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.

BMW-Toyota partnership to spawn hybrid supercar

BMW and Toyota inked a partnership some time ago to develop green technology, and while we were excited by the idea of a reborn Supra with BMW's carbon fiber reinforced plastic slashing the curb weight or an ultra-efficient, hybridized 1 Series, the joint efforts have been rather limited. That's set to change, though, according to a report from Australia.
Motoring reports that the partners have come to terms on a sports car. And not just any sports car, but a lightweight, hybridized model, with a six-figure price tag. Lending a bit of street cred to that idea is the site's claim that Toyota is currently carrying out durability testing on the BMW i8. According to the site, the new model will slot into the spot left by the Lexus LFA, although based on the language used, it's unclear if this is the Tokyo-bound vehicle we mentioned several months ago.
Details on this potential car are limited, although Motoring claims it will use a Toyota hybrid system mated up to a BMW gas engine - likely the 4.4-liter, twin-turbo V8 found in the M5 and M6. That sounds pretty amazing to us, but we'd still advise taking this with a grain of salt. What would you like to see out of a joint-venture supercar from Toyota and BMW? Let us know in Comments, and have your say on the prospects of a hybridized, twin-turbocharged V8.

Lexus GX, Toyota Land Cruiser Prado facelifts leaked

The Lexus GX and the Toyota Land Cruiser Prado, which isn't sold in the US, have gone without visual updates since the current generation was launched in 2009. But what appear to be patent filing sketches and pictures of the sibling sports utility vehicles' mid-cycle updates have been leaked on a Russian Land Cruiser Club forum.
Major changes to the GX's front end will be made to incorporate Lexus' signature grille. Gone are the awkwardly shaped headlamps and the soft-looking triple-slat grille. The sketch shows the Lexus with a new bumper, lower-profile headlights and a more aggressive, angular grille with one more slat and a gaping lower air-intake opening. The vehicle's profile looks unchanged, but the rear bumper will be reshaped slightly to fit new, better-integrated horizontal reflectors.
The Toyota gets a handful of styling updates as well, including a new front bumper with higher-profile headlamps that look a bit out of place to us. The Prado's profile also looks unchanged, but the rear end gets restyled taillights and a reshaped license-plate enclosure.
