Top speed

According to the Hyundai Veloster twitter page, the top speed of the Turbo is 121mph (I am assuming it is electronically limited, probably due to the rating of tires installed from the factory)

Probably limited in some way. Pretty sure I saw a video out there of a Korean VT going much faster than that (and yes that's with the km/h to mph conversion)

The final drive ratio on this car is very high, and it certainly wont help for a significantly higher top speed. 140mph will probably be the most it is capable of considering the gearing / tire size.

On Twitter, I think yesterday, they said 139mph..
