It used to be that a convertible was a convertible. The roof might be automatic or manual, but that was just about that. But now there are all sorts of systems. Take a look at the roof mechanisms on the
Renault Wind or the
McLaren 12C Spider and you'll see what we mean.
Lamborghini has tried all kinds. The Diablo VT Roadster had a removable roof panel that could be stowed on top of the engine. The Gallardo Spyder features a more conventional fabric top. The Murcielago Roadster had a flimsy and convoluted umbrella-like contraption.
