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.

Don't buy that crossover! Buy a cladded wagon instead!

If you're looking to buy a car soon, and you're like most Americans, there's a strong chance you're considering buying a crossover SUV. That's what people want nowadays. People like the tough, tall exterior that suggests adventure and preparedness, they like the high seating position, they like the all wheel drive many have and they like the practicality. Because of this, crossovers have rapidly supplanted typical cars such as sedans, wagons, and more as the most popular vehicles in the country. But they're compromised, too. They're often heavy, thirsty, and expensive compared with more conventional cars. The good news is, there's an alternative, a happy medium between the straight crossover and the traditional car. They're lifted wagons, and they're the best crossover SUVs around. And for those who may not know what we're talking about, we're talking about cars and wagons that have been given a suspension lift for more ground clearance and a higher ride height, and often have all wheel drive standard or optional. They also usually have chunky plastic body cladding to make them look tough and durable. Examples include the Subaru Crosstrek, Audi A4 Allroad, Buick Regal TourX, and Volkswagen Golf Alltrack, among others. Because of the suspension and body modifications, these vehicles fit the trendy crossover mold quite well. And in the case of long-running nameplates such as the Subaru Outback and Volvo Cross Country models, they even have some heritage as outdoorsy machines. They also provide the higher driving position that crossover buyers love. And in some cases, such as with the Golf Alltrack, we've learned they offer better ride quality than their road-oriented siblings.

For instance, the aforementioned Golf Alltrack still drives mostly like a Golf, which is to say, it's nimble, feels peppy, and is easy to maneuver because of its relatively small size. We can't really say the same for the Tiguan, which feels generally more sluggish and uninteresting than the Alltrack. And we mention Volkswagen's compact crossover because it starts at nearly the same price as the Alltrack. Some of the difference in giddy-up can be explained by weight. Normal crossovers can be fairly portly, while these lifted wagons are notably lighter.
