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.

Porsche 911 GT3 dukes it out with MP4-12C on track and GT-R on spectacular roads

The Porsche 911 GT3 has always been a favorite among auto journalists and car enthusiasts alike, but with the introduction of the new 991-generation GT3, which is the first GT3 with electric power steering and no manual gearbox option, how does it stack up to the competition from McLaren and Nissan?
Evo's Jethro Bovingdon attempts to answer that question by pitting the rear-engine Porsche against the mid-engine McLaren MP4-12C on a racetrack and the front-engine, all-wheel-drive Nissan GT-R on some amazing, twisty European back roads. We won't give away the victor of either comparison, but we will say that, in Evo's test, the McLaren's 141-horsepower advantage doesn't give it as much of an edge over the Porsche on a racetrack as one might think, and the lack of a manual gearbox and the inclusion of electric power steering on the GT3 isn't detrimental to enjoying the car on a back road.
Watch the video below to find out which car Bovingdon prefers on road and track - we think you'll be happy to see him drift around turns every chance he gets.

Watch the incredibly complicated operation of Porsche's new targa roof

Despite Porsche having claimed the name, targa tops are nothing new. In addition to the semi-roofless version of the 911, plenty of cars in the past have used removable roof panels - the new Corvette Stingray has one (as have prior generations), and this type of open-air experience has been available on past vehicles like the Pontiac Solstice Coupe and Honda Civic del Sol.
But when Porsche took the top off its brand new 911 Targa here at the Detroit Auto Show, it was indeed cause for pause. Simply put, this is one of the most complicated and intricate electronic roof panel removal techniques we've ever seen, save perhaps, for the setup found on the Japanese-market Civic del Sol from the 1990s.
We won't spoil the video for you, but basically, rather than just the roof panel coming off, the entire rear glass area lifts away the body in order for the small section over the passenger compartment to slide back. This has to be incredibly expensive to repair once it inevitably breaks. And we highly doubt you'll be able to operate this mechanism at any speed.
