longsh07 Posted September 28, 2016 Share Posted September 28, 2016 Hi all, First off let me apologise if this kind of 'Which one should I buy?' thread is common around here. I have used the search as well as done a bunch of research elsewhere but I felt it best to ask the question direct in the end. Me and the missus have just bought our first house and we'll be moving in in a few months time (it's a new build). For me that means a longer commute of 17.5 miles each way vs the 6.5 miles each way I currently have. Given that and the fact we're going to have to start paying bills like real adults I'm looking to change up one of my cars for something a little more economical without sacrificing good handling. I currently own a Nissan 350Z GT4 as well as an FN2 Honda Civic Type R. The Type R is the one I'll be replacing so I'll still have the 350Z as a weekend toy. Given the research I've done I'm pretty much set on a Mk7 Fiesta, and I've narrowed that down further to either a 1.0 Ecoboost 100 or 125bhp depending on availability or the 1.6 TDCI. Can anyone help me pick between these? Having never owned a diesel I've no idea what is considered a short journey to avoid clogging up the DPF or if claimed MPG figures are actually realistic. In terms of torque difference I'm familiar with how they differ and what that means in terms of driving style. I also have no idea if diesel of petrol would be better given the roads I'll be using. Can anyone shed any light on which one I should pick? To give a bit more info: I'll be doing roughly 10000 miles a year, with a 35 mile commute 5 days a week on mostly 50-70mph roads (single and dual carriageway). Also I know I'll end up having to scratch the modifying itch, (I've already looked at rear drum to disc conversions from PumaSpeed), so which one would be better for tuning? If I can gain a handful of horses and better braking/handling I'll be happy, nothing crazy. ST models are out of the question. Part of my requirements for the Civics replacement is it must be 5 door, cheap to run, cheap to insure, and cheap (£0) to tax. Appreciate any input you can give!

alexp999 Posted September 28, 2016 Share Posted September 28, 2016 I'd definitely go 1.0 for that mileage. My dad is doing about 12k per year on similar roads and gets over 50mpg from his 140PS 1.0 Fiesta. 1 Quote Link to comment Share on other sites More sharing options...
dfriel2 Posted September 28, 2016 Share Posted September 28, 2016 If you were doing double that mileage, I still wouldn't consider the diesel over the 1.0 ecoboost.. 1 Quote Link to comment Share on other sites More sharing options...
James Posted September 28, 2016 Share Posted September 28, 2016 Definitely go for the 1l ecoboost 123bhp. I plan to change my diesel car for a Focus 1l ecoboost 123 bhp in January. They are seriously good engines. The 1.6tdci is an old engine at this stage. 1 Quote Link to comment Share on other sites More sharing options...
longsh07 Posted September 28, 2016 Author Share Posted September 28, 2016 Thank you for the input all. I saw in another thread on here that the 100bhp is identical to the 125bhp mechanically and can be remapped to gain those extra ponies. Is that true? If so I'd happily get a 100 if that's all that's available when I'm looking then give it a remap when I feel the urge for a bit more grunt.

JustKarlos Posted September 28, 2016 Share Posted September 28, 2016 I'd personally recommend the TDCI. Although the TDCI is now practically an outdated engine as apposed to the ecoBoost it still does well on mileage. I'm currently commuting 28 miles a day 5/6 days a week and hitting 48mpg which realistically isn't too bad considering the country roads I am on. The torque is nice too. I'd suggest taking them both for a test drive and see what you prefer. 1 Quote Link to comment Share on other sites More sharing options...
longsh07 Posted September 28, 2016 Author Share Posted September 28, 2016 Cheers @JustKarlos, trying to line up a couple to see over the weekend. If I can find somewhere with one of each that would be ideal. 1 Quote Link to comment Share on other sites More sharing options...

ceeveepee Posted September 28, 2016 Share Posted September 28, 2016 I have a mark 7.5 1.6 TDCI. My commute is about 7-10 miles each way in town traffic plus shorter trips to shops etc with longer motorway trips every few weeks. I'm averaging around 56 mpg (according to in car calculation) so really can't complain at that. I find it very nippy as well, but that's coming from a 1.25 petrol mark 6 (which only gave me around 36mpg for the same commute I have heard great things about the ecoboost engines though.

longsh07 Posted September 28, 2016 Author Share Posted September 28, 2016 @ceeveepee Good to know about the TDCi MPG, thank you. Yeah the Ecoboost always seems to be the recommended one by the big review websites. Quote Link to comment Share on other sites More sharing options...
Guest Posted September 29, 2016 Share Posted September 29, 2016 Get yourself a red edition mate. 1L but still packs a punch with the 140bhp. Realistically though, the 1L aren't really as economical as they make out, i get between 34-38mpg around town in mine. Quote Link to comment Share on other sites More sharing options...

My dad's getting over 50 MPG from his 140. You don't have to have it as a red/black edition anymore either. Quote Link to comment Share on other sites More sharing options...
dave_k Posted September 29, 2016 Share Posted September 29, 2016 I've got the 1.6tdci and travel on mostly A roads and get around 58-60mpg driving conservatively with just myself in the car 95% of the time. Free road tax too. Got to keep them well serviced though (which may offset running costs v the 1.0 ecoboost) as its the dv6 engine, but otherwise very happy with it, economical and plenty torque when you need it.

TomsFocus Posted September 29, 2016 Share Posted September 29, 2016 I don't know how the 1.0 Mk7 can be so uneconomical round town for most people? My 2.0 ST150 does 30+mpg round town...with half as much engine and a much more modern and accurate fuel delivery I'd expect a lot more mpg! Personally I wouldn't go for another 1.6TDCi in any car, it's not as economical as I'd hoped, and the servicing and replacement parts have wiped out the savings from the cheaper tax.

Was expecting better from mine. Currently in the mid-30s with my 123. Aiming for 280 miles to a tank. All town driving. Lots of start stop stuff. On the motorway I was getting 50 ish mpg.

longsh07 Posted September 29, 2016 Author Share Posted September 29, 2016 @fraserrg @alexp999 From what I've seen the only 140's are 3 door expect for the ST-Line Nav model. I can't see any of those available at the moment near me and I expect they will be out of my price range. Is there a significant mechanic difference other than power output between the two or is it another case of remapping a 100 will 'unlock' the same power as the 140?

longsh07 Posted September 29, 2016 Author Share Posted September 29, 2016 @dave_k Good to know. I'm fairly handy with a spanner so I could do basic maintenance on either mode if I need to save a few quid. Again though, having only worked on petrol's in the past I'd probably need to familiarise myself with a diesel engine a bit more. At the end of the day they are the same car so will be 90% identical with the only real variation being the engine plus intake/exhaust tracts. Either way a car is a car is a car, I could figure it out @TomsFocus As I said above, I can work a spanner but if the parts are more expensive generally or it requires specialist work then I can see the potential extra 10mpg saving going out the window pretty quick. @GaryPL I've seen a lot of that. Most of my journey will be single/dual carriageway A roads to/from work with only a couple of short 30/40 stretches. If you were getting 50+ on the motor way I think getting around that on A roads is a reasonable assumption. Really appreciate the input you've all given me. Still slightly leaning toward the 100/125 Ecoboost at the moment. If anyone has any or can point me towards any good info regarding the actual mechanical differences between the 100/125/140 (if any) that would be a big help Edit: Am I right in thinking there is something stamped on the turbo to identify which output it is?

alexp999 Posted September 29, 2016 Share Posted September 29, 2016 140 and 125 are mechanically different. Not sure about 100 and 125, think it depends on when it was built. You can get 140 5drs new, but if you are looking second hand and want 5drs, 125 will be highest output you can get. Quote Link to comment Share on other sites More sharing options...
longsh07 Posted September 29, 2016 Author Share Posted September 29, 2016 @alexp999 New is out of my price range. Ideally I want to do a straight swap but realistically I'm limited to whatever I can get for the FN2 Type R + about £1000. Private I think I could get about £7k for the Type R given age/mileage/condition but I can't be bothered to worry about selling it along with all the house stuff going on so I'm willing to take a hit and accept part ex. value for it. Total budget then is somewhere between £6-7K. Just came across this piston heads thread with some useful info in it. http://www.pistonheads.com/gassing/topic.asp?h=0&f=23&t=1522657&i=0 One of the posters said he found that the 100's turbo was made from a slightly different metal which melts at a lower temperature vs the 125 which can take higher temps. This isn't a big deal really though as simply swapping out the turbo from a 125 or even 140 would improve the performance and reduce the risk damage if a remap was performed.

alexp999 Posted September 29, 2016 Share Posted September 29, 2016 At some point Ford started fitting the same turbo to both 100 and 125, I just don't know when it was. Quote Link to comment Share on other sites More sharing options...

longsh07 Posted September 29, 2016 Author Share Posted September 29, 2016 @alexp999 A wild stab in the dark would assume when they face lifted the car. Something to keep an eye out for though certainly! Quote Link to comment Share on other sites More sharing options...
alexp999 Posted September 29, 2016 Share Posted September 29, 2016 1.0 ecoboost has only been available since the facelift. It has changed since then. The 140 has an uprated head gasket and different gearbox/diff ratio. Quote Link to comment Share on other sites More sharing options...
