Toyota reveals updated TS040 Hybrid LMP1 for 2015 [w/videos]

Toyota has yet to defeat Audi at Le Mans. In fact, nobody has in the past fifteen years except for Peugeot (which won in 2009) and Audi's own sister company Bentley (which took the checkered flag in 2003). But Toyota did win the broader FIA World Endurance Championship last season, beating its German rivals in five out of eight rounds. That means the Japanese automaker is returning to top-level endurance racing this season as the reigning champions, and this is the car with which it aims to defend its title. The 2015 Toyota TS040 Hybrid is closely based on last year's winning version, but has been updated to comply with the latest tweaks to the regulations. A new crash structure meant redesigning the front end, the aerodynamics package has been thoroughly revised, the suspension reconfigured and extra weight has been cut. All told, Toyota says it redesigned 80 percent of the parts on board. Each team running a hybrid prototype has an array of choices over what combination of internal-combustion and electric boost it will run, but Toyota opted to stay in the 6MJ category for 2015, the electric boost working in tandem with the 3.7-liter V8 to give the TS040 a combined output of over 1,000 horsepower. The team also developed two aero kits: one for high-speed circuits like La Sarthe that warrant reduced drag, and the other for tighter tracks requiring increased downforce. The revised TS040 has already undergone over 15,000 miles of testing in southern Europe over the winter. But the real test will come at Silverstone in two weeks for the opening round of the 2015 championship when it will have to fend off a two-pronged German assault from both Audi and Porsche ahead of the headline event at Le Mans in June. We'll be watching to see who comes out on top this year, but for now you can watch footage of Toyota's latest in the pair of videos below. This content is hosted by a third party.

Mar. 26, 2015 A New Era for the World Champions Toyota Racing enters the 2015 World Endurance Championship ready to start a new era with the defence of its two titles. Toyota became the first Japanese company to win the World Championship during a very successful 2014 season, which saw Anthony Davidson and Sebastien Buemi also win the drivers' title.

Even Ferrari swept up in latest Takata recall expansion

The scope of Takata's deadly airbag problems continues to widen. Eight manufacturers announced recalls Friday that affect more than 12 million vehicles, according to documents filed with federal regulators. The automakers include Honda, which is recalling 4.5 million units, Fiat Chrysler with 4.3 million, Toyota with 1.65 million, and Subaru, which is recalling almost 400,000. Some of these cars include the Saab 9-2x and Pontiac Vibe that Toyota and Subaru made for General Motors. Mazda will recall 730,000 vehicles and Nissan has 400,000 affected units. The smallest numbers were posted by Mitsubishi, with 38,000 Lancers manufactured from 2006 to 2007, and as a noteworthy high-end manufacturer, Ferrari is calling back 2,800 vehicles. These are all US-market cars. Beyond America, the Japanese Transport Ministry has announced seven million additional vehicles will be recalled, which means 19.6 million vehicles across the globe are affected by recalls announced. The defects have been traced to an insufficiently manufactured airbag inflator, which lacks a drying agent that would prevent the inflators from deteriorating over time. Thirteen deaths have been linked to the faulty airbags, which have become unstable and are prone to exploding and showering vehicle occupants with lethal amounts of metal shrapnel. A private equity firm, KKR & Co., has been named in a possible buyout of the struggling Takata.

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.
