VW orders external probe into diesel emission scandal

There are well over 480,000 Volkswagen-made, diesel-powered vehicles currently traveling roads in the United States that do not meet the Environmental Protection Agency's emissions requirements. This, as you can probably imagine, is a very big deal, and has led VW CEO Professor Doctor Martin Winterkorn to release an official statement on the matter. "I personally am deeply sorry that we have broken the trust of our customers and the public," he said. It's important to note that these vehicles run software with a so-called "defeat device" that kicks in when the on-board computer senses that it is being tested for emissions. When the car is operating normally – in other words, when its exhaust isn't being sniffed – the cars do not meet US emissions standards. According to the EPA and the California Air Resources Board, affected cars emit as much as 40 times the allowable level of certain pollutants. "We will cooperate fully with the responsible agencies, with transparency and urgency, to clearly, openly, and completely establish all of the facts of this case," according to Winterkorn, who added, "Volkswagen has ordered an external investigation of this matter." It's not yet known who will carry out this investigation. At present, there are still a number of 2015 Volkswagen models on dealer lots that do not meet emissions requirements. VW has issued a stop sale on vehicles equipped with the 2.0-liter TDI diesel engine. What's more, the German automaker has been barred from selling 2016 model-year vehicles that use this engine, according to The Detroit News. Last year, diesel vehicles made up about 22 percent of all VW sales, which means these restrictions will have a big impact on the brand's sales performance until a remedy is found and the vehicles are approved for sale. Interestingly, the EPA has started a campaign of sorts to test vehicles from other automakers that sell diesel-powered vehicles in the United States to make sure they comply with emissions requirements under all operating circumstances. The EPA says it "will be reviewing [its] compliance protocols and introducing ways in which [it] can effectively test not only for emissions performance but also for the potential presence of defeat devices," according to a statement provided to The Detroit News.

Audi's fastest cars won't catch your drift

"I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." – Stephan Reil Drift modes are popping up in sports cars all over the world, but Audi Sport development boss Stephan Reil refuses to have anything to do with them, insisting they're a waste of time and tires. So if you want to show off with a wild-looking, tire-smoking, perfectly controlled drift in an Audi Sport model, you will have to brush up on your car control, not your button pushing. "No drift mode. Not in the R8, not in the RS3, not in the RS6, not in the RS4," Reil said. "I don't like them. I do not see the reason for them. We do not see the sense in sitting there burning the back tires. It's not fast." That seems a bit like Reil and his team are missing a trick that is proving popular with enthusiast buyers and isn't technically difficult to do. It's also a whole lot safer than holding down the skid-control button for long enough to switch off all the electronic safety nets, which Audi Sport will actually let you do. "You can do it yourself [drifting] with the ESP off, if you hold it [the button] for three seconds," Reil challenged. "Then it will not intervene for you even when it [the car] is fully out of control, because that's what you asked it not to do. "You wanted the full control by pushing that button. You got it." Almost every fast car, from Ford to Ferrari, now comes with (or soon will) a drift mode so drivers can just stomp on the gas and turn the wheel to instantly look like rally stars. The dangers of do-it-yourself drift control (which our forefathers used to call "driving") make up most of the moral defense for the companies that use the computer-controlled versions. While critics have called drift modes irresponsible, proponents argue that it is far safer than switching off all the safety nets, because there is still a level of skid-control safety behind it. "Drift control is a lot safer than just turning everything off," BMW M chief Franciscus van Meel said during the launch of the M550i xDrive. "The drivers can enjoy the car on a track but it still has another level of safety to catch them if they make a mistake."

Audi S5 spied

We only recently saw the next-gen Audi A5 testing for the first time with its sleeker design covered in camouflage. Now, here's a well-concealed glimpse at of the higher-performance S5 for comparison against the standard coupe. With so much swirling camouflage picking out the differences between the two models isn't easy, but there are a few tweaks to notice. The intakes on the front fascia are just a little bigger, hinting at the increase in power. The brakes also appear to be larger, especially when comparing them at the rear. Of course, the most obvious changes are the dual exhausts poking out each corner of the speculative S5. While more power is assured for the S5 over the A5, the exact powerplant isn't officially known yet. Rumors suggest Audi using a tuned version of the supercharged 3.0-liter V6 making between 340 horsepower and 350 hp, at least for the S4. The switch to the MLB Evo platform means less weight to haul around no matter what's under the hood, though. The next-gen A4 should provide some more hints about the future of the lineup when it launches at the Frankfurt Motor Show in September, and the coupes are expected to join the lineup later.
