Audi details updated 3.0L V6 TDI engine

The brands in the Volkswagen Group have shown that they can develop some of the world's best diesel engines for passenger cars. At the Vienna Motor Symposium taking place May 8 and 9, Audi has an updated one to add to its lineup. It's launching a new version of the 3.0 TDI V6 with better efficiency and more power than the version currently in the US.
The new diesel will be offered in two tunes: 215 horsepower or 268 hp. However, Audi isn't giving away all of the new engine's secrets just yet. It says "depending on model" the mill makes as much as 442.5 pound-feet of torque and gets as much as 13 percent better fuel economy. That likely means the more powerful version gets the twist, and the other one has the better consumption, but we'll have to see.
To compare, the current 3.0 TDI offered in the US produces 240 hp and 428 lb-ft of torque. In the A6, it's rated at 24 miles per gallon city, 38 mpg highway and 29 mpg combined, according to the EPA.

Audi Prologue Concept [w/videos]

What you're looking at here is a preview of Audi's next-gen exterior and interior design. You can't tell, but in these photos, I'm wearing what can only be described as an ultra-white cloth spacesuit. Before opening the large driver's door of the Audi Prologue concept outside of the SLS Hotel in Beverly Hills, Audi requested that I don a super-attractive onesie so as to not let my flannel-covered human flesh touch the untreated leather surfaces of the Prologue's interior. I tied the spacesuit around me just above the waist, let my Converse poke out the footholes, and promised to hold in any sneezes. After all, I was being granted a serious privilege. I was about to drive the multi-million dollar, only-one-in-the-world Prologue that had just stunned crowds at the Los Angeles Auto Show days earlier. This isn't the first time Audi has bravely let the media sample its conceptual wares. In 2010, the German automaker granted us access to its incredibly enticing Quattro concept, probably hoping that the media would rave about the thing enough to convince the higher powers to actually green-light and build it. (We're still waiting on that one, of course.) You could argue that this same logic was applied when allowing me to drive the Prologue – it's no secret that Audi has been dreaming of a range-topping A9, though company officials told me that there is currently no decision on whether or not to produce such a car. But that's not really what the Prologue is about. As its name suggests, what you're looking at here is a preview of Audi's next-generation exterior and interior design, in a fully baked, fully functional package. Suit up, and behold the future. While the Prologue won't necessarily spawn its own production model, its elements will be incorporated on the next A6, A7 and A8. "Timeless but progressive." That's the key takeaway of the Prologue's aesthetic, according to exterior designer Parys Cybulski. The focus here is on beautiful, yet modern, simplicity. A design that looks both contemporary and forward-thinking at the same time, and something that will still look up-to-date in several years' time. After all, while the Prologue won't necessarily spawn its own production model, its elements will be incorporated on the next A6, A7 and A8. Up front, the most prominent feature is, of course, Audi's single-frame grille, seen here with a larger breadth than anything else in the brand's lineup, though its closest resemblance is seen on the new TT.

Audi may add plug-in hybrid A6, A8 and Q7 to range [w/poll]

Audi could be getting even more diverse with its powertrains for the A6, A8 and Q7, moving beyond offering just gas- and diesel-powered models and adding plug-in hybrid variants of the three luxury vehicles. The report comes from Indian Autos Blog, which spoke to Dr. Ulrich Hackenberg, Audi's research and design chief, who confirmed the PHVs.
The next-generation Q7, due in 2015, will be the pioneer for the full-size PHV movement from Audi, although the A3 Sportback E-Tron (shown above) will precede it. The move toward plug-ins by Audi is a big step, as the German marque has stayed quite firmly in the diesel camp, outside of its racing efforts. It's developed a few E-Tron cars over the years, including a version based on the R8, although it wasn't until recently that production of the electric sports car became serious again.
It's believed that this hesitance to really dive into the PHV market is why Audi sacked former research and design boss Wolfgan Dürheimer, with IAB speculating that his approach was too conservative.
