Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

The 2013 Rolex 24-hour race at Daytona comes down to the last hour [spoilers, w/video]

It took 24 hours to run the race, but it was the last one was stuffed with the high action as four cars were still trying to figure out how to gain victory on the track and in the pits. Along with the obligatory crashes, spins, mechanical issues and retirements had come numerous penalties, a double-digit number of full-course yellows and two hours of fog that turned early Sunday morning into a stretch of parade laps.
The final hour would make up for the morning - drivers who might have been happy just to get on the podium had a shot at victory as the end of the race approached, and that turned into a few gambles that paid off, and at least one that didn't...

Recharge Wrap-up: New and old Audis get greener, as does US electricity

Audi has made environmental improvements to the its TT while boosting performance. The new TT sees an 11-percent reduction in emissions, and up to 14 percent more power. Audi says that each TT will save around 5.5 metric tons of greenhouse gas emissions over its lifecycle. Additionally, the TT's manufacturing process has been cleaned up a bit, reducing emissions by about nine percent. Read more in the press release, below, or see Audi's lifecycle assessment here. Speaking of greening up Audis, Al Swackhammer of Washington converted his 1960 Audi DKW 1000S to run on electric power. Swackhammer first fell in love with the Audi Ur-Quattro, became an enthusiast of Audi and Volkswagen cars, and has owned nothing else ever since. With his DKW, he combined his passion for the classic car with his responsibility to the environment. "I am pleased that I did this project," says the happy owner, "and I enjoy driving it very dearly." Meet the man and his beloved electric Audi DKW in the video below. Toyota has chosen a sustainable design firm, Corgan, as the lead architect for its new North American headquarters. The new campus will be built in Plano, TX, and will be the workplace of about 4,000 Toyota employees. Corgan, who has already done 47 LEED certified projects, is already designing a temporary office for the site while it finishes the project. Toyota expects to begin working from the site in late 2016 or early 2017. Learn more in the press release below. In July, all new electrical generating capacity in the US came from renewable sources. The Federal Energy Regulatory Commission's Office of Energy Projects' newest "Energy Infrastructure Update" report says new electric generation put into service last month came from wind (379 megawatts), solar (21 megawatts) and hydro (5 megawatts). So far this year, 53 percent of new energy generation capacity has come from various renewable sources, and none from coal or nuclear. Currently, renewable energy accounts for 16.3 percent of the US electric generation capacity, providing about 14 percent of actual electricity.
