Hey there! I have the 1.4 16v as my own car, but I did take the 1.3JDTM out for a test drive when I was buying the car! I liked it! Smooth power delivery (which in my experience is rare for a diesel!) And I would also say powerwise that the 1.3 is veryyy close to my 16v!
As for economy etc I have no idea! lol
Hope this helps!

i drove a fiat grande punto a few months back, with what i believe is the same engine, and i was VERY VERY impressed, i had it for 2 days and done 300km in that time, it was smooth, and averaged 4litres/100km !!!!!!! thats very good...

i think they are great engines, i believe (might be wrong) that its the same engine as in the new diesel Vauxhall corsa too!!!!

 

Wow, thanks for the replies! Sounds like a sweet little engine, and although I'm not really looking at getting one any time soon (haven't even got my provisional through the post yet!), it definitely sounds like an engine to consider.

Thanks!:thumbs::thumbs:

 

you're not gonna get the economy and the power, you have to choose. either you drive economically or fast, and sometimes small engines are less economical when driven fast compared to bigger ones.

 

The diesel will still come out top for fuel consumption even if you do thrash it.

 

The Multijet 75 PS version was chosen in 2005 as the International Engine of the Year in the 1-litre to 1.4-litre category.

So the 90PS version should be only better than that
My friend has this engine in his Fiat Punto and he is very pleased with it. Consumption is around 4l/100km (~70mpg) in a Punto (old one, not Grande Punto) and it goes reasonably well for this size of car...

 

i'm really chuffed with all these comments, can't wait to get my new car now!!!

 

I've got a 1.3jtdm and had it for a week. So far I've been really impressed. Took it to Devon this weekend and was really impressed with its overtaking power etc. I'm a girl so not sure of all the technical terms. But I used to have a 1.7 diesel Merc so wasn't expecting much from a 1.3 but what a surprise. Feels no different.
On the fuel economy side, it takes about £38 to fill it up from when the fuel indicator comes on. We drove to North Devon from South Wales and drove about 20 miles each day (sorry don't have exact mileage) and I still have quarter of a tank. I didn't hold back that much either and a lot of it was driving through country lanes, so pretty impressive I think.
I'm very happy with my 1.3 Mickey the Mito. (kids thinks he looks like mickey mouse as he's alfa red)!

A few years ago I bought a brand new 1.3 16V Multijet Grande Punto with 6-speed gearbox(which was soon discontinued by Fiat for reasons that were not clear at the time). I did 20,000 miles in that car which was a joy to drive. The engine never missed a beat and it did seem to get more economical as the miles clocked up. From memory, I think the average fuel economy hovered around 46 mpg.

My only slight reservation concerned the matching of gearbox to engine: too often I would get caught in the wrong gear due to a lack of torque at 20 - 40 mph in 3rd, 4th and 5th gears. I'm sure Alfa have sorted that out in the Mito......

 

No actually it's because petrol engines use a proportion of the power they produce pumping air through the throttle. Diesel engines have no throttle so this pumping loss is eliminated.
A petrol engine actually runs more economically with your foot down (within reason), from a purely thermodynamic point of view.
Also a petrol engine must always burn a roughly stoichiometric mixture of fuel and oxygen (14:1), whereas a diesel engine can go as low as 40:1 at idle. This is why diesel engines are more efficient than petrol, and always will be.

All engines are inefficient at the edges of their performance envelope.

As for payback for diesel, it really depends on how many miles you do.

 

Wow.
Brevity is the soul of wit.

Someone should sticky this. Don't take this the wrong way, but you're my new hero Rob7909

 

Don't forget you're also in a cheaper tax bracket too than the 1.4 16v, so you'll save a few quid there too (currently £35 vs £120) so you'll save a bit of brass there alone.

Performance-wise there's really not a lot in it, especially when you'll most likely get an extra 20mpg out of the little diesel in real world driving, I've driven the 1.3 and it's rev happy, surprisingly nippy and pulls in easily over 60mpg so I doubt you'd be disappointed if you get one.

 

Plus the extra paid to buy will be reflected in the sale price when you move on.

 

REWIND!
1.3 jtdm veloce = £13,974

1.4 tb 120 bhp veloce = £13,884

so i make that about £100 differance.
not £1000

 

The 1.4TB 120 is significantly quicker than the 1.3 JTDM. I'm referring to comparable performance levels, so the 1.4 16V model is what's being used to compare against the 1.3 JTDM which does have approx. £1k difference.

 

Nice writeup too

The new Multiair engines have an idle stop-start system and a throttle-less intake so that should make the petrols a bit more efficient. Doesn't diesel also have a higher energy value per unit compared to petrol?

 

Err, I'll take that as a compliment Martini!

Loved playing about in the engines lab when I was doing my degree, working out consumption loops and stuff from first principles using an ancient dynamometer. Great fun.
