Undercover cop cars: apparently they work best when everybody knows about them.

This is a Nissan GT-R that's been converted into an undercover cop car. Presumably to infiltrate the Fast n' Furious movie franchise and put a stop to it but possibly just because F*** YOUR TAX DOLLARS, SON -- the chief and I are going joyriding.

With its four wheel drive and computer aided everything, Nissan claims that the 2012 GT-R can sprint from zero to 60 mph in just 2.9 seconds, so the cops won't exactly need to upgrade it in order to catch anything short of a Bugatti Veyron.

The police modifications are being installed by by EVI, a Northern Virginia company that supplies vehicles to forces in Virginia and the Washington DC area, but they won't say who it's for.

So, yeah -- if you see a black GT-R being driven around DC by a guy with a fake beard and mustache, chances are good it's an undercover cop trying to break up street-racing gangs or whatever. But you know how you can find out for sure? Offer to sell him drugs. If he says, "PUT YOUR HANDS ON THE HOOD, YOU'RE UNDER ARREST!" it's probably the cop.

Hit the jump for a couple more shots of the vroom-vrooms.

Don't even try to outrun this undercover cop supercar [dvice]

Thanks to Davey, who agrees they might as well have had a f***ing KITT replica made.
