• Average fuel economy is a claimed 60+mpg
• Servicing will be about as cheap as it gets
• Insurance group is slightly higher than regular Viva

The Vauxhall Viva Rocks returns a claimed average fuel economy figure of 60.1mpg that, in isolation, looks perfectly acceptable. However, when you consider that the regular Viva achieves 62.8mpg the Rocks’s return appears less impressive, especially when considering how minor the tweaks are.

Tax and servicing costs will be identical, however the Viva Rocks also loses out to the regular Viva with a higher insurance group (group 5 compared to as little as group 3).

While the difference in running costs between the Viva and Viva Rocks are marginal, you have to remember that over three or four yours of driving the car it could add up to make a noticeable difference. 

• No hybrid or electric version
• Average emissions levels from petrol engine
• Slightly more than regular Viva 

The only engine available in the Vauxhall Viva Rocks produces 106g/km of CO2, compared to 104g/km from the regular Viva. Not a huge difference, but could cost you more if you’re running the Viva Rocks as a company car.

There aren’t any plans for a hybrid or pure electric model, so expect the Vauxhall Viva Rocks’s emissions to stay as they are for the car’s production run.

• Comparatively little to go wrong on the Viva Rocks
• Based heavily on the regular Vauxhall Viva…
• that has only one recall against its name

With much of the car based on the regular Vauxhall Viva – a model with only one recall against its name – the Viva Rocks should have no serious reliability concerns. Vauxhall usually has a decent record for reliability in general, and if anything does go wrong (and isn’t covered under the warranty) it shouldn’t cost the earth to fix.

While the interior of the Viva Rocks may not be that premium, it does feel reasonably sturdy and hardwearing, so shouldn’t have any problem standing the test of constant use.
