New Porsche and Lamborghini for Paris Motor Show

The silly season is upon us now, and teaser images from Porsche and Lamborghini have been setting the Internet alight... despite not actually revealing anything at all.

Lamborghini's surprise unveil

Although the upcoming Panamerica is the worst-kept secret in the industry, the arrival of a new Lamborghini has caught the media off-guard. The solitary teaser image, which shows a portion of the rear diffuser, reveals nothing about the new car, and the speculation about what it actually is has already started in earnest.

Our money's on another Reventon-style limited volume model...

Porsche Panamerica

The cunningly cropped image of the Panamerica - a four-door BMW M5 rivalling Porsche - gives little away about the styling of the new car. Except, perhaps, that it could be any other model in the range, from the Cayman to the 911GT2.

It will be unveiled at next month's Paris Motor Show, and we'll be there..
