Why Lexus shies away from plug-in hybrids

Lexus may have softened its stance a bit from the anti plug-in vehicle ads the Toyota luxury badge ran last year, but at least one executive from the company casts a pretty critical eye towards the concept as a way to cut both emissions and refueling costs. In fact, Lexus doesn't really buy the fact that buyers of plug-in hybrids are really looking to save both gas and the environment, Green Car Reports says, citing an interview at the recent New York Auto Show with Lexus executive Mark Templin. Templin also said hydrogen fuel-cell technology may be a better way to edge towards zero emissions. Templin decried plug-in hybrid technology because it adds weight to vehicles, which contributes to poor emissions figures in the process. He added that plug-in vehicle buyers are motivated more by potential tax credits and solo driving rights in high-occupancy vehicle (HOV) lanes than cutting back on fuel use. Last summer, Lexus ran an supposedly tongue-in-cheek print ad poking fun at how long it takes to charge a plug-in vehicle and how using air conditioning can shorten a car's charging range. Last spring, Lexus had to backpedal from an anti-electric ad it ran that had serious mistakes about hydrogen infrastructure. News Source: Green Car Reports Green Lexus Toyota Hybrid PHEV

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.

Lexus recalling 3,000 NX 200t CUVs for faulty brake system part

Lexus is recalling about 3,000 examples of the 2015 NX 200t in the US because of possible damage to the ABS actuator during assembly. On vehicles with the faulty part, the anti-lock brakes, traction control and stability control might not function properly. If the ABS is activated while driving, it could cause "a loss of vehicle stability," according to the company. No crashes, injuries, or fatalities have been reported. According to company spokesperson Cindy Knight to Autoblog, affected owners will receive notification by mail of this problem in early July. Dealers will inspect the actuator on the NX200t and will replace it, if necessary. Related Video: LEXUS RECALLS CERTAIN MODEL YEAR 2015 NX VEHICLES TORRANCE, Calif., May 27, 2015 – Toyota Motor Sales, U.S.A., Inc. today announced that it is conducting a safety recall of approximately 3,000 model year 2015 Lexus NX 200t vehicles. The involved vehicles are equipped with an Anti-Lock Braking system (ABS), Traction Control System (TRAC), and Vehicle Stability Control System (VSC) which are controlled by the ABS actuator. There is a possibility that a component inside the actuator could be damaged during assembly and later not operate properly. Under some driving conditions, if the ABS is activated, this could cause a loss of vehicle stability, which can increase the risk of a crash. To date, Toyota is not aware of any crashes, injuries or fatalities caused by this condition. All known owners of the involved Lexus vehicles will be notified by first class mail. Lexus dealers will inspect the ABS actuator and if necessary replace it with a new one. Information about automotive recalls, including but not limited to the list of involved vehicles, is subject to change over time. For the most up-do-date recall information, customers should contact Toyota Customer Service at 1-800-331-4331, or Lexus Customer Service at 1-800-255-3987.
