That's a difficult question to answer, but it's probably faster than your car.
Since there seems to be a new European record for the fastest GT-R about once every few days, we're not going to say for certain that this is the fastest GT-R on the continent, despite the tuner's claim. But it certainly is one hell of a quick car. It was built as a group effort between techs from Greece and Romania for Exelixis Motorsports in Romania. The car has 1,500 horsepower under the hood, and can run the quarter mile in 8.47 seconds, with an exit speed of 172.2mph.
Though there might be some people who wish to know once and for all which is Europe's fastest GT-R, we think it's fantastic that the competition is so intense as to make it nearly impossible to tell.
