We're just days away from the official unveiling of the 2013 SRT Viper, so the brand is ramping up their teaser campaign by releasing another image of the American supercar.

The latest picture is the most revealing image we've seen and it shows the car will have a double-bubble roof, a ventilated hood and curvaceous styling.

Inside, the cabin will have an evolutionary design with a leather-wrapped dashboard, metallic trim and a wide center console.

Specifications remain a mystery, but speculation suggests the car could have an 8.7-liter V10 engine with more than 600 hp (450 kW / 608 PS) and 560 lb-ft (760 Nm) of torque.

Just moments ago we posted a speculative rendering of the Viper roadster version.
