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.

Krafcik says US Gov. shutdown is slowing Oct. auto sales

The government shutdown is eroding consumer confidence in the auto market, says John Krafcik, CEO of Hyundai's US sales unit, and could lower October sales by as much as 10 percent, Automotive News reports. "It's that anxiety that keeps customers, potential buyers, on the sidelines when making a big purchase like an automobile," Krafcik says, adding that industry sales could be off by five to 10 percent in October compared to September.
The fourth quarter, which started October 1, usually consists of increased auto sales as dealerships clear their lots to make room for the next year's models. Leading up to the fourth quarter this year, the auto industry was doing well in the fragile, recovering US economy, although September deliveries decreased by 4.2 percent, due in part to this year's Labor Day sales being recorded for August.
To help its customers, Hyundai announced it is deferring new-car loan and lease payments for furloughed federal workers until they're called back to work and also offering them a three-month payment deferral if they buy a new Hyundai in October. "We have already had requests from over a thousand people to have their payments deferred," Krafcik says.

The revolutionary Bose suspension that could have been

The Bose name pops up on these pages every once in a while – usually, as you might expect, because some automaker or another has installed its audio systems in one or more of its models. But a few years back, the research-driven audiophiles at Bose developed a revolutionary adaptive suspension system that could have been a game-changer. Sadly, it wasn't. The Bose suspension system was a technological breakthrough. As you can see from the pair of Lexus LS sedans demonstrated (and the Porsche Cayman thrown in for good measure) in the two-minute video above from CNET, the system virtually eliminated body roll and smoothed out bumps in the road to near glass-like serenity. It could even jump over minor obstacles. Unfortunately, the system was too heavy and expensive to put into production, and the project was shelved. Instead, it was repackaged into a suspended driver's seat for heavy-duty, long-haul trucks and called the Bose Ride System. It's said to significantly reduce fatigue and back pain while encouraging driver alertness and wellness – which is all well and fine, but a far cry from what the suspension system could have meant for the automotive industry. Just think about that the next time you notice the Bose logo on the speaker grille in an upscale vehicle from the likes of Audi, FCA, GM, Mazda, or Nissan – all automakers that offer Bose audio systems, and which might have considered implementing the advanced suspension if only it were more practical for production.
