Until now, the focus has been on the top-spec Quadrifoglio Verde model and its 380kW, twin-turbo V6 engine, but Alfa has now revealed at least one engine for lower-spec models.
For US customers at least, all non-Quadrifoglio Verde models scheduled for release at this stage will be powered by a 2.0 litre four-cylinder turbocharged engine producing 206kW.
Power will be sent to the rear wheels in the first models to hit the US market, but Alfa says all-wheel-drive models will follow almost immediately after.
Those first models were expected to arrive in the middle of next year, but a delay of up to nine months for the Giulia and its SUV sibling means the schedule for most markets is now unclear.
The delay will give US customers time to consider the vast array of interior options, including leather and Alcantara, carbon-fibre and aluminium in five combinations.
Black, black and red, or black and Ice interior colours will be available with a choice of black, green, red or white stitching highlights.
There’s more choice on the outside, with four alloy wheel designs available including a staggered 19-inch option (8.5 inches wide at the front, 10-inch at the rear).
The list of available paint finishes includes Rosso Alfa (Red), Vesuvio Gray Metallic, Vulcano Black Metallic, Silverstone Gray Metallic, Montecarlo Blue Metallic, Trofeo White Tri-Coat and Rosso Competizione Tri-Coat (Red).
Alfa has also used the LA Auto Show to hint at pricing for the Giulia Quadrifoglio Verde in the US, saying prices will start from “around US$70,000” (AU$99,000).
