Just days after launching a new B-segment two-seat coupe cabriolet called the Wind, that looks like an ideal replacement for GM's now defunct Opel/Vauxhall Tigra, Renault has revealed its redesigned C-segment Mégane four-seat drop-top - the range's sixth body style. Like its predecessor the latest car has a large, folding, electro-hydraulic, two-piece, glass roof.
