What did your Ford Fiesta ST replace?

Had a 2005 Subaru Legacy GT that went to 208000 miles. Needed a bunch of stuff done, decided to go with the Fiesta

Mine replaced two cars, neither of which was the right choice for me: (1) a 2002 MINI Cooper with 120K that I'd bought from a friend in early 2016--it was fun and looked great, but had thousands of $$$ of pending repairs and it was, ultimately, a bit frustrating because of its lack of power, and (2) a 2012 Hyundai Veloster with the crappy DCT transmission that was very reliable and well-equipped but a snore to drive. I wanted to consolidate them into one car that combined the best features of the other two and added considerably more performance. The FiST was the perfect solution--more fun than the MINI, more practical as a daily than the Veloster, considerably faster and better handling than either.

Curious as I would consider getting wrx in a few years as a daily and keep the Fiesta for fun. What made you get rid of the WRX?
Rev hang on the stock tune. Like REALLY bad! The stock FiST tune does not have this at all! Don't believe the naysayers, we do not have rev hang. Soft suspension (sti has stiffer) also... *symmetrical awd has to put engine COMPLETELY in front of the drive tires, which makes it nose (pig) heavy, and kinda ruins the handling when at 9/10s. No Android Auto.
Symmetrical awd means tires all have to have identical tread depth or risk grenading the diff... it can get expensive with tires should you have an issue with blowing a tire out. Seats were not comfy for me. I actually prefer the recaros, amazing lower back support. Soft paint that absorbs everything. Not available in a hatch...

Not trying to shit on it, believe it or not. A great car in spite of this. Amazing if you live in a bad weather (snow) climate. I loved the simple interior layout. It had decent power stock, even though 3200lb (as compared to our 2700lb). Amazing resale value (gotta put that into the equation). Also, torque steer... ZERO, nill, nada!

2017 w/Recaros - bone stock

2013 MINI John Cooper Works Hardtop - big fun, but just got tired of it after more than 6 years. Performance of ST is remarkably similar, although handling is a little softer. That’s a fair tradeoff for the ST that cost a third less than a new MINI!

>327k '94 Ford Escort 4 door sedan 1.9L SOHC. The Rusty Reaper forced me to replace it. Drivetrain was still at least 90%.

Our user manual warns against shutting the engine down during a rev... that we wait until it returns to idle RPM. This is to protect the turbo. I've witnessed the hang and it's by design; theoretically to protect the turbo. Get in it HARD and just as it starts to kick in, get off the accelerator and clutch in. I've seen my RPMs start to go down then the ECU immediately revs it back up and hangs it there. It's an incredibly rare occurrence for me. It's never interfered with my driving, has never lasted more than a couple of seconds and isn't a problem to me. I'd rather the ECU do that, than prematurely wear out the bearings on my turbo.

Sorry to disagree with you both, but Rev Hang exists and it is for emissions, not turbo.

----------
Recently, manufacturers have been intentionally implementing rev hang within ECU programming to save themselves from a potential emissions scandal. When the throttle is released and the clutch is dipped, an ECU with rev hang is programmed to leave the throttle slightly more open than usual.

This strategy is used because it was found that suddenly closing the throttle produced a sudden spike in gas pressure within the crankcase which emphasised the rate of oil vaporisation, thus adding to emissions from the engine. Also, when the throttle is suddenly shut, the fuel mixture suddenly becomes lean which creates NOx (oxides of Nitrogen) which also contributes to emissions.

By keeping the throttle open for a small period of time after the pedal had been released, this pressure spike was avoided and cleaner emissions were achieved. Found most prominently in US-spec vehicles to meet the emission rules over the pond, this pre-programming has frustrated many owners since its development. Rev hang can even be found in Subaru’s WRX STI, along with prominent cases in VW and Hyundai products.

To help eradicate this high pressure within the crankcase, a PCV (positive crankcase ventilation ) valve is used which can reduce the need for a rev hang system when fully functioning. This PCV valve is used to regulate the pressure within the crankcase that can fluctuate to high levels when gear changes occur. In internal combustion engines, it is inevitable that a small amount of ‘blow-by’ occurs, which is when gases from the combustion chamber seep past the piston rings and travel down into the crankcase. The job of a PCV valve therefore is to remove a proportion of the blow-by fumes away from the crankcase, thus reducing the amount of high pressure gas contained within.

Although an intentional rev hang system would go a long way in saving your oil levels and help your car sail through an emissions test, most petrolheads only see it as a hindrance to their driving pleasure. With a quick reprogramming of the throttle body control codes and a bit more competence when it comes to checking oil levels, rev hang can be eradicated and your gear changes can be as smooth and as quick as you desire.

Exchange of ideas and information are why we're here so there's no reason to be sorry. It's a good contribution and makes sense. Bottom line, the engineers have good reasons for implementing it. Here's the owner's manual content...

<<Switching Off the Engine............................114
Vehicles With a Turbocharger.........................114
SWITCHING OFF THE ENGINE
Vehicles With a Turbocharger
WARNING
Do not switch the engine off when it
is running at high speed. If you do, the
turbocharger will continue running
after the engine oil pressure has dropped
to zero. This will lead to premature
turbocharger bearing wear.
Release the accelerator pedal. Wait until
the engine has reached idle speed and then
switch it off.>>

Let me clarify: i was not responding to shutting off while rpm is not at idle. That is a no-brainer imho.

I was responding to rev hang doesn't exist despite the nay sayers and rev hang is for the turbo.

Rev hang is for emmisions. The turbo comment was not made by me.

As far as our car, I don't feel any rev hang at all.
However, I was coming off from recently owning a wrx with stock tune, and that thing had rev hang for days... and days. You could take a nap, wake up, and still be waiting for the tach to come down. So, my reference point might be a bit skewed.

In my research, I read and saw videos about the subie. Wow.

I know. Just pointing out where the theory derived. Oil is dual-purpose... lubrication and cooling. Flow rate is necessary for proper cooling.
