Prados which came with 1kz 3.0ltr diesel engine are capable of doing max 175km/hr but the ones with 1kd 3.0ltr (170hp)diesel engine are capable of doing over 200km/hr but their speedos are limited to 180 or 200 depending on from where you've improted it from. Toyota Indus provides 2 different versions of Prado the auto transmission prado has (3.0ltr) 1kz engine in it which is around 125hp while the manual has 3.0ltr 5L-E engine which is around 95-96hp. From the picture that you've posted it seems like its the version with 5L-E engine and with it you'll be lucky if you can touch 175km/hr.
