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.

Autocar pits Porsche 911 Turbo S against Formula 4 racer

There is a long-running argument among performance car fans: power vs. weight. In one corner you get cars generally with small engines making modest numbers but able to corner like they are telepathic, and in the other there are big thumping mills that are rocketships in a straight line but lumber in the turns. Autocar takes an interesting look this continuum in a recent video pitting a 552-hp Porsche 911 Turbo S against a 185-hp Formula 4 racecar. It hopes to find whether the Porsche's huge power advantage is enough to defeat the better grip and aero offered by the nimble racer.
There's no doubt that the Porsche is an utterly fantastic road car. The 911 Turbo looks mean with all of those intakes to suck in cool air, and it backs up the posture with huge amounts of grip available thanks to its all-wheel drive-system. However, at 3,538 pounds, it's a bit of a porker compared to the 1,135-pound Formula 4 car. The open-wheel car boasts just a 2.0-liter naturally aspirated four-cylinder from Ford and a six-speed sequential-manual gearbox, but it has loads of downforce to make up for it.
It shouldn't be a surprise that the formula car wins in the corners. After all, that's what it's made for. So do you think the massive horsepower superiority of the Porsche is enough to even the playing field? Scroll down to watch the video and find out, and even if you're not curious of the winner the 911 does some mean powerslides.

Porsche announces four flavors of updated Cayenne [w/video]

The new Macan may be getting all the attention lately, but Porsche hasn't forgotten about its larger crossover – the one that put it on the map in 2002 and on the road to profitability, with over half a million sold so far. So to keep the Cayenne at the top of its game, Porsche has announced several key upgrades for the 2015 model. For starters, Porsche has updated the Cayenne's appearance with new front- and rear-end styling. The front bumper, fenders and hood are entirely new, with air fins flanking the nose to direct air into the intercoolers (each model now being artificially aspirated), and new bi-xenon headlamps and daytime running LEDs on every model but the Turbo, which goes all-LED. Around back there's also new taillights, tailgate handle, lower rear fascia and exhaust pipes. Meanwhile the interior has been upgraded with a 918-derived sport steering wheel and reformed rear seats with available ventilation. The bigger news is under the engine bay, where Porsche is offering four choices. The base model is gone as the range starts with the Cayenne Diesel, followed by the Cayenne S, the new Cayenne S E-Hybrid and the top-of-the-line Cayenne Turbo. The Diesel model carries over the same 3.0-liter turbo diesel with 240 horsepower. The Cayenne S however packs a 3.6-liter twin-turbo V6 that's similar to the one found in the Macan Turbo and packs the same 406 lb-ft of torque but more power at 420 hp, 20 more than either its little brother or the model it replaces to reach 62 mph in 5.2 seconds. The new Cayenne S E-Hybrid makes Porsche the world's only car manufacturer to offer three plug-in hybrid models. Porsche has also ported over the powertrain from the Panamera S E-Hybrid to make what Porsche refers to as "the first plug-in hybrid in the premium SUV segment" and, along with the 918 Spyder, make it (almost unbelievably) "the world's only car manufacturer to offer three plug-in hybrid models" (unless, of course, you count the Opel/Vauxhall Ampera as separate from the Chevy Volt and Cadillac ELR). The system mates a 3.0-liter supercharged V6 with 333 hp to an electric motor with 95 hp to give it a combined output of 416 hp (more than the diesel and almost as much as the S) to propel it to 62 in 5.4 seconds, hit an all-electric top speed of 78 mph and an all-out top speed of 151 mph – offering a substantial improvement over the previous Cayenne S Hybrid.
