The only thing that makes sense for any automaker to do when they have a best selling vehicle on their hands, is to come up with a fun to drive variant of that very vehicle. So after the German arm of General Motors, Opel, revealed the first details on the 2010 Opel Astra hatchback version; it only made sense that the automaker announced plans for a drop-top two-seater version of the best sold Opel ever.

The new Astra Roadster will replace the current TwinTop and will compete with other lightweight open air sports cars like future Scirocco CC, Audi TT Roadster and Mercedes SLK.

The top of the line version of the new Astra Roadster will get a turbocharged 2.0 Liter engine that will deliver 270 HP and make this particular Astra able to sprint from 0 to 60 MPH in just 6 seconds before reaching a top speed of 150 MPH. Opel is also planning on releasing another version will get a downsized and turbocharged 1.4 Liter petrol burning unit for economy making 150 HP as well as an alternatively fueled 170bhp 2.0 Liter CDTI turbodiesel engine.
