Ford Focus 1.0-litre EcoBoost

We get behind the wheel of the all-new, three-cylinder Ford Focus EcoBoost


Does less mean more? In the case of this three-cylinder engine, there's certainly a case to be made. While the Focus is one of Britain's finest family cars, we expected the 1.0-litre EcoBoost to be a damp squib. We were wrong. It's an exciting and well engineered engine with more than acceptable performance and very good economy, as long as you have a gentle right foot. Our main concern is that at almost £18,000 in turbo form in this most popular Zetec model, it is expensive.
We've become used to the warble and whirr of a tiny three-cylinder engine in city cars such as the Toyota Aygo, Citroen C1 and Peugeot 107, but is Ford's decision to fit its all-new, 1.0-litre triple into its best-selling Focus a step too far? We travelled to Spain to find out.

More than 200 engineers based in Dunton, Essex, have worked on this little engine, and their painstaking development shows. The iron-block, aluminium-cylinder head unit has several innovations, including three tiny pistons with four valves per cylinder, direct fuel injection, a minute turbocharger (from German firm Continental) and a maintenance-free, oil-lubricated camshaft drivebelt. It only weighs 97kg with its ancillaries, and is so tiny that the block is no wider than an A4 sheet of paper.

It's available in two power outputs; 98bhp with a five-speed gearbox, or 123bhp and a six-speed gearbox. Ford says it is working on a twin-clutch semi automatic for the unit, too. The official fuel economy figure for the 123bhp unit is 56.5mpg.

But why is this engine in the Focus first, when the Fiesta seems the more logical recipient? Ford's petrol engine chief engineer Andrew Fraser explained that the three-cylinder is designed to replace the ageing 1.6-litre petrol unit, which makes up a tiny percentage of Fiesta sales, but about 15 to 20 per cent of Focus sales. The new three-cylinder is available in base Focus Edge trim for £16,245 with the 98bhp engine, but the most popular model is likely to be this Zetec car with 123bhp, priced at £17,745.

Under the bonnet, the engine looks pretty small, although with all the engine ancillaries and pumps at the front of the block, it fills the available space. Start it up, and there's a funny squirrelly noise from the starter motor, but then an almost silent idle. You would be hard pressed to tell how many cylinders are pumping up and down. That remains the abiding impression on the move, as Ford has elected to damp down the warbling signature tune of a three-cylinder. This is fine and good, except when you do hear the whirring engine on part throttle openings, it comes as a complete surprise. Another surprise is the amount of torque available, especially around 3,000-4,000rpm, where the unit feels lively and strong. 

However, hills, speed and heavy loads show up the engine's relative lack of torque (although the turbo will over boost from 170 to 200Nm for 30 seconds) and drag the performance down. Overtaking, pulling out of sharp turns, or climbing steep hills often require a couple of down changes, although the engine makes no complaints and happily revs to its 6,500rpm red line. The all-new six-speed gearbox is a gem, too, with finely tuned ratios (less than 2,500rpm at 70mph in sixth gear) and a fluid-feeling gearshift.

With 30kg less in the nose, the Focus feels incredibly light. The handling is much improved over the 1.6-litre petrol, with better turn-in to corners and a supple, comfortable ride. Braking, too, feels more positive, with less nose dive as you apply the anchors. Above all the Focus is really quiet and refined. Lift off the accelerator, and with less engine braking than the four-cylinder units, the Focus simply keeps rolling.

Add in Ford's well-proven cabin design, safety features such as lane-departure warning, City-Stop braking, and useful options like the new active door-edge protectors, Quick Clear windscreen and active parking, and you'll wonder if Britain's favourite family hatchback hasn't just got a bit more appealing in every way.

What about MPG ???

Hi @ creoulo - the official figure is 56.5mpg (all the figures are in the 'at a glance' box on the right). To quote the verdict: "It's an exciting and well engineered engine with more than acceptable performance and very good economy, as long as you have a gentle right foot."

This is the first drive, so we weren't able to carry out our own economy tests. But we will be getting the car into the office for a longer test as soon as possible.

Auto Express

I think Ford should make a version for the Fiesta as soon as possible.
If they can tune the engine to sub 100g/Km Co2 emissions, the Fiesta would then be road tax free and also exempt from the London Congestion Charge - which, I believe, would vastly increase the Fiesta's sales appeal.

Ford finally caught up with groundbreaking 1980's 1.0 turbo's technology, wow groundbreaking stuff? This is crap news, can't "feel the difference" . 3 cylinder 1.0-litre turbos were around in the 80"s whats new in that?

Dagenhams produce more state of the art diesels but employing just 1,800 will never be the same as 50,000 during those British made Fiesta Cortina & Escort whole car assembly days.

Toyotas Deeside plant has produced millions of UK assembled engines + Avensis & Auris whole car assembly lines as well. I would like to "feel the difference" and buy at least 1 British assembled Ford car. Toyota have assembled 1.5 million UK made cars in the last 10 years Ford have assembled none.

Ford need to "Go Further" and produce more than least 1 car per year in UK.

Great technology, great future for Ford. Some comments are very stupid. Sorry.

I don't want to fall into the trap I sometime accuse others of doing in commenting about vehicles I have no experience of but would refer to a former colleague who bought a new petrol three cylinder VW Polo. He disliked this car as it this "vibrated through the pedals" and it was disposed of very quickly indeed.

According to an engineer friend of mine the three cylinder arrangement is inherently unbalanced and prone to such problems. Presumably with age a three cylinder power unit will only get more vibratory.

Are manufacturers conducting a cynical, cost cutting, exercise relying for sales on the tightness of new construction and the "thwoar" reaction of excitable motoring journalists to anything with an exhaust note perceived as "fruity"?

Compared to Fiats Air engines this is pretty poor.

Nevermind BMW's petrol and diesel technology.

It's a pity ford just don't have the ability.

I just don't get it, 56.5mpg is not that good, Fiat 500 (ok it's a bit smaller) acheives 69mpg, Kia have a 79mpg car. My VW Passat Estate delivers more than that (in diesel guise), in fact all of Ford's own diesels acheive better mpg. The problem with putting a 3cylinder engine in a bigger car is that the engine just lacks overall torque, it's much better match with a smaller car.
I agree with Ivorbiggen, Daihatsu ran 3 cylinder little cars back in the 80's, they sounded like sewing machines, and don't forget the Daihatsu Charade GTTI, that was one very quick 3cylinder car.

I'm sorry, but the above comments just make me laugh. Unless you have driven the car over an appreciable distance, say 200 miles, or atleast 100, on different roads, and filled up with petrol afterwards, you are in no position to comment on how good the car is/isn't. Yes there have been previous 3 cylinder cars, but I would like to think that technology has moved on. And whats the point comparing diesel against petrol when there is a premium to pay for diesel, plus with this car, you don't even get the tax benefits you got with previous models???

I am impressed with the economy figures, and I am much rather concerned by the real world figures rather than those quoted, especially unfair when comparing cars of a different class.

I haven't even sat in the new Focus, so cannot comment on the car in any way, but nevertheless I certainly wouldn't talk it down. Personally, as a second hand car it would be good, for me, the RRP is a bit too high. Yes it makes sense in the Fiesta as well, and it might make its way down to the Ka (99bhp version) in all eventuality as well.

Rant over :)

All the talk about 3 pots of the past really misses the point. This is a clean sheet design, intended to reduce vibration and noise as a priority. I agree the VW 3 pot is awful, and the Japanese did turbo 3 pots years ago. But this Ford unit is new and interesting. Google what Ford have done to engineer this unit, it's very clever stuff, and totally original.

It has the potential to steal sales from the 1.6 TDCI IMHO, especially for owners doing mainly short runs.

Why does Autoexpress talk about the "relative lack of torque". The 1.0 Ecoboost ranges from 170-200 Nm, from as low as 1300rpm!!! The comparable 1.6 Duratec TiVCT (the engine this replaces) only produces 160 Nm peak at 4300 rpm (and 120 bhp).

In every way, the 1.0 Ecoboost wipes the floor with the old 1.6 petrol. No question. Torque, it ain't lacking. Nor power, or refinement. It's an improvement in every single way, even if in the real world the economy is much the same, which I doubt.

Your right Oilburner. Proper car magazines that have also published tests of the new Focus today suggest the Engine pulls strongly throughout the rev range with none of problems reported by the Sun - sorry Autoexpress

Abig car like Ford Focus 1000 cc engine handles this vehicle with almost 200 NM and 56.6mpg hat does not uses diesel is a really good work after the technology from Mazda1.3 liter SKYACTIV-G unit comes with 84 PS/62 kW and 155 Nm of torque and features a remarkable consumption rating of just 3.3 liters/100 km (71.2 mpg US / 85.6 mpg UK)

Lets face it guys, this car is for daily commute from point A-B for economy. If you want performance go buy the big-arse turbo version to the Focus. The power figures are great and adequate when you think that the mighty Cortina GXL king of the roads in the 70s was only 89 HP. I have yet to see a 3 cylinder engine that I like, but you can bet Ford is going to sell a heck of a lot of these because the car cabin is full size, has adequate power, and sips on Petrol. Well done Ford.

Cant see a 3-pot turbo engine pulling a Focus lasting very long whats the projected lifespan of these crap engines.

Prefer a bigger better Econetic 1.6 that will run for three times the mileage before the engine becomes worn clapped out, the 56 MPG Ecoboost the tiny 1-litre engine produces returns is piss poor for such a small engine.

Would love to get hold of a 2 litre ecoboost engine thats fitted in the RWD Ford Falcon and adapt it to fit into a king of the road Mk1 Cortina that would be real fun car to drive a real blast. Focus styling bores me to tears puts me right off of buying a Ford, the Cortina Mk1 Lotus Cortina was pure magic.

1. None of you have driven this car.
2. All of the reports from all the rags seem to be singing the same notes.
3. Not many cars mpg figures match real-world driving, one way or the other. Jury is out, hope is high.
4. This looks to be quite an engineering achievement regardless of whether you like the Focus or not. What in the hell is wrong with that?
5. I would wager nobody who has commented would have the chops to even be considered on the team that developed this. So, clamp it.

There is little doubt it will end up in the Fiesta, and I really don't think people who do spring for this will be disappointed in the least. It will get great mileage (whatever that looks like), helps the car handle better and provides a more refined experience. Geezus, do you need the thing to suck your toes, too? Give these guys some props.

I agree with much of this comment, save for the fierceness with which it is expressed!

However be very cautious about journalistic over-enthusiasm, or over-criticism for that matter. Recently I have travelled in a couple of vehicles which, from the passenger's point of view, were completely at variance with their reviews both better and worse.

My caution about three cylinder power plants stems entirely from a cynical "we have all been here before" point of view. Some brave souls will have to be the guinea pigs to see if the new power unit does wear well.


Oh look more Bigot comments blah blah, all you haters have never driven Fords new Ecoboost so stop slagging it off.
Yes its 3 cylinder, but I think technology has moved on a little from the 80's and I would suspect engineers have fully tried and tested the idea before risking putting it in such a well loved product. Oh but no... its shit, end of. I'm sure based on these comments Ford are shitting themselves, I think not. As with all products, proof is in the pudding, and until you have driven one, don't come on try to tell the public its rubbish.

Of course all of this is pure conjecture, before either the doubting "bigots" or the enthusiastic "phwoar" brigade have sampled the power unit concerned. The pros and antis seem fairly balanced but the real issue is whether the motor will remain similarly balanced after thirty or forty thousand miles in the hands of poor or mediocre drivers.

We are living in exciting times thanks in part to EU emission rules which are forcing car makers to clean up their act.
A 1L engine in a Focus size car sounds incredible. Most testers however report that it does not strain shifting the car's weight. That it is smoother than the 1.6L and has a better power delivery.
Amazing as it sounds I hope it works well in the long run.
It's great to have an internal combustion engine that is so clean, so powerful and versatile. However I can't help feeling that it's time for car giants to pump serious cash in developing ultra efficient hybrids.
Come on Ford and VW. Toyota did that 10 years ago. And Chevrolet has taken it a step ahead with Volt and Ampera.

Come on aerolus Ford were producing diesel engines that produced 65 MPG back in the 1980's for the Orion, Escort & Fiesta from 4 pot 1.6 litre diesel engines.

56 MPG is total crap all Ford have done is fit a turbo to a piss pot engine won't wear well, to all you ecoboost know-alls posting here what is the projected life of the engine in terms of milage, will it be totally clapped out when a econetic Ford diesel power plant is only just run in?

Knowing how crap Ford carbon core ignition leads are, it will be a licence for Ford dealerships to print money when you turn up with it sounding like a bag of bolts have just been dropped in the sump or it won't start.

Fadyady you must be a Septic Tank nobody in austere UK can afford to buy a God damm awful Prius what planet do you live on the USA or Japan are the only two countries where it is made and the only two countries where folk like it, buy it, Nobody buys them in the UK they have averaged just 100 sales a month in the UK in the last 10 years, they said the price of hybrid prices would come down 10 years ago, ten years later the Prius still is very just as expensive and a much much cheaper to buy diesel will return much better MPG, and a owner won't need expensive battery replacements that cost of which would keep running you on free diesel for quite a few years, also the diesel engine will only just run in when the Prius petrol engine will be spluttering to start because its clapped out.

Cars, are products...which means that final deal is closed on the counter.

The 1.0 3 cyl ecoboost is a great way to make the focus lighter more economical on the run and cheaper to buy than the diesel. Which of course is not going to die, it is going to be priced accordingly in comparison to actually be of interest for anybody who does more than X thousands of miles per year.

All this petrol vs diesel is garbage talk.
Especially the guy with the passat estate. Good luck with paying almost twice for that car!!! I'd pay not to drive it or not have people see me in it.

Ah, I laughed a lot...

Companies are not stupid, price is the key point. Expect this engine to the mondeo, bitches, 200NM of torque is more than enough for a future mondeo that won't weigh 1,500 kgr empty!

giorikas the 56 MPG ecoboost engine will be totally clapped out when a "LIGHTWEIGHT" 91 MPG 3 pot VW Polo 1.2 Bluemotion Diesel engine has only just run in, you post is garbage (In the UK its known as rubbish).

goirikas81 you don't have a clue do you, your not American are you?

Sales Reps and folk want a reliable diesel Mondeo according to SMMT sales numbers, that will give them bomb proof Diesel reliability up and down the motorways putting 100,000's on the clock, they don't want a ticking time bomb ecoboost thats a fuel guzzler in the real world nobody wants the petrol models get real please.

I think Richie 767 that if you read my previous postings in detail, you will find I was one of the people querying the logic behind the Ecoboost and being called a "bigot" for my pains. (Incidentally my nom-de-plume is spelt "Aeolus" i.e the god of the winds; chosen for reasons best left unmentioned!)

Having seen a couple of petrol fuelled cars on fire, which is a frightening sight indeed, was an additional reason for changing to a diesel vehicle four years ago. Petrol is one of the most dangerous substances easily available and witnessing people attempting to fill their cars whilst smoking suggests a widespread ignorance of this fact.

"Sales Reps and folk want a reliable diesel Mondeo according to SMMT sales numbers, that will give them bomb proof Diesel reliability up and down the motorways putting 100,000's on the clock"

Errm no. Fleets want economical cars with low tax bands (the two being much the same thing). Whether they are petrol or diesel makes no difference. Fleet managers don't care. It's just that at the minute, the default choice is diesel, because a 2.0 or even a 1.6 petrol can't touch it. This new engine may change that.

As for reliability, nobody is in a position to question the Ecoboost, yet. Whereas modern diesels are causing havoc, having nothing like the durability of the past. Although, to be fair, the Ford / PSA diesels are probably the best ones in terms of reliability and hassle free use.

For real world fuel economy, having 170-200 Nm at 1300 rpm would suggest that the Ecoboost will actually be quite good. It'll hardly need revving at all. Don't confuse it with the Fiat Twinair screw-up. Remember, even some diesels don't produce anything like the claimed fuel economy...

The choice of a petrol or Diesel engine depends on whether you usually drive out of town at higher speeds - or mainly drive on a lot of short runs at low speeds in town.

The new generation of Diesel engines have a "Diesel Particulate Filter" that traps the carbon from the exhaust gas.

To keep the "DPF" from becoming blocked, the car needs to be driven, at regular intervals, at over 40 mph for over 20 minutes so that the filter is cleaned - or "Regenerated".

If you do not manage to Regenerate the filter in time - the engine goes into Limp mode - then the car needs to go to the Dealer's Garage for a "Forced Regeneration" - which means an expensive repair bill.

Car manufacturers now state that a Diesel is NOT ADVISABLE if you mainly use your car only for short runs at low speeds - or you live on a small island, e.g. Channel Islands, where you cannot achieve over 40 mph for the period of time required for regeneration of the filter.

People need to be aware of this before they choose to buy a new Diesel car that has a Diesel Particulate Filter.

My wife drives mainly at 40 MPG maximum and does short trips around town, it's been in the family for 15 years, l have done all the maintenance on it myself which is a doddle, changed the oil regularly every 3,000 with cheap brand oil it runs as sweet as a nut burns no oil, no blue smoke at the moment, but did get it 85,000 & 170,000 when the tappets need reshimming exhaust valves stay open a few thou. At every MOT it comes in well below half the emission limits every year. Rest of the car is falling to bits though, French electrics are total crap. Making 300,000 should not be a problem.

Would love to buy a new Ford Econetic diesel l think they brilliant, they were developed with Peugeot who make the best diesel engines in the world that are second to none, but its only the very dull tin styling of Ford cars in general that puts me right off of ever buying one. Put an Econetic diesel in a Mk1 Escort that would be awesome, l would buy two from Ford today.

Why do Ford bother with ecoboost when their buyers buy diesels?

Richie, the new 1.0 Ecoboost isn't on sale yet, and when it is, it will only be in the Focus/C-Max for a start. The 1.6 and 2.0 Ecoboost are different engines entirely and nothing to do with the discussion here...

It's great that your wife's old Pug is doing so well, those engines truly are amazing, but are you really convinced the new units are as reliable? We have one in our C4 Picasso, and as good as it is, I'm not sure it will get to 100k miles, let alone 200k without seriously expensive repairs. It's just too complex.

Richie, perhaps I did not explain clearly enough, your wife's car is 10 years old and has the OLD type of Diesel engine that does NOT have a Diesel Particulate Filter - so it is fine for driving constantly at low speed town use.
it is the NEW Diesel cars that ALL have Diesel Particular Filters - if you buy one of these for your wife to run about at low speed town use, you can expect to have expensive problems.

Everything I have ever learned about motor sport, cars and physics - power to weight ratio, says this car should be revy and deathly slow and sluggish...I hope I'm wrong

You really must Test Drive this car before making any comment. Any person with sense will understand the following FACTS and i would be surprised if people still think this Engine is Old News.

So if you drive 12000 miles per year the diesel will only save you money once you have owned it for 4.83 years!

company car drivers will pay less Income Tax driving this car

and as for performance the 1.0 125ps produces 200NM Torque and Revs at 2500 at 70mph which is lower than the 1.6 4cylinder engines it replaces.

it warms up faster to save fuel. it turns off at junctions to save fuel

it even has an ECO mode computer that tells you if you need to adapt your driving style to increase your MPG.


I wasnt I just swapped my 11reg 1.6 125ps for this car at my local dealer.

The Daihatsu Charade GTti entered production between 1987 and 1993, it was the third generation of the Daihatsu Charade, adopting the G100 chassis and only available as a 3 door hatchback. Daihatsu equipped the GTti with a 3 cylinder, 993cc, twin cam, 12 valve and turbocharged engine that produced over 99.23 BHP.

Bought a new 125 Zetec ecoboost 2 weeks back. Even thought it isn't run in yet with steady driving it is only registering 37.1mpg on the fuel computer. There is no way it will average the 57mpg claimed unless on a mototway run sticking to less than 60mph.
It may be a small turbo engine but more fuel/air is forced In the engine than a standard 1.0 non turbo car to achieve the power output of 125 Hp.
Ford's fuel economy figures are a joke as usual. 20mpg lower than claimed is a disgrace!

Certainly an emotive subject, isn't it?
As I say in other posts: I'm sticking with my Toyota Yaris petrol!
Although it would be interesting to drive one of these cars that's for sure! No doubt it will be a big seller!

Someone's post here commented on Ford not making cars here anymore. I don't suppose there is one answer but a major factor for Ford not making cars here is very poor union relations in the past.
1970's anyone? No doubt bad management as well. Cars were rubbish back then as well compared to now.

My wife's got a Fiat 500C TwinAir Dualogic. The car averages 35mpg, nowhere near the official figures. If this Ford comes anywhere near its official figures I'll be amazed, small turbo engines get very thirsty if you use the boost, and you use the boost a lot in a small engined car.
i brought a eco boost focus 125 its crap on fuel only getting 33 mpg

The main advantage of this engine is the low BIK and VED taxation. Also, diesels are noisy, and the fuel and exhaust both smell (and I have a BMW diesel, not a ropey old 80s Peugeot). As for the "it will be clapped out when the diesel is barely run in" - how many modern cars are really scrapped because of engine wear? With even basic servicing, suspension and rust problems will finish off a car well before anything oily, and it's been like that since BL stopped making engines.

I have bought this car, with this engine,(125) and can only say that It blows away all my preconceptions of the engine's capabilities. It is, an amazing piece of engineering.

i have a 1.6 ti-vct and if you know how to drive you will get better mileage than it is advertised by ford. I can get 4.8-5.4 l/100 km outside town easily, depending on road traffic, slope, and with speeds over 110 km/h from time to time. Check your tires pressure and learn how to drive a gas car. (Plenty of advices out there) If you drive at high speeds on the highway and often then you should buy a diesel. In towns, unless you do a lot of mileage, diesel is not a big expenses cut. The 1 litre from focus 3 has even a more economical gearbox than my 1.6, so I bet I could easily get the mileage they have advertised. You must drive like a pro to get good mileage from a gas engine. If you feel you drive like a noob and you are stressed about mileage then get a diesel.

i own the new focus 1.0 99bhp turbo you will be lucky to get 40mpg. on the motorway if you stick to 6omph you may get 45+ .

Anyone had problems with the windows opening automatically when the car is licked? My mother recently returned to her car in heavy rain to find all four windows open. The car was drenched. The car was definitely locked as the mirror s were turned up.its a new focus ecoboost 2013.

I own a B-MAX with the 1.0ltr ecoboost engine. While I find the performance of the engine incredible I am very disapointed with the fuel economy . Even driving at 56mph in cruise control it has never managed more than 46mpg , while normal motorway driving between 60-70mph it averages 38-40mpg .
This came as a big shock to me as i've been driving a Fiesta diesel for some years and that has always been able to better the mpg in the book .

Hertz gave me one of these for the last week on a business trip. Nice alloys and lots of electronic bits with just an EcoBoost badge on the back to denote what it was. The engine had an odd almost V8 warble and I guessed it was turbocharged quickly as I could hear the whir of the turbine and feel the boost at about 3000. Whilst a bit sluggish when slow or going up a hill a quick down change and more gas would sort that. It was actually pretty rapid even when carrying myself and three colleagues. Handling and steering was tight and overtaking or taking corners was fun dropping a gear and getting the engine into boost. It was a joy to drive, we decided it must be one of those new turbocharged 1.6.

Imagine my surprise when I got back to the rental garage when handing over the keys to the guy who checks the car over telling me it was a 1ltr, 3 cylinder turbo! Just amazing. This is the future for petrol engines!

Hi Ned,

I had this happen to me when it decided to snow overnight. It was locked, keys in a very safe un-pressable place but the windows opened and I ended up with 4 inches of snow throughout the interior.

Ford were terrible - they just didn't want to know - apparently their window mechanisms could never ever go wrong and they would stand up in court to say this.

Brilliant customer service - not.

The 1L ecoboost engine has won engine of the year twice in a row,, but more and more reports mentioned much less MPGs than given from Ford..
Maybe the gear-ratios combined with a smooth engine noise, and torque spread are fooling people to shift too late or early, or stay in the wrong gear at a certain speed for optimal fuel efficiency.. I am not sure but some have had really low MPG figures..
I do trust NA engines more.. Seem that reported MPG numbers correspond better with reality.. You do though have to work the gears more as you have much smaller torque band coming in at a higher rev number.. But I personally like that..
The 1L 74HP MPI triple engine from the VW up is a gem.. Seems to be the best small triple out there at the moment.. I know it is low on power but it feels great and responsive without the turbo kicking in at low revs...
