The average armored vehicle tends to be a full-size luxury sedan or SUV. For the world's elite - or perhaps those involved in shady underdealings - it makes sense for an armored vehicle to not just be able to ward off bullets or worse but to look like it can as well. Something like a sinister-looking Audi A8 makes perfect sense.

A less likely candidate for a bulletproof vehicle is a low-slung sports car and, more specifically, a Porsche 911. Believe it or not, such a Porsche actually exists. In the video below, we get a closer look at what is literally the strongest 911 on earth. The foundation of this one-off bulletproof Porsche was a 996 Carrera, perhaps the most unloved 911, in part due to its divisive styling.

From the outside, you wouldn't know it was different from any other 996 with its blemish-free Dragonfly Turquoise metallic paintwork. As the narrator shows, it takes knocking your finger against the window glass to reveal that this is no ordinary 911 - the deep sound emanating from each knock is the first sign of this 911's tough construction. An unnamed customer allegedly requested such a vehicle, which led to the armored 911's creation, a car that now resides in the Porsche Museum.

The reinforcements include 20 mm (nearly 0.8-inch) thick glass. The only visible difference is a two-inch black border around the windows that don't appear on the stock 996s. The steel bodywork has been replaced with Dyneema, a high-energy-absorbing composite fiber that is 15 times stronger than steel despite weighing the same.

Porsche conducted tests to gauge the strength of this unique 911's body and says that it can withstand both a 9 mm handgun and a 0.44 Magnum revolver. Naturally, this armored 911 is a heavy beast, weighing in at around 6,000 pounds or more than double that of a normal 996 Carrera. The powerplant hasn't been upgraded, so you'll only have around 300 horsepower to play with from the flat-six engine, which will make quick getaways a challenge.

In the cabin, the major change is the dramatically lower noise levels due to the thick glass. Other than that, it's a typical 996 interior with leather and the other features expected of a high-end sports car. The 996 was followed by the far better 997, but this one-of-one bulletproof prototype is the Porsche you'll want to be inside in a sticky situation.
