Audi, Porsche ensnared in new Volkswagen cheating allegations

The scope of the Volkswagen emissions cheating scandal that has enveloped the global automaker for the past six weeks widened Monday. Now, some of the automaker's premium brands are further ensnared in the mess. Officials with the Environmental Protection Agency issued a second notice of violations Monday, accusing Volkswagen of violating the Clean Air Act by using defeat devices that circumvent emissions testing on diesel versions of certain vehicles equipped with 3.0-liter engines. Roughly 10,000 vehicles in the United States contain the illegal software, the EPA alleges. That's a far smaller number than the 482,000 vehicles affected by the first instances of cheating, which Volkswagen confessed to in September. But this latest violation alleges the cheating occurred broadly through the Volkswagen empire and includes vehicles from the Porsche and Audi brands. Audi had one model, the A3, involved in the first round of announced violations. But the brand, which has enjoyed skyrocketing sales in the US in recent years, is more extensively involved in violations announced Monday. The 2016 Audi A6 Quattro, A7 Quattro, A8, A8L and Q5 are among the cars which contain the illegal software, which permits the cars to emit nitrogen oxide at up to nine times the allowable thresholds set in the Clean Air Act, according to the EPA. The 2015 Porsche Cayenne and '14 Volkswagen Toureg SUV are also affected. "There is clear evidence of additional violations and it's important to put Volkswagen on notice and to inform the public." - Janet McCabe. "Audi, which has been on a roll in terms of sales, reputation and image of late, now is being drawn deeper into the quagmire," said Michelle Krebs, senior analyst for Autotrader. "Previously, only the low-volume A3 was under scrutiny, but now Audi's core models are under fire." Audi officials did not respond to a request for comment Monday. In a written statement issued late Monday afternoon, a Porsche spokesperson said, "We are surprised to learn this information. Until this notice, all our information was that the Porsche Cayenne Diesel is fully compliant." Porsche said it would cooperate with authorities.

Sunday Drive: A new Rambo Lambo takes center stage

Surprise! Autoblog readers love fast cars. Doesn't matter what shape; doesn't matter what size. As long as it's got big power, wicked acceleration, and ludicrous speed, you're interested. Take, for instance, the brand-new Lamborghini Urus. It's got a 4.0-liter twin-turbocharged V8 sending 641 horsepower and 627 pound-feet of torque through an 8-speed automatic transmission to all four wheels. It hits 62 miles per hour in 3.6 seconds, and has a top speed of 189.5 mph. Ludicrous speed? Check. And although you'd be hard pressed to draw a line straight back from the upcoming Urus to the old, off-road-ready LM002, at least you can say that Lamborghini does have a history of producing overpowered SUVs. A 5.2-liter V12 engine producing 444 horsepower and borrowed from the Countach certainly qualifies as big power, especially considering this was in the 1980s and '90s. A prime example just sold for nearly half a million bucks. Moving along to more traditional sportscars, we got a sneak peek at the next Porsche 911's interior, thanks to some intrepid spy photographers. And we spy with our little eyes some major changes to the quintessential German sportscar. Finally, we round out this Sunday Drive with two First Drive reports. Both are German, but past that, they couldn't be more different. Either way, ludicrous speed is all but guaranteed by either one.

Ruf RGT 4.2 offers 518 hp of naturally aspirated power

Ruf has a reputation for building some fast interpretations of the Porsche 911, and the company's latest RGT 4.2 at the Geneva Motor Show provides an interesting point of comparison compared to the new GT3 RS that's debuting there. In terms of pure power, the Ruf wins out. The company crafts a flat six with 4.2-liters of displacement making 518 horsepower and 369 pound-feet of torque with a top speed of 200 miles per hour. In contrast, the latest GT3 RS gets 500 ponies and 338 lb-ft of twist from its direct-injected 4.0-liter mill. Depending on your desires, the RGT 4.2 might have the preferred gearbox too with its six-speed manual versus the Porsche's PDK. Styling is also going to come down to personal tastes between these two. The RGT 4.2 has an almost old-school racing look with its bolted-on fender flares, five-spoke wheels, thick carbon fiber rear wing and lower front air dam. Inside, there's also an integrated roll cage. The RS, on the contrary, appears thoroughly modern with its big fender intakes at the back, slashes just behind the front wheels, CFRP hood and magnesium roof. Check out Ruf's naturally aspirated monster on the Geneva show floor in the gallery, above. The RGT 4.2 maintains a long tradition of Ruf supercars with its outrageous driving performance. Unveiled in 2000, the first RGT was characterised by its powerful, torquey normally-aspirated flat-six engine. With a significantly reduced all-up weight and sports-oriented suspension system, the RGT was an extremely impressive driving machine.Now, in 2015, the RGT remains true its original concept, though its external appearance is clearly more athletic. The wheel arches are more bulbous and the front facade presents huge round air intakes for more effective cooling. The chassis is reinforced by RUF's hallmark Integrated Roll Cage (IRC). Propulsion is provided by its virile 4.2-litre six-cylinder, normally-aspirated engine, developing 525bhp and 500Nm of torque, featuring dry sump lubrication with external oil tank.
