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.

Audi tests new kind of car sharing, lets you buy cars with buddies [w/video]

Car sharing services like ZipCar, Car2Go and others offer people in cities the chance to have a vehicle without dealing with the hassles of parking or maintenance, while also eliminating traffic. However, many individuals are turned off by the idea of splitting a car with an entire metropolis or would prefer to have a specific model at their disposal. For these unsatisfied souls, Audi has a new arrangement in Stockholm, Sweden, called Audi Unite that might be just the ticket. The setup is basically a small-scale car sharing service. Up to five people agree to share any of Audi's models for a year or two – even an R8 if they are so inclined. Each user has a special Bluetooth key fob that identifies them to the vehicle, and a smartphone app allows operators to schedule time with the car. Each person is then billed monthly according to his or her use. Audi thinks it might work best with friends, colleagues or neighbors, but the company can also play matchmaker for clients, if necessary. "In the beginning, our biggest fear was what if two people want to go somewhere at the same time-what happens then?" said Clemens Weisshaar, one of the founders of design firm Kram/Weisshaar that helped develop the idea, to Fast Company. "Interestingly, it never happened." They chose Stockholm because the city was tech-savvy, and there is a tradition of sharing there. Prices for Audi Unite seem fairly reasonable for each user. According to the service's website, if four people use an A3 Sportback for two years with a 20,000-kilometer (12,247-mile) driving limit, they would pay an average of 2,091 Swedish krona ($277) each per month. For an extra 365 krona (about $50) per person each month, they can add a package that includes vehicle pickup and delivery for monthly interior and exterior cleaning, winter tire exchanges and necessary servicing. After Stockholm, Audi plans to try Unite in other Swedish cities before launching the program in additional countries, according to Fast Company.
