The 3 sedan, known previously as the GQ3 and QC3, was revealed in December and its Geneva unveiling will mark the new car's first European appearance.
Joining the sedan will be the 3 Estate and the 3 Cross Hybrid, representing regular and high-riding wagonised versions of the four-door 3.
In sedan form, the 3 measures 4615mm long and 1839mm wide, making it a little less than 100mm longer than the Focus sedan.
The carmaker promises a spacious interior and a strong set of features and trim options, including an eight-inch touchscreen display.
The 3 is yet to undergo Euro NCAP crash safety testing, although Qoros says development of the new sedan focused on achieving a top rating.
While the 3 Estate will utilise the same 93kW/155Nm naturally-aspirated and 116kW/210Nm turbocharged 1.6 litre engines found in the sedan, the Cross Hybrid features a petrol-electric hybrid setup.
Driving the Cross Hybrid is a 1.2 litre turbocharged petrol engine mated to a pair of electric motors: a drive motor mounted over the rear axle, and another operating as a generator.
Power and driving range details for the Hybrid have not been revealed, although Qoros says owners will have access to three driving modes: petrol front-wheel-drive, electric rear-wheel-drive, and petrol-electric all-wheel-drive.
Watch for more details to land at the Geneva Motor Show.
