There's a lot of unnecessary negativity surrounding Fiat/Alfa on these last few posts. As I've said before, they have not killed the MultiAir engine. It's available in 140 and 170 bhp in the MiTo (the 140 TCT has only been launched a few months ago, up from 135 bhp). They have the 170 MultiAir across the Giulietta range.
They've dropped it from the Punto range, but that's presumably because when it was available in the Punto Evo and 2012 Punto they hardly sold any. It'll be available in 140 and 170 forms in the new 500X and Jeep Renegade. It's also available in the Abarth 500.
The 500L has the T-Jet 120bhp, and no one seems to be buying them - instead opting for the 1.3 diesel (85bhp) and 1.4 16v Petrol (95bhp), so why would they go to the bother of putting a 140 and 170 bhp engine in it?
It makes sense to have a progressive range, and that's what they'll have with:
500 & 500c (1.2 8v 69bhp, TwinAir 85 & 105bhp, 1.3 95 diesel),
500L (1.4 16v 95, TwinAir 105 & 1.4 T-Jet 120, 1.3 85 diesel, 1.6 105 diesel & 1.6 120 diesel)
500X (1.6 petrol, 1.4 MultiAir 140 & 170, and 1.3 95 diesel, 1.6 120 diesel and 2.0 140 diesel)
A few weird choices like putting the 95bhp diesel in the 500 and 500X but only an 85bhp in the 500L. Also not sure why they've used the 1.6 in the 500X and not the T-Jet. Perhaps to keep entry model costs down. But overall, it's a good range. Then there's the Panda models and will be Bravo replacements next year by the look of it.
The Fiat range might look a bit weird at the moment (I agree it's all tiny cars and MPVs) but they've kinda had their work cut out with Jeep/Chrysler and are probably trying to get new models to all the brands, not just one - hence Maserati Ghibli, Fiat 500L and soon 500X, Alfa 4C, Jeep Cherokee & Renegade. There's all the realignment of factories and platforms so that they work across brands too.
There's no point having all the brands covering all the different markets. It makes sense that Fiat sell small cars/MPVs/SUVs, Alfa does the more traditional and sporty range, Jeep the 4x4's and Chrysler, urm, well, yeah, God knows - I don't really see the point in Chrysler outside of the USA. So it might be that a model you used to buy from Fiat is now under the Alfa umbrella - it's all the same company, just a different badge.
