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 drives 911 Turbos old and new

It's been forty years now since Porsche released the original 911 Turbo. And as many things that have remained a constant, a lot has changed, too: the engine has gone from air-cooled to liquid, moved up to nearly a midships layout, and drives almost exactly double the original's output to all four wheels instead of just the back set through a seven-speed dual-clutch transmission instead of a five-speed manual. It'll also reach highway speeds about twice as fast as the original. That's progress for you, and who better to compare Porsche Turbos old and new than Magnus Walker. The outlaw of the 911 scene may not look the part, but to those in the know, he's got the last word when it comes to Porsches. After searching for some time, Walker recently got his hands on a cherry of an original 930 Turbo from 1975 – the first year it was made – and had it shipped from Australia to California to add to his collection. eGarage caught up with Walker and brought along a new 991 Turbo for juxtaposition. Fortunately it also brought along a video camera or two to document the experience, so check it out in the latest video above.

Bugatti and Rimac joint venture profitable 'beyond expectations'

WARWICK, England — The joint venture between Croatian electric carmaker Rimac and Bugatti has been far more profitable than anticipated as the two brands work on developing vehicles together under one roof, Rimac's top executive said on Wednesday. "It's highly profitable and cash flow positive beyond anybody's expectations," Rimac CEO Mate Rimac told Reuters in an interview at the UK offices of the carmaker's Rimac Technology unit in Warwick. "It's such a win-win situation for everybody." Rimac added the joint venture has brought "lots of synergies going both ways." The Rimac Group comprises the Bugatti-Rimac JV, producing the electric sportscar Nevera and the Bugatti Chiron — which is owned 45% by Porsche AG — and a technology unit which supplies battery systems and powertrain components to other carmakers. Earlier this year the group raised 500 million euros ($519 million) in a new funding round. Rimac's CEO said the company has developed a "really close strategic relationship" with Porsche, which was listed by its parent Volkswagen in October. Porsche holds a 20% stake in the Rimac group. "We are really collaborating on many levels, developing and producing lots of key elements of their (Porsche's) future hybridization and electrification," he said. Rimac's CEO said the group must become more like Ferrari with a predictable, stable and profitable business before it can contemplate an initial public offering. "They (Ferrari) make projections and they always achieve," he said. "What I want to have is some kind of stability and certainty before we do an IPO because we don't want to make promises we can't keep." An IPO could happen anytime from three years to a decade from now, and could involve going public as a group or spinning off a unit, he said, but is definitely coming because "we obviously have financial investors that at some point want to exit."
