The Dodge Viper and the Ford GT have always had a pretty stout rivalry. Even when the GT was still in pre-production, people were already calling it a “Viper killer”. When the GT went into production in 2005 the two cars’ stats were constantly compared to each other. It’s easy to see why; they are both American made, have a curb weight of around 3,300 pounds, make a ton of power, and cost a whole lot of money.

The Ford GT pulls out the win over the Viper hitting a top speed of 167.6 MPH versus the Viper's 164.7 MPH.
According to the video description, the GT actually has about 1,100 horsepower coming from its boosted 5.4L, and that extra 100 horsepower does come in handy. The GT manages to edge out the yellow 2nd Gen Viper in a close race, with each car hitting top speeds of well over 160 MPH.
