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 Lexus LC 500h is a wonderful mechanical mishmash

Lexus is following up on the Detroit debut of the LC 500 with a Geneva debut for a new hybrid model that, yes, has a four-speed automatic. We're still getting used to the idea, too. But as we've explained before, even with the old-school gearbox there's some real cutting edge stuff going on here. While the LC hybrid will have a four-speed auto, it will work in conjunction with an eCVT, a Lexus hybrid system, and possibly black magic. It's all very complicated – you can get particulars here – but it's best to think of the LC 500h's transmissions not as a CVT and a four-speed auto, but as a sort of ten-speed hybrid of the two, since both systems are always engaged. The hybrid system is much more familiar. There's a 3.5-liter V6, a battery pack, and two electric motors. Total system output is 354 ponies and Lexus claims the sprint to 60 mph will be done in under five seconds. For the record, the gas-only LC is projected to do the deed in around 4.5 seconds, so the hybrid shouldn't be a dramatic compromise in terms of performance. Of course, stats only tell so much. The ultimate question for the LC 500h is how its wild mix of transmissions, batteries, motors, and an engine will behave on the road. We don't have an answer for that yet, but we do have live images of the new hybridized Lexus at the 2016 Geneva Motor Show. Check them out.

The LC 500h is equipped with Lexus' next generation hybrid powertrain, the Lexus Multi Stage Hybrid System, providing enhanced driving pleasure, more performance, and greater efficiency. The LC was first revealed at the 2016 North America International Auto Show. Its styling, performance and craftsmanship position the vehicle as Lexus' flagship coupe. The LC also utilizes Lexus' new architecture that promises enhanced dynamic capability. Inspired by the acclaimed LF-LC concept that debuted in 2012, the LC represents a shift in Lexus' engineering processes and design ideologies, and marks the beginning of a new phase for the Lexus brand.

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.
