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.

J.D. Power study sees new car dependability problems increase for first time since 1998

For the first time since 1998, J.D. Power and Associates says its data shows that the average number of problems per 100 cars has increased. The finding is the result of the firm's much-touted annual Vehicle Dependability Study, which charts incidents of problems in new vehicle purchases over three years from 41,000 respondents.
Looking at first-owner cars from the 2011 model year, the study found an average of 133 problems per 100 cars (PP100, for short), up 6 percent from 126 PP100 in last year's study, which covered 2010 model-year vehicles. Disturbingly, the bulk of the increase is being attributed to engine and transmission problems, with a 6 PP100 boost.
Interestingly, JDP notes that "the decline in quality is particularly acute for vehicles with four-cylinder engines, where problem levels increase by nearly 10 PP100." Its findings also noticed that large diesel engines also tended to be more problematic than most five- and six-cylinder engines.

2015 Lexus LS gets tiny tweaks to try to keep up in LA

The 2015 model-year updates for the LS are certainly minor, but at least Lexus isn't letting its flagship sedan languish completely. The biggest change for the revised model is an improved infotainment system with an updated navigation and dynamic guidelines for the backup camera. Lexus' Enform App Suite also allows owners to remotely control some of the vehicle's functions, including the door locks, ignition and climate control settings. Among the litany of incredibly small tweaks, the dome lights now use LEDs, and the F Sport model that includes features like a sport-tuned air suspension and 19-inch forged wheels gets an added badge at the rear. The changes have increased the turning circle by 3.9 inches for models with the standard suspension and 18-inch wheels. All of the changes are definitely minor, but hopefully they'll sustain the posh motor until its next iteration is ready. 2015 Lexus LS Shows Why This Luxury Flagship Became A Luxury Legend - New Multimedia System for 2015 - Lexus Enform App Suite Upgraded - Upgraded Backup Camera With Dynamic Gridlines - F SPORT Model With Special Suspension, 19-inch Wheels, Brembo Brakes October 16, 2014 History seems to be repeating itself. The Lexus LS upended the luxury segment a quarter-century ago, and one reason was that it made a powerful V8 engine standard when it was a very expensive extra-cost option in some European models and not even available in others. Just change the year to 2015, and the situation seems to be replaying. A supremely smooth, standard 386-horsepower 4.6-liter V8 teamed with an eight-speed automatic transmission is only one facet of the 2015 Lexus LS 460, though undeniably, it's the one whose benefit you feel quite strongly during a road test. Nearly silent acceleration remains a hallmark aspect of driving a Lexus LS, which also offers the option of a more engaging driving experience with the F SPORT Package. A wide range of model choices also make the Lexus LS a standout. The LS 460 comes in regular and long-wheelbase versions, each with the further choice of rear-wheel drive or all-weather drive (360 hp with AWD). The ultimate Lexus flagship sedan remains the LS 600h L hybrid with 438 total system horsepower from a 5-liter V8 paired with an electric motor and all-weather drive. New for 2015, the LS gains a new multimedia system. The multimedia system, accessed through the navigation screen, provides a multitude of capabilities.
