Our Astra Sports Tourer might be highly specified and sporty, but it must justify its existence on a running cost basis.
Alas, the 125hp 1.7-litre diesel-powered estate has under-achieved in economy terms. Careful monitoring of the fuel used and distance covered computes to an average 46.2mpg, with peaks of 49.8mpg and 52.3mpg flattering to deceive for a model with an admittedly nominal combined official figure of 62.8mpg. Analysis unsurprisingly shows that the peaks involved predominantly motorway mileage.
In the meantime, the lack of a dedicated stop/start Ecoflex Sports Tourer with our 119g/km CO2 power unit imposes inherent consumption and environmental/tax penalties in urban conditions, and is illogical from a fleet perspective as that package is offered on the less tax-efficient 165hp 2.0-litre and less powerful 110hp 1.7-litre diesel counterparts.
Vauxhall Astra Sports Tourer 1.7 CDTi SRi | Mileage | 3762 | Claimed combined consumption | 62.8mpg | Our average consumption | 46.2mpg | Forecast CPM | 54.7p | Actual CPM | 58.1p | Why we’re running it | To see if the latest Astra wagon can shake off its predecessors’ stigma of being a utilitarian workhorse. | Positive | Parking sensors for night manoeuvres | Negative | Real mpg is well behind official stats |
