Glad you're loving it! Alfas are definitely more than the sum of their spec sheets. Yet spec per £ is quite high to start with on an Alfa.
Well allegedly the new aluminium block, slightly revised head version of the 1750Tbi which is being developed for the Alfa 4C will have 230 bhp for starters (I suspect that's not just on overboost, as we already have 230bhp on overboost from the 1750Tbi in the Guilietta Cloverleaf).
They are also claiming there will be a 300bhp version of the 1750Tbi in the 4C. I suspect this would require a twin turbo? Can't see how else they can get so many horsies out of 1750ccs.
I have to say, if they are going down the twin turbo route then I am hanging on for that version - I don't like the idea of the peak torque on the current 1750Tbi being at 1500 revs - it's too low. Twin turbo will make it the perfect engine - other than exhaust note, but you can't have everything. Maybe I'll have to keep my 2.2 for auditory thrills
Now it's hard to say that these engines would definitely make it into the Giulia, but surely it would be financially bonkers not to amortise development costs across more than one model? Then again, the engine itself is already developed, they are only developing a new alu block and some revised gubbins.
If the revised aluminium single turbo 1750 does make it to the Guilia, it may be that the twin turbo/300bhp version does not, depending on whether Fiat group want to chuck the Chrysler-developed Pentastar V6 into it. That would be in the 300-350 bhp region but much heavier, so you would be unlikely to find both the Pentastar and the twin turbo 1750Tbi available in one model.
Then again maybe the 300 bhp version of the 4C is just BS. We live in hope.
