Audi's next S7 spotted sporting Prologue-inspired nose

Our spy photographers caught the next-generation S7 testing at the Nurburgring, and this newest version, while still retaining the S7's hatchback profile, updates it with design cues from the Prologue concept. The front is the most distinctly updated part of the car, and pulls the most from the concept. The grille has been widened and given more defined corners that exaggerate the hexagonal shape. The headlights have been slimmed down and are more in line with the grille. These changes give the front of the new S7 a lower, wider look than its predecessor. Speaking of grilles, we also spot a heat exchanger tucked inside the grille opening on the left corner. We're not sure if this is an intercooler, an additional radiator or perhaps an oil cooler, but clearly something needed a bit more airflow. We don't really have any indications of what powertrain the new version will have, but it will probably have a higher output than the current 450-horsepower S7. Moving around to the back, the much-loved arching hatchback profile drops to a revised tail. The taillights, like the headlights, are more slender than they used to be, and they also appear to have been stretched closer to the center of the rear fascia. The base of the hatchback opening appears to have been widened as well. This doesn't have much of an effect on style, but it should make it easier to load cargo into the S7 and its stablemates. As for when we'll see this new hatch revealed, we're not sure. But this prototype looks close to production-ready, so we could see a debut soon, perhaps sometime next year.

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.

First official Audi R8 photo leaks

The next-gen Audi R8 makes its grand debut in a just a few days at the 2015 Geneva Motor Show. However, leaks aren't uncommon for such a highly anticipated model, and it appears that the first official shot of the future supercar is now online. Autoblog en Espanol claims this is the first leaked factory photo showing the new Audi R8 completely undisguised. The single image depicts the supercar from the front, and it looks a lot like both Audi's own official teaser and the previous blurry image from Instagram. Based on this picture, the German designers thickened the outline around the grille at the front and added vertical slats at each corner. They also removed the gentle curve in the headlights in favor of a completely angular look. While the side blades were one of the major styling features of the original, their appearance has been toned down by removing the vertical, contrasting strip running up the body. Though the exterior design seems to evolve the R8 slightly, there are some big changes for the powertrain. Audi is ditching the V8 for the latest model and opting for two tunes of the 5.2-liter V10. The standard version gets 540 horsepower, and the Plus pushes output up to 610 hp. The top trim can reportedly hit 60 miles per hour in 3.2 seconds and reach a top speed of 205 mph. Although, there are already the rumors of other variants, including a turbo V6, coming later. Related Video:
