Jim, I was wondering about that..the speed limit control. I think the salesman said my Bullitt was "electronically limited" to 151. I know it has some kind of 2 piece driveshaft that's pretty heavy. I've read of those switching to a one piece aftermarket aluminum shaft experiencing vibration at higher speeds.

Jim is correct. Ford reduced the weight of the V6 drive shaft to up the MPG. Once the flaw was discovered, Ford's answer was to put a speed governor on the engine.

It's unlikely to think the drive shaft would fail in such like it did on a Mustang, cause it has a transaxle that is housed in a bigass tube.. No a drive shaft out in the open to a diff like a Mustang has..
944 transaxles typically do not fail in this way they will slowly develop noise from bearings that are failing... Not simply break on ya

And yes they do go 135... I had mine up to 140 mph on the GPS or 147mph on the clock..

The video reminds be of this: (instead of 3, it's 140!)

I had a 2012 Mustang V6 for one week as a rental, the entire car is tuned for MPG. The V6 is a great motor but the automatic gearbox is terrible, it up shifts quickly and lugs the engine at 1200 RPM to maximize MPG. What's the point of a 300 HP RWD convertible that's tuned for MPG and not fun?

C6 corvettes do not have a speed limiter other than lack of HP My car is able to do 186mph in 5th or 6th. It just plain runs out of hp to go faster.

There's a law case from the '60's or 70's that started the speed limiter thing in cars. It seems that there was a Plymouth muscle car that had factory tires on it that some guys got running 135+ mph and crashed when the tires failed at speed.

That's why our cars have odd limits of speed 98 mph for most trucks, 112 is common for sedans 154 for hp sedans.


Cafe standards do have a effect on car safety. lighter, smaller brakes, narrower tires etc.

How fast can a Mustang go?



As fast as you can push it

OR

As fast as the Tow Truck will go....

Is this why you want to sell yours for $75K???

When are you guys going to realize that every car made is not custom made for your ideas of the perfect car? Some people want autos and don't drive everywhere like its the finial race of the season. My wifes 2011 V6 has the auto because she didn't want the manual. Yes sometimes it shifts a little erratic but is not that often or really bad. If it was a problem I would talk to my dealer to see if their is a ecm update. I think it is way to slow to down shift when you step on it, it is a first year for that engine and tranny combo. If I was buying on for myself it would have been a manual tranny, and most likely a 5.0 or gt500. (still thinking about it, after kids are out of college). As it is it is a fun car to drive with enough power to make me think I don't need a 5.0. Our MPG is around 24 driving to town and back, 33 hwy. Lots of fun for the money.

2011 is the ecoboost motor.... TT V6....

If I'm buying a two door sports car, I want a sports car. There was nothing sporty about the Mustang V6 convertible that I had. As I said in my original post it's a damn shame because the V6 is fantastic, it's just mated to a MPG programmed transmission and a soggy suspension. Most imports have managed to master making a car handle AND be comfortable, I'm not sure why Ford can't. I guess you have to get a V8 to get the handling, because by all reports the GT and Boss are great handling cars.

BTW, in case you haven't noticed this is an auto enthusiast website. Do you really think anyone is going to applaud a car that undulates over bumps and drags the door handles on curves?

Matt, I own a 2012, and while it is no BMW, it is a cool car for what it costs. As for the 6 speed transmission, it comes with 2:73 gears that will get you 31 mpg on the highway. However, unlike many other cars, you can order any number of gear sets up to 4:11 as an option. Or for about $300 you can retrofit any gear set you want. Course gas mileage will suffer as you go up the ratios.

You can also order any suspension package you want, from the rental car wallowing pig, to the very stiff Boss suspension. Price is very reasonable.

As for limited top speed? New chip solves that problem.

The bottom line is you get a lot of bang for the buck with a new Mustang. How many V-6's are out there putting out 305 horsepower stock?

Kurt, no arguments on the motor, it's a damn good one. With a proper sports suspension and a manual gearbox I could see it being a very fun little car.

An 08 gt500 will do 140 without breaking a sweat and get there fast enough to turn your britches brown.

A web site Usfra home page has the application forms for either the 130 MPH or 150 MPH Club.
$140.00 and you get an up and back run.
I am seriously thinking of giving the 911 a shot at the 150.
It sucks not being able to dive the car at it's potential on public roads so the
Bonniville Salt Flats are one long days ride for me to get there.
You have to wear a full faced snell/Dot helmet and a couple other safety items.

You get a certificate. I know it is hokey but at least you won't get arrested.
Has anyone gone that route?

Order one with what is called the "mayhem" package, and many of those here who love to slam Mustangs will find themselves wondering why they are having problems staying with a V-6 Mustang.

Here is the "mayhem" package being installed:
