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 finds CO2 'irregularities' for 800k vehicles

The latest issue for Volkswagen affects another 800,000 vehicles, and this time its for irregularities in CO2 emissions certifications. VW estimates this issue could cost the company $2.2 billion to fix. The company officially makes no specific mention of which engines are covered, the models they are in, or even where they are located. VW discovered the situation during its ongoing internal investigation, and, according to the automaker, "it was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process." Most of the affected vehicles are diesels, and the company is now reaching out to "the responsible type approval agencies" to figure out the next step. While VW isn't officially confirming which models and engines are involved, Automotive News reports that it affects some 2012 and later VW, Audi, Seat, and Skoda models with the company's 1.4-, 1.6-, and 2.0-liter diesel engines, as well as the 1.4-liter ACT gasoline engine. The issue mainly affects vehicles sold in Europe. "The Board of Management of Volkswagen AG deeply regrets this situation and wishes to underscore its determination to systematically continue along the present path of clarification and transparency," CEO Matthias Muller said in the announcement. Volkswagen Group of America spokesperson Jeannine Ginivan was able to provide some further clarification to Autoblog. "This is not related to US-certified vehicles," she said. Clarification moving forward: internal investigations at Volkswagen identify irregularities in CO2 levels Matthias Muller: "Relentless and comprehensive clarification is our only alternative." Around 800,000 Group vehicles could be affected Initial estimate puts economic risks at approximately 2 billion euros The Volkswagen Group is moving forward with the clarification of the diesel issue: during the course of internal investigations irregularities were found when determining type approval CO2 levels. Based on present knowledge around 800,000 vehicles from the Volkswagen Group could be affected. An initial estimate puts the economic risks at approximately two billion euros. The Board of Management of Volkswagen AG will immediately start a dialog with the responsible type approval agencies regarding the consequences of these findings. This should lead to a reliable assessment of the legal, and the subsequent economic consequences of this not yet fully explained issue.

2019 Volvo V60 vs. wagon competitors: How they compare on paper

The next-gen Volvo V60 was finally revealed this week. The outgoing model has been on sale since 2011, getting a few minor updates along the way. The new model is based off Volvo's Scalable Platform Architecture that underpins other models like the XC90 and XC60 crossovers and V90 wagon. The V60 will launch with two engines, with a powerful hybrid coming sometime down the line. Since the last V60 hit the market, Audi, Buick and BMW have all released their own flavor of wagon. Like Volvo, BMW sells a traditional sedan-based model. Audi and Buick's wagons are both high-riding models with some very slight off-road pretense, much like Volvo's Cross Country models. We don't have details on the upcoming V60 Cross Country, but, even when accounting for ground clearance, the V60, BMW 3 Series Sport Wagon, A4 Allroad and Buick Regal TourX have a lot of overlap. Check out the specs breakdown below. Discover and compare other wagons and crossovers with our Car Finder and Compare tools. Engines, transmissions and drivetrains Out of the four wagons, the new V60 is the only one that offers two-wheel drive and a hybrid variant. The base V60 T5 uses a 250-horsepower turbocharged 2.0-liter inline four and sends power to the front wheels. Stepping up to the V60 T6 nets buyers an additional 66 horsepower thanks to a twincharged — supercharged and turbocharged — 2.0-liter and all-wheel drive. A T8 model that uses a 390-horsepower plug-in hybrid powertrain will be available soon. All V60s use an eight-speed automatic. The Audi, BMW and Buick are all powered by 2.0-liter turbocharged inline-fours. Additionally, the 3 Series has a 2.0-liter turbo diesel. All three wagons have standard all-wheel drive. The BMW and Buick use an eight-speed automatic, while the Audi sends power through a seven-speed dual-clutch transmission. As base engines go, there's a four-horsepower difference between the most and least powerful models, though the Buick wins out on torque. The V60 T6 matches the Regal TourX's torque figure and trounces every competitor's horsepower rating. The V60 T8 packs more power and torque than any of the competition. Cargo and interior space The outgoing V60 was on the small side for a wagon. This new model rectifies that a bit, though its 48.2 cubic-feet of cargo space with the second-row folded is still substantially smaller than the competition.
