European markets will get a choice of five engines across both ranges, while the Fabia also gets an entry-level 44kW 1.2-litre petrol.
Three other tunes of the 1.2-litre unit come with 51kW, 63kW and 77kW output figures, while the two 1.6-litre diesels produce 66kW and 77kW.
Skoda has confirmed that all engines are Euro 5 compliant with both TDIs featuring standard particulate filters and CO2 emissions figures below 110g/km.
When teamed with the dual-clutch seven-speed DSG transmission, the most powerful 77kW 1.2 TSI uses just 5.3 litres/100km in combined cycle conditions.
Visually both models appear more confident and purposeful. The radiator grilles have been redesigned and the 3D-shaped headlamps widened for a more dynamic look.
But Skoda Australia’s Karl Gehling said neither model is a certainty to arrive in Australia, with the brand currently assessing its future line-up plans.
“[The Roomster is] just a very small volume product for us at the moment and we are currently looking at whether we keep it in the line-up,” he said.
Skoda failed to sell one Roomster in January in Australia.
“Our focus is to get the Yeti here and then we’re looking at the Fabia as our next model that we’d like to add to the line-up.“We hope to have [Yeti] here by the end of the year and we are very hopeful to have confirmation of that soon,” Mr Gehling said.
The 2010 Skoda Roomster and Fabia ranges will be on display at the Geneva Motor Show from March 2.
