The Lexus LC 500h has a four-speed auto and that's a good thing

Lexus is sharing some powertrain details on the LC 500h ahead of the big hybrid coupe's debut in Geneva. Its new gas-electric setup strays from Toyota's tried-and-true system found in everything from the Prius to the Lexus GS. It's called the Multi Stage Hybrid System that's designed for performance vehicles, and it has an antiquated-sounding piece of equipment buried deep inside that's supposed to make it more enjoyable to drive. The basics: In the LC 500h, its first application, the Multi Stage Hybrid System will consist of a 3.5-liter V6, a hybrid transmission, and a lithium-ion battery pack. The hybrid transmission has an electric motor for motivation (and we're guessing a second for charging) and a four-speed automatic mounted to its rear, which either means inside or aft and in series. Why add ancient tech to a new hybrid system? Lexus says it preserves the connection between throttle input and engine speed that gets lost in a CVT. And while four seems like an insignificant sum in the face of nine- and 10-speed autos, remember that it is an infinite increase in gear count compared to CVT-packing hybrids. Toyota has been using versions of the Hybrid Synergy Drive system since the first Prius debuted in 1997, and the same system is sold under the Lexus Hybrid Drive banner in most of the luxury brand's offerings. These systems use what Toyota calls an e-CVT – two electric motors paired with a planetary gearset. This lets the engine and electric motors share the job of propelling the car – one motor handles charging of the battery and the other is primarily used to drive the wheels but can also recoup energy through regen. Like a conventional CVT, the planetary gearset arrangement allows the gas engine to run at its optimal engine speed when called upon for motivation and/or charging. But that doesn't make for the most exciting or familiar driving experience, as it affects both power delivery and the sound of the power being delivered. This is where the four-speed auto comes in. Based on the limited details Lexus has shared, our hunch is that the hybrid transmission will meld some form of the existing Lexus Hybrid Drive system with two more planetary gearsets, or the basic guts of a four-speed auto. This will provide the four fixed ratios and the feeling of actual shifting gears – because there will be actual gears shifting.

Toyota Recalling 1.67 Million Vehicles Worldwide

UPDATE: Toyota is now announcing specifically which models are covered under its fuel pipe recall in the US. The company is repairing about 423,000 Lexus models that include the 2007-2010 LS, 2006-2011 GS, 2006-2011 IS, 2010 IS C and 2008-2010 IS-F. The automaker says that it isn't aware of any fires, crashes, injuries or fatalities caused by this problem. According to Toyota, the recall is because it's possible for the fuel delivery pipes and the fuel pressure sensor to form a bad seal with the gasket between them because of a protective coating protecting against corrosion on the pipes. It's possible for this to eventually cause a fuel leak, and obviously in a hot engine bay that's a potential fire risk. To fix the problem, dealers will replace the gasket and repair the gasket seating surface between the fuel delivery pipe and the fuel pressure sensor. The company will begin notifying owners soon. You can find the official press release, below. Toyota is issuing three separate recalls covering 1.67 million vehicles worldwide with most of those models in Japan. It looks like the campaigns' impact on the US may be smaller, though. According to Reuters, Toyota isn't aware of any accidents, injuries or fatalities affecting the models. Some yet-unnamed Lexus models might also be affected. The largest of the campaigns does not currently affect any US-market vehicles. About 802,000 units of the Toyota Crown Majesta, Crown, Noah and Voxy in Japan are being repaired to replace a seal that could leak in the brake master cylinder. Those already leaking get a new brake booster, as well, according to Reuters. The only recall currently believed to affect the US is due to a problem covering approximately 759,000 vehicles with 423,000 of them here. The repair is to fix a faulty fuel delivery pipe that could cause a fire if the fuel leaks out. Unfortunately, we don't know which models it covers. Autoblog spoke to Toyota spokesperson Mona Richard and was told the information was still "under embargo." When exactly that embargo will lift isn't yet known, but we're on the case. Finally, Toyota is recalling 190,000 Corolla Rumion and Auris models in Japan for a faulty evaporative emission control unit. Autoblog is in contact with Toyota, and we'll update this story as soon as we know more about its affect on the US market.

Lexus to replace GX SUV with new TX crossover

There's been a lot of news regarding future Lexus products recently, including spy shots of new RC coupe and NX compact crossover, and reports that a 2+2 coupe based on the LF-LC concept is heading for production. Now, Automotive News says that Japan's #1 luxury automaker is planning to replace the fullsize, body-on-frame Lexus GX SUV with a three-row crossover called the TX.
The article says that the GX, which is based on the foreign-market Toyota Land Cruiser Prado, will get a styling update for 2014 before being phased out in 2016. In a similar move as Infiniti made with its new three-row JX/QX60, the new TX will be car-based, but details are still unknown as to whether it will be front-wheel-drive riding on the Toyota Avalon platform or rear-wheel-drive using the Lexus GS platform. Either way, this new luxury crossover could join the Lexus lineup as soon as late 2016.
