Is this any good? My sister is considering a Focus with a 1.0 (125) engine and around 60k miles. Like me, she thinks 1.0 is a bit small and that's a fair mileage for a tiny engine, but I understand it's a pretty good motor. Is it reliable? Is the 100hp version any good?

Thx

Nylon coolant pipes, overheating and head gasket issues were common with the early engines, worth checking to make sure these have been sorted.

They didn't call it the Ecobang for nothing smile

I have driven a few later hire cars with this engine and it is very impressive for a 1 litre 3 cylinder engine. Very smooth and quiet unless you rev it really hard then it gets a bit harsh, and quite torquey. It pulls well for a small engine and doesn't feel like 3 cylinders.

I didn't find them that economical though.

All of these things. We run one as a courtesy car and it's thirsty as hell on the motorway. Our Ecobang Fiesta is amazing on fuel, doesn't matter how it's driven a tank lasts forever

So, subject to the known issues, the 1.0 is good in a Fiesta and not good in a Focus?

Can't comment on the Focus, but on the Fiesta it's only the early models that suffered with the coolant pipe. The later ones have the modified pipe and they are absolutely fine and give no issues. The early models can take the modified pipe, it's a straight swap, takes about 20 mins to do and the pipe is about £40 off Ebay.

The missus has had a 1.0 125 Titanium X from new which is 5.5 years old now and hasn't had a single issue. Ford's claimed mpg figures are typically a crock of shlt though. It does low 40s locally and bang on 50 mpg with CC set at 70mph on the M62 between Bradford and Rochdale when I was using it to go to work last winter which had plenty of days of strong headwinds and standing water to plough through.

Don't be put off by the engine size. The turbo does an excellent job of shifting it along when required. It'll just about do 130 on the flat hehe .

ETA: Unless you specifically need the bigger space of the Focus (estate?) then why not go for the Fiesta? There's acres of the room in the front of them and even with my long legs, the seat needs to be a good way forward in order for me to reach the pedals which allows ample legroom for an adult behind. Fiesta's aren't the small cars that they used to be back in the 80s and 90s. The only big difference between the Focus hatchback and Fiesta is the boot space.

No idea. It's not me, it's my sister, but I'll pass on the comments, thanks. smile

Nope, just that our Focus is thirsty as hell and our Fiesta is very economical

We ve got the Ecoboost 140bhp in our Fiesta, and i quite like it and its good on fuel, i do a 70 mile round trip and i normally see anything from from 55 to 60 mpg.

Admittedly im not pulling any trees up and its normally at 60mph.

100bhp would seem a little underpowered in the Focus to me though.

I thought the coolant hose issue was only on certain years, ours is a 16 plate.

Had the 1l (140ps) ecoboost in my last focus. Cracking engine and never felt slow in a biggish car

Obviously nowhere near the ford claimed figures. Used to get an average around 35-40mpg.

It went in for a service and we had a fiesta with the same engine for a few days, that was superb to drive

Thanks all, it looks like the suggestion of a Fiesta may have been a good one.

I've had at least a dozen versions of this engine in both Fiesta and Focus.

In the Fiesta, 100ps is more than adequate and makes the car lively and fun with around 45-50 mpg in my experience.

In the Focus I've had 100ps and 125ps and the 125 is by far and away the better option. Although the numbers (0-60, max speed etc) look very similar, on the road the 100 feels under-powered and lacks throttle response, struggling on hills and when carrying 4/5 up. Just bimbling about it feels fine but there was nothing left in reserve and I found myself pushing it hard to make any sort of progress. It was also no better than the 125 on fuel, probably because I was pushing it harder.

The 125 is a brilliant option in the Focus and is smooth and refined with good punch when you need it from the turbo, without having to work the engine hard. I averaged 44-47mpg in mine with over 50mpg on a longer run.

The 100 has a 5-speed gearbox (both Fiesta and Focus) while the 125 gets a 6-speed which combined with the extra power, makes the 125 so much nicer to drive.

Just to clarify the above post, both the Fiesta 100 and 125 are 5 speed boxes. But they are high geared and no problem sitting at 90 on the motorway if you wish, without the engine screaming.

One extra thing I'd add about our Fiesta 125 is that the turbo lag is horrific There's a full 2 seconds of nothing between gear changes when you're booting it. Feels weird when coming from my Focus ST which has no such turbo lag issue.

Yes, I stand corrected.

Latest Fiesta now has 6-speed on the EcoBoost engines.

Not sure how yor sister stands on insurance but I tried both variants of the 1.0, back in 2015, then the ST.

After the ST, there was no way I was ever going to buy a 1.0 and it did 38-40mpg all day.
