Next-generation Ford Fiesta ST likely to get EcoBoost 3cyl turbo
AutoExpress.co.UK

Sean Carson - 28 Sep, 2016


Ford has dropped more hints of what’s in store for its next Fiesta ST hot hatch – revealed in our exclusive main image – and it’s likely that the all-new performance supermini will use a tuned version of the firm’s 1.0-litre three-cylinder EcoBoost engine in place of the current car’s 1.6 turbo.

Ford’s head of small cars in Europe, Darren Palmer, told Auto Express: “We’re seeing more and more of what we can do with the 1.0-litre engine in development and the signs are promising. It’s a great engine – it sounds brilliant and there’s loads of torque when the turbo comes on boost, so we’re looking into things for the next ST.”

Currently, the highest output from the three-cylinder turbo in production form is 138bhp, but back in 2012 Ford specially tuned the EcoBoost unit to 202bhp in a one-off version of its Formula Ford racer.

If this power level could be achieved reliably in the forthcoming ST, it would give a 12 per cent increase over the current hottest Fiesta. Palmer told us: “There’s still a huge demand for the ST – we’ve seen that with the current ST200. But we want to offer more, so expect more performance and efficiency.”

The logical way to achieve this would be to use the 1.0 EcoBoost motor, and with Ford announcing it will halve production at its engine plant in Bridgend, south Wales, which makes four-cylinder engines exclusively, the manufacturer is set to increase the use of its three-cylinder unit in future models. The Fiesta ST is likely to be one of these....

I'm wondering when we will see an all new Ecoboost 4cyl. The current ones still share a lot with the Mazda MZR that debuted in 2001 don't they?

Wasn't the latest 2.0 different than the old one and all new?

I'm wondering (practically willing to bet) that/if there'll be a companion, smaller v8 (near 4.0) out of this program...
...would think a shorter stroke & Turboing
Maybe a version of this new 4.8L will make it into the New Navigator and Expedition.

What if the 4.8 is an all new engine specifically for Ford and they build a larger version like maybe a 5.0 exclusively for Lincoln? Or a smaller version with turbo?

You are correct, the current 2.0L and 2.3L utilize the co-developed (Mazda/Ford) powertrain. Same bore, stroke, bore spacing, valve train architecture, etc. Updated castings, especially cylinder head with IEM is the major differences. The biggest cost to updating to all new designs, usually is the bore spacing that relates directly to factory assembly line and re-tooling, crates, machining re-tooling, etc. But yes, all new replacements have been in the works for some time now. Remember, all new = 4-5 years development.
Wings, thanks for information and staying on topic. Maybe (wild) speculation about new V8s can be on a different thread.:)

A 4.7 liter (289cu in) EcoBoost V8 for Ford and 4.8 liter (292cu in) EcoBoost V8 for Lincoln would be interesting. :D

Another interesting issue may arise as well. Sorry for political stuff, but Trump has stated that he would consider tearing apart the fuel economy standards imposed by the Obama administration as well as possibly disbanded the EPA. What sort of effect would this have on the automotive landscape?

A swift reversal of White House policies would not be unusual. President Barack Obama made similar moves in the early days of his administration after succeeding George W. Bush. Those moves included some of the environmental policies and regulations, who many believe are excessive, that can soon be reviewed by Trump. I am all for this. Regulations have gotten out of hand, clearly, constantly adding new ones. Don't buy into the alarmist media BS that was pushed to keep their candidate's momentum.

new v8 ... so SOON?

Sources Say: F-150’s 4.8L V8 To Feature Dual Injection, Replace 5.0L Coyote
FordAuthority

by Aaron Birch — Dec 19, 2016


Should the refreshed, 2018 Ford F-150 and 2018 Ford Mustang bow at next month’s Detroit North American International Auto Show as we’re expecting, both cars might have the same new, normally-aspirated 4.8-liter V8 wedged under their hoods.

The engine, which was alluded to during discussions of the new labor contract between Unifor and Ford Canada, will outright replace the 5.0-liter “Coyote” V8 currently found in both the Ford F-150 and Mustang GT, according to an unnamed source. The same source tells us that this new engine will feature dual injection – that is, both direct and port fuel injection – to achieve greater efficiency than the outgoing 5.0L...

...The combination of both dual injection, and variable valve timing like that found on the Coyote, should permit a higher compression ratio than the Coyote’s respectable 11.0:1. With higher compression generally comes more power, meaning that the new 4.8L could well outperform the 5.0, despite its slightly smaller displacement...

Re: new v8 ... so SOON?

Does higher compression favor horsepower or torque more?
I am guessing this will have better performance, and slightly better MPG than the Coyote with the 10-speed.

Re: new v8 ... so SOON?

It does seem odd to me that they would be coming out with a completely different motor already rather than applying the updates to the Coyote. Wonder if it will maintain the current flathead style firing order or go back to the modular V8 firing order.

Maybe they still will do updates for the 5.0 but only for something like the Super Duty? Wonder if anything will be shared at all with the 4.8 but from the sounds of the article it might be all new.

For what it's worth, Coyote upgrade includes slightly bigger displacement.
So are you saying the Coyote is being upgraded in conjunction with this new 4.8 V8? Are we talking like a 5.2?
