According to the current mot, the Nissan Z 350 super sports car has brought 20 hp less on the test bench than Nissan officially claimed. Are the Japanese or are the engines not so good after all? So far it should have happened that a car has more hp than indicated, maybe Nissan wanted to show that Japanese manufacturers can also play the role of innovator. No, joke aside: how can such a thing happen and is it a change reason? mfg
