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

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.

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.

Toyota Hilux successor spotted

The midsize truck segment is suddenly seemingly exploding with new vehicles worldwide, even here in North America. Not only will the Chevrolet Colorado and GMC Canyon be available very soon, Toyota is already testing a replacement for its aging Tacoma and Honda has promised a Ridgeline replacement within the next 18 months. Also, the recently shown Nissan Navara is said to portend the future of our Frontier. Here's some more fresh evidence from Europe of this pickup boom with the next generation of its venerable Hilux in testing.
Thanks to Top Gear and sometimes the evening news, the Hilux has built a reputation of being able to go just about anywhere. According to out spy shooter, this particular pickup was spotted during hot weather testing in southern Europe. Interestingly, a Volkswagen Amarok was along for the ride as a benchmark. Because the VW tends to offer a bit more comfort than the generally utilitarian Hilux, this could indicate Toyota is considering taking the new truck in a slightly comfier, more refined direction.
Compared to the current model, this camouflaged tester sports a narrower front grille and headlights. The hood scoop is also absent here. The lower air dam also receives a more horizontal look, but the more vertical fog light housings provide some contrast. The crazy camouflage pattern makes things hard to discern at the rear, but the taillights appear to be more slender than they on the current model. Unfortunately, mechanical details about the new truck remain a mystery at the moment, but enjoy these spy shots as a preview of one more upcoming pickup.
