All Vauxhall Astra models are impressively eco-friendly, with excellent figures from the 109bhp 1.6 CDTi diesel

With many Astras still selling to fleets, having a sub-100g/km CO2 emissions figure is vital. The Astra 1.6CDTi 109bhp model smashes that with a claimed emissions figure of 88g/km – which equates to a claimed mpg average of an astonishing 85.6mpg. Of course, real-world figures are likely to be very different, but unless you go for a Toyota Auris Hybrid, with its 79g/km figure, only a Peugeot 308 manages to match the Astra’s figures.

The more powerful 134bhp 1.6 CDTi diesel will also dip under the 100g/km figure for lower company car tax figures when it’s on smaller 16-inch wheels, but the 1.0-litre three-cylinder petrol turbo model is mighty close to that figure in certain specs and will save you 3% on your company car tax benefit-in-kind.

As with most rival manufacturers, Vauxhall offers service plans on the Astra, with fixed monthly payments for the length of plan, allowing buyers to budget more easily. The Gold plans also incude a courtesy car and full AA cover.

Insurance groups 

Insurance groups are on par with those of the Astra's rivals, especially with the strong raft of safety and security kit the Astra gets as standard. If the car’s fitted with the OnStar connectivity system (standard on SRi models and above, and optional elsewhere), that includes full vehicle tracking in the event of theft. However, this system will no longer work after 2020, so the benefits will be brief.


The Astra has never been a particularly strong performer when it comes to depreciation, due to the numbers finding their way onto the market and the fact that the old car was never a class leader.

The latest model is proving to be much better – although we’d expect the current predictions to soften over time. Being first with new tech on the market will mean that the Astra will be first with new tech on the used market, too, which will contribute to better residual values than the old model.
