Toyota announces new, more efficient powertrains for 60 percent of its vehicles by 2021

In the face of increasingly strict standards on fuel economy and CO2 emissions, Toyota announced today that it's introducing a new hybrid system, a new 2.5-liter direct-injection inline four-cylinder engine, and two new transmissions – an eight- and a 10-speed. The development of all of these components will be based around the Toyota New Global Architecture, or TNGA. Development of the systems has moved forward and the new powertrains will find their way into vehicles starting next year. TNGA, like Mazda's Skyactiv technology, is a complete design philosophy that focuses on more than just a clean or efficient engine. The first vehicle to deploy the TNGA platform was the current, fourth-generation Prius. With TNGA, Toyota focused on improving handling, ride, and braking performance. The new powertrains are meant to compliment this new platform by being both engaging to drive and fuel efficient. Since TNGA can be adapted for front-, rear-, or all-wheel-drive layouts, it's capable of underpinning a number of potential products. Toyota is arguably the leader in hybrid technology, and taking lessons learned in the development of the current Prius, the automaker has developed the new Toyota Hybrid System II, or THS-II, for rear-wheel-drive applications. Performance has improved versus the outgoing model, and Toyota says efficiency, especially at high speeds, has been improved. In addition, the system's use in plug-in vehicles has been improved. For the first time, the electric motor will be able to provide direct driving power, whereas before it simply acted as a generator. The new, naturally aspirated 2.5-liter four-cylinder, like the THS-II, has been designed around the TNGA platform. Most notably, the thermal efficiency of the engine has been improved. This means a higher output and improved exhaust and cooling. The new engine, which works in both traditional and hybrid applications, will proliferate through the Toyota and Lexus lineup. Toyota's two new automatic transmissions, like the new engines, are based on the TNGA system. That means a lighter and more compact design relative to similar transmissions. The 10-speed is intended for rear-wheel-drive Lexus products like the GS and LS. The tuning has been adjusted to improve response and smooth out shifts, though it's impossible to say how much it's been improved without getting behind the wheel.

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.

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.
