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 IS, new and old, and LFA to make splash at SEMA

Lexus has announced its Specialty Equipment Market Association (SEMA) show cars: a group of eight Lexus IS sedans spanning all three generations, and a 2012 LFA supercar. One of the show cars, a custom 2014 Lexus IS 350 F Sport, is a creation penned by IS fan Rob Evans, the winner of a contest to design a Lexus SEMA show car.
The standouts in the group of Lexus IS show cars, in no particular order, are a 700-horsepower 2014 Lexus IS 340 (it has a heavily modified Toyota Supra inline six swapped in, which is stroked out to 3.4 liters, hence the nomenclature change) by Philip Case and a supercharged 2004 Lexus IS 300 by Maricar Cortez. Both cars prove that oldies can be goodies - the venerable Supra 2JZTE engine, which ceased production over a decade ago, lives on in a 2014 platform, and the 2004 IS 300 gets a supercharger and remains relevant through the use of electronics, such as a back-up radar sensor, upgraded headlights and more.
Of course, the LFA by Guy S. De Alwis will be a stand out on its own, but unfortunately Lexus only provided us with a couple pictures that don't do it justice. We'll have to take a closer look at it on the show floor. Same goes for the IS penned by contest-winner Rob Evans, of which only a rendering was provided.

2016 Lexus GS 200t First Drive

Last year, Lexus rolled out an ad for its GS that featured several luxury rivals swinging on pendulums, with a hypnotic voiceover that derides the BMW 5 Series' standard four-cylinder engine. The ad then asks viewers to, "Open your eyes to the six-cylinder, eight-speed Lexus GS." Oh, how times have changed. Consider the facelifted Lexus GS 200t and its four-cylinder turbocharged engine an admission that maybe the Germans are on to something. It's good to see Lexus getting with the times, but after a drive in Southern California, we find the first turbocharged GS comes up short in a lot of ways. This is the same engine Lexus uses in the NX, IS, and RC with 200t designations. The 2.0-liter four-cylinder uses a twin-scroll turbo, direct injection, and Toyota's most advanced continuously variable valve timing to produce 241 horsepower and 258 pound-feet of torque. That's 70 horsepower short of the GS 350's 3.5-liter V6. But torque is down only 22 fewer lb-ft, and the 200t's broad peak torque, from 1,650 to 4,400 rpm, promises ample usable power. The 200t offers little reward for the slower acceleration. As for that previously-mocked BMW 5 series, the Lexus has nearly identical output. But a 7.0-second 0-60 time is nearly a full second slower than the BMW's claim for the 528i, a car that weighs practically the same as the Lexus. Fuel economy is another head-scratcher. Lexus estimates the GS 200t F Sport returns just 20 miles per gallon in the city and 30 mpg on the highway, three and four mpg less than the 5er. This brand-new 2.0-liter turbo is hardly more efficient than the three-year-old GS 350. The V6 model nets 19 mpg city and 28 mpg on the highway, and is 1.3 seconds quicker to 60 mph. A smaller engine almost always means sacrificing performance for economy, but based on the figures the 200t offers little reward for the slower acceleration. At least the 200t is better from behind the wheel than on paper. We weren't that impressed by the low-end grunt of Lexus' 2.0-liter turbo when we drove it in the NX, but different gearing in the GS means snappier off-the-line behavior. Once the turbo catches up you're well into the heart of the torque curve, and the GS feels quicker than a seven-second jog to 60 mph. Mid-range punch is the engine's most endearing quality. Passing moves are easy and entertaining, even when you're already traveling at or above freeway speeds. Unfortunately, the engine gasps above 4,400 rpm.
