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.

2014 Lexus IS gets TRD bits

Toyota Racing Development (TRD) in Japan has designed cosmetic and performance bits that give the 2014 Lexus IS a front-to-back workover. Different from the F-Sport parts we expect from Lexus here, the full body kit runs 437,700 yen ($4,285 US) and starts with air deflectors at the lower edges of the front bumper, through to side skirts, a decklid spoiler and a rear bumper with a diffuser and quad exhaust tips.
For 288,750 yen ($2,830) you can sharpen responses with new shocks, springs, dampers, sway bar and bracing. The priciest individual component is the set of 19-inch wheels, four of them going for 527,625 yen (5,170 US). There's no word on US importation or pricing yet, but done up all in black like the IS above, we wouldn't mind seeing it here.

Massive Airbag Recall Affects Seven Automakers

The recall of faulty airbag inflators supplied by Takata has exploded today to grow to seven automakers. In most cases, only models in certain high-humidity regions were affected because the National Highway Traffic Safety Administration found in its investigation that moisture played a role in determining whether there would be a problem. However, some companies opted for national campaigns. The exact number of affected models for these campaigns isn't yet known at this time. BMW is recalling an undisclosed number of 325i, 325Xi, 330i and 330Xi models from the 2001 through 2005 model years and the 2001-2006 model year versions of the 325Ci and 330Ci for the driver side and passenger side inflators. Only vehicles currently registered in Florida, Puerto Rico, Hawaii and the US Virgin Islands are covered under this recall. Neither Chrysler's filing with NHTSA nor its press release list the specific models affected, but a company spokesperson told Autoblog that at this time it only covers the driver and passenger side inflators for the 2006 Dodge Charger in Florida, Puerto Rico, Hawaii and the US Virgin Islands In most cases, only models in certain high-humidity regions were affected because the NHTSA found that moisture played a roll in determining if there would be a problem. Ford is recalling an estimated 58,669 cars that include the 2005-2006 model years of the Ford GT for the driver and passenger inflators, the 2007-2007 model years of the Mustang for the driver side and 2004 Ranger for the passenger side. It covers vehicles originally sold or currently registered in, wait for it... Florida, Puerto Rico, Hawaii and the US Virgin Islands. Honda is issuing three separate recalls regarding the problem. First, the company is recalling the 2002-2003 model years Civic, CR-V and Odyssey and the 2003 model year of the Accord, Element, Pilot and Acura MDX to replace the passenger's side inflator. This covers all models nationwide. Second, Honda is repairing the passenger's side airbag inflator in the 2003-2005 Accord, Civic, CR-V, Element, Pilot, the 2003-2004 model year versions of the Odyssey, the 2003-2005 model year Acura MDX and 2005 Acura RL. However, only for vehicles located in Alabama, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico and the US Virgin Islands. Owners will be notified in July. Finally, Honda is separately replacing some models' driver's side inflators.
