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.

TMG Lexus LS Sports 650 destined for production after 2015?

There's little question that Lexus has succeeded in challenging its German rivals in the luxury marketplace. And with the LFA, it has proven that Japan can build a world-class supercar. What's left blank is the space in between.
Toyota Motorsport GmbH came up with a compelling answer in the form of the Sports 650 prototype, a Lexus LS with a 5.0-liter twin-turbo V8 producing 641 horsepower and other go-fast components to challenge the likes of the Mercedes-Benz S63 AMG and Audi S8. Toyota boss Akio Toyoda was reportedly so impressed with the project that he initially ordered TMG to build ten examples - one for him and each of his nine best friends. But since the model on which the project was based has since been replaced, questions remain over the project's fate.
Georg Kacher - European correspondent for Automobile and Car magazines - recently drove the prototype and reports that "the project will now likely be transferred to the new model out in 2015." That could come down purely to speculation, but Kacher tends to get the inside line on industry news, so this particular bowl of gossip soup might not requite the usual grain of salt we otherwise might add.

Lexus crafts working IS sedan out of cardboard [w/video]

People make model cars out of all sorts of material: wood, plastic, metal... and sure, even cardboard. What sets this one apart is that it's built to scale – as in, full scale – and what's more is that it can actually be driven. Then again, we couldn't vouch for its crashworthiness, so that might not be advisable. The replica Lexus IS sedan was commissioned by the Japanese automaker's UK office and made by two British workshops: Scales & Models and LaserCut Works. It's inspired by the Japanese art of origami and made out of cardboard, except for the working parts and the frame made of steel and aluminum. It's got a fully functional interior, opening doors, working headlights, rolling wheels, and an electric motor. The form is made up of cardboard 10 millimeters (0.4 inches) thick, provided by packaging company DS Smith. The material was laser-cut into 1,700 components, according to a 3D digital model provided by Lexus, and assembled by hand and painstakingly fixed into place by water-based wood glue that has to set for 10 minutes between each step. Little wonder that the whole project took three months to complete. The finished product will be on display at the NEC in Birmingham later this week during the Grand Designs Live Show.
