Hello, who can tell me how fast the 350 Z runs without regulation approx.? Is it time to have the regulation removed? The test reports write that the car is locked at 250 km/h. A report even writes that this speed is only reached with difficulty. With a car with 301 hp, I think the acceleration values from over 6 seconds to 100 km/h are not very high. The car is probably very heavy. The BMW 330i with 265 hp has comparable driving performance, despite fas t 40 bhp less.
