This comes less than a year after the first examples of the BMW 3 Series-rivalling executive saloon were delivered to customers.
The options, which are available as of now, include 18in five-spoke diamond-cut alloys on all trims except for the entry-level Giulia and 19ins exclusive to the hot Veloce.
In addition, twin tail-pipes (£150) are now available on the petrol Super model and the Apple CarPlay and Android Auto smartphone mirroring functions are available with all specifications for £250.
The significant price drop applied to Tecnica trim, which is available with only a 2.2-litre diesel engine, has brought P11D values down to £30,840 and £32,040 respectively for the 150hp and 180hp variants.
Tecnica is aimed at company car drivers, with standard kit including electric seats, a climate pack, privacy glass and a driver assistance pack that includes all-round parking sensors and a rear-view camera.
Alfa Romeo claims that the Tecnica now "offers the lowest whole life cost in its class, benefitting from a low P11D value, high residual values, low maintenance costs and excellent fuel efficiency".
The Giulia (not including the Quadrifoglio) has also been added to Alfa Romeo's Test Me Contribution scheme, joining the 4C, Giulietta and Mito, in which private buyers will be offered a £2000 discount if they take a test drive and place an order by 30 September.
