Hey i was just wondering why Ford seem to be using the Duratec now instead of the Zetec. I thought the duratec was a much crappier engine than the zetec? If you look at the figures, they pretty much speak for themselves:

SportKa 1597cc 4cyl 0-60 in 9.7 Top Speed of 108mph 94bhp
StreetKa 1597cc 4cyl 0-60 in 12.1 Top Speed of 108mph 94bhp

So considering the puma weighs even more, ill use the 1.6 as a fair comparison:

Puma 1.6: 1596cc 4cyl 0-60 in 10.4 Top Speed of 118mph 102bhp

So why oh why are they putting the duratec in the Focus ST? IS it to save cost because its a cheaper engine or something?

i much prefered the retard vs non retard thread.............

is this along the same lines ?

[Count_Dragula]

Care to explain that one? I was just doing a simple comparison apologies if it wasnt very exciting.

[eldoodarino]

all to do with

and

Duratec will replace zetec. In Ford infinite wisdom a number of engines were badged Duratec even though there were reworked Zetecs (the Focus RS springs to mind).

With regards your performance figures - they depend on lots of other factors other than the basic engine type eg engine management, weight of car, gear ratios etc.

Top speed is dependent on weight and drag as well as power. More importantly, as far as power is concerned, the engines in the SportKa and StreetKa are 8V versions, whereas the Puma 1.6 engine is 16V. Not all Duratec engines will be 8V.

the engine noise on a duratec is awful, you should hear a streetka at high revs. total disgrace for the value of the car.

Yeah this is part I cant really fathom. Why even make a 1.6 engine in a supposedly sporty car if your going to let in down with it only being 8v. Ford are just lazy i think. You can even get it in Fords 'performance blue' so they obviosuly think alot of it. Just my opinion.

It's IMPERIAL blue, not performance blue... same as the Focus RS, Racing Puma, etc

[sham]

desprate times call for desprate mesures and ford is broke.
which is a real shame they can make such good cars when
they can and want to

[Count_Dragula]

Indeed they are broke it would seem. People attack rover for keeping the same shape cars from N reg all the way to last year, yet the Ka is the same (apart from some engine minor and spec changes) now as it was on P reg. Admitadely the Ka is not Fords whole range, but my hat will go off to Rover for what they managed to get out of those cars, some of those final shape mg's were pretty nice. (To look at at least)

[BOK]

Ever heard of tightening emmissions levels, increased durability and economy (reducing revs and increasing low end torque) and the increasing weight of cars due to safety legislation

Anyway Zetec and Duratec are just brand names, they do not technically define the engine, unless a Duratec is more 'durable' and a Zetec is more, erm, 'zeetee'? Or maybe cosumers really are that taken in by the marketing bu11sh1t...?

it was ment to be too much of a squash to fit the 16v engine in the sports/streetka thats why they put a 8v in it.

i think puma build managed it tho, but it was tight
and it would hav probably cost ford more to do this, so they took the easy option.

i think the proper duratec (not the zetecs badged up as duratec) is ment to be a lighter engine.

back to the focus st engine its a volvo engine just badged up as duratec, it all get very confussing.

...and I'd be prepared to bet Pumabuild would not have to respect Legal Pedestrian Protection legislation, Frontal Crash impact or Ground clearace requirements, all of which effectively make the space in which Ford (or any other large scale automotive manufacturer) has to fit the Engine into smaller and smaller, year on year... not that I'm making excuses for them mind

[jprestidge]

The Duratec engine in the Ka is not a proper Duratec - it's an 8v version that is the only one that will fit. The Duratec in the ST150 is much more tuneable than the old Zetec, and is lighter. Caterham is using a version of this engine now, and outputs of over 270BHP have been seen.

Ford sometimed doesn't follow a very rigid naming convention - eg the turbo Zetec in the FRS was called Duratec, and the Cosworth engine in the old Bennetton was called Zetec, despite having nothing in common with the four cylinder engines in shopping trolleys, so remember to compare like with like, not 8v engines with 16v ones.

Well i guess theres not much in a name then as this post has proved. I also never realised about all the different crash stuff and how the engine affected it. Wonder what happened to that guy on here who wanted to put a 2.5v6 cougar engine in his puma.

[robcrezz]

Take no notice of fords badging. The new focus ST engine is a 2.5 5cyl 20v turbo Volvo engine.


Oh yeah, we decided that the guy who was putting the v6 in the puma was a bullpooter. he couldnt answer any questions.

[Count_Dragula]

Yeah i thought so. For all that money why not simply buy a cougar you can get one for less than a puma.

[pumarv6]

The engine in the Sport and StreetKa is badged Duratorq, not Duratech.

Which would make it a diesel

Duratec (minus the 'h') gets my vote!
