I don't think this will be a Metro / Swift clone - its
got a turbo, so think more an equivalent to the VW TSI and the similar GM unit but made smaller - sort of an upsized FIAT TwinAIR.
If you want a new Swift / Metro then that is the Aygo / 106 / C1 or indeed the Suzuki Alto / Nissan Pixo as an alternative. Both are 1.0, ~70hp, 100mpg, 0-60 in 11-13 seconds and 50+ mpg.
And the Aygo has the same safety rating as the Yaris, but is ~150kg lighter (Yaris 1.0 = 1035kg, Aygo 890kg).
