2016 Porsche 919 Hybrid sharpens up to defend its titles

Porsche made a clean sweep of LMP1 racing last season, winning the 24 Hours of Le Mans as well as the FIA World Endurance Championship for both drivers and manufacturers. And now that it's back on top of the podium, it's not about to step down again without putting up a fight. To that end, witness the newly revised 919 Hybrid. Revealed ahead of the season's start with the Prologue event at the Paul Ricard circuit in France, the 2016 Porsche 919 Hybrid is an evolution of the version that debuted in 2014 and trounced the competition in 2015. But Audi and Toyota – with their similarly revised R18 and TS050 – will be at least as hungry this year to dethrone Porsche as Porsche will be to retain its titles, so the racing engineers in Weissach have made made a number of revisions. The chassis and basic engine architecture, of course, are the same, with a two-liter turbocharged V4 assisted by a brake energy recovery system at the front and exhaust energy recuperation at the back. But the engine now uses less fuel, so it can run longer between pit stops – a vital element of the strategy when racing for hours on end. The aerodynamics were made more adjustable so that the team can switch between three packages depending on the type of track they're running. While they were at it, those notoriously exacting German engineers managed to cut some excess weight out as well. And instead of the three different color liveries like last year, this season the 919 Hybrid will run under a common livery of black, white, and red – which hopefully won't get mixed up with those of its rivals from Audi and Toyota. We guess we'll all find out when the season kicks off in earnest at Silverstone in mid-April. This content is hosted by a third party. To view it, please update your privacy preferences.

World debut of the new 919 Hybrid: Two days before the official Prologue for the FIA World Endurance Championship (WEC) at Paul Ricard, France, Porsche is presenting its race car for this season. Strong development characterises the new 919 Hybrid' technology. The powertrain became even more efficient, the aerodynamics were even more specific for the various race tracks and the weight of single components was even more reduced.

CARB has 20 days to confirm VW's 3.0-liter TDI emission fix

VW's diesel scandal has been in the headlines since last September, but solving the problem it proving difficult. Volkswagen Group has submitted a proposal to the California Air Resources Board (CARB) and the Environmental Protection Agency (EPA) to fix about 85,000 vehicles with the 3.0-liter diesel V6 in the US, Reuters reports. CARB now has 20 business days to test if the plan actually reduces emissions. If accepted, VW could finally begin a recall and end the stop sale on vehicles with these engines. In a statement, CARB pledged to, "respond following a thorough and complete review to make sure the plan addresses the presence of the illegal defeat device and follows the necessary environmental, vehicle and public health and safety regulations." Neither CARB nor the EPA outlined the proposed repairs, but Porsche CEO Oliver Blume already suggested the fix for the engine in the diesel Cayenne. Examples from 2013 and 2014 allegedly need a new catalytic converter and software update, and those from 2015 and 2016 only need the improved code. It's not yet clear whether this procedure would work for all models with the 3.0 TDI. While the EPA issued the notice of violation against VW's 2.0-liter four-cylinder diesel in September, the first one for the 3.0-liter V6 came in early November. By the end of the month, the agency broadened the scope to about 85,000 vehicles, including some examples of the VW Touareg, Audi A6, A7, A8, Q5, Q7, and Porsche Cayenne. The affected companies issued stop sales on new models with the engine. Audi eventually admitted to regulators that it didn't disclose three auxiliary emission control devices in the powerplant's code and promised to develop a software update to fix the problem. CARB gave the automaker 45 business days to submit the proposed solution. If accepted, this repair would allow VW Group to end part of the emissions scandal, but there's no guarantee the regulators consent to this solution. Just a few weeks ago, CARB looked at the automaker's plan to fix the 2.0-liter TDI and rejected it, claiming a lack of detail.

Audi CEO's Dieselgate arrest threatens fragile truce among VW stakeholders

FRANKFURT — The arrest and detention of Audi's chief executive forces Volkswagen Group's competing stakeholders to renegotiate the delicate balance of power that has helped keep Audi CEO Rupert Stadler in office. Volkswagen's directors are discussing how to run Audi, its most profitable division, following the arrest of the brand's long-time boss on Monday as part of Germany's investigations into the carmaker's emissions cheating scandal. The supervisory board of Audi, meanwhile, has suspended Stadler and appointed Dutchman Bram Schot as an interim replacement, a source familiar with the matter said on Tuesday. Schot joined the Volkswagen Group in 2011 after having worked as president and CEO of Mercedes-Benz Italia. He has been Audi's board member for sales and marketing since last September. The discussions risk reigniting tensions among VW's controlling Piech and Porsche families, its powerful labor representatives and its home region of Lower Saxony. VW has insisted the development of illegal software, also known as "defeat devices," installed in millions of cars was the work of low-level employees, and that no management board members were involved. U.S. prosecutors have challenged this by indicting VW's former chief executive Martin Winterkorn. Stadler's arrest raises further questions. Audi and VW said on Monday that Stadler was presumed innocent unless proved otherwise. Munich prosecutors detained Stadler to prevent him from obstructing a probe into Audi's emissions cheating, they said on Monday. Stadler is being investigated for suspected fraud and false advertising. Here are the main factors deciding the fate of Audi. Background: Audi's role in Dieselgate Volkswagen Group was plunged into crisis in 2015 after U.S. regulators found Europe's biggest carmaker had equipped cars with software to cheat emissions tests on diesel engines. The technique of using software to detect a pollution test procedure, and to increase the effectiveness of emissions filters to mask pollution levels only during tests, was first developed at Audi. "In designing the defeat device, VW engineers borrowed the original concept of the dual-mode, emissions cycle-beating software from Audi," VW said in its plea agreement with U.S. authorities in January 2017, in which the company agreed to pay a $4.3 billion fine to reach a settlement with U.S. regulators.
