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.

Audi details updated 3.0L V6 TDI engine

The brands in the Volkswagen Group have shown that they can develop some of the world's best diesel engines for passenger cars. At the Vienna Motor Symposium taking place May 8 and 9, Audi has an updated one to add to its lineup. It's launching a new version of the 3.0 TDI V6 with better efficiency and more power than the version currently in the US.
The new diesel will be offered in two tunes: 215 horsepower or 268 hp. However, Audi isn't giving away all of the new engine's secrets just yet. It says "depending on model" the mill makes as much as 442.5 pound-feet of torque and gets as much as 13 percent better fuel economy. That likely means the more powerful version gets the twist, and the other one has the better consumption, but we'll have to see.
To compare, the current 3.0 TDI offered in the US produces 240 hp and 428 lb-ft of torque. In the A6, it's rated at 24 miles per gallon city, 38 mpg highway and 29 mpg combined, according to the EPA.

2017 Audi R8 starts at $164,150 [w/video]

The new 2017 Audi R8, which offers 540-horsepower and 398-pound-foot of torque from its V10 engine alongside Quattro all-wheel drive and a seven-speed S-Tronic dual-clutch transmission, will start at $164,150 (including destination). That's about $47,000 more than the previous entry-level R8, but since that car was down two cylinders, 110 horsepower, and 82 pound-feet of torque, it's kind of an apples-and-oranges comparison. There's a much fairer comparison if we look at Audi's newest supercar in relation to the 2015 R8 V10. On the one hand, the loss of the $155,150 manual transmission model kicks the starting price up noticeably, but perhaps in recognition of that, Audi hasn't adjusted the two-pedal R8 V10 at all. It's the same price as the 2015 model while adding 15 more horsepower, seven more pound-feet of torque, and a tenth of a second to the 0-60 time, which is now estimated at 3.5 seconds. Don't worry – the 2017 R8 adds four miles an hour to its predecessor's 195-mph top speed. While under-the-skin changes for the standard R8 V10 may look modest at first glance, the updates Audi added to the V10 Plus are significant, and the automaker has raised the price to reflect that fact. On the one hand, the new range-topper was kicked up by $7,400, to $191,150. On the other hand, power is up by 60 ponies to 610 hp, and torque has jumped from 398 lb-ft to 413. The 0-60 time has been trimmed by a tenth of a second, and owners will also be able to hit 205 mph, up from the old V10 Plus' 198-mph max. To reflect the new pricing announcement, Audi prepped an entertaining video featuring Radio Le Mans announcer John Hindhaugh to "hand the baton" from the original R8 to its second-gen successor.
