We're very torn about this one. In Japan, the new 2009 Nissan GT-R's are limited to a top speed of 112 mph (180 km/h). Which, quite frankly, is depressing. Remember though— that's Japan only. American and European hoons are (supposedly) limited to 155 mph (250 km/h). Back in Japan, should you take your Godzilla to a track, the GPS doohickies tell the computer to remove the limiter. Makes sense, right? Limit the car to a moderate top speed on the road, and then unleash its full, city-smashing, Mothra-wrasslin' potential on the track. We have two major problems with that.
