Heads up... your 2011 Mustang V6 will explode at 135mph

I had an opportunity to drive my Mustang on a closed road at high speeds and this is what happened. Apparently the standard tires are not the only reason for the car being limited to such a sub performance speed of 113MPH. (Even slower then Ford's Fiesta and Focus models = 118MPH) My stock driveshaft failed at about 135MPH, so if these cars are run flat out in the real world without the ridiculous speed governor to keep them together, the drivetrain is not actually designed to handle the power of the engine. Major damage caused by the broken shaft included a hole in the metal floorpan, major exhaust system and muffler damage, broken transmission shifter, broken parking brake, broken interior plastic trim parts, etc. My 1997 Mustang Cobra could run 152MPH for unlimited time periods and this new car only held together for about 15 seconds under full throttle!!! Give me a break!!! The drivetrain is a REALLY BAD place to cut costs for a net profit $, especially on a 305HP Mustang! I really hope that Ford makes a change to the V6 drivetrain for 2013. After all, many of these cars are driven regularly on the German Autobahn and a failure like this could be very dangerous! Solution = Ditch the governor and install a decent driveshaft! Even a 23K Honda Civic can go 137MPH without breaking!!! Come on!!! This is my 5'th Mustang and my 1'st major failure. This is totally unacceptable for a performance car!

That's a really bad assumption considering most people buy the V6 as a "sporty" fuel efficient commuter car. Added weight to the driveline can sway a consumers decision to buy a one more MPG Hyundai.
 
while Ford opted to give both the V6 and Mustang GT’s the same rear end and transmission…they did not give them the same driveshafts. Perhaps because they wanted to reach that magic 31 mpg mark in the V6 cars.

hmmm
 
well i think that Ford missed the ball on giving the V6 a weaker drive shaft than the GT.

BUT... look at the 03-04 cobras for example.... those things snapped half shafts all the time with light mods or more than normal abuse.

things like this happen all the time. you tune or flash the PCM or add a ton of go-fast parts, you are bound to start breaking the weak link... whether it be in the driveline, trans, or engine.
