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.

2018 Autoblog Technology of the Year finalists

After months of prepping and several days of testing, we narrowed the field for Autoblog's 2018 Tech of the Year award to the Nissan Rogue with ProPilot Assist semi-autonomous driving system, the Lexus LC 500h and its new hybrid powertrain, and the Chevy Colorado ZR2 and its trick Multimatic spool-valve off-road shocks. Three very different cars with very different technologies duking it out for the award. Look for news of our winner at the 2018 Detroit Auto Show. We hand out this award every year to the technology or feature that we feel moves the bar forward for the automotive industry. Read more here on how our testing process works. We discuss, debate and count up score sheets, judging each vehicle and technology on a few different criteria. Is its purpose noteworthy? Does it work well? Does it advance the industry? The Nissan Rogue with ProPilot Assist was actually a prototype, as the technology will first debut in the 2018 Nissan Leaf. Still, we're here to test the tech and not the car. ProPilot Assist combines adaptive cruise control system combined with lane-keeping assistance. The system uses sonar, radar and a number of cameras for some light semi-autonomous driving and enhanced safety. While these systems aren't new individually, Nissan's system is affordable, intuitive, and coming to a mainstream product — democratizing the tech in a novel way, if you will. That's why it's here. The Lexus LC 500h uses a new powertrain that Lexus has dubbed the Multi-Stage Hybrid System. Basically it combines two types of transmissions — a CVT and a four-speed automatic — in a single unit mated to a naturally aspirated V6. That's complex and unorthodox technology, and Lexus engineered it to give drivers the efficiency of a CVT without sacrificing driving enjoyment. The package is subtle, working in the background to create a nearly seamless driving experience. It's engaging in a way most other hybrids can only dream of. The fact that it's wrapped in such gorgeous sheetmetal only makes things better. The Multimatic spool valve shocks in the Chevy Colorado ZR2 might seem low-tech compared to ProPilot Assist and the Lexus Multi-Stage Hybrid, but they represent a completely novel application of a technology that several years ago was so expensive that it was reserved for top-tier race cars. Like the LC 500h, these shocks really change your perception of how a vehicle like this should drive.

Lexus IS 200t gets a 245 hp turbo four-cylinder, comes here in 2016

The exact timing isn't clear, but now that we have the good news we're ok with a little wait: in Europe Lexus just replaced the 2.5-liter V6 in the IS 250 with its 2.0-liter, turbocharged four-cylinder, and we'll get it. The 2.0-liter currently serves in the NX 200t, putting out 235 horsepower and 258 pound-feet. Car and Driver says it will be tuned differently for what will become the IS 200t, with an output of 241 hp and 258 lb-ft. Those numbers whoop the 2.5-liter V6 by 37 hp and 73 lb-ft, and they're just 65 hp and 19 lb-ft under the 3.5-liter V6 in the much more popular IS 350. Improvements continue in the transmission, the IS 200t getting eight cogs - there won't be a manual option - instead of the six-speed 'box mated to the 2.5-liter now. That means buyers can expect a car that's not only more powerful and more responsive, addressing the two fundamental omissions in the IS 250's list of talents, it will also get better fuel economy than the 21 city, 30 highway miles per gallon the old six-cylinder musters. What they can't expect according to CD is all-wheel drive. We're told the engine swap should come "in the early part of the 2016 model year," and it will only come with rear-wheel drive. C/D says that Lexus will bring a third engine to the range that will power an all-wheel entry, which seems a tad complex to us, but if true it wouldn't be the first time the words "Lexus" and "complex" have cozied up together. A press release from Lexus Europe is below. LEXUS TO LAUNCH IS 200t WITH INNOVATIVE 2.0l TURBO PETROL ENGINE • New turbo engine offers superior smoothness and responsiveness, with no turbo-lag and high fuel efficiency • Engine mated to 8-speed Sport Direct Shift transmission • IS 200t on sale in Europe as from September 2015 Brussels, Belgium, 26 Jun 2015 - Lexus is expanding the range of vehicle equipped with its new 2.0-litre turbo engine. Following the launch of NX 200t in early 2015 and the announced arrival of RX 200t by the end of the year, IS is the third Lexus model to be fitted with this new engine. Powered by a new 2.0-litre petrol turbo engine – with innovative D-4ST fuel injection technology for both fuel economy and instantaneous torque – the Lexus IS 200t sports sedan delivers 245 DIN hp (180kW) with a maximum torque of 350 Nm. Capable of rapid acceleration up to a top speed of 230 km/h, its 8-speed Sport Direct Shift transmission was developed for the high-performance RC F.
