1.4 - Fiesta TDCI - another change - pork_pie
Hello
I have had my pre reg 61 plate Ford Fiesta Titanium 1.4 TDCI for 3 months (3500miles) and the economy is fine despite the label saying 68.9mpg (107g/km). I am very happy with it and my driving style means that 70ps is more than enough for me! I notice many people on here have cars with this unit and say its underpowered and thirsty lol

I notice in some literature that there is a latest version that is rated at 104g/km which equates to 70.6mpg - not a huge leap and still falls short of the magic tax exempt point.

Cars advertised with such amazing claimed fuel economy do not deliver at all eg the latest 1.6 TDCI econetic that offers 86 mpg and the Kia Rio certinaly does not return 88 either.

I was wondering what improvements does the latest 1.4 version have over mine not that I’m bothered the latest version is going to be replaced again later this year when the revamped version comes up.

I doubt very much it will have stop start and brake regeneration otherwise the claimed figures would be much bigger. I get between 57-61mpg and the engine has yet to be run in.

And it says nothing about the 1.4. Just everything about the 1.6 econetic. Next

Neither of these technologies achieve huge real world results-although judicious use will realise some benefit. Unfortunately, the NEDC is basically a random number generator and results should be treated with caution. I'd be happy with 60mpg; best bet is to avoid advertorials-they're written with advertisers in mind and are designed to tempt you into the latest model.

Most of the latest whizz bang technology on diesels was standard fare on truck engines 20 or 30 years ago so don't feel you're missing out on a step change in efficiency. Fuel economy figures are like GCSE results-they go up every year-but education improves much more slowly!

If you're happy with the Fiesta 1.4 TDCi then stick with it. The mpg you are getting is not bad but is around the quoted urban figure (58.9 mpg) and should be better on a run, it's typically average for a 3.5k miles engine for mixed driving. These engines need around 12k+ miles to achieve their best mpg.

Having said that I find that a Fiesta 1.6 TDCi Econetic offers a more comfortable ride thanks to it's thinner and higher profile tyres, the engine is fine and nicer than the 1.4 TDCi. However, in general the Fiesta diesels could do with more noise insulation fitted between the engine bay and the cockpit. The potential 78.5 mpg (combined) (95g/km of CO2) can be easily exceeded on a long run for a car with 12k+ miles on the clock, so much depends on how the car is driven, road conditions, weather conditions, fuel etc.

The latest Fiesta 1.6 TDCi Econetic offers better fuel economy 85.6 mpg (combined) (87g/km of CO2) and is well worth considering if you're interested in a new car.

I would not change my car just for a 2mpg improvment- the cost to change for a brand new one would be about £4k-5k depending on level of discount which is a bit crazy.

Changing it was not on the menu anyway.

The trim i have is Titanium and the latest econetic in this form is nearly 17k which is an awful lot of money even for 86 mpg which I doubt it would touch even when run in. It is also a lot of money for a small car but I am sure after a few years, big discounts will be had. Also I hear the 1.6 diesel has a problems with its turbos failing due to lubrication issues.

The weight of the car also affects the co2 output. The engine may be no different, they may have simply found a few kgs to lose.
