Recharge Wrap-up: Nissan "religious" about zero-emissions, Tesla crashes at dealership, Formula E on-board video

Nissan is pretty darn serious about being king of the EV industry. Just see what Chief Planning Officer Andy Palmer has to say at the launch of the e-NV200: "When it comes to zero emissions, we're absolutely religious. We'll be the absolute, No. 1 leader in zero emissions. No doubt. That's our positioning." Bold words, to be sure. Toyota, on the other hand, ended its collaboration with Tesla (whom Nissan mustn't forget about in its quest to reign supreme in the EV world) to build the RAV4 EV, and will focus instead on hybrids and testing the waters with hydrogen cars. Says Jim Lentz, CEO of Toyota North America, "I would rather invest my dollars in fuel cell development than in another 2,500 EVs." Read more at Automotive News or Autoweek. To celebrate 25 years of TDI technology, Audi is releasing the A7 Sportback 3.0 TDI Competition special edition in Europe. The Competition uses Audi's biturbocharged, 3.0-liter diesel engine boosted to 326 horsepower, giving the car a 0-62 time of 5.1 seconds. It comes with the S line sport package and is offered in four exterior colors: Daytona Gray, Misano Red, Nardo Gray and Sepang Blue. The interior is black leather, with the option of Misano Red or Agate Gray contrast stitching. The Competition edition will go on sale in August starting at ˆ72,000 (about $97,700). Audi's first Turbocharged Direct Injection engine debuted at the 1989 Frankfurt Motor Show in the Audi 100 2.5 TDI. See the press release down below for more details. There was another Tesla Model S crash recently, this one at the Tesla Store. The driver apparently crashed the freshly purchased car into the Tesla sign before even making it off the lot. According to Reddit user s1lentway, who was at the Tesla Store in Fremont, California when it happened, "We believe this is someone who just got their car. They must have been driving it for less than a minute and lost control, crashing right into the sign missing the showroom glass windows only by a few inches." Wrecked Exotics suggests the driver hit the accelerator instead of the brake pedal. Probably the best comment in the Reddit post: "Edison strikes again." See the original post at Reddit for more corny jokes, speculation and similar stories from other users. Take a lap in a Formula E racecar. The video below offers up the sights and sounds of a hot, wet lap in the open-cockpit, all-electric Spark-Renault SRT_01E.

Popular Science magazine's Best Of What's New 2012 all ate up with cars

Popular Science has named the winners in its Best of What's New awards, the victors coming in the categories of aerospace, automotive, engineering, entertainment, gadgets, green, hardware, health, home, recreation, security and software. The automotive category did not go wanting for lauded advancements:
Tesla Model S: the Grand Award winner for being "the standard by which all future electric vehicles will be measured."
BMW 328i: it's 2.0-liter turbocharged four-cylinder gets called out for being more powerful and frugal than the six-cylinder it replaces.

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.
