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.

Volkswagen profit jumps as it warns of a cooling auto market

FRANKFURT, Germany — Volkswagen says its profits jumped 44% in the third quarter thanks to a more profitable mix of vehicles in its lineup but warned that global car markets are slowing more than expected and lowered its forecast for annual sales. After-tax profit rose to $4.42 billion (3.98 billion euros) as revenues rose 11% to $68.27 billion (61.42 billion euros). The sales margin of 7.8% exceeded the goal of 6.5-7.5% as vehicles bringing higher profits took a larger share of sales. The Wolfsburg-based automaker pointed to the headwinds facing the industry by saying that it expects "vehicle markets will contract faster than previously anticipated in many regions of the world." It said sales would be "on a level" with last year's record of 10.8 million vehicles. Previously it had expected a slight increase. The company said its profits would be in the lower end of its forecast range. Global automakers are facing a slowdown in sales amid disputes over trade and from pressure in the European Union and China to develop and sell low-emission vehicles that require heavy investment in new technology. Ford and Renault have issued profit warnings in recent days, while Daimler, maker of Mercedes-Benz luxury cars, lost money in the second quarter and is expected to outline a cost-cutting strategy for investors on Nov. 14. Volkswagen is leading the push into electric vehicles in Europe by launching its ID.3 battery-powered compact car at prices it says will make zero local emission vehicles a mass phenomenon. The company was able to increase earnings in the quarter despite an 18% rise in spending on research and development.

Xcar weighs in on the five best-sounding modern cars

Getting behind the wheel of a well-balanced vehicle can be a wonderfully visceral experience, thanks to the combined feeling of things like the weight of the steering, the bite of the brakes, and, of course, the roar of the engine. Unfortunately, many of the sensations of driving require actually being in the driver's seat to understand them, but thankfully the intoxicating noise of a beautifully tuned internal combustion engine can be shared with everyone. In a new video, Xcar shares their opinion on the five best-sounding modern performance cars. The list is a symphony of horsepower. As opposed to keeping all of the vehicles brand new, Xcar actually picks a few that are recently off the market. They're all definitely champs, though. While the list itself is well stocked, you might be able to argue with the specific order, and it would be nice to hear a few participants from outside of Europe for a collection like this one, too. No matter. Every listener is sure to find something they like in the bunch, though. Turn up the volume and enjoy.
