The meanest Cobra Jet quarter mile monster ever created is alive - and Leftlane has the spy shots to prove it.

Ford has so many Mustang variations roaming around its stable these days its all but impossible to remember them all. But one thing is for sure, after seeing and hearing this particular Mustang, it would be impossible to forget!

For years Ford has offered a factory-produced dragstrip machine in the form of the Mustang Cobra Jet. Complete with slicks out back, skinnies up front and a whole lot of power, this is a purpose-built machine without any doubt. Today, we have images of the most radical looking Cobra Jet we've ever seen.

It takes just but a glance to notice the absolutely ridiculous ram air hood. Look a second more and you will notice the massive drag slicks stuffed in the rear wheel wells, while the "just enough" skinnies are providing steering in the front.

Underneath, one will notice special exhaust tips that dump just behind the front wheel wells, while a GT500 front fascia appears to complete the outward appearance changes from a standard Mustang GT.

For 2012, the Cobra Jet featured a 5.4-liter supercharged engine based on the 2011 SVT Mustang with two supercharger options, either a 2.3-liter TVS unit or a 4.0-liter Ford Racing Whipple supercharger. The 2012 model also came with an aluminum block engine, standard automatic transmission, double keyed crankshaft, Manley H-beam connecting rods, low-drag racing brakes and optimized spring rates for the front and rear.

With the previous model offering such a list of modifications, it begs the question: what's under the hood and body of this new black prototype Cobra Jet?
