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.

New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

TT Offroad Concept shows Audi's design icon isn't afraid to play dirty

We'll step right out and say we like the TT Offroad Concept, but there's something that's just a bit too... familiar about it. Yes, this yellow five-door looks like a not-so-distant relative of the Allroad Shooting Brake Concept that debuted at the 2014 Detroit Auto Show earlier this year. So, we've seen the production TT, a super-light, high-performance model and now we're seeing a crossover. Does any of this sound familiar? Considering the Detroit concept earned an editors' choice award for that show, you can imagine how we feel about the strikingly similar TT Offroad, which is debuting at the Beijing Motor Show.
The two concepts share a propulsion system - a high-performance version of Audi's E-Tron plug-in-hybrid drivetrain. Total system output sits at 408 horsepower, thanks to a 2.0-liter, turbocharged four-cylinder and a 40-kilowatt electric motor in front and an 85-kW motor on the rear axle, for all-wheel drive. 62 miles per hour arrives in 5.2 seconds, while the TT Offroad is limited to 155 mph. Fuel economy is impressive, with a claimed 123.8 US miles per gallon on the European cycle.
The most obvious different between these two, then, are their looks. The TT looks a bit tougher, thanks to its larger 21-inch wheels and narrower headlights, but its more conventional belt and roofline give it more of an Audi Q3's look. Out back, a slightly restyled bumper is the sole differentiator between the two vehicles.
