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.

Toyota announces two recalls affecting 1M Corolla, Matrix and Lexus IS models

The recall bug strikes Toyota again. The automaker has issued a voluntary recall of three models that, in total, represent more than one million units. Around 752,000 2003-2004 Toyota Corolla and Matrix models are being recalled for airbag concerns, while a windshield wiper issue is causing the recall for close to 270,000 Lexus IS sedans from the 2006-2012 model years.
Completely unrelated to the small airbag-related recall issued earlier in the week, the Corolla and Matrix recall is caused by a faulty airbag control module that could potentially short circuit, which could lead to the front airbags or seat belt pretensioners deploying. The Lexus recall is due to a wiper arm nut that wasn't tightened properly, which can cause the wipers to not work when trying to clear heavy buildup such as snow.

Lexus RC F and GS F 10th Anniversary Editions are all black and blue

Lexus's F marque, the letter affixed to sport-tuned and performance models, debuted just over 10 years ago when the IS F hit dealer showrooms. The V8-powered sedan was a direct competitor to the tried and true BMW M3. The IS F was followed by the V10-powered LFA, RC F coupe and GS F sedan. In celebration of the F sub-brand's 10th anniversary, Lexus is rolling out two new limited edition variants of the RC F and GS F. In America, only 240 RC Fs and 100 GS Fs will be available. There is a price to pay for exclusivity. The RC F 10th Anniversary Edition starts at $80,810, a $16,160 premium over the standard model. It's not just special badging. The new model comes standard with the Performance Package, Triple Beam headlights and Intuitive Park Assist. Those three options will run you $7,160 on their own. At $89,350, the GS F 10th Anniversary Edition is only a $5,000 premium over the standard model. Both cars come with matte Nebula Grey paint, 19-inch black BBS wheels wrapped in Michelin Pilot Super Sport tires, and Brembo brakes with blue calipers. The RC F has blue leather seating with white accents up front as well as blue accents on the shift knob, steering wheel and instrument panel cover. The GS F gets blue leather seating both front and rear. There are blue carbon-fiber accents, blue suede on the dash and blue seat belts. Additionally, the GS F gets blue leather on the steering wheel, console and shift knob. The RC F and GS F are still powered by a 467 horsepower naturally-aspirated 5.0-liter V8. Power is sent to the rear wheels through an 8-speed automatic transmission. Both cars also pack a torque vectoring differential. Look for these special edition models later this year.
