Ponownie pytam o konkretne dane dotyczące konstrukcji samochodu, nie zakładam że nie masz racji, tylko oprzyj się na danych a nie na ogólnikach, swoich odczuciach i niecnych intencjach dziennikarzy.
Giulietta ma inną płytę niz Bravo i to jest bezdyskusyjne.
Sztywność skretna Bravo to 10600 Nm/stopień, Giulietty 23250 Nm/stopień. Dla porównania BMW 3 F30 , która jest wieksza 29300 Nm/ stopień i jest to wartość niższa od Alfy 159 - 31000 Nm/st w tym samym segmencie.
I to tłumaczy rewelacyjne wyniki NCAP przed zmianą sposobu badania. W momencie zderzenia masz w d... piskacza systemowego, natomiast modlisz sie o wytrzymałość body.
Co nie znaczy,że jakiemus idiocie piskacz o czyms nie przypomni, ale jak pamietam, były afery rozdmuchiwane w USA, jak to ludzie wciskali pedał gazu zamiast hamulca, sam znam taki przypadek z Pl - facet pomylił pedały i trup. Na takie rzeczy żadna elektronika nie pomoże - tylko sprawna i nie na bani głowa.

Architecture
The Alfa Giulietta introduces an entirely new architecture designed to satisfy the most demanding customers in terms of road-holding, agility and safety. It ensures both exceptional dynamic performance and high comfort levels, thanks to the refined technical solutions employed for the suspension, a new-generation steering system, a light and rigid structure created from materials such as aluminium and high-strength steels and manufacturing techniques on the cutting edge.
In an age surrounded by many question marks, the Giulietta has been created as a new benchmark. A new architecture has been forged for this car.
A design that builds on Alfa Romeo’s long experience in engineering and the result is cutting edge. The entire architecture has been redesigned compared to the previous generation, using the most innovative materials: aluminium, magnesium and high-strength steels that combine very high strength and rigidity qualities with weight reduction. The lightness of this architecture translates into outstanding performance plus a significant reduction in braking.
The new floor pan is a genuine system in its own right that interacts in synergy with each individual mechanical and electronic component on the car to guarantee agility, comfort and safety

It's obvious that the priorities are lighter weight, higher rigidity and increased safety. The Compact uses a lot of aluminum in its suspension, MacPherson struts in front and a multilink arrangement in back, the main element here being a very sturdy-looking semi-trailing arm. It's notable that the inboard pivot points of the other links attach to an aluminum casting that bolts to the structure, ensuring very precise alignment. In the front of the structure, there are longitudinal aluminum lower beams that offer an additional load path in a frontal collision. It seems to work, as they had a crash-tested Giulietta on display that had been subjected to a 40-mph offset frontal impact on the driver's side, and the driver's door still opened! Also noteworthy is an extremely intricate magnesium casting that supports the dashboard, and Alfa's new twin-pinion steering system, its motor mounted directly to the steering rack.

14 kwi 2010 - max_pershin dice: Rispetto a quello della 147 più rigido del 43 per cento, con grande capacità di assorbimento in caso di urto. Giulietta torsional rigidity is 23250 nm/degree (147 5p=16250*1.43). Non prenderei questa dichiarazione alla lettera.. e comunque credo che si riferisse alla rigidezza flessionale, .
