Stock Miata beats bunch of high-powered cars in wet 1/4-mile drag race

When is a stock, 167-horsepower Mazda MX-5 Miata quicker than a Chevrolet Corvette, Ford Mustang, Lamborghini Gallardo, Lotus Elise and a Porsche 911? When it's raining. Sort of.
Mazda Canada arranged a unique drag race to show off the fact that the Miata's optional power retractable folding hardtop can go from top-down to top-up in just 12 seconds flat. In this video, all six cars line up for a drag race, and it starts to rain (well, sort of - but you'll have to watch the video all the way to the end to see what we mean). The green flag is waved, and the timer starts as soon as the convertibles begin to put their tops up. But because the Miata's roof mechanism gets the car's roof back up a full 5.1 seconds quicker than the second-place car, the Mazda gets a serious advantage off the line for the actual drag race.
It's a fun video. And while we've spoiled the results (come on, the video was uploaded by Mazda, you knew the Miata was going to win), be sure to see how it all unfolds, below.

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.

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.
