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.

Five reasons to love, or hate, the culture of German cars

A few months back, we took a 500-foot view of the culture of American cars, dissecting prides and prejudices on our way to the conclusion that automotive allegiances can be simultaneously embraced and derided. We had so much fun with the narrative that we decided to do it again, this time taking a look at Germany and its world-renowned lineup of automakers, including the likes of Audi, BMW, Mercedes-Benz, Porsche and Volkswagen, among others. Join us below as we discuss the points and counterpoints that make or have made the German auto industry what it is today. And remember, Germany did pretty much invent the automobile, after all... The V12 Engine If America is known for the proliferation of the V8 engine, an argument could be made that Germany owns the V12. Yes, of course, other companies have created V12 engines – Ferrari, Jaguar and Lamborghini immediately come to mind – but the big 12-cylinder powerplants from BMW and Mercedes-Benz, in particular, have proven to be some of the most effortless, luxurious and downright over-built engines the world has ever seen. These days, having 12 cylinders is more a case of wretched excess than ever before, and yet, you can still stroll into your local BMW or Mercedes dealership and get a brand-new 760i, S600 or even an over-the-top G65 AMG, efficiency be damned. Best of all, since the majority of these German powerhouses depreciate as fast as an anchor sinks, nearly any auto enthusiast who dreams of a dozen cylinders can satisfy their carnal desires.

If your compression-ignition fantasies err more on the side of fuel savings, that's no problem, either. Audi, BMW, Mercedes and Volkswagen have got you covered, with engines starting as small as 800 cubic centimeters (Smart Fortwo). If you want something a little more practical, it's hard to argue with a VW Golf TDI, which will provide plenty of space for you and three of your best friends, plus a fair bit of luggage, all while returning 50-ish miles per gallon. For the purposes of this discussion, we'd rather focus on the asinine levels of torque provided by Germany's high-end diesel engines than the lower-end fuel sippers.

Spyker C8 Aileron to come back with supercharged power?

The new B6 Venator wasn't the only vehicle on display at the Spyker booth at the 2013 Geneva Motor Show. The company still has its C8 Aileron on offer, and Road & Track has word of a potential powerplant upgrade for the long-running machine.
Since its introduction in the year 2000, the C8 has used a 4.2-liter V8 engine sourced from Audi, which, in base form, offers up 400 horsepower. Though it's a great powerpant, that's simply not enough power in this day and age - after all, if a car is going to be called super, it needs to offer more ponies than something as mundane as the Ford Mustang GT.
According to R&T, John Walton, Chief Commercial Officer at Spyker, indicated that a new engine supplier may be in the works. "[The Audi-sourced V8] really hasn't got enough bang for the buck. To be honest, every supercar needs to have something that begins with a '5' today. That's why we're supercharging the car in the future, which will take it to over 500-hp," said Walton.
