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.

2015 Audi Q3 headed for Detroit before hitting US showrooms this fall

The market for small premium crossover vehicles continues to grow in popularity here in the US, and Audi is finally ready to get in on the action. Going up against competitors like the BMW X1, Land Rover Range Rover Evoque and soon-to-arrive Mercedes GLA-Class, Audi will unveil a US-spec version of the 2015 Q3 at the Detroit Auto Show next week. And in what we can only assume is an amusing coincidence, the Q3 will go on sale during Q3 of this year.
As we reported back in October, it appears that our Q3 will boast a slightly taller ride height than its European counterpart, but Audi isn't releasing too much information about the crossover just yet. What we know for sure is that it will be powered by Audi's well-liked 2.0-liter turbocharged TFSI inline-four producing 200 horsepower and 207 pound-feet of torque. A six-speed automatic transmission and front-wheel drive will come standard, while Audi's Quattro all-wheel-drive system will be optional.
Visually, the 2015 Q3 shown here has a different front fascia design than its European counterpart, but it's not immediately clear if this is exclusive to the US model or if it will be a new element for Q3 in all markets. We don't expect pricing to be announced until closer to its on-sale date, but the Q3 will definitely be stuffed with content, even in base form. Audi has already confirmed such niceties as a panoramic moonroof, Xenon headlights and heated leather seats. Delivering a good amount of practicality for its size, the Q3 will provide a maximum cargo capacity of up to 48.2 cubic feet and 16.2 cu-ft with the rear seats in place.

Bentley doubles down on diesels with a triple-charged Bentayga

Volkswagen Group isn't totally giving up on diesels. While its flagship VW brand is clearly tarnished, the ultra-luxury Bentley division just revealed plans for its first oil-burner, a triple-charged 4.0-liter V8 that produces 429 horsepower and 664 pound-feet of torque. If the powertrain sounds familiar, that's because it's the same one found in the Audi SQ7 TDI. It's a clever system capable of giving what Bentley claims as the world's fastest diesel SUV a top speed of 168 miles per hour and a zero-to-62 mph time of 4.8 seconds. The SQ7 TDI can get to 62 mph in the same time, but is electronically limited to 155 mph, because it wouldn't make sense if the cheaper SUV could outperform the much more expensive one. The Bentayga also emits the lowest CO2 output of any Bentley and has a range of over 621 miles on one tank. Despite having a curb weight of 5,269 pounds, Bentley claims the Bentayga can get a combined rating of 35.8 mpg on the European cycle. The Bentayga Diesel may not be as powerful or as fast as the W12-powered model, but it's a lot more fuel efficient as the latter achieves a combined rating of 21.6 mpg on the European cycle. Other than the new engine, the Bentayga diesel is nearly identical to its gasoline-powered twin except for some discreet "V8 Diesel" badges on the front doors, a new exhaust outlet design, and a black grille. A Bentley spokesperson confirmed that the Bentayga diesel would not be sold in the US. And since Bentley won't be at this year's Paris Motor Show, don't get your hopes up on spotting the vehicle there. The diesel-powered SUV will go on sale in Europe early next year, which will be followed by its release in Russia, South Africa, Australia, New Zealand, and Taiwan. Pricing for the SUV has not been announced yet.
