Not sure about acceleration. It may be 10 seconds or more from 0 to 100/62. Remember, these trucks are not built for speed.
Regarding top speed, 180 km/h (112 mi/h) is possible but the engine's ECU shuts it down. Possible but not recommended, unless you are in for a serious accident. Furthermore, in any 70 Series model, above 85 km/h (53 mi/h) you are wasting fuel because of the body's not-so-aerodynamic design.
