Sleeper cars are super fun. They look like normal, mundane, and generic cars yet pack hundreds upon hundreds more horsepower under the hood. In the case of this Nissan Altima, it is a generic car, but NOT a sleeper. This Altima has been completely gutted to save weight, been outfitted with an ultra strong roll cage, and has a high tuned version of the motor found in the Nissan GTR. Best part, it is completely rear wheel driven and makes 1,300 horsepower!

Below is a short video on this super modified Altima compared with a 900 horsepower Subaru STI!
