Low figures relate to the least economical version; high to the most economical. Based on WLTP combined fuel economy for versions of this car made since September 2017 only, and typical current fuel or electricity costs.

Fuel economy

Petrol engines 38.2 - 54.3 mpg
Diesel engines 48.7 - 65.7 mpg
  • Outgoing turbocharged engines are efficient and sprightly
  • Ecoflex fuel-saving measures improve economy further
  • Best in the range’s official claim is 85.6mpg

Vauxhall Astra running costs are helped by an efficient range of turbocharged three-cylinder engines. An important thing to note with the Astra range is that CO2 emissions and fuel economy figures vary depending on the size of the car’s wheels. Check that you know exactly what the numbers are if you’re looking at detailed figures, for example if it’s your company car and it could change how much you pay in BIK tax.

Diesels offer lowest running costs

Crowning the range for efficiency is the 1.5-litre diesel and manual gearbox, which promises 62.8-65.7mpg in the 105hp variant. Select the more powerful version with the automatic gearbox and this drops to 56.5-53.3mpg.

CO2 emissions follow suit with 1150120g/km on the manual 105hp and 131-138g/km for the 122hp automatic Astra. None of the diesel-powered Astras are expensive to run.

Petrols not far behind

If you require a petrol model but with efficiency still at the heart of the decision then stick to the 1.2-litre manual in either 110, 130 or 145hp tunes all promise 51.4-54.3mpg, or the same as the worst performing diesel. These also put out between 119-126g/km of CO2. In the real world, the Astra petrol is exceptionally economical when driven gently.

The one to avoid? Unsurprisingly the 1.4-litre turbo with its CVT automatic is the thirstiest with a claimed 47.1-50.4mpg and 129-136g/km of CO2.

Is it reliable?

  • Feels well-assembled from good-quality materials
  • Many of the engines appear in other Vauxhalls already
  • One official DVSA recall so far for an airbag fault

Due to the latest generation’s newness it’s difficult to ascertain exactly how strong Vauxhall Astra reliability will be until there are a significant number on the road. Certainly the early signs are positive – the latest Astra feels like a well-made proposition using higher grade plastics than Vauxhalls of this size of traditionally enjoyed.

The only real question marks at this stage are over the engines, most of which are new or relatively so. Many are already seeing service in other Vauxhalls with no reports of any serious maladies so there shouldn’t be any significant troubles.

According to the DVSA vehicle inspectorate, this generation of Astra has been subjected to one official recall so far to investigate potentially faulty front passenger airbags.
