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 RX replacement to debut in Detroit?

The 2015 Detroit Auto Show is shaping up to be a big one for Lexus, with Group Vice President Jeff Bracken confirming to Ward's Auto that the Japanese luxury marque will have at least one, and possibly two, all-new-model introductions. Ward's seems to think that one of those vehicles will be the new RX crossover, one of the brand's most popular (and oldest) offerings. The complete and utter lack of spy photos of the new RX doesn't necessarily support Ward's argument, although if the new CUV ends up being based on the JDM Toyota Harrier, as previously reported, the absence of camouflaged images might make some sense. As for that other vehicle, it's hard to say what we might see. Were we to put our money on it, though, the long-awaited GS F would be a strong contender for a Detroit debut. The high-performance challenger to the BMW M5 and Mercedes-Benz E63 AMG has been spotted almost completely undisguised as recently as October. On top of that, Detroit's reputation as a performance-focused show (last year's show saw debuts of the Ford Mustang, BMW M3 and M4, Chevrolet Corvette Z06, Volkswagen Golf R and Porsche 911 Targa) makes the GS F's appearance there a fair bet. One thing we can count on at least hearing about when Detroit rolls around is Lexus' strong sales position. The company's 2014 sales should crest 305,000 units by the end of the year, marking the first time the company had passed the 300,000-unit mark since 2007. Bracken told Ward's that should be an easy task, particularly with the brand's "best month of the year," December, still to come.

2016 Lexus GS F First Drive [w/video]

Performance cars used to be about horsepower and chassis tuning. Lately the question isn't so much what's under the hood, but how many buttons are on the console. We're overwhelmed with individual settings for engine response, transmission, exhaust, steering, and ride. When did these cars turn into a choose your own tuning adventure? The Lexus GS F represents an attempt to step back from this over-adjustable madness and return to more bygone sports car values. It has a special engine, unique bodywork, and a chassis tuned for high performance. There are only two settings you need to play with. The first setting is the Drive Mode Select dial on the center console, which mainly controls the response of 5.0-liter V8 engine and the shift behavior of the eight-speed automatic. The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. New this year are small balancing weights on the crankshaft pulley that cut down on internal vibration. Drive Mode Select also changes the electronic power steering, air conditioning, and stability control (you can also turn it all the way off via a separate button). The engine is the same V8 found in the RC F, making the same 467 horsepower and 389 pound-feet of torque. You will use two settings in the GS F: Eco when you want to get somewhere, Sport S+ when you want to get somewhere fast. Normal and Sport S modes offer intermediate steps you don't really need. Eco mode softens the throttle and reduces the use of air conditioning for slightly better fuel economy. It also makes the center-mounted tachometer switch into an eco-driving gauge. S+ puts everything into sport mode, including a heavier steering weight and a higher stability control threshold. While Sport S mode shifts the noon position of the tachometer to just below the horsepower peak of 7,000 rpm, S+ goes a step further and turns the rev indicator into a solid bar that grows around the edge of the display. It also adds oil and coolant temperature to the readout. And how could we fail to mention G-Force Artificial Intelligence (or grin at such an overwrought name)? That's the shift logic the transmission uses in Sport S+. It's designed to hold revs in corners and downshift during hard braking. "Our goal with F is to make a driver's car, not a drag race winner." The other button in the Lexus GS F that you need to pay attention to is next to the Drive Mode Select knob, labeled TVD for Torque Vectoring Differential.
