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:

2017 Porsche 911 Carrera experienced from the passenger seat

Autoblog joins Porsche for Rennsport Reunion V at Mazda Raceway Laguna Seca, the fifth international gathering of all things Porsche. If you've ever had a picture of a Porsche on your wall or dreamed of owning a certain model, either that very car or one just like it is here. Watching three 917 racers blaze over the rise at the front straight and down into turn one can make a viewer think, "So this is how Steve McQueen felt..." It was a modern Porsche that delivered one of the highlights of the first day, though: we rode shotgun for three hot laps of the track in the new turbocharged 991.2-series 911 Carrera S, with Thomas Krickelberg, director of powertrain for the 911 model line, our pilot. We cornered him and August Achleitner, vice president of the 911 product line, for a few questions about the changes. What do you call the standard 911 now that it has turbocharged engines? Carrera. If you're wondering what to call the standard 911 now that they have turbocharged engines, the answer is: Carrera. Krickelberg said, "In-house we call them 'little turbo' and 'big turbo,'" but the Carrera is a model line within the 911 model line, the big boy 911 Turbo is a second model line within the 911 family. One will continue to be called Carrera, the other simply Turbo. The move to turbocharging came to serve the twin kings of performance and fuel economy, but engineers played around with numerous configurations. A non-turbo engine displacing about 4.0 liters – that's as big as the 9A1 engine block can go – was considered, but that setup couldn't deliver the desired fuel efficiency. Krickelberg said engineers considered a small-displacement block of around 2.0 liters, but that was abandoned because "takeoff behavior was worse" because the turbo was called upon to do too much of the heavy performance living. Krickelberg added, "Not only that, but there was a too big a gap between real-world fuel economy and homologation fuel economy." Base Carrera and the Carrera S models haven't used the same engine displacement since the 996 series departed at the end of 2004. Achleitner said, "We found 3.0 liters is the best solution to get the best mix of fuel and air in combustion chamber - it offered the best geometry, bore and stroke, and the size of the walls.

The 1994 Porsche 911 Speedster only looks weirder with age

The 1994 Porsche 911 Speedster is undoubtedly a rare car, and it's even rather quick by the standards of the era. However, the designers weren't at their best when they created the odd shape at this model's rear. MotorWeek remembers this classic Porsche's exciting performance and weird look in its latest Retro Review. The Speedster's design isn't all bad. The front end still looks fantastic thanks to the nose of the 964-generation 911 and a steeply raked windshield. We can even live with the body color wheels. However, things get much worse at the rear where the hard cover, which hides the roof, gives the convertible a hunchback. As MotorWeek shows, fitting the manual top is quite fiddly. Porsche might have been better off from a styling perspective by leaving the back smooth and completely ditching the complicated roof. You can't get a good look at the weird rear from the driver's seat, and MotorWeek says that the Speedster excels once you're behind the wheel. The handling and braking are reportedly especially good. Sport seats grip the driver closely, and even with 247 horsepower, the convertible gets to 60 miles per hour in 5.4 seconds. With the weather starting to warm up, it sounds like a great experience, and you can imagine taking a ride in MotorWeek's latest video. Related Video:
