Canada and two for the US.
