The wider Alfa Romeo Giulia compact saloon range has been revealed at Geneva.

The car, which Alfa hopes will rival the BMW 3 Series and Audi A4, was unveiled last year with a 510hp 2.9-litre V6 BiTurbo petrol engine, but now details of trim levels and other powerplants have been published.

At launch, the powertrain range comprises four new engines, adding a 200hp 2.0-litre turbo petrol; 150hp 2.2-litre turbo diesel and 180hp 2.2-litre turbo diesel. The new diesels are the first diesel units in Alfa Romeo's history made entirely of aluminium. 

Preliminary details of three trim levels - Giulia, Super and Quadrifoglio - have also been announced with final UK specifications to be confirmed at a later date.

Standard equipment on the entry-level Giulia trim level includes 16-inch alloy wheels, daytime running lights, LED rear lamp clusters, dual-zone climate control, cruise control with speed limiter, 6.5-inch Alfa Connect system and the new Alfa DNA selector.

In terms of safety features, Forward Collision Warning, Autonomous Emergency Brake with pedestrian detection, Integrated Braking System and Lane Departure Warning are all standard. 

Super adds 17-inch alloy wheels, leather and fabric seats and special interior trim. 

Pricing, full specification and emissions information will be announced closer to the car's UK launch in September.
