Mustang Ecoboost Acceleration Issue

[GThunder]

You seem to be missing 4 cylinders.

Poor car. It's only just a baby!

I don't think they give them fresh-off-the-rack cars when they do 0-60 mph or 0-100 km/h tests. Needs time to find its groove.

Octane rating of fuel might also be an issue, as others have said. Weight of driver. Amount of fuel in tank. Grip at launch (I hear these Pirellis can cause a bit of hop). Weather. Presence/absence of space-saver. Etc., etc. But most probably the engine needs to free itself up a little.

Never had a car with sport/track modes, and am even wondering whether you should be going near them until the car's got a couple of 1,000 kms under its belt. Any thoughts on that folks?

As stated above there are a few views on breaking in a new engine.

You would think that the dealer would stress a few points regarding breaking in the engine. (But i guess its in their interest if cars dont last long, they have already been paid)
Especially with the promised 'personalised experience' during delivery,that was sold with the car.

There is a video of a race red mustang in the USA testing out the line lock in the dealer carpark before they guy even drove anywhere!

But he might be planing an engine conversion or something, who knows! Haha

Ill be more than happy to follow breakin methods after waiting so long the the thing to arrive, definitely not in a rush to test 0-100 times!

Id agree with that, waited way too long to have problems. I guess in the usa if you mess the car up you can go down to the dealer and buy another one... Here its another fun 14 month wait! And another winter in baltimore included. No thanks!

There are way too many stories of people over doing it too soon. Slaming into concrete barriers on on-ramps etc because they decide they want to test 'what its got' on a corner for the first time.. Relax! Enjoy/learn the car!

race / sport only changes the sift points to higher RPM and makes steering a little heavier and throttle fly by wire more dynamic and less moderated. Really its the higher RPMs particularly for longer periods that I'd avoid on a brand new engine. New engines have tighter tolerances which is why lighter weight running oils were so popular in older cars. Newer cars with better machining processes we forego running in but we should drive them with a bit of respect until the moving parts wear in and settle (which allows more oil to get between moving parts / reduces friction and theoretically allows the engine to rev more freely)

Hey guys, so I got my ecoboost delivered today and I tried the acceleration timer for 0 - 100 km/h today on a flat/straight road and put the mustang on S mode in the transmission and tested on the sport+ and track modes. I found that I couldn't get it under 8.0 seconds for some reason.. From what I've read they can easily do under 6.0 seconds.

Has anyone else encountered this issue?

Also, what should I do? Can the dealer that delivered it to me help fix this?

Give the motor some 'break in period' first. Surprised that wasn't mentioned to you along the way....

With regards to "run in periods"
What happens to the rental cars and dealer demos when they are in low kilometres :lol:

An 8 second 0-100 ... I'm not sure if that would be about right for the engine not having any boost, but could be a turbo hose fell off, e.g.

We miss out on the boost gauge here, so I guess it's a bit harder to tell if the boost is missing

No doubt probably thrashed within an inch of their lives - specially hire cars.

That's exactly why you stay away from used cars that were part of rental or testing fleets. Carfax will even report this out as a warning.

Oh dear, running in cars, that old chestnut again. Had 4 new vehicles so far, never babied any of them, one was actually run in at Phillip Island race track - never an issue, engine felt stronger then many other vehicles that never saw a redline until they were few months old. Just drive the damn thing, its not 1970's any more.
Fact - some manufacturers actively discourage owners from taking it easy with new vehicles. Worst thing then hitting a redline is to run it at a constant low revs.

I dont know where you heard of manufacturers 'discouraging' taking it easy to start with.

I will agree that the term 'break in' may mean a slightly different/ less critcal thing than it used to years ago, but I have never heard of anyone encouraging putting a new engine under high stress straight up.
Testing the 0-100 times on day one is not something I would suggest, nor have I ever had it suggested that its a good idea.

Yes the modern term 'breakin' might not be as important as it used to be for engines... Ill agree that the engine should not be run constantly at low ('low') revs. Revs should be varied (read not 100% throttle runs straight out of the dealer carpark) .

Its information like the above that make less experienced people think they can test the 0-100 straight up, and expect no ill effects. Running in a car 'at philip island' doesnt really mean much, as the way you drive it does not necessarily mean you are beating on the thing. If you want to try and beat the track record on day one thats your choice, pretty sure its not recommended by any manufacturer though. And I definitely have not heard anything like that out of Ford regarding the Mustang.

Here is a thread with some views:

This is copy paste from the owners manual.

BREAKING-IN
You need to break in new tires for
approximately 300 miles (480
kilometers). During this time, your vehicle
may exhibit some unusual driving
characteristics.
Avoid driving too fast during the first 1000
miles (1600 kilometers). Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Do not tow during the first 1000 miles
(1600 kilometers).

Link to owners Manual. (Breaking-in information is on page 191)

Loosely relevant to this thread.... some comments earlier regarding traction control etc....

While you dont 'need' to keep it on .... it could be a good idea for a while to start with at least !:doh:

Clearly not in Australia... the dash cam driver didnt say a thing!:lol:
