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 bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

Recharge Wrap-up: Air Liquide buys Airgas, Audi automated parking in Boston

Air Liquide will buy US competitor Airgas for $13.4 billion. The Paris-based industrial gases company — also a major producer of hydrogen gas — will pay $143 per share in the acquisition of Airgas. The deal could help Air Liquide surpass German rival Linde as the world's top industrial gases company. "The US is a very attractive gas market, it's the largest industrial gas market worldwide," says Air Liquide CEO Benoit Potier. "It's the fastest growing market among advanced economies."

Expected to be worth up to $35 million, the funding will focus particularly on the research, development and demonstration of technology for light duty passenger vehicles with the goal of reducing greenhouse gas emissions and petroleum consumption. This includes hydrogen production, delivery and storage, as well as fuel cell technologies, manufacturing and analysis. The DOE expects to issue the Funding Opportunity Announcement around December 10. Read more at Green Car Congress. Audi will bring network infrastructure and automated parking to the Boston area. In an agreement with the city of Somerville, Massachusetts, Audi will work to improve traffic flow and increase the efficiency of space used for parking. As the city continues to develop, Audi's automated parking project will help decrease the amount of land needed to park cars, and the extra space can be used for more important real estate. Also, an intelligent traffic management project connecting cars to traffic lights can help reduce congestion. Read more in the press release below.

Audi CEO Rupert Stadler and Mayor Joseph A. Curtatone signed a Memorandum of Understanding in the context of the Smart City Expo World Congress in Barcelona. They agreed to develop an urban strategy for Somerville, applying technologies for swarm intelligence or automated parking, and networking cars with traffic lights.
