Audi AI: an important step forward in autonomy

Those who have visions of reading a book or watching a movie while sitting in traffic, as you might do on an airplane, are closer than ever to reaching their own version of automotive nirvana. We're still not there, but Audi's latest A8 brings us right up to the precipice of actual autonomy that you can program to self-park in your garage. Audi says its new A8 will be the first vehicle to deliver Level 3 autonomy. That means the driver can take his or her hands off the steering wheel and stop paying attention, at least when a specific set of circumstances are met. First, Audi's AI traffic jam pilot only works at speeds of up to 37.3 miles per hour. In other words, it's meant for those times where you're sitting in traffic. Audi believes that the first commercially available self-driving applications will be relied on for circumstances when a driver's time is better spent elsewhere, like when you're in bumper-to-bumper traffic on the freeway. Second, that freeway has to be a divided highway with a physical barrier from oncoming vehicles. A large swath of grass would work, as would a concrete wall. The new A8 uses radar, a front camera, ultrasonic sensors, and a laser scanner – the first in a production vehicle – to scan its surroundings. These various images are compiled by a central driver assistance controller that Audi calls zFAS. We'd have gone with Zaphod Beeblebrox, but nobody asked. Third, Audi needs the approval and cooperation of the various governments and authorities in which it sells the A8. "The statutory framework will need to be clarified in each individual market, along with the country-specific definition of the application and testing of the system," says Audi. Where does that leave the US? Audi isn't yet sure, but discussions are apparently under way. We're not exactly holding our breath. If all of those key circumstances are met, Audi's artificial intelligence system can be activated using the AI button on the center console. Audi will accept all legal responsibility when the car is driving itself. Starting, steering, acceleration, and braking are all taken over by the car, and the driver is free to perform other tasks. Theoretically, at least, because nobody outside of Audi has actually given the AI tech a spin. "As soon as the system reaches its limits," says Audi, it will hand driving duties back off to the driver.

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.

2014 Audi Q5 TDI

I've struggled with diesel technology. It's not that I have a problem with it or dislike it, but rather that I don't particularly understand what stops its wider-spread adoption. Sure, memories of rust-prone, smoky, sluggish and uneconomical Oldsmobile diesels aren't exactly easy to erase from the collective memory of the North American motoring public, but I'd think that a few years into the latest crop of clean diesels, there'd be wider adoption - or at least consumer consideration - by now.
Part of the issue is the still limited number of segments that diesels are available in. The Volkswagen Golf/Jetta TDI is finally getting a challenger in the form of the Chevrolet Cruze Diesel, and the BMW 328d is bringing something new to the entry-level sports sedan, but there are still a huge group of segments where diesel-power has no representation.
The small, luxury crossover realm is not one of those. It has the Mercedes-Benz GLK250 Bluetec, a stylish crossover with a silky-smooth 2.1-liter, turbodiesel four-cylinder that can return the kind of fuel economy that makes people take notice. And while the GLK250 is quite good, economy will only spread the diesel's appeal so far. People need to experience the seat-flattening torque that these mills can produce, and for that, we most humbly recommend the new 2014 Audi Q5 TDI.
