Max'd my Ram 1500 out at 168km/h, wouldn't go any faster than that. That was on a level road, pedal to the floor. Max speed in any vehicle was 258km/h on my CBR600 while still in 5th gear. Bike was bone stock at the time and I was going up a mountain pass at around 14,000RPM.
On a side note, I have floored my Ram 3500 up to 110km/h just so I can get to the dealership in time to have it repaired.
