The warm hatch of the original Clio range was the RSi: its a 1.8 8v pushing 110bhp and with all the creature comforts. Distinguished by side skirts. Also came in luxury Bacarra trim (95bhp).
The full-on hot hatch was the 16v: 137bhp and a wide-arch body, complete with bonnet bulge/air dam. The Williams was a limited edition variant, with a 2.0 bottom end for better torque delivery. Both mechanically very different from the rest of their Clio family.
Other than that, there werent any other overtly "sporting" original Clios, apart from some special editions like the Maxim - unlike today, when sporty trim can be had with any engine capacity.
The 1.4 RT is a good start though - really good handling and enough poke to keep up with the rep-mobiles and more modern 1.4 16vs. Comes loaded with kit compared to other small cars: all electrics, good trim etc.
