2015 Porsche Cayenne S Quick Spin

There are sporty SUVs, but until the Macan came along, the Porsche Cayenne was arguably the only pure definition of a 'sports SUV, a la sports car. The second-generation Cayenne is now five years old, but still looks fresh. It's handsome without obvious effort, especially with the optional 21-inch 911 Turbo wheels. The Cayenne S replaces the old, 400-horsepower, 4.8-liter V8 with the brand-new, Porsche-developed 3.6-liter twin-turbo V6. This engine is quickly proliferating through the range – it powers the current Panamera S and the Macan Turbo. That former 4.8-liter started life as a 4.5-liter with 350 horsepower way back in 2002, specifically developed for the Cayenne, and to the end it remained a potent engine. We tried the new forced-induction V6 with 420 hp earlier this year in the Panamera S, and other than a soggy exhaust note it maintained the character of the former V8 sport sedan, with lusty power and hasty delivery. So, how's it do in the Cayenne? Driving Notes The Cayenne S version of the TT V6 gets 420 hp and 406 pound-feet of torque. That means there's 37 more lb-ft than the previous V8, and 22 more lb-ft than in the new Panamera S. Yet the 607-pound difference in curb weight between the Panamera and Cayenne means the V6 has a heavier load to lift here. And it shows – the instant response is dulled. Stomping the right foot gets the eight-speed transmission rappelling through gears to provide a little kick, but real gumption doesn't come until the turbos kick in. We're maybe talking about a second of pause compared to the Panamera, but a noticeable second. Perhaps a small price to pay for slightly better fuel economy, if you really care about such in your 420-hp SUV. Part of why we notice that second is that the Cayenne S is so right-now everywhere else that any perceived hesitation gets extra attention. It offers a specific adjustability that many sports cars don't have, with one button adjusting the three-mode air suspension and a separate Sport button tweaking the steering, throttle, gear changes, and traction control. With Sport keeping all the horses at the ready and the optional Porsche Torque Vectoring holding things steady, you don't need to step up to the GTS trim to get immediate acceleration, crisp steering, flat cornering at very un-SUV-like speeds, and tremendous stopping power from a total of 20 brake pistons. That said, the exhaust note here could also use a shot of Bruce Banner's gamma rays.

2013 Porsche 911 RSR makes official debut

Porsche is ready to go racing in 2013, showing off a new 911 RSR today that is scheduled to compete in several endurance events this year. Based on the current 991 911, the new RSR will compete in the 2013 season of the World Endurance Championship and the 24 Hours of Le Mans. It will not, however, make an appearance in a North American racing series this year.
The 2013 version of the racecar has increased in wheelbase by some four inches, features a new wishbone front suspension in place of the last-generation's McPherson strut setup and boasts a new, lightweight six-speed racing gearbox. The engine, meanwhile, is an "optimized" version of last year's car, a 460-horsepower 4.0-liter boxer six-cylinder. Extensive use of carbon fiber and polycarbonate windows help the RSR shed weight, and Porsche has also balanced the weight more evenly with a lower center of gravity.
Porsche has thoughtfully dedicated some space to celebrate the 911's 50th Anniversary, with the number 50 clearly visible in the top-down view of the RSR, as well as along the doors. Scroll down to read the full Porsche press release, below.

Audi will submit emissions fix for 3.0 TDI V6 to EPA and CARB

Audi will develop a software update for the emissions control system on Volkswagen Group's 3.0 TDI V6 and will submit the changes to the Environmental Protection Agency and California Air Resources Board for approval. If the government regulators accept it, the tweaks could end the emissions problems for an estimated 85,000 of these engines in the US in Audi, Porsche, and VW models. However, the stop-sale still covers these vehicles until further notice. Audi admits in its statement to failing to disclose three "auxiliary emission control devices" on the V6 to regulators, and US law considers one of these systems a defeat device. VW Group offered the engine in the US on the Audi A6, A7, A8, Q5, and Q7 since the 2009 model year. The mill was also available on the VW Touareg and Porsche Cayenne. The EPA filed a violation against the 3.0 TDI on November 2 because the agency reported that the engine's software contained a defeat device to circumvent emissions tests. The regulator recently extended that notice to cover these powerplants in the US from the 2009 to 2016 model years. Audi's statement vaguely estimates the price of this problem to be in the "mid-double-digit millions of euros," and the automaker could face financial punishment by regulators. "Determinations regarding potential penalties and other remedies will be assessed as part of the investigation EPA has opened in conjunction with the US Department of Justice," an EPA spokesperson told Automotive News.

That is the result of the discussions held between a delegation from AUDI AG and the US Environmental Protection Agency (EPA) and the California Air Resources Board (CARB). The updated software will be installed as soon as it is approved by the authorities. The three brands Audi, Porsche and Volkswagen are affected. Audi estimates that the related expense will be in the mid-double-digit millions of euros.
