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.

Magnus Walker turbocharges his love for the Porsche 911

He's had his fill of early, long-hood Porsche 911s - he owns at least one from each model year, from 1964 to 1973 - so Magnus Walker, a fanatic of the Stuttgart, Germany-based automaker, recently set his sights on the early Porsche 930, as documented by this XCAR video called 'Turbo Fever.' Let us translate: pretty soon Walker will own all of the earliest, non-intercooled 911 Turbos - at least one from each model year, starting at 1975 and ending at 1977 (though the 1975 911 Turbo Carrera never officially was imported to the US by Porsche, so it'll be tougher to find one Stateside).
Any Porsche enthusiast can tell you why they love their car, and it often comes down to the small details that differentiate one model year from another. One of many examples is the mid-'80s 928. They look similar, but the basic difference between a 1984 Porsche 928 S and a 1985 928 S (US-spec) is two camshafts and 54 horsepower, though each car's V8 has its own pros and cons. We'll let Magnus Walker tell you all about the 930 and what makes the first three years special, as he's becoming quite the expert on early, air-cooled 911s. When the nearly 15-minute mini-documentary was filmed, which you can view below, he already had added four early 930s to his collection!

Porsche 911 GT1 Evo up for grabs in Monaco valued at $3M

On paper, Porsche didn't do a flagship supercar in between the 959 and the Carrera GT. In reality, it did. Sort of. It was the strassenversion of the 911 GT1, a homologation special based on a spectacularly successful racing car. And RM Sotheby's has a standout example consigned for its upcoming sale in Monaco. What you're looking at is a 911 GT1 Evolution that served as the mid-point in the GT1's development, following the original and followed in turn by the GT1-98 that won the 24 Hours of Le Mans that year. One of just fourteen 911 GT1s held in public hands, chassis number GT1 993-117 won the Canadian GT Championship three years running, and is the only GT1 Evo that was ever registered for use on public roads. RM Sotheby's anticipates that it will fetch between $2.9 and $3.25 million when it crosses the auction block in May, marking the first time that this particular example has come up for auction. That would make it considerably more valuable than the GT1 Evo Gooding & Company sold at Amelia Island in 2012 for $1.26 million, according to Sports Car Market. Of course, the Porsche isn't the only notable item the auction house has lined up for the sale during the Grand Prix de Monaco Historique weekend. There's a pair of 1930s German convertibles – one Mercedes 540 K and one Horch 670 – valued at about the same level as the 911 GT1, a Tucker 48 (~$1.6m), and Niki Lauda's debut March 711 grand prix racer (~$550k). Those are some tempting sets of wheels, and we'll be watching to see how they fare two months from now.
