Ever since Mercedes-AMG revealed the GT, Prior Design has been in a constant state of innovation trying to better an already exceptional machine. Numerous Prior Design body-kits and additions found their way onto the sexy body of the AMG GT with the last one revealed only days ago. Called the PD700 GTR, one would think that Prior Design worked on the engine and uprated the 4.0-liter, V-8 to 700 horsepower, however, they did not disclose any information confirming this. Considering the fact that Prior gave similar names to a number of its body-kits and they did not actually uprate the power of the engine, I will say that this cool widebody monster uses the same 522 horsepower, 4.0-liter as the stock car. Nothing wrong there.
