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:

2015 Porsche Cayenne S E-Hybrid

Think of the electric motor in the facelifted 2015 Porsche Cayenne S E-Hybrid as the cream filling in an Oreo cookie. Under the hood of this plug-in hybrid crossover is a 333-horsepower, supercharged 3.0-liter V6 with a 95-hp synchronous electric motor sandwiched between it and an eight-speed Tiptronic automatic transmission. The clutched powertrain allows pure combustion, pure electric or a combination of both to drive all four wheels through Porsche's permanent all-wheel-drive system.
Differentiating itself from the Panamera S E-Hybrid sedan, which shares the same basic powertrain and stores energy in a 9.4-kWh battery, the Cayenne crossover is fit with a more robust 10.8-kWh lithium-ion battery that delivers an estimated pure-electric driving range of up to 22 miles at speeds of up to 78 miles per hour.
To be one of the very first US media members to sample Porsche's latest fuel-efficient crossover, the automaker flew us to Frankfurt, Germany, to test the five-passenger Cayenne S E-Hybrid on its home turf.

Best new convertibles for 2024 and 2025

If you’re here, then youÂ’re already in the right mindset. Convertibles rule, and we have all the best convertibles listed for you further below. Driving around with the top off is an experience you need to live to fall in love with. When the weatherÂ’s right, youÂ’re on a proper bit of road, and the car youÂ’re in is a good one, few automotive experiences can top it. The experience is extra special when you have a musical exhaust note filtering directly into your ears and echoing off the landscape around you. And while rolling the windows down and opening a moonroof can get you part of the way there, it's nothing like feeling the wind wash over you with absolutely no roof overhead. The downsides can be just as harsh as the upsides when youÂ’re in the wrong conditions, though. Convertibles are typically worse to live with in cold climates, and driving around with the top up frequently means you might be subject to more road noise and worse visibility than an equivalent coupe. And when it comes to pure performance, convertibles are inherently compromised from a weight and structural rigidity perspective. All that said, we still think the upsides outweigh the compromises if your number one objective is to simply have fun. ItÂ’s a good thing then that there are a ton of great convertibles for sale these days. And no, the list of possibilities isnÂ’t as long as it used to be. Long-running standbys like the Mercedes-Benz E-Class and C-Class Convertibles are gone (replaced by the one CLE-Class). And so are others like the Audi TT Roadster, Fiat 124 Spider and Nissan Z Roadster. Nevertheless, opportunities abound from the ultra-cheap and fun, to physics-defying supercars and everything else in between. WeÂ’ll give you options for which new convertibles we think are the best below, so read on to find out.   Mazda MX-5 Miata Pros: Lightweight and compact; great engine and transmission combo; one of the most raw and pure driving experiences out thereCons: Not great for tall people; infotainment is dated; tiny trunk Read our Mazda MX-5 Miata Review Miata is always the answer, right? In this case, that rings even more true than usual. In fact, you could stop reading this list right here and go buy a Miata and youÂ’d likely be just as happy driving it around as you would be in any of the more expensive offerings that follow. ThatÂ’s just the magic of the MX-5.
