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:

Audi RS5 gets big turbocharged power and an angry new look

Menace has always been one of the keys to Audi's RS 5 coupe, from the fat wheel arches to the rumbling evocative exhaust note to the brutal straight-line performance. That's not going to change with the new version, but Audi is talking loudly and proudly about how the RS 5 debuts the new RS design language, partly in the hope that people don't labor on the disappearance of its V8 engine. Yes, the all-new RS 5 Coupe uses the same Porsche-engineered biturbo V6 as the Porsche Panamera, and uses it to such effect that it extracts 444 horsepower and 443 pound feet of torque from its 2.9 liters of displacement. Those 443 lb-ft is a full 125 more than the V8 could ever muster, and it's available from 1,900 rpm to 5,000 rpm. That kind of power is sufficient to push the RS 5 to 62 miles per hour in 3.9 seconds on the way to a limited 155-mph top speed (there's an optional 174-mph limiter, too). The all-wheel-drive Quattro RS 5 Coupe doesn't suffer much in performance in the switch from the naturally aspirated 4.2-liter V8 to the force feeding of a V6, but it remains to be proven whether the sound can be as captivating. The Porsche-sourced engine continues the current trend of "hot vee" engines, situating both of its turbochargers inside the vee-angle of the engine, and combines centrally-mounted direct fuel injectors with a short stroke to boost power and improve economy. The high-compression Miller-cycle motor also lets the RS 5 Coupe pull its consumption down 17 percent to 32 miles per gallon (or 197 grams/km of CO2 emissions) on the European driving cycle. Expect US mileage numbers to be significantly lower. The new RS 5 is also significantly lighter, pulling 132 pounds from the previous V8-powered model's mass, despite all the turbo plumbing, to weigh 3,649 pounds. A BMW M4-style carbon-fiber roof helps keep the weight down. Audi feeds its newfound V6 power through an eight-speed automatic transmission and permanent all-wheel drive, with 60 percent of the drive nominally headed to the rear end. The hard-turning sport differential is an option. Audi's reborn RS 5 rides on five-link suspension systems at both ends to keep suspension bits precisely location and improve ride quality, while sitting 0.8 inches lower than the standard A5 Coupe. It has the usual Audi Sport array of go-faster options for its go-fastest front-engined coupe, including the more aggressive Dynamic Ride Control damping system, carbon-ceramic brakes and sharper steering ratios.
