NHTSA closes probe into 2011 Porsche 911 coolant leaks

The National Highway Traffic Safety Administration has announced that it will end its investigation into rapid coolant loss in 24,635 Porsche 911s built between 2001 and 2011. The models affected included the standard 911, GT2, GT3 and Turbo, as well as their variants (GT2 RS, GT3 RS and Turbo S).
NHTSA was investigating for "rapid coolant loss caused by coolant pipe-fitting failure, allegedly resulting in vehicle disablement and/or loss of vehicle control due to reduced traction for the affected vehicle or following traffic," according to the regulators website. "Most of the leak complaints did not appear to involve complete separation of the fittings and many were detected when the vehicle was parked," said NHTSA's statement.
There were 63 complaints and 336 warranty claims, although the investigation was initiated after ten complaints from customers. There have been no reports of crashes or injuries attributed to rapid coolant loss.

VW adding particulate filters to gas engines

Volkswagen is working hard to overcome the PR disaster that is its diesel emissions scandal, and part of its efforts is focusing, weirdly, on petrol engines. Starting in June 2017, the embattled German automaker will add particulate filters to the gas-powered Volkswagen Tiguan and Audi A5. The change will eventually impact nearly every direct-injected gas engine the VW Group makes. Audi? Particulate filter. Seat? Particulate filter. Even Bentley is going to get the tech, all in a bid to reduce soot emissions by 90 percent. In fact, by 2022 VAG expects 7 million of its vehicles to boast the emissions-cleaning tech, which has long been a fixture on diesel engines. "Following increases in efficiency and lower CO2 output, we are now bringing about a sustained reduction in the emission levels of our modern petrol engines by fitting particulate filters as standard," Volkswagen Group research and design boss Dr. Ulrich Eichhorn said in a statement. "In the future, all models will be equipped with the latest and most efficient SCR catalytic converter technology." VW's initial rollout focuses on the 1.4-liter, turbocharged Tiguan and the 2.0-liter, turbocharged A5. Considering the popularity of the 2.0-liter across the VW range, we'd expect it's only a matter of time before VW expands its particulate filters tech to additional gas-powered vehicles.

2014 Porsche Cayenne Platinum Edition is the ace of base

If there's one automaker that certainly doesn't skimp on the special edition models, it's Porsche, and here at the 2014 Detroit Auto Show, we're getting our first look at yet another unique take on one of the company's most popular models. It's called the Cayenne Platinum Edition, and while many special models build off of higher-trim vehicles, this one adds a bit of flair to the most basic version of the luxury SUV.
The Platinum Edition is available on Cayennes with the base 3.6-liter V6 or the 3.0-liter turbodiesel V6. Platinum models are set apart from other models with the addition of silver exterior accents on the grilles, window trim and rear spoiler, as well as the two-tone, black-and-beige interior scheme. It also comes standard with the eight-speed Tiptronic S transmission, Power Steering Plus, Park Assist, the Convenience Package and Bose audio.
The cost of entry? $63,000 for the naturally aspirated Cayenne or $66,900 for the diesel. That's a full $13,000 more than the base model, but Porsche says it's actually a bargain as opposed to selecting all of those options individually. Have a look below for Porsche's official release.
