Finally, my friend's car has 12xxKM in his Jaguar X type (auto), we decide to do a test run from stand still to 160KM/H. I don't know if my friend's reaction time is bad or what, his car takes off slower than mine (220LB torque VS 156LB torque)! And I keep pull on him till 160KM/H. I did pull like 4-5 cars' length on him (first run without sport mode on), the second run is quite the same, and he turns on the sport mode button (trans gears shifts faster), but the different is not big, I still have him like at least 4 cars....
I don't know what happen to his car, and my friend was so sad yesterday night. Maybe his car still need some times or KM to run in? Or something wrong with his car? I did sat on my friend's car and he floors it, but I didn't feel the car goes fast, or I should say it is slow.... Just like I sat on a Camry V6.... But we will try again once his car reach 3000 KM, so, let see will there be a different or not....
