That type make sense to me, they are usually maxed at whatever tire they come with is rated at. Our Dodge Journey would go 118 easily where it hit the limiter. The Durango R/T we got next would also only run 118 lol. We replaced the Durango when it got worth what we paid for it and bought a grand Cherokee, I haven't top speed tested it yet but I am sure it is the same as the Durango and Journey due to tire ratings. I imagine most cars and SUVs today could run 140-150 but they save tons of money by only putting 118mph tires on them. There is plenty of people that don't need to have the ability to go that fast as well!
