What are the running costs?

The running costs of the Astra promise to be low compared with its rivals, as Vauxhall is keen to appeal to the pockets of retail buyers. What that means is that it’s offered with a range of economical petrols and diesels, while servicing and warranty packages are typically low.

If you’re looking for the lowest overall fuelling costs, you’ll undoubtedly head for the 130hp diesel model, which shares its engines with various small Peugeots, Citroen and DS models, and not only produces low CO2, but offers an easy 60mpg in real-world driving.

The petrol models aren’t far behind in terms of CO2 emissions and whether you choose the 110 or 130hp version expect 45mpg in give-and-take driving and an easy 50mpg-plus on gentle motorway runs.

Finally, the plug-in hybrid is the one to go for if you’re a company car driver, thanks to offering the lowest BIK rates of all models. As with all PHEVs, what you get out of it depends on how often you plug it in.

If you have a 50-mile commute or less and plug it in at night, expect 150mpg and more (plus electricity costs). However, on longer runs, once that battery is flat, 40mpg is a more realistic expectation. Recharging at home with a 7kW wallbox takes up to four hours.

Servicing and warranty

What you see is what you get with Vauxhall servicing and warranty. There are lots of dealers, parts and labour costs are competitive, and a number of service packages are available for those who want to spread the cost, and further help keep costs in check.

Warranty is three years and 60,000 miles, which you can extend to four or five years at an additional cost. Compared with seven years offered by Kia and MG and up to 10 for Toyota’s Relax scheme, Vauxhall’s warranty is at the lower end of generous.

Reliability

  • A new car, but tried and tested running gear
  • Vauxhall’s record is improving
  • Engines and transmissions are reliable

It’s an all-new car not yet delivered to UK customers, so there’s not much to say at this point. This is more relevant than ever as this generation shares nothing with the last Astra, and more with a selection of Stellantis (Peugeot, Citroen and DS) cars that have been around for a while now.

So, the three-cylinder petrols and four-cylinder diesels are dependable, and are throwing up few problems in service. However, the plug-in hybrid is much younger, and there’s little to report here. We’ll keep you posted, though.
