Isn't it only the 2.2 that's got a GM block though
If only! -But unfortunately all have GM blocks including the V6...
The block is still an important part of an engines design - think of it like building a house when somebody else has already put the walls up - there are only so many options you could achieve regarding the layout. So while I'm sure you would produce something good and acceptable, it will probably not be ideal. Alfa (and Fiat) have been renowned for the Aluminium casting abilities so why stop!
I wouldn't normally keep on about this, but to me what they have done is sacrilegious - taking probably the best V6 engine ever produced and axing it for something that was part GM!!!
No more will get the thrill of opening the bonnet of a V6 Alfa and seeing that incredible piece of engineering, the wail of it at full tilt....
Lets not forget Alfa have been responsible for building some of the greatest engines of all time: The original Alfa twin cam (complete with timing chain) was first produced in the 1950s and carried on until the mid nineties and was a bench mark for twin cam engines. Including a twin spark version back in the 60s as well as the late 80s Twin sparks, the flat four as used in the Alfasud was another marvel of engineering (have a look at a Subaru flat 4 - something very familiar about it) and then there's the V6...
I'm not knocking the Brera I think its a good car, but is it as good as it could have been?
But to get one point straight these engines have not been superseded by something better, they been superseded by something cheaper and I for one feel cheated!
Anyway this is just my view and I'm sorry if that has offended anyone.
Great article in Auto Italia this month about the Alfa Twin Cam!
