397km/h (246.68mph) in my lamborghini murcielago it cant go any faster in free roam mode, ill try drag later and see how fast it can get
*edit* ive tried dragging with my murcielago and it still cuts out at 397km/h. ive also tried other cars (carrerra gt, cayman, slr, corvette) and none of them can surpass 395km/h so i dont know how anyone can get 407km/h(253mph)
It said on some FAQ that the Acura RSX can go beyond 250mph with some trick which you'll have to do in precise order.
Also, when you change the gear ratios it tells you the estimated top speed, but I don't know whether if that's reliable or not.
Maybe we can have a MW civilian cars (from challenge series) record category?
136mph - pizza delivery car
150mph - pickup truck
144mph - minivan
143mph - taxi
Mine best in U2 is 256 mph with skyline. Here's video:Click!
In MW which I didn't play much is about 380 km/h by Carrera, It's quite time so I'm not sure what is the exact number.
NFSU2, Toyota Corolla GT-S, 212mph. after few online runs around the outer rim of the city i got few messages from pissed off noobs who had lost to me in their GT-R's and Supras.. hachiroku FTW!
