Does a 6 cylinder mean you have a faster car?

No a six cylinder does not in anyway mean that you have a faster car. How fast a car is has far too many variables to state that the number of cylinder would be the determining factor. the only way that six cylinders might possibly mean a faster car would be if the motor were by the same manufacturer in the same year and model automobile. Such as if six cylinder were an option as opposed to a four cylinder in say a 2001 ford mustang. Off the line production model would yes be a faster car than the four cylinder, but not faster than the eight cylinder. However after market modifications to the motor could cause a four cylinder to be faster than the six cylinder or the six to be faster than the eight. The most influential factors in determining a faster car would be the horsepower to weight and gear ratios.
