General 1.3 diesel my arse
Not to worry. Did a quick google. Don't think the inline 2 engine will be a parallel twin. Sharing the same crank pin as a parallel twin does and having the cylinders firing at the same time would cause lots of vibration. I reckon it'll be the same as a normal inline engine.
Fiat is going to use the 450cc cylinders in a modular manner to make all sorts of engines so I don't see them making it a parallel twin and then doing it differently for all the other engines.

but are they going to sound like those old fiats 126? that had a twin cyl engine plus are we looking bus type performance
two cylinder turbo you're look at 100-ish bhp. For the NA one it'll be about 60 bhp so not too shabby. Remember they'll also be very light lumps too

Don't forget though that bands are used for various taxation and company car charging rules. For instance a company car policy may have a private mileage charge based on CC which will be banded. A 1248 cc car listed as a 1.2 would confuse, so anything over 1.2 gets listed as a 1.3 to ensure it is in the correct band (most people don't know the exact cc of their car, just if it a 1.4, 1.6, 2 litre etc.). Just a thought...

well why would they be firing together
they will both be on the same crank and they will both visit the top of the stroke together but one on exhaust and one firing
So the crank must be heavily counter balanced then if both pistons travel in unison? or surely the momentum of mass would cause big problems?
no that's how old fiat 2 cylinders are if you had the cylinders working against each other it would be much much worse for an example of what would happen stand a bicycle up and spin the cranks round buy hand with the chain off and you'll see why it's not done that way
anyway i always thought the 126 and old 500 were wonderfully smove and had a very cute note

True. But as I said there'll be lots of vibration for the reasons the beast stated.
yes there will be more vibration than a conventional 4 cylinder i would expect but much much less than an in-line 2 with pistons opposed to each other
you really need to go see a classic 500 there really isn't much vibration at all from them and that is now 50 year old technology
so with today's technology i'm sure fiat will produce a perfectly acceptable smooth engine

Oh I don't doubt Fiat will make a great engine. If there's one thing Fiat have never struggled with it's been engines.

No, not even close.
Lets do the calculation. 43,000 psi!
Not the compression.
The injector pressure.
Enough to sever your hand off your arm, if you happened to put it in the wrong place!
The cost of materials for block or heads or whatever, not a factor.
The cost of injectors that have an internal pump that can produce that sort of pressure and live in the environment of a high compression engine, is not inconsiderable.

I guess they need good head gaskets then
