For more of Rennlist's 911 GT3 pictures, check out their other gallery here.

The 991-series Porsche 911 GT3 is expected to make a triumphant debut at the Geneva Motor Show next month, but some preliminary details have snuck onto the web courtesy the Porschephiles at Rennlist. We'd take them with our usual grain of salt...except they also have pictures of what appears to be an undisguised new 911 GT3.

We always love getting our first look at a new car's brochure. The warm smell of the paper, the crisp images and clean text, the neat breakdown of the car's features, options and specifications. Now, the scanned images seen above don't do much in terms of the scent department, but in terms of dishing out imagery and details for the new Porsche 918 Spyder, they're hard to beat.

Infiniti's Emerg-E concept car is the latest in a long line of new product reveals to leak onto the web before its scheduled auto show debut, leading us to wonder: Is it even worth trying to keep a secret in the automotive world anymore?

Update 1: A whole bunch of official press images have, unsurprisingly, leaked onto the web, so we've added them to the slideshow.

Update 2: Mercedes-Benz has released the official details on the new SL-Class, so we've updated this post accordingly.

You can't throw a Hermès purse on Rodeo Drive without hitting a Mercedes-Benz SL-Class. They're like Subarus in New England, F-150s in Texas, or Ferraris in Dubai—it's simply the car everyone owns. So you can bet the collective housewives, debutantes and fresh princes of L.A.'s Platinum Triangle are salivating over these images of the new SL-Class roadster, released in advance of the car's Detroit Auto Show debut next month.
