Fiesta ST vs Focus ST: Which Hot Hatch is Actually Better?

The Fiesta ST and Focus ST have been hyped up by automotive journalists since they came. We praise the Fiesta ST, in particular for being one of the most fun hot hatches ever.

The Focus ST is also fun, but with a slightly more grown-up attitude. If you’re in the market for a hot hatch, but can’t decide between the two, you’re not alone. In this short article, we will help you decide which one is better for you.


Ford equipped the Fiesta ST with a 1.6L engine paired with a KP39 turbocharger from Borg Warner. This tiny little turbocharger will produce around 21psi of boost which is actually quite a lot for a production car.

This allows the Fiesta ST to produce a claimed 197 horsepower and 202 lb-ft. Dyno tests prove the Fiesta ST actually produces closer to 250 lb-ft of torque.

The Focus ST, on the other hand, is equipped with a 2.0L engine paired with a K03 turbocharger which is also from Borg Warner. The turbocharger is small compared to other 2.0T engines, but larger than the KP39.T

hat K03 turbocharger produces about 16psi of boost, but many owners report closer to 19psi. This allows the Focus ST to produce 250 horsepower and 250 lb-ft.

Ford uses these tiny turbochargers for a reason: low-end torque. These tiny little turbos make max boost at a very low RPM which makes the car feel much faster than it actually is.

For the Fiesta ST, with a tune installed we regularly saw 23+ at 2,200 RPM. The larger turbocharger on the Focus ST has room for increasing boost, whereas the Fiesta ST turbocharger is pretty close to the limits from the factory.

Both turbochargers struggle to make top-end power when pushed to the limits. This is caused by an inability to maintain boost levels at high RPM. Not only does the boost taper off from 20+ psi down to 10-15psi, but the charge air temperatures at that point are insanely high.

High charge air temperatures mean less ignition advance and more detonation – yikes!

This next part is very subjective so don’t take it too seriously! Both the Focus ST and the Fiesta ST share the same “sea creature” looking front end. It’s kind of what Mazda does with the Speed3, but the big smiley face on the front end is flipped upside down.

The Focus ST received a face-lifted front end which arguably improved the looks.

They both look really good, but from the rear, the Fiesta ST looks a little odd. The Fiesta is a fairly tall and narrow vehicle whereas the Focus is much wider. We think the Fiesta ST looks a little angrier, but the Focus ST looks much more like a sports car.

We will leave this one as a tie because which one looks better is completely up to you.

The interior is where you send all your time driving the car (obviously). They base both cars on cheap economy cars, in fact, the standard Focus is one of the worst valued vehicles on the market based on resale value.

If you’re expecting a super nice interior from either of these vehicles you’re in for a surprise.

The Focus ST is spacious and comfortable. The materials used are average including some hard plastics, but that’s being expected considering it’s based on an “econobox”.

Overall, the Focus ST actually has a decent interior, but it’s nothing to write home about. The trunk space is awesome thanks to the hatchback nature of the vehicle. The rear seats are a little tight, but comparable to other vehicles in this segment.

Unfortunately, the Fiesta ST is awful regarding interior quality. They make pretty much everything out of a hard plastic with a weird texture on it. It’s better than some other vehicles in this price range, but it‘s nothing to get excited about.

The buttons are cheap; the materials are cheap, and it looks pretty boring on the inside. The rear seats are pretty small, but that is to be expected in a vehicle this small. Trunk space is also relatively limited, something which you should expect in a vehicle this small.

You may actually have to sit in a Focus ST and a Fiesta ST to really see the difference in the interior, but the Focus ST interior is WAY nicer.

Ride Quality

If you’re expecting a smooth ride out of either of these cars you’re in for quite a surprise. To achieve the level on handling Ford has with these little front-drive hatchbacks the suspension must be very stiff.

The Fiesta ST has a much firmer ride than the Focus ST, but that’s not to say that the Focus ST isn’t very stiff as well. Both are much softer than the Focus RS which is unbelievably stiff.

I would recommend taking a ride in a Focus ST. If you find the Focus ST to be annoyingly stiff than the much stiffer Fiesta ST is definitely out of the cards. Interestingly enough, many owners report improved ride quality after installing aftermarket suspension.

The stock damping setup leads to a rather bouncy ride which can be solved with quality dampers.

Purchasing Price

It shouldn’t really surprise you that the Fiesta ST is cheaper to buy than the Focus ST. It makes less power and is based on a $13k car. Prices vary greatly from place to place, but you can buy a Fiesta ST from the dealership for around $20k depending on the options and if Ford has any sales going on.

The Focus ST will hover around $25k, once again this really depends on the options and if Ford is having any big sales going on.

On the used market both are significantly cheaper, but the Fiesta ST is almost always a few thousand dollars cheaper than the Focus ST. I purchased my 2015 Fiesta ST with 25k miles for $21k including all taxes and fees plus an extended warranty.

Fun to Drive

The single biggest reason anyone should buy one of these cars is how they drive. Neither of these cars are particularly fast on paper, but they both feel like little rocket ships. Ford specifically designed both of these cars for canyon and autocross driving.

If you’re planning on buying one of these for driving in a straight line, you should really look elsewhere.

The Focus ST is faster on the typical canyon road and the autocross. I have tested this and the Focus will almost always come out on top. The wider track and larger engine really help it dominate the autocross.

The proper independent rear suspension gives the Focus ST a massive advantage when driving at the limit. However, to some, it doesn’t “feel” that fast which is fairly hard to even explain.

It’s definitely fast enough to get you in trouble on the street, but sometimes it doesn’t feel like it. A car that “feels” fast will always be more fun than a car that is fast.

Throwing the Focus ST into a corner will result in some lift-off over steer which is something you want in a FWD car. This helps to mitigate under-steer which FWD cars inherently struggle with.

The wider track and wider tires definitely help with this issue, but the brake vectoring system is what really makes all this magic happen.

The Fiesta ST, on the other hand, is definitely slower on big canyon roads. On super tight and technical canyon roads it can actually pull ahead due to its much smaller size. In fact, on my local twisty canyon road, no vehicle was able to outrun my Fiesta ST (Including a Viper ACR, BRZ, Veloster Turbo, 350Z, etc).

The narrow width and tall height do limit it on big racetracks. Some people have even reported flipping their Fiesta ST if they bump a curb hard enough on a track, but that has only happened a few times.

The Fiesta ST’s tiny turbocharger give it a super hard punch when pulling out of corners, making it feel incredibly fast. Plus the smaller size, shorter gears, and stiffer suspension make everything feel even faster.

Once again the brake vectoring system is what really lets this little car shine on a canyon road.

Here’s the point I’m trying to get to: the Focus ST is faster, but the Fiesta ST is way more fun. Seriously, hop on an ST forum and almost everyone will tell you the same exact thing.

Matt Farah from The Smoking Tire even compared the Fiesta ST to a BMW M3 saying the Fiesta ST just feels way faster, but in reality it isn’t.

Fiesta ST: 2


To summarize all this information, there a couple key points to remember. The Focus ST has a nicer interior, smoother ride, and is faster. The Focus is really a better car for the average person.F

or those of us who want to most manic and fun car possible the Fiesta ST is a clear choice. It’s small size and punchy engine makes it feel way faster than a Focus ST while actually being slower.

  1. Having owned both I can say I love the Fiesta ST better. I do’t find the ride bad at all. The interior however, compared with my Focus ST(3) is awful. I felt the Focus ST was a handful on mountain roads, and at some points downright scary. The Fiesta ST is a dream. Yes it could be faster but that’s ok. It feels fast enough! Plus, better mpg.

  2. You say that the Fiesta manages the same torque as the Focus from less displacement, but it loses the engine comparison? The Focus is also known to struggle putting all that torque to use, even with much wider tires, a complaint rarely leveled at the Fiesta. Maybe its because the turbo is ‘maxed out” on the Fiesta? Cobb and Mountune would beg to differ with that, with many plug-in options available to boost power on the stock turbo.

    The Focus motor can be a beast no doubt (see the RS) but stock for stock, the Fiesta is the winner under the hood.

  3. fiesta is way more of a drivers car…focus is the real grocery getter…leave canyons to the fist.add a tune and upper and lower front bracing to pass race bikes in angeles crest.

  4. I have owned my 2018 Ford Fiesta ST for four months now and I love this car, it has one mod done to it I opened up the closed off intake so it gets fresh air going to the turbocharger now and it really made a big difference in the way it runs compared to it before it would heat sink the incoming air and lose power until it cooled off now it stays the same all the time around 86 degrees on the intake side even in stop and go traffic. I run 93 octane shell gas and or 87 octane with boost making my own 94 octane with the boost I am running lucas 3X the boost treats 25 gallons so half the bottle on fill ups with the cheaper 87 octane runs just as good with the boost as normal 93 octane does without boost. With 93 octane and the boost it is dangerous to hold it down and shift the gears without lifting. This is the best thing you can do to a new Fiesta ST and it is free and only cost you five moments of time opening up the inlet so it breaths fresh outside air all the time. Ford must have done this for people that live in heavy rain snow weather. All I did was pull the rubber seal out of the connection just in front were it snaps together on the plastic intake tubing area. It is hid and you can not even see that anything was done to it so another nice touch to say the least. I would have to say maybe 8 hp and 9 ft lb’s torque increase. I choose the color magnetic with charcoal black interior. With two options I had to have the navigation and the moon-roof $1500.00 dollar options for both.The payments are $412.63 for 74 months. Traded in a 16 Focus with 11000 miles on it they paid it off and sent me a check for $533.00 dollars extra for my trade in. I miss those payments with 0% interest 227.00 a month these are almost double but I really do love my new Fiesta ST.
