NHTSA may investigate new Toyota unintended acceleration case

After paying a $1.2-billion settlement to the US government last year, Toyota largely put the unintended acceleration recall behind it. Although, there were still some civil lawsuits to handle. A new case where the owner of a 2009 Lexus ES350 is petitioning the National Highway Traffic Safety Administration to open another analysis could draw the issue back to the forefront. Investigators are still deciding whether to research these claims further, though. According to this petition, the owner's wife was driving the ES350 in February 2015. While pulling into a parking space, the sedan allegedly surged forward, and there was a low-speed accident. The claim asserts there are at least two other similar cases in NHTSA's database: one in a 2009 Camry in 2009 and another in a 2010 Corolla in 2014. Specifically, this person wants an "investigation into low-speed surging in different models of Toyota automobiles in which the car starts accelerating and the engine RPM increases even when the accelerator pedal is not depressed," according to the agency. NHTSA will do further research into this person's claim and will decide whether to conduct a full investigation into the alleged issue. This won't be the first reappraisal of unintended acceleration in Toyotas by the agency in recent months, though. Between September 2014 and May 2015, NHTSA evaluated a similar petition with allegations covering 2006-2010 Corollas, and the government body decided to deny that one because the problem couldn't be replicated.

The petition was prompted by a February 2015 crash involving a model year (MY) 2009 Lexus ES350, which allegedly surged as the petitioner's wife was pulling into a parking spot.

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.

Lexus to reveal new concept in Geneva

When Lexus rolls in to the Geneva Motor Show this year, it will have some exciting metal to show off to the Old World crowds. Both the GS F performance sedan and the LF-C2 concept will be marking their European debuts at the Swiss expo. But it will have a new concept to showcase, as well. Just what form that concept will take is anyone's guess at this point, and Lexus isn't saying. The Japanese luxury marque's lineup consists primarily of sedans and crossovers, with the RC coupe and CT hybrid hatchback thrown in for good measure. The likelihood is that we'll be looking at either a new compact model or a large crossover, but that's all up in the air at the moment. Recent show cars from Toyota's upscale brand have included the RC F GT3 racer, the aforementioned LF-C2 convertible, the LF-LC sports coupe and the LF-NX concept that previewed the new NX compact crossover.

World Premiered at this year's Detroit MS, the GS F is a refined four-door coupe with the speed and agility of a premium sports car. Equipped with a normally-aspirated 5.0l V8 engine, the GS F produces maximum power of 477PS and maximum torque of 530Nm. The GS F is the first Lexus to include the new comprehensive Lexus Safety System +. World Premiered at 2014 Los Angeles Motor Show, the LF-C2 concept will also have its European Premiere at this year's Geneva MS. The concept is a design study in the form of a 2+2 roadster that explores key styling themes involved in the Lexus brand's future, bolder styling direction. The LF-C2 is a luxury Grand Touring concept inspired by Lexus' passion for driving. Its open-air design derives from a pure sports coupe idea. Finally, during the Lexus press conference, a new Lexus concept will have its World Premiere. The Lexus Press Conference will take place on March 3, at 12:30 at the Lexus stand (number 4211) in Hall 4.
