New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

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.

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. "The over 900 hp strong Le Mans Prototype is ready for the title defence," said Fritz Enzinger, Vice President LMP1.
