Lower cost aside, the new V-6 is almost as powerful as the previous generation’s 4.6-liter V-8, it gets stellar fuel economy and it’s cheaper to insure. Sure, it’s limited to a top speed of 112 miles per hour, but (wink, wink, nudge, nudge) there are ways around that.
The video below, found on Autoblog, shows the potential consequences of exceeding a manufacturer’s design specification. In the case of the Mustang V-6, the car is limited to 112 mph since its lightweight drive shaft is designed more for fuel economy than outright performance.
Remove the electronic governor, and the V-6 Mustang will wind out past 135 miles per hour. Until the drive shaft explodes, that is, sending shrapnel up through the transmission tunnel and into the passenger compartment.
The driver of the Mustang in the video is lucky to be alive and uninjured, especially after ignoring the signs of impending driveline failure. That noise you hear at about 0:34 in? Like the vibration that was surely coming through the floorboard, that’s bad, and not something you should ignore.
We also don’t condone top speed testing on a public road, even a lightly-traveled one. Likewise, when driving at north of 120 miles per hour, we tend to keep both hands on the wheel, instead of one on a camera filming the speedometer.
As the video illustrates, driving is deceptively easy, until something goes wrong.
