To start, i hated the golden logotype as well.
Chevrolet in Brazil always followed the Opel / Vauxhall style, including designing cars to be sold also by them ( Meriva, Astra Sedan, ... ). They always mixed the opel logo with the chevrolet logo in a discrete way. Just take a look:
I don't understand why they are using the golden logo. They started doing it on
the Omega (Actually a re-badged Holden Commodore).
Anyway, about the engines, remember that those are for the normal, family versions. There will probably be a SS version with a Turbo or a V6 engine.
The design is more similar to the actual Opel / Vauxhall Astra than the new Opel / Vauxhall Vectra. Why i'm saying this? Brazilian GM said it's using the Opel / Vauxhall Astra platform, and the sides and front bumpers are almost identical.
Anyway, just because the car is a Chevrolet it does not mean it will be sold in USA. Chevrolet is in Brazil for a longtime (actually since 1925), and most of the cars are designed here or are the european cars
Brazilian Chevrolet Line-up
- Chevrolet Celta - Smaller, different styling and more dreary version of the Corsa
- Chevrolet Corsa / Corsa Sedan - Almost exactly as the European Corsa, but with a different front
- Chevrolet Montana - UTE designed in Brazil
- Chevrolet Meriva - Same as the european (designed here)
- Chevrolet Astra / Astra Sedan- It's the old european generation with some differences in the front and back
* The Chevrolet Astra Sedan SS *
- Chevrolet Zafira - It's the old european generation
- Chevrolet Omega - Re-badged Holden Commodore
- Chevrolet S-10 / Blazer - Both designed in Brazil
Hope that clears all doubts.
