We demo Audi's Traffic Jam Assistant tech on the road [w/video]

The closer automotive technology comes to making good on the promise of fully driverless vehicles, the better we see just what difficult work reaching that ultimate goal will become. That's because, unlike so many other in-car technologies that need only integration into a vehicle, truly autonomous cars will also insist on involvement with the surrounding environment, fellow motorists, infrastructure in cities and other communities and making it all work without exposing automakers to law-breaking or tremendous possible litigation. Clearly that isn't all about to happen in one go.
At CES in 2012, Audi told us about a debuting technology that would mark a significant step along the path towards self-driving cars: Traffic Jam Assistant. This year, the German automaker invited us out to Las Vegas to see the jam-busting technology in action, on a relatively busy freeway.
The Traffic Jam Assistant (we're pretty sure that name is still in Beta) promises to relieve drivers from the tedium of slow-moving freeways by taking care of braking, acceleration and staying inside of the lane - all with no input from the human behind the wheel. While still a fair step from truly autonomous driving, the goal here is to give a commuter some respite from the mechanical, time-wasting traffic jam paradigm, potentially opening up a space for productivity in the process. (Audi can't come right out and say that TJA will allow you to use your cell phone in traffic, as that's still against the law in many places, but something like that is clearly on the radar... er... LiDAR.)

Audi A3 Cabriolet leaked ahead of Frankfurt

Leaked images of the new Audi A3 Cabriolet have emerged ahead of the compact droptop's debut at next week's Frankfurt Motor Show. Audi has sold a convertible A3 in Europe since 2008, although that car has never made it to the US market. Still, with Audi already bringing an A3 and S3 sedan across the pond, there's hope for this small convertible to arrive here.
The looks of the A3 Cabrio aren't a huge departure from the A3 sedan, besides the obvious deletion of rear doors. We can't tell from the images shown, but considering Audi still hasn't brought a folding hardtop to market, we don't imagine it'll start with an entry level model like the A3. Expect a fast-folding canvas roof, much like the A5 Cabriolet.
From the leaked images, we can see TFSI and Quattro badges on this A3. It seems natural that the Cabrio will sport the same range of four-cylinder engines as the sedan - a 2.0-liter TDI, a 1.4-liter turbo and a 2.0-liter turbo. Of course, we'll have much more on the new A3 Cabrio when it makes its debut in Frankfurt.

Spy video shows Audi RS4 Avant twin-turbo V6 lapping the Nurburgring

Nurburgring testing season is in full swing, and Audi took some of its newest upcoming models for a spin. That means our first listen to Ingolstadt's new, turbocharged RS engine under the hood of the RS4. Based off the updated A4, the new RS4 Avant is a return to the performance variant's roots. The original RS4 (and early versions of the S4) used twin-turbo V6 power, although more recent models stuffed the beloved 4.2-liter V8 under the hood. The turbo engine in the new model is also rumored to find its way into the back of the R8 supercar. We don't know horsepower figures yet, but with 450 horsepower as the benchmark from the last RS4 we expect big numbers from the six-cylinder. The new engine might be just as powerful as the old V8, but as you'll see in the video, it's missing the phenomenal growl that the 4.2-liter made as it revved to the sky. This new car is quiet, especially compared to the ear-tingling five-cylinder note of the TT RS testing alongside the wagon. A quiet performance car is fine if you like stealth, but with its flared wheel arches, oval exhausts, and big wheels, the RS4 is a car that's anything but subtle.
