The horsepower of this car is 340 hp at 7400 rpm .it catch the speed of 60 in just 4.6 second!. Its great, handle great, sound great and was capable of fulfilling every speed-desire in my heart. so is the new porsche cayman gts, with 15 extra horsepower, really worth it?.the gts models have a few added tweaks besides the power bump. they get the sport exhaust, active suspension management and sports chrono standard, as well as some interior tweaks.it has a classic look .if u have this car then u have heaven .its very comfortable . there is lots of space for ur legs . if u have any questions to ask about this car comment it below .and I will surely reply it .thank you
