Toyota promises a next-generation Land Cruiser is on its way

On sale since the 2008 model year and facelifted twice in the interim, the Toyota Land Cruiser has lately begun rolling out the special editions. Last year we got the 2019 Lexus LX Inspiration, this year we got the 2020 Land Cruiser Heritage Edition. This likely means a changing of the model guard is close, the 300-Series Land Cruiser on the horizon to replace the current 200-Series. When Motor Authority asked Toyota SVP Bill Fay about the U.S. getting the next generation, Fay replied, "We are fully committed to the Land Cruiser for the foreseeable future." The reason for the question could have been Land Cruiser sales figures for the past 14 years, when the model never cleared 5,000 units. The swankier Lexus LX sibling sells in greater numbers, but even lumping the two trucks, they've crested 10,000 sales just twice since 2005. On top of that, two of the largest regional markets for the Land Cruiser are Australia and the Middle East, which have different regulatory regimes, and the 2019 Highlander has a three-row option. Why carry on with the Land Cruiser here? Fay told MA the body-on-frame bruiser is a "heritage vehicle," a staple in the U.S. lineup since 1958. But the Cruiser that comes next is expected to LS-ify its powertrain formula, which means getting rid of V8s for V6s. The 5.7-liter V8 with 381 horsepower, 401 pound-feet of torque, and an EPA rating of 15 miles per gallon combined should go away. The 3.5-liter twin-turbo V6 in the Lexus LS 500 gets the nod to take its place, as the Land Cruiser make concessions to fuel economy and emissions standards. A poster on a forum said it's possible that a Dynamic Force version of that engine might appear. As is, that engine makes 416 hp and 442 lb-ft in the luxury sedan and is mated to a 10-speed automatic, the same transmission said to replace the current eight-speed in the Land Cruiser. Automotive mediums predict a hybrid Cruiser, too, potentially with the same 3.5-liter naturally aspirated V6 and 10-speed auto in the LS hybrid, putting out 354 combined horsepower in the sedan. Because there are so many Land Cruiser versions around the world, it's impossible to say whether V8 options will die globally. Land Cruiser fans, either through desperation or good intel, say that isn't the case.

Vehicles awarded IIHS Top Safety Pick awards skyrockets for 2015 [w/video]

By practically every measure, passenger vehicles in the US are continuing to get safer. With the year rapidly coming to an end, the Insurance Institute for Highway Safety is releasing its annual list tallying of the scores for the latest vehicles to see how they compare to last year. Judging by the agency's evaluations, the numbers look quite positive. According to the institute, 71 vehicles earned either the Top Safety Pick or Top Safety Pick+ rating so far in its testing for 2015. Among the latest winners, there have been 33 TSP+ awards and 38 TSP medalists. That's a healthy increase over the 22 TSP+ and 17 TSP grades in 2014. The figures appear even more impressive when you consider that it keeps getting harder to earn the + designation. In the latest round of testing, a vehicle must offer some form of front crash prevention automatic braking to get the mark. Previously, just a warning to drivers was necessary. This list also illustrates the ways that automakers adapt to new testing procedures. In 2013 there were 117 TSP ratings and 13 TSP+ awards. Then, the IIHS mandated that to be a safety pick, a model had to score Good in the institute's four crash tests, plus a Good or Acceptable in the small overlap front test. That brought a plunge in 2014 to just 17 TSP grades. With the numbers climbing again, companies apparently have deciphered how to perform better. Some brands especially stood out on this year's list. The IIHS praised Volvo, Mercedes-Benz and Acura for offering standard front crash prevention systems on some models. Subaru received at least one of the awards for all seven of its models. Toyota also had seven, and the Honda brand did too – though the institute counts the two- and four-door versions of the Civic and Accord separately. Check out the full announcement below and a video about this year's winners. The full list can be viewed, here. Safety gains ground: More vehicles earn top honors from IIHS The number of vehicles earning either of the Institute's two awards has jumped to 71 from 39 this time last year, giving consumers more choices for optimum protection in crashes. The number of winners in the top tier - TOP SAFETY PICK+ - has increased by 11 for 2015, despite a tougher standard for front crash prevention. "This is the third year in a row that we are giving automakers a tougher challenge to meet," says IIHS President Adrian Lund.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy. Read more in the press release below. Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
