Fuel economy

A more stringent standard for fuel economy (WLTP) was introduced from September 2017, and this model was not required to undergo that test. Its fuel economy measured under the previous test system was 31 - 42 mpg. However these figures are less likely to be achievable in real world driving and so should never be compared to another car's mpg which was measured under the newer, more realistic WLTP system.

Although early models are cheaper to buy, newer models are better value for money, as Vauxhall lavished them with goodies in order to compete with the arrivals of the hardtop Peugeot 307 and Megane Cabriolet. Servicing costs are reasonably priced but insurance is steep, ranging from group nine for the 1.6, to sixteen for the potent 2.0-litre 16-valve Turbo.

Astra scores reasonably on the eco front. With an average of 195 g/km CO2 across the range, its emissions are fairly standard for a small family convertible. It's worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is not particularly economical, averaging 35 mpg.

We haven’t heard of any major issues reported with the convertible, and, unlike some soft-tops, the electric roof mechanism seems to be dependable and well built.
