Emozionante e bellissima. Bravi.

La CLA 45 AMG ha un discreto successo negli Stati Uniti, e Giulia 4 cilindri e' più leggera di una CLA 45 AMG.

Che non lo facciano a caso credo sia ovvio! Un L4 costa meno di un V6 biturbo!!!

Avranno sicuramente valutato che il gioco vale la candela, e che se dovesse invece rilevarsi un flop (intendo la motorizzazione, non l'auto) di V6, (ITALIANI ), pronti ne hanno già più d'uno.

Ad ogni modo caro Taurus, la C-Klasse su quella fascia di potenza utilizza un V6 biturbo, leggasi C450 amg! A meno che gli obiettivi di Giulia non siano cambiati...

gonfia, tanto e le ruote da 19 sembrano piccole

Curiosità... La Quadrifoglio US Spec da cosa differisce dalla EMEA Spec?

I see that you are avoiding to answer to my questions and statements. I don't know if it's about you technical ignorance or ignorance because of English language. If latter is truth than I ask someone to translate my post.

You can't compare CLA to Giulia. One is based on hot hatch and has transverse engine where they can't put V6 while other is in segment above and is RWD.

Negli ultimi anni molti offrono motori 4 cilindri da oltre 300cv negli USA, come la Mustang 2.3 Ecoboost 310hp(315cv) oppure la Mercedes CLA 45 AMG 2.0 375hp(381cv) che ha un discreto successo commerciale negli Stati Uniti

But Mustang has much less power than Mercedes and has 0.3 liters more capacity. Actually that 2.3 liter Mustang has slightly less HP/liter than 2.0 Giulia with 280 HP.

If you look at premium D-segment than all of them offer 3.0 liter V6 or I6 engine for more than 300 HP. Only exception is Volvo for S60 where they offer 305 HP (same engine exists as 320 HP for even bigger car) but with supercharger for low revs.

Now I will compare power and torque curve of 2.0 Volvo Twincharger, 2.0 Mercedes with single twin-scroll turbo and 3.0 Maserati with bi-turbo.

As you can see Mercedes engine is not even close at low rpm to Volvo not to mention Maserati. At 1500 rpm Volvo has 75 HP with 350 Nm, Mercedes has 55 HP with 250 NM while Maserati has 90 or 95 HP with almost 450 Nm.

For marque like Alfa that power and torque curve at low rpm like in CLA45 is not acceptable. But as I show it's possible to achieve decent power and torque at low rpm from 2.0 engine but not with single turbocharger. Thus I believe that 2.0 with 350 HP for Giulia will use electric or mechanical supercharger for low rpm.

Ah, per chi criticava l'assenza dei LED come anabbaglianti:

All-new Alfa Romeo-specific turbocharged four-cylinder engine and available all-wheel drive

Also arriving next summer, an all-new 2.0-liter direct-injection all-aluminum turbo engine, designed specifically for Alfa Romeo, will deliver a class-leading 276 horsepower and world-class levels of performance, efficiency and refinement on other Giulia models. This innovative engine will also feature a MultiAir2 system that simultaneously controls both intake valve opening and closing events to more effectively manage combustion quality. This electro-hydraulic fully variable-valve lift technology ensures the appropriate and effective compression ratio, plus efficient internal exhaust-gas recirculation (EGR) for improved fuel economy.

All-wheel drive will also join the four-cylinder turbocharged Alfa Romeo Giulia lineup in 2016, providing maximum traction on any road surface.

Qui davvero hanno messo il meglio del meglio: ID, MA in aspirazione, turbo, alluminio... Volendo 4x4...

corretto informazione

Quindi MA anche sullo scarico, su una cilindrata più grossa e turbo, dovrebbe rendere molto meglio (in proporzione) del 1.4 o del 2.4 Tigershark?

Qui davvero hanno messo il meglio del meglio: ID, MA in aspirazione e scarico (quindi EGR interno al cilindro), turbo, alluminio... Volendo 4x4...

No, MA just on intake valves. AFAIK that's enough for EGR with MA.

Forza Giulia!
