The Nissan GT-R police car is a modified GT-R designed for undercover police work. The car has been modified with lights and sirens that stay hidden until activated. The car was created by EVI (Emergency Vehicle Installation), a company known for customizing police cruisers and other law enforcement vehicles.
The Nissan GT-R is famous for being both incredibly fast (0 to 60 in 2.9 seconds) and incredibly affordable by supercar standards (under $100,000). The GT-R featured here is an unmodified version of the original. The car still only has two seats and still has a monstrous 530 horsepower V6 engine. The Nissan GT-R police car was made an American law enforcement agency that has chosen to rename anonymous. You can check out images of this badass cop car, along with video, here.
