Isn't the Ypsilon based on the punto already, so there seems little space for another model there.
Lancia should be basing their model range on the lower end Mercs plus Ypsilon
So,
Ypsilon 5 door hatch (Grande Punto base)
Delta 5 door hatch (bravo base) A-class
New 'Lybra' 4 door saloon + est (Bravo Plus base) C-Class
Thesis saloon + estate (New 169 base) E-class
Fulvia 2 door 2 seat coupe (Grande Punto Base) new SLA
Flamina 2 door 2 seat roadster coupe SLK (Bravo plus base)
New 4 seat copue/conv. (thesis base) CLK
SUV (bravo base same as 149 SUV) New GLB
SUV (based on LR Freelander) GLK
This model range would allow Alfa to move further into the sports GT end and create a 'Ferrari for the masses'
Their model range would be
Mito 3 dr hatch A1
149 5dr hatch plus coupe version A3
159 4dr saloon, 2 dr coupe, 5 dr est. A4
169 4dr saloon, 5 dr est, 2 dr coupe A6
Spider (Based on Bravo base) competitor TT
6C Audi R4 (Mid-engined on Lotus elise similar to Arbarth coupe)
8C Audi R8
Maserati could compete with top end GT
Quattroporte 4 dr saloon A8
Coupe 2 dr coupe/spider
