Astra-nomy lesson, anyone?

Opel Astra TwinTop

"Relationships," as my best friend once put it, "are all about compromise". He also said this: "Two people might share the same aspirations, but the reality of it is that they're both still two independent people with differing personalities."


Well, the same point applies to a convertible - it may be one car, but because it can be driven with the top up or down, really is like two personalities having to share the same chassis. The "top up" mode always had to compromise with its "top down" counterpart.

But with the advent of folding metal hardtops, the great convertible compromise is slowly eroding. Manufacturers have enabled topless convertibles to turn back into regular coupes. The structural rigidity of a hardtop may not be able to match a fixed-head coupe, but it will no doubt be stronger when compared to the rigidity offered by a soft top.


The Astra TwinTop is not a bad looking car to begin with. Compared to the more run-of-the-mill looking Astra sedan, the TwinTop has less chrome on the front fascia. It gets a sportier looking front grille and air dam, with a mesh design. The TwinTop has also been given a pair of nicer looking headlamps with clear lenses, with each headlamp incorporating a tri-bulb design.

As you move down the car's flanks, the two-door layout and prominent shoulder line gives one the impression that the TwinTop is longer than the Astra sedan. With an overall length of 4,476mm however, it is in fact 111mm shorter than the sedan.

The TwinTop's wheel arches are also more pronounced, giving the car a more athletic stance. This impression of sportiness is further enhanced by the 17-inch alloys wrapped in 225/45 series Yokohama S.drive rubbers.

Over at the rear, the TwinTop is endowed with more modern tail lamps, along with a sporty-looking exhaust. The car looks tail-heavy when viewed from the side, but despite this, there is an overall blend of sleekness and athleticism when the TwinTop is viewed as a whole.
