EPA discovers defeat device in more VW TDI engines

In a sternly worded letter, the United States Environmental Protection Agency has issued a new set of allegations against Volkswagen claiming that so-called emissions defeat software has been found in the company's 3.0-liter TDI V6 diesel engines. This is a completely different engine than the 2.0 TDI that has already been identified as an emissions cheater. In addition to VW, the EPA has included Audi and Porsche in this notification, as the non-compliant engine has been used in vehicles from all three manufacturers from model years 2014 through 2016. The EPA claims that cars equipped with the 3.0 TDI engine know when they are being tested for emissions, and their on-board computers switch into a mode designed to pass the stringent requirements in the United States for diesel exhaust. Vehicles sold in the United States with this engine include the 2014 VW Touareg, 2015 Porsche Cayenne, and 2016 Audi A6, A7, A8L and Q5. The EPA says there are 10,000 vehicles currently on the road with this second defeat device, along with an unknown number of 2016 models either on dealer lots or in the driveways of consumers. According to the EPA, VW's 3.0-liter TDI, like the 2.0 TDI that was found to circumvent US regulations, has code in its computer specifically written to intentionally put the vehicle's engine into a mode that allows it to meet exhaust requirements. When the vehicle is unhooked from testing equipment, it will go back into a mode that emits nine-times higher nitrogen oxide emissions than is allowable under US law. "VW has once again failed its obligation to comply with the law that protects clean air for all Americans," said Cynthia Giles, Assistant Administrator for the Office for EPA's Enforcement and Compliance Assurance. "All companies should be playing by the same rules. EPA, with our state, and federal partners, will continue to investigate these serious matters, to secure the benefits of the Clean Air Act, ensure a level playing field for responsible businesses, and to ensure consumers get the environmental performance they expect." Richard Corey, Executive Officer of the California Air Resources Board, said in a statement, "Today we are requiring VW Group to address these issues. This is a very serious public health matter. ARB and EPA will continue to conduct a rigorous investigation that includes testing more vehicles until all of the facts are out in the open." This story will be updated as new information becomes available.

Porsche Cayman, Boxster caught in GTS trim

A few months ago, we reported on some leaked information from an internal presentation for upcoming Porsche models. This included details about the Macan and the 911 Targa, which we now know to be true, but there was also talk about GTS versions of the Cayman and Boxster.
Well, it appears we're now getting our first look at these GTS models, as our spy photographers have just snapped a pair of Porsche prototypes out testing - one Cayman and one Boxster.
Right off the bat, we can see that both GTS-branded cars will get a slightly tweaked exterior with new fascias (bringing LED daytime running lights to the Cayman) and air diffusers at the rear. The true gem of these cars will be the added horsepower to the tune of 340 horsepower - a 15-hp bump. A manual transmission will likely be standard, as will Porsche Active Suspension Management (PASM).

Evo rediscovers true love in the new Porsche 911 GT3 RS

Evo is on record as loving the Porsche 911 GT3. In fact the only time the GT3 hasn't won its Car of the Year award was when there wasn't a new one to contend for top honors, and in 2009 (when the 997.2 GT3 lost out to the Lotus Evora). By all accounts, then, Evo ought to love the new GT3 RS. Fortunately that's just what the British enthusiast's publication has gotten its hands on for this latest video. After Porsche went a bit softer with the current 911 GT3, the RS has been toughened up to greet the most hardcore of Zuffenhausen's faithful. It was revealed just a few months ago at the Geneva Motor Show, with a 4.0-liter atmospheric boxer-six driving 500 horsepower and 338 pound-feet of torque to the rear wheels – exclusively through a dual-clutch transmission. That last bit might be enough to make the snobbiest of purists scoff, but it wasn't enough to keep Chris Harris from loving it. Find out what his former compatriots at Evo have to say from this first drive.
