Unfortunately chaps, if we want the brand to survive then there are going to have to be some sacrifices.
Designing a new engine from scratch for a relatively low volume brand isn't really economic hence it will share engines from another part of the group (as it currently does...from Ferrari).
But in order to compete in the market that it does, which is not against the likes of £150k+ Ferrari's and Lamborghini's but more against top-end £80-£100k BMW's and Merc's then it needs engines more efficient and cleaner than the 16mpg, 350+ g/km Ferrari derived units they have now.
The current range of engines aren't going to be around for much longer and we'll have to just hope that they can continue to create some innovative and exciting solutions....the good news is that Fiat group are good at engines right across the whole spectrum of brands and price points from the 500 twin-air to the Alfa multi-air to the new DI engine in the 458 Italia. Even if they do base future engine's on a Chrysler unit, the new Pentastar engine is supposed to be very good and I am sure it would be adapted in a way that ensures it fits in with the brand requirements for performance and sound.
So chin up chaps....the future will be just fine.
