Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.

Porsche bringing Macan S Diesel to US instead of 4-cylinder [w/poll]

When Porsche unveiled the new Macan at the LA Auto Show, it announced two powerplants for the US market, both of them twin-turbo V6s: the Macan S equipped with 340 horsepower from its 3.0-liter engine, and the Macan Turbo with 400 horses from 3.6 liters. But those aren't the only engines Porsche will offer in its new compact crossover. Porsche is also offering the Macan S Diesel overseas with 258 hp, and reports have since indicated that a pair of four-cylinder models on their way: a 2.0-liter turbo four with 280 hp and four-pot turbodiesel of the same capacity with an as-yet undisclosed output.
Now Car and Driver is reporting that while those four-cylinder engines won't be making the transatlantic voyage to our shores, Porsche will offer the aforementioned Macan S Diesel in North America beginning in early 2015, nearly a year after the gas V6 versions arrive.
The 3.0-liter turbodiesel V6 is based on the same engine found in the Cayenne Diesel and the Audi Q5 TDI on which the Macan is based. Of course, its 248 hp is substantially less than the 340 ponies in the Macan S, but its 413 pound-feet of torque outshines not only the 339 lb-ft in the Macan S but also the 406 lb-ft in the Macan Turbo. Acceleration times, however, suggest the Macan S Diesel is still slower, with a 6.3-second run to 62 mph than neither the Macan S (5.4 sec) or Macan Turbo (4.8). The good news is that the Macan S Diesel is tipped to undercut the price of both, dropping the oil-burning crossover's MSRP below that of the $49,900 starting price for the Macan S and the $49,600 for the base Cayenne. If that C/D prediction comes to pass, that will make it the Macan S Diesel most affordable Porsche sold.

Porsche patent sketches show removable headrest wind deflector

While driving around in a convertible might seem glamorous, ask anyone with long hair and they'll likely tell you how it really is: the wind buffets, your hair goes everywhere and it's anything but glamorous. That's why you see so many convertibles driving with their tops up, their windows up or wind deflectors in place. But Porsche is apparently preparing to kick it up to the next level.
These patent drawings have leaked out, demonstrating what appears to be some new kind of wind-deflecting device being developed by Porsche. The mechanism is apparently fitted to the headrest itself and designed to keep the wind buffeting specifically around the head down to a minimum while allowing the car's occupants to enjoy the top-down driving experience.
No word on when it might hit the market, but we won't be surprised to see this kind of device appear on a future version of the Boxster or 911 Cabriolet. But nowhere else: despite the apparent leak, the patent drawings suggest that Porsche will be keeping this technology proprietary. Whether sister brands like Volkswagen, Bentley or Lamborghini will get their hands on it remains to be seen.
